Children as Caregivers

“It’s my responsibility,” he told me. “We’re family.” His name is Joel and he is 11. His 13-year-old brother, Scott, feels the same way, explaining that it’s “just something you do, you take care of each other.” This is not an uncommon theme in children when they live with someone who has a physical disability or a chronic illness. Whether it’s a parent, step-parent, grandparent, sibling or non-relative, children also take on the role of caregivers, though this role is frequently less distinct than that played by the adults in the home. However, children are no less affected by the life changes that come with caring for someone with chronic illness or disability, and recognizing the effects that this situation has upon them is the key to helping young people cope with the stress and uncertainty that often accompanies it. This may be particularly challenging since much of the time the person needing care is a parent..

“Disability” and “illness” can take many forms, from a sudden injury which forces changes in mobility, such as a spinal cord injury or fracture of a limb, to more insidious medical illnesses like MS, rheumatoid arthritis, or cancer.

Alcoholism and drug abuse are also forms of illness which have their own unique reverberations in the household, and each has effects upon the child in different ways. The way each child reacts and copes with the medical situation is largely based upon their personality and prior life experience. According to one person interviewed who was a caregiver for her mother and siblings following her father’s death, “you get through it.” Now a Social Worker, she feels that “those who are not ‘strong enough’ may go on to marry early to get out of the situation, or find themselves in unhealthy relationships” where they are dominated by a stronger personality. She also stated that “it’s just what you do,” and this is a common comment made by those who found themselves in a caregiving role when they were young.

Caregiving takes many forms, from helping with younger siblings to performing household tasks normally completed by an adult, such as cooking or providing personal care to the disabled or ill person. Often, the receiver of the care is an adult, which places the young person in a precarious position of being a child, essentially performing parental functions for an adult. This can result in role conflicts within the child, and changes the dynamic in the parent-child relationship. In interviewing those who had entered into the role of caregiver at an early age, it was notable that none of them initially indicated feelings of resentment at their situation. Like Joel and Scott, it came as part and parcel of being a family, but there is a cost.

Despite this apparent acceptance of their ill-defined role, children demonstrate recognizable physical and emotional responses to their situation. These can include, but are not limited to: changes in social behaviors, decline in school performance, decreased participation in previously enjoyable activities, mood disturbances, increased fatigue, personality changes and “escape” behaviors, such as self-isolation. Changes in social behaviors can be seen in the way they interact with both adults and other children. Some use more adult language, engaging adults in social situations rather than persons of their own age, while others appear to regress or demonstrate attention-seeking behaviors such as baby talking, excessive crying or thrill seeking. School performance changes can result from preoccupation or worry about the ill or disabled person, though this is generally more prevalent at the beginning of the changes at home than when the situation is long-term. Behaviors which are disruptive in social situations affect school, as well, and the child may talk in class, become tearful, or pull pranks which land them in the principal’s office, or which require that the child be sent home, as a conscious or unconscious attempt to regain their child role.

Children generally tend to be self-focused. With the addition of the illness or disability, that focus necessarily and abruptly changes to one of helping others. Rather than indulging in their usual enjoyable activities, they may decline invitations for age-appropriate activities because they need to “go home and help mom” or whoever they are assisting at home. This increased sense of responsibility, though somewhat overdeveloped due to the unique situation in which they have been placed, overtakes the drive to seek personal enjoyment.

Mood swings can also be evident in some youngsters. A sense of loss of control, fear, or guilt that they may have been the cause of the illness, or if they have suffered a significant loss can manifest themselves in very strong feelings. Incidents that would not have warranted even a mild response can become gigantic and the focus of these strong emotions may result in verbalized and sometimes displaced anger. This anger is rarely directed at the object of the feelings, however, which makes it difficult to diagnose and, subsequently, challenging to address. And, as children have generally less sophisticated ways in which to communicate their feelings, they may express them as behaviors.

Fatigue can be an emotional or physical manifestation, with the pressures of school, combined with greater duties in the home, and the stress of taking on a parental role in the care of the ill person. The child may not fall asleep easily, have trouble staying asleep, or wake up early, “thinking.” Personality changes can be related to sleep disturbance, internalized guilt or resentment, response to stress chemicals in the body, or a change related to how the child “thinks” they should be acting. Assuming the role of caregiver plays directly into the role-conflict—am I a child or am I an adult?

Escape behaviors such as reading for hours, spending inordinate amounts of time alone in his/her room, taking long walks, or plugging in a headset is a means to get away from the demands of being a caregiver. Although not necessarily a negative behavior as it provides the child with an outlet, it can be detrimental if it adversely affects the child’s ability to relate to others or interferes with concrete interactions. Since feelings of isolation can already be present in the situation, self-isolating behaviors may reinforce the feelings of being alone and can potentially lead to significant depression, which compounds the already-present feelings of loss. Most children get through what usually amounts to a brief time of caregiving without lasting, negative effects.

Generally resilient, most children adjust adequately to the temporary life change and go on without residual problems. It is important, however, to recognize that children grieve, too, and that grief is not limited to death and divorce; life changes of every kind can elicit a grief response, which is just as powerful in children as in adults, and is generally less understood. Like adults, children grieve in their own ways. Many of the emotional and physical changes that are seen as attributed to adjustment problems or reactions to being a child caregiver are, in fact, indicators of grief. Being unable to effectively express these feelings, or lacking the ability to understand what they are feeling, increases the frustration and isolation.

Former child caregivers have related that once they reached adulthood, they found themselves sometimes emulating caregiving in their personal and professional relationships. Many that I interviewed chose helping professions such as nursing, Teaching or social work. This is consistent with the personality traits required of a caregiver of any age. Knowing the effects of caregiving on a child, we can better understand how to help our children cope with the intense feelings associated with living with someone else’s illness or disability.

First and foremost, communicate with the child. They need to know that they are not responsible for the adult’s or sibling’s condition. Guilt plays a significant role in a child’s desire to step into the caregiving role. Providing simple and understandable information about the condition, and answering their questions, goes a long way to resolving guilt feelings, as well as easing fear based on the “unknown.” Scott said that though he sometimes was afraid that his mother would die, he did not share his feelings with Joel. He explained,”I don’t want him to worry any more than he already does.” Scott was dealing with the “unknown,” while protecting his brother from it; however, he didn’t realize that Joel was doing the same thing. It is OK to talk about the illness or disability, but don’t make it dinner time conversation every day. Children are very aware of changes in their environment and usually know, without being told, that something is “wrong.” Talking about every ache and pain only reinforces that the parent needs “help,” and further engages the child into the caregiving mode. Instead, talk about everyday things. This reassures the child that the life they know is still going to go on, despite the change in health of their family member.

Second, though it is often easy to accept the help of others when we are ill, it is vital for children in this type of household to have the adult remain as independent as possible, and that they rely on available adult help. This diminishes the role-conflict that can arise when children take on adult responsibilities. Utilize the children in performing age-appropriate tasks, such as folding their own clothes, feeding pets, taking out the trash or loading the dishwasher, and save the more adult responsibilities, such as medication administration, dressing changes, and providing personal hygiene, for the adult caregivers. Utilize outside resources to supplement in-home care to keep child caregiving to a minimum.

As difficult as it can be when illness or disability enters into a home, there needs to be equal focus on both the needs of the child and the needs of the person who is ill. Achieving a balance between each person’s needs allows the child to focus on age-appropriate issues such as school, interactions with peers and personal growth, without nurturing feelings of guilt over not “doing more” with respect to the ill or disabled person in the home. Verbalizing interest in the child’s life provides positive reinforcement for development of interests outside the home. This can also help to decrease mood changes associated with fear or loss of control, as they have the opportunity to succeed outside the home environment with the support and approval of those in the home.

Escape behaviors come into play when the child has to devote a large amount of time providing care for the ill or disabled person, or is having difficulty coping with the change in role. A means of coping, these avoidance behaviors serve to de-stimulate the child and insulate them from their feelings. By changing their role from “caregiver” to one of “member of the household,” there is no need for avoidance of what could be an intensely emotional situation. Though normal self-isolation behaviors may occur, they are less likely to be in response to feelings of stress related to the illness or disability.

Children are affected by illness in the household, just as it affects others in the home. When young people are put into the role of caregiver, there can develop a role-conflict and changing dynamic in the parent-child relationship that can manifest itself in both emotional and physical ways. Understanding the effects of this situation, the grief associated with the change in the home environment, and the stress response in the child can aid in making changes in the expectations of children in this setting, and help them cope and respond in a more positive and age-appropriate manner to this unique and challenging situation. Joel and Scott agree with this. How do I know? I am their mother; I have fibromyalgia and I had a stroke at the age of 37.

Exercise Improves Cognition in Parkinson’s Disease

It’s well known that exercise invigorates both body and mind. Exercise studies in Parkinson’s disease (PD) have shown improved mobility and quality of life, and possibly slower rate of disease progression. But what can exercise do for memory and thinking (cognition), which can be affected to different degrees at different points in the course of Parkinson’s?

Recently, a group of researchers answered that question by reviewing exercise and cognition studies conducted in people with Parkinson’s over the past 10 years. They confirmed the benefit of exercise on cognitive function in people living with PD.

For this study, researchers analyzed nine randomized controlled trials from several countries. The participants of these trials were, on average, 60 to 74 years old, diagnosed with Parkinson’s six years prior and living with mild to moderate disease. Exercise programs varied in length, number and duration of sessions, and included studies with a treadmill, stationary bicycle, stretching and strengthening (with and without a Wii Fit exercise program), tai chi and tango. Volunteers’ cognitive function was tested throughout each study to see if the exercise had an effect.

Of the specific exercise programs reviewed, tango, stretching and strengthening with a cognitive component (a Wii Fit exercise program), and treadmill training had benefits on cognition. The latter — walking at a person’s preferred speed or slightly slower for about an hour three times a week for 24 weeks — boosted cognitive function more than the other two exercise programs.

More support for exercise, and treadmill exercise in particular. But this doesn’t mean that treadmill walking is the best exercise for Parkinson’s. Many questions remain about the optimal type, amount and intensity of exercise to keep cognitive (and other) symptoms at bay. Larger, well-designed studies can help provide answers and clarify effects.

Multiple forms of exercise for many symptoms are currently being investigated. Register for Fox Trial Finder to match with recruiting trials. As researchers work to define the ideal exercise for your Parkinson’s, continue regular exercise that you enjoy.

Understanding Parkinson Disease Psychosis

If you are the caregiver of someone with Parkinson’s disease (PD), you are likely well aware of the common motor symptoms associated with the condition, like tremors. However, you may not be aware that non-motor symptoms (those unrelated to physical movement), such as psychosis, commonly develop as the disease progresses. These symptoms should not be overlooked.

What is Parkinson’s Disease Psychosis?

As PD progresses, up to 40 percent of the approximately one million Americans living with the illness will develop psychotic symptoms, primarily hallucinations, but also delusions. These symptoms can be an indication of Parkinson’s disease psychosis (PDP), but unfortunately, many patients are not diagnosed. Sometimes, the symptoms of PDP are misdiagnosed as a co-morbid condition. Other times, patients and their families may not be comfortable sharing the symptoms with their physician team.

What Causes PDP?

Though definitions can vary, the term psychosis generally means “loss of reality testing.” Psychotic symptoms may be brought on by infections, typically bladder or pneumonia, but are often caused by medications. These are usually the ones used in treating PD, but other medications, particularly narcotic pain medications and many of the drugs used to treat an overactive bladder, may cause symptoms as well. When infections have been ruled out and no other medication has been identified as causing the psychosis, then the most likely culprits are the PD medications. It’s also possible that PDP might be a naturally occurring complication as the disease progresses.

There are a couple of things to keep in mind here. One is that the symptoms may begin even though PD medications have been constant over several months, or even years. The problem may not necessarily be triggered by an increase in PD medications. The reason that a stable medication regimen can begin causing hallucinations is that the PD is always progressing, making patients more sensitive to possible drug side effects. The second principle to keep in mind is that it may not be one drug that is the cause, but the combination of all the PD medications.

Hallucinations

Many PD patients have occasional, or not so occasional, symptoms that are often seen in people who lose their ability to separate reality from fantasy. These are most commonly hallucinations, which are false perceptions in one of our special senses (vision, hearing, taste and touch). For example, it’s quite common for patients to report seeing other people, often children, who are sitting or standing in the room, ignoring them. Another commonly cited experience is that a patient who is watching TV or reading a book notices two strangers sitting on a sofa talking to each other, but they make no noise. The patient talks to them, and they ignore him. When he gets up to approach them, they disappear. A few days later, this happens again, and after one or two episodes, the patient no longer pays attention or tries to contact them. These types of hallucinations tend to occur more at night than during the day and are usually the same each time.

Some of the images may be entertaining, but usually are just a little bit annoying. The hallucinations may look real, appear to be black and white, fuzzy or sharp and sometimes, the people may look somewhat odd, like cartoons.

Auditory hallucinations, or hearing things that are not there, are about half as common as visual hallucinations, and they tend to be less distinct than the visual hallucinations. Patients may hear a radio in another room, a party going on across the street or voices talking in the hallway. Less common are tactile hallucinations (e.g., feeling things on the skin), olfactory (e.g., smelling an aroma not detectable to others) and taste hallucinations.

Other Types of Hallucinations

In addition to persistent or repeated visual hallucinations, a PD patient might also see a fleeting image out of the corner of their eyes, like a cat or a shadow passing by, but when they turn to look, there isn’t anything there. Sometimes they see slight flashes of light, which are very much like reflections off their eyeglasses.

Another type of experience is called a “presence hallucination,” which is not really a hallucination. With a presence hallucination, patients have a strong feeling of another person, or an animal, being behind them or to the side, but when they turn around, there isn’t anything. This feeling usually isn’t scary, as the patient doesn’t feel they’re about to be attacked. However, this is a strong feeling – something most people have experienced on occasion – but in this case, it’s experienced more frequently and more strongly.

Delusions

Delusions are false, irrational beliefs. In PDP, delusions are more bothersome, but less common. Also, in PDP, the delusions tend to be fairly similar from one patient to the next and are usually paranoid in nature. For example, a patient might be positive that his spouse has been attacked and is in need of assistance. Or, a spouse may be irrationally convinced that their partner is committing adultery.

Susan’s Story

Sadly, after a 20-year battle with PD, Susan’s father, Gary, passed away in April 2014 at the age of 74. Because Susan resides in Las Vegas, her mother, Marjorie, was her father’s primary caregiver in Iowa. Susan stayed actively involved by providing her mom with emotional support, particularly in later years when her father developed PDP.

Susan and her mother believe that Gary’s PDP started after a hospital stay resulted in changes to his medication doses. At that time, Gary began to experience strange and disturbing delusions, often in relation to his wife’s safety. For example, on several occasions, he called the police, convinced that “weirdos” had entered the house to sexually assault Marjorie. He once even drove himself to the police station to report the perceived crime. Also disturbing, Gary would see kittens frolicking and then get upset when he thought he saw them die because he “forgot” to feed them. Other hallucinations included seeing strangers in his bed or with him in the shower. Despite telling Gary that his visions were not real, Susan and Marjorie often could not convince him of the truth.

Susan’s mother was emotionally exhausted and stressed from caring for Gary, whom she had been married to for 48 years. The idea of seeking more help for him was overwhelming, given the time she already gave to physical therapy and day-to-day care. Her life already revolved around Gary’s illness. Susan tried to encourage her mother to speak to her physicians about Gary’s visions, but her mother was embarrassed. On the other hand, both also wished the physicians had asked if these symptoms were occurring.

PDP’s Impact on Caregivers

As Susan’s story demonstrates, PDP is difficult for both the patient and their caregivers, particularly because it is impossible to convince someone who is experiencing delusions regarding the truth of their circumstances. Logic does not penetrate.

In fact, accusations of spousal infidelity are often the “last straw” and when caregivers find caring for their loved one too overwhelming. One of the major problems in dealing with PDP is that the patient and the family often try to hide the problem – the patient for fear of being thought “crazy” and the caregiver due to embarrassment. The reality is that when a PD patient has psychotic symptoms, his or her mental abilities will be otherwise normal. The patient may not be disoriented, can still balance their checkbook and recall everything they’re supposed to know. When hallucinations or delusions occur, the treating doctor should be notified. No irreversible harm will occur if treatment is delayed, but it is unlikely the problem will go away on its own.

Treating PDP

Hallucinations don’t always need to be treated. If these symptoms often don’t bother the patient, then they don’t need immediate attention, but they should always be monitored. Yet, hallucinations also indicate toxicity, hence PD medications cannot be increased without worsening of the hallucinations, and therefore, physicians may limit treatment. When the psychotic symptoms require treatment, the doctor may first reduce PD medications, and when these cannot be further reduced, they may prescribe something else.

Support Your Loved One and Yourself

PDP is also associated with increased caregiver stress and burden, nursing home placement and increased morbidity and mortality. But, your loved one is certainly not alone in living with PDP, and an effective management plan can improve the complication. Seek out the support that he or she needs, but also make sure that you are getting the emotional care you personally need in order to be an effective advocate for your loved one.

12 Medication Management Tips That May Save Your Life

What can be done to help older adults take medications safely? Take care to avoid some of the more common medication mistakes, such as taking drugs incorrectly or taking more than is prescribed. Pill dispensers, organizers and even reminder services can also be useful tools for some.

That being said, nothing substitutes for responsible caregiver advocacy and being proactive about the drugs we and our loved ones are taking.

Here are some other tips to keep in mind:

1. Ask your provider if the dosage is age-appropriate.

Because of the way our bodies metabolize various drugs as we get older, seniors can be more sensitive to some drugs and less sensitive to others. They are also more likely to experience adverse effects. Double-check with your doctor or pharmacist to ensure that the dosage on the prescription is age-appropriate, and ask if it’s advisable to start with a lower dose and taper upwards.

2. Be aware of medications deemed unsafe for seniors.

The Beers Criteria for Potentially Inappropriate Medication Use in Older Adults, put together by the American Geriatric Society, is a list of medications that older adults should avoid or use with caution. Some pose a higher risk of side effects or interactions, while others are simply less effective.  For instance, commonly prescribed sedatives in the benzodiazepine category, like diazepam (Valium), are on the “avoid for certain conditions” list because older adults may be more sensitive to these drugs. Ask your pharmacist if any of your loved one’s medications are on the caution list, and whether you should be concerned.

3. Bring a medications list — or the medications themselves — to the doctor with you.

Take your list of prescription medications —  a list of over-the-counter drugs and any herbal supplements you might be taking — and bring it to the doctor’s office with you, or to a pharmacist. The more information your provider has, the more accurately they can pinpoint any potential adverse effects or drug interactions.

4. Check on prescriber behavior in Prescriber Checkup.

Rather alarmingly, Medicare may not monitor prescription safety as effectively or as closely as we might like, as noted in a ProPublica report. “In 2010 alone, health-care professionals wrote more than 500,000 prescriptions for the drug [carisoprodol] to patients 65 and older,” says the report — a drug that was pulled from the European market in 2007 and is on the Beers caution list. If you have concerns about a provider, or if you simply want more information about the drugs prescribed in your area, check ProPublica’s online Prescriber Checkup tool.

5. Closely monitor medication compliance in the cognitively impaired.

If your loved one shows signs of confusion about their medications, or has been diagnosed with cognitive impairment, Alzheimer’s disease, or another form of dementia,  do not allow them to manage or take their own medications. If they are simply having trouble tracking their medications, a reminder system may be helpful, but the situation is more serious if your loved one is cognitively impaired. Taking medications incorrectly can be harmful or fatal.

6. Create and maintain an up-to-date medication list.

American Nurse Today says, “keep an accurate list of all medications, including generic and brand names, dosages, dosing frequency and reason for taking the drug.” This can help reduce the risk of polypharmacy.

7. Get a second opinion if you are uncertain.

Not all providers are alike, and there are, unfortunately, some doctors who prescribe medications inappropriately, in excess, or for unapproved uses. If you are concerned about a prescription or a diagnosis, don’t be afraid to seek out a second opinion.

8. Know the side effect profile of your medications.

Knowing the potential side effects and interactions can help you stay alert to any health changes that may occur in response to a new medication or combination of medications. If you do notice health changes, contact a physician right away. Some side effects can mimic other health conditions, including dementia, so make sure to bring a list of your medications to every doctor visit. This will help the provider properly diagnose the problem — and help the patient avoid unnecessary or dangerous medications.

9. Make sure the pharmacy label says why you are taking the prescription.

This is particularly important for older adults who are taking multiple medications, to ensure that they know what each medication is for and how to take it properly. It can also help caregivers police whether their loved one is being given too many medications to treat the same issue, or whether a less scrupulous provider has prescribed a drug for a purpose it wasn’t intended to treat.

10. Minimize the number of providers and pharmacists you use.

Keeping the number of doctors and pharmacies to a minimum is better for you and better for the providers who must coordinate care. “The primary-care provider and specialists must maintain good communication with each other to prevent or minimize problems,” says American Nurse Today. They also advise people to “use only one pharmacy to obtain medications; this adds another level of review to help ensure appropriate dosage and reduce the risk of adverse drugs effects and interactions.”

11. Talk to the pharmacist and ask questions.

If you have any concerns at all about the combination of medications you or your loved one is taking, or how a new medication will affect you, ask your doctor or pharmacist. Learn about the potential dosage, proper storage, side effects and anything else that will help you take medications correctly. You should also talk to your provider if you are thinking of stopping a medication.

12. Tell your provider about any previous adverse drug effects.

This one might go without saying, but if you or your loved one has had a bad reaction to any medication in the past, let your doctor and pharmacist know.

Sleuth-ebrating the Holidays

This holiday season can also be a time to be a loving (but slightly nosey) detective. If you are traveling to visit your loved ones who may be in need of care, the holidays afford an ideal time to assess any changes in their health and well-being.

As any good detective knows, the first step is to follow the clues.

Clue One – Your loved one’s home:

  • What condition is it in? Is it a clean, clutter free and safe environment?
  • The kitchen is where you can find a lot of telling clues. Look for signs of spoiled food, or an excess of junk/convenience foods compared to the last visit. This may be a sign they have stopped cooking.
  • Is the bathroom safe, with grab bars (if necessary) and slip proof mats? Are cords dangling dangerously near running water?

Clue Two – Your loved one’s behavior:

  • How do they handle their medication regimen? Are they using expired medications?
  • Is your loved one acting withdrawn, or making excuses not to participate?
  • Are there noticeable changes to hearing, sight or speech?
  • What is their balance like? Are stairs becoming an issue?
  • Observe memory capabilities. A good way to check this is to see if a loved one is remembering to pay bills, or keep appointments.
  • What are your loved one’s grooming habits like?

Once your detectiving is done and you have a clear picture of your loved one’s living situation, it is time to assess if you need to take further next steps in providing additional care for them.

  • What services (appointments, shopping, banking, etc.) do they need access to on a regular basis?
  • Is your loved one still able to drive? Don’t just take their word for it.
  • What socialization opportunities exist in the community to help prevent isolation and depression?
  • Is another family member or close friend living nearby and able to help?
  • What local help is available?

Before making any big changes, it’s essential to talk (respectfully) with your loved one about what they see as their greatest needs. Discuss solutions, and then bring some options forward that may work for all involved.

While the holidays may be overwhelmed by gifts and gatherings, it’s also a great time for a long-distance caregiver to take the extra time to observe a loved one’s living situation and address any new needs. The gifts of love can be shared in many ways, even if not wrapped in a box and ribbon.

Predicting cognitive deficits in people with Parkinson’s disease

NIH-funded tool may improve clinical trial design and aid in treatment development.

Parkinson’s disease is commonly thought of as a movement disorder, but after years of living with the disease, approximately 25 percent of patients also experience deficits in cognition that impair function. A newly developed research tool may help predict a patient’s risk for developing dementia and could enable clinical trials aimed at finding treatments to prevent the cognitive effects of the disease. The research was published in Lancet Neurology and was partially funded by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.

“This study includes both genetic and clinical assessments from multiple groups of patients, and it represents a significant step forward in our ability to effectively model one of the most troublesome non-motor aspects of Parkinson’s disease,” said Margaret Sutherland, Ph.D., program director at the NINDS.

For the study, a team of researchers led by Clemens Scherzer, M.D., combined data from 3,200 people with Parkinson’s disease, representing more than 25,000 individual clinical assessments and evaluated seven known clinical and genetic risk factors associated with developing dementia. From this information, they built a computer-based risk calculator that may predict the chance that an individual with Parkinson’s will develop cognitive deficits. Dr. Scherzer is head of the Neurogenomics Lab and Parkinson Personalized Medicine Program at Harvard Medical School and a member of the Ann Romney Center for Neurologic Diseases at Brigham and Women’s Hospital, Boston.

Currently available Parkinson’s medications are only effective in improving motor deficits caused by the disease. However, the loss of cognitive abilities severely affects the individual’s quality of life and independence. One barrier to developing treatments for the cognitive effects of Parkinson’s disease is the considerable variability among patients. As a result, researchers must enroll several hundred patients when designing clinical trials to test treatments.

“By allowing clinical researchers to identify and select only patients at high-risk for developing dementia, this tool could help in the design of ‘smarter’ trials that require a manageable number of participating patients,” said Dr. Scherzer.

Dr. Scherzer and team also noted that a patient’s education appeared to have a powerful impact on the risk of memory loss. The more years of formal education patients in the study had, the greater was their protection against cognitive decline.

“This fits with the theory that education might provide your brain with a ‘cognitive reserve,’ which is the capacity to potentially compensate for some disease-related effects,” said Dr. Scherzer. “I hope researchers will take a closer look at this. It would be amazing, if this simple observation could be turned into a useful therapeutic intervention.”

Moving forward, Dr. Scherzer and his colleagues from the International Genetics of Parkinson’s Disease Progression (IGPP) Consortium plan to further improve the cognitive risk score calculator. The team is scanning the genome of patients to hunt for new progression genes. Ultimately, it is their hope that the tool can be used in the clinic in addition to helping with clinical trial design. However, considerable research remains to be done before that will be possible.

One complication for the use of this calculator in the clinic is the lack of available treatments for Parkinson’s-related cognitive deficits. Doctors face ethical issues concerning whether patients should be informed of their risk when there is little available to help them. It is hoped that by improving clinical trial design, the risk calculator can first aid in the discovery of new treatments and determine which patients would benefit most from the new treatments.

“Prediction is the first step,” said Dr. Scherzer. “Prevention is the ultimate goal, preventing a dismal prognosis from ever happening.”

This work was supported by the NINDS (NS082157, NS095736), the U.S. Department of Defense, M.E.M.O. Hoffman Foundation, and Brigham & Women’s Hospital.
