Medicine For Parkinson’s Dementia

What Caregivers Can Do Now

Parkinsonâs Disease and Dementia: David Beversdorf, MD

Caring for loved ones with dementia and delusions can be stressful and exhausting.

Even if the FDA approves pimavanserin for use in people with dementia, it could be months away from being available.

What are some rules of thumb caregivers should follow? When do you need to reach out to your doctor?

We put those questions to Dr. Verna R. Porter, a neurologist and director of dementia, Alzheimers disease, and neurocognitive disorders at Pacific Neuroscience Institute at Providence Saint Johns Health Center in Santa Monica, California.

You certainly want to call your doctor if this is the first time these hallucinations or delusions have happened, she told Healthline. Or if they are happening more often and are starting to last longer.

Porter said caregivers should look for signs that their loved one is more easily distracted or forgetful, has less energy, and exhibits sudden changes in personality and behavior. They may be strangely emotional, rambling, not making sense when they talk.

And you should be concerned if you are worried the patient will hurt themselves or others, she added.

The Alzheimers Association has some tips on how caregivers can cope and a 24/7 helpline to connect you to resources in your community.

What Are The Surgical Treatments For Parkinsons Disease

Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.

What Should I Do If I Forget A Dose

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

If you miss taking rivastigmine for more than a few days, talk to your doctor before starting to take it again. You will probably have to restart taking it at a lower dose.

Are There Medicines To Treat Pdd

Though there is no cure for PDD yet, there are medications that help manage the symptoms. These medications are called cholinesterase inhibitors, and they can help if a person with PDD is having memory problems. Some examples of these medicines are donepezil, rivastigmine and galantamine. Sleep problems may be managed by sleep medications such as melatonin.

Because people with PDD are usually very sensitive to medications, any new medication, even one that is not being used for the brain, needs to be reviewed with the persons provider to avoid potential contraindication.

    Parkinson’s Disease Dementia Follow

    A person with Parkinson’s disease and dementia requires regular checkups with his or her health care professional.

    • These checkups allow the health care professional to see how well treatment is working and make adjustments as necessary.
    • They allow detection of new problems of cognition, mood, or behavior that could benefit from treatment.
    • These visits also give the family caregiver an opportunity to discuss problems in the individual’s care.

    Eventually, the person with Parkinson’s disease and dementia will likely become unable to care for himself or herself or even to make decisions about his or her care if the patient lives long enough with Parkinson’s disease and dementia.

    • It is best for the person to discuss future care arrangements with family members as early as possible, so that his or her wishes can be clarified and documented for the future.
    • A health care professional can advise patients and caregivers about legal arrangements that should be made to ensure that these wishes are observed.

    Parkinson’s disease dementia prevention

    There is no known way of preventing dementia in Parkinson’s disease. However, patients with Parkinson’s disease are urged to continue to exercise and live a healthy lifestyle as this may delay or reduce the onset of dementia, although there is no good data to indicate this will occur.

    Pharmacological Treatments In Acute And Chronic Conditions

    The Food and Drug Administration warning on the use of antipsychotic drugs has led to better awareness about the risk associated with the use of these classes of drugs in cognitively impaired and older people, including increased mortality .

    The recently published European Academy of Neurology recommendation on the management of issues in dementia, including agitation, reports that individuals with dementia and agitation and/or aggression should be treated with atypical antipsychotics only after all non-pharmacological measures have been proven to be without benefit or in the case of severe self-harm or harm to others . Antipsychotics should be discontinued after cessation of behavioral disturbances and in patients in whom there are side effects .

    Further suggestions for pharmacological management of acute agitation, such as agitation in delirium and chronic agitation in dementia, are depicted in the following sections. Randomized controlled trials are summarized in .

    Antipsychotics Used For Parkinson’s Despite Warnings

    Doctors Still Prescribe Antipsychotics Despite Risks for Some Parkinson’s Patients

    July 11, 2011 — Doctors continue to prescribe antipsychotic drugs to their patients with Parkinson’s disease and psychosis, despite “black box” warnings from the FDA linking them to increased risk of death among patients with dementia, a study shows.

    A black box warning is the strongest drug warning issued by the FDA.

    “My sense is that the black box warnings don’t factor into decision making,” says study researcher Daniel Weintraub, MD, an associate professor of psychiatry at the University of Pennsylvania.

    The study is published in the Archives of Neurology.

    The black box warning for antipsychotics says the drugs are associated with an increased risk of death for those with dementia, which is common among people diagnosed with Parkinson’s. Some commonly prescribed antipsychotics also worsen symptoms of Parkinson’s.

    Risperdal and Zyprexa , for example, are two such drugs, and neither has been shown to be very effective. Yet according to the study, nearly 30% of patients with Parkinson’s and psychosis take them.

    Clozaril , the only drug known to be both effective and well-tolerated for treating psychosis in Parkinson’s patients, is prescribed to less than 2% of those with the disease.

    “Quetiapine is the No. 1 choice without clear evidence that it’s effective,” says Weintraub.

    To Take A Dose Of Rivastigmine Solution Follow These Steps:

    Dealing with Dementia in Parkinson’s Disease
  • Remove the oral dosing syringe that came with this medication from its protective case.
  • Push down and twist off the child-resistant cap to open the bottle of rivastigmine solution.
  • Put the tip of the oral syringe into the white stopper opening on top of the bottle.
  • While holding the syringe straight up, pull up on the plunger to the mark on the syringe that equals your dose.
  • Check the liquid in the syringe for air bubbles. If there are large air bubbles, gently move the syringe plunger up and down a few times. Do not worry about a few tiny air bubbles.
  • Make sure the plunger is on the mark on the syringe that equals your dose.
  • Remove the oral syringe from the bottle by pulling up on it.
  • Swallow your dose from the syringe directly, or mix it with the liquid you have chosen. Drink or swallow all of the solution.
  • Wipe off the outside of the oral syringe with a clean tissue, and put the syringe back into its case.
  • Close the child-resistant cap on the bottle of medication.

    What Are The Symptoms Of Parkinson’s Disease Dementia

    Cognitive impairment in Parkinson’s disease may range from a single isolated symptom to severe dementia.

    • The appearance of a single cognitive symptom does not mean that dementia will develop.
    • Cognitive symptoms in Parkinson’s disease usually appear years after physical symptoms are noted.
    • Cognitive symptoms early in the disease suggest dementia with Parkinsonian features, a somewhat different condition.

    Cognitive symptoms in Parkinson’s disease include the following:

    • Loss of decision-making ability
    • Loss of short- and long-term memory
    • Difficulty putting a sequence of events in the correct order
    • Problems using complex language and comprehending others’ complex language

    Persons with Parkinson’s disease, with or without dementia, may often respond slowly to questions and requests. They may become dependent, fearful, indecisive, and passive. As the disease progresses, many people with Parkinson’s disease may become increasingly dependent on spouses or caregivers.

    Major mental disorders are common in Parkinson’s disease. Two or more of these may appear together in the same person.

    The combination of depression, dementia, and Parkinson’s disease usually means a faster cognitive decline and a more severe disability. Hallucinations, delusions, agitation, and manic states can occur as adverse effects of drug treatment of Parkinson’s disease, this might complicate the diagnosis of Parkinson’s dementia.

    What Future Medications May Be Available For Parkinsons

    There are numerous studies investigating new treatments for Parkinsons disease.

    There has been new information about the role of autoimmunity and T-cells in the development of Parkinsons disease, possibly opening the door to a role for biologics.

    Stem cells are also being investigated as a treatment option for Parkinsons disease.

    What Other Information Should I Know

    Keep all appointments with your doctor.

    Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

    It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

    Consider Drug Risks Versus Benefits For The Individual Patient

    You have to be very careful, and so its super important that clinicians are aware of the differences between these three drugs , the risks and the benefits, and that these are the ones that are applied rather than the classical dopamine blockers, he adds.

    The acetylcholinesterase inhibitors rivastigmine and donepezil can be helpful for psychosis in patients with PD and DLB, and may improve memory as well, according to Dr. Okun. Theres certainly a subset of people with Lewy bodies that do really well with that medication.

    Quetiapine can help patients with sleep, and this could account for some of the benefits it provides for patients with psychosis, he adds.

    Psychosis in DLB can be more challenging to treat than in PD, Dr. Okun notes, because certain medications can make symptoms worse. Persons with Lewy bodies often have what is called cognitive fluctuations, he explains. They can be very sensitive to many medicines.

    Individuals with DLB and PD may also develop a sensitivity to dopamine and dopamine blockers, he adds. Thats more common with Lewy body dementia than it is with Parkinsons disease psychosis, and thats another thing you have to watch out for.

    What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms

    Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.

    Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.

    Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.

    Treatment Of Parkinsons Disease Dementia

    Currently, statistics on cognitive change and dementia in PD come from studying patients who were first diagnosed ten or twenty years ago, prior to widespread recommendations about physical activity and exercise.

    While no treatments have been proven to prevent development of Parkinsons and dementia, there is strong reason to believe that physical and cognitive activity could play a powerful role in slowing disease progression in the early stages of Parkinsons disease and throughout the course of disease.

    Treatment of PDD involves the use of rivastigmine, an oral or transdermal medication that boosts the brains acetylcholine .

    Rivastigmine is the only medication FDA approved for PDD but other medications sometimes used off label include donepezil , also an acetyhlcholine boosting drug, and memantine , an NMDA receptor antagonist.

    Medications for dementia help somewhat, and other treatments may play a role for behavior issues in PDD.

    Research, including clinical trials, is ongoing to find disease-modifying treatments for PDD.

    What Medications Are Used To Treat Parkinsons Disease

    Coping with Dementia in Parkinson’s disease for Care Partners

    Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.

    Medications combat Parkinsons disease by:

    • Helping nerve cells in the brain make dopamine.
    • Mimicking the effects of dopamine in the brain.
    • Blocking an enzyme that breaks down dopamine in the brain.
    • Reducing some specific symptoms of Parkinsons disease.

    Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .

    Coping With Lewy Body Dementia

    Coping with Lewy body dementia involves much more than your treatment plan. Its also essential to have access to social support and a safe home.

    In the early stages of this condition, symptoms are typically milder, and people with LBD can function. However, as the disease progresses, there will be a severe decline in cognitive and motor abilities, and assisted care will be necessary.

    Taking care of your physical healthy by exercising regularly and eating nutritious meals, is also important. Symptoms of anxiety and depression could develop as a result of this condition. Speaking to a therapist who has experience working with people who have dementia, will help.

    Behavioral changes are to be expected with LBD. Keeping a diary to track your triggers and what times of the day you experience changes in your behavior, will help you understand your condition better.

    What Are The Symptoms Of Parkinson Disease

    Parkinson disease symptoms usually start out mild, and then progressively get much worse. The first signs are often so subtle that many people don’t seek medical attention at first. These are common symptoms of Parkinson disease:

    • Tremors that affect the face and jaw, legs, arms, and hands
    • Slow, stiff walking

    What Is Parkinson Disease

    Parkinson disease is a movement disorder. It can cause the muscles to tighten and become rigid This makes it hard to walk and do other daily activities. People with Parkinsons disease also have tremors and may develop cognitive problems, including memory loss and dementia.

    Parkinson disease is most common in people who are older than 50. The average age at which it occurs is 60. But some younger people may also get Parkinson disease. When it affects someone younger than age 50, it’s called early-onset Parkinson disease. You may be more likely to get early-onset Parkinson disease if someone in your family has it. The older you are, the greater your risk of developing Parkinson disease. It’s also much more common in men than in women.

    Parkinson disease is a chronic and progressive disease. It doesn’t go away and continues to get worse over time.
