How Can We Support The Sleep/wake Cycle Of Pdd
For people with PDD who are confused about the day-night cycle, some daily strategies can be helpful. At night, starting a lights out routine that happens at the same hour every day, where all curtains are closed and lights are turned off, can help the person understand that it is sleep time. During the day, opening the curtains, allowing the person with PDD to spend as much time in the daylight as possible, avoiding naps, and organizing stimulating activities, can be helpful. Having lots of calendars and clocks in every room might also help a person with PDD be less confused about the time of day.
Coping With Cognitive Changes
Some medications used to treat Alzheimer’s disease also may be used to treat the cognitive symptoms of LBD. These drugs, called cholinesterase inhibitors, act on a chemical in the brain that is important for memory and thinking. They may also improve hallucinations, apathy, and delusions. The U.S. Food and Drug Administration has approved one Alzheimer’s drug, rivastigmine, to treat cognitive symptoms in Parkinson’s disease dementia. Several other drugs are being tested as possible treatments for LBD symptoms or to disrupt the underlying disease process.
What Is Lewy Body Dementia Causes Symptoms And Treatments
On this page:
Lewy body dementia is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and mood. Lewy body dementia is one of the most common causes of dementia.
LBD affects more than 1 million individuals in the United States. People typically show symptoms at age 50 or older, although sometimes younger people have LBD. LBD appears to affect slightly more men than women.
Diagnosing LBD can be challenging. Early LBD symptoms are often confused with similar symptoms found in other brain diseases or in psychiatric disorders. Lewy body dementia can occur alone or along with other brain disorders.
It is a progressive disease, meaning symptoms start slowly and worsen over time. The disease lasts an average of five to eight years from the time of diagnosis to death, but can range from two to 20 years for some people. How quickly symptoms develop and change varies greatly from person to person, depending on overall health, age, and severity of symptoms.
In the early stages of LBD, symptoms can be mild, and people can function fairly normally. As the disease advances, people with LBD require more help due to a decline in thinking and movement abilities. In the later stages of the disease, they often depend entirely on others for assistance and care.

How Is Parkinson Disease Treated
Parkinson disease can’t be cured. But there are different therapies that can help control symptoms. Many of the medicines used to treat Parkinson disease help to offset the loss of the chemical dopamine in the brain. Most of these medicines help manage symptoms quite successfully.
A procedure called deep brain stimulation may also be used to treat Parkinson disease. It sends electrical impulses into the brain to help control tremors and twitching movements. Some people may need surgery to manage Parkinson disease symptoms. Surgery may involve destroying small areas of brain tissue responsible for the symptoms. However, these surgeries are rarely done since deep brain stimulation is now available.
Causes And Risk Factors
PD is idiopathic, meaning that a doctor does not know why a person has the condition. However, according to Johns Hopkins Medicine, early-onset Parkinsons disease has links to genetic inheritance from a parent.
Researchers have identified several risk factors that may make a person with Parkinsons disease more likely to experience dementia.
These risk factors include:
- advanced age at time of diagnosis
- experiencing excessive daytime sleepiness
- hallucinations before the onset of other dementia symptoms
- having a specific Parkinsons symptom that causes a person to have difficulty starting to take a step or to halt mid-step while walking
- a history of mild thought impairment
- more severe movement impairment symptoms than most people with Parkinsons disease
However, researchers do not know why some people with Parkinsons disease develop cognitive difficulties as well as movement problems.

How Can We Manage Hallucinations
It may not be necessary to treat all hallucinations of a person with PDD. Hallucinations are often harmless, and it is okay to allow them to happen, as long as they are not disruptive or upsetting to the person or surroundings. Sometimes, recognizing the hallucination and then switching the topic might be an efficient way of handling frustrations that occur because of a hallucination. If hallucinations need medical treatment, your provider may be able to discuss and suggest some options. However, many of the medications used to treat hallucinations may make movement symptoms worse.
Can Parkinsons Disease Be Prevented
Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

What Is Needed For A Parkinsons Disease Dementia Diagnosis
There is no definitive medical test that confirms cognitive decline or dementia in Parkinsons disease. The most accurate way to measure cognitive decline is through neuropsychological testing.
- The testing involves answering questions and performing tasks that have been carefully designed for this purpose. It is carried out by a specialist in this kind of testing.
- Neuropsychological testing addresses the individuals appearance, mood, anxiety level, and experience of delusions or hallucinations.
- It assesses cognitive abilities such as memory, attention, orientation to time and place, use of language, and abilities to carry out various tasks and follow instructions.
- Reasoning, abstract thinking, and problem-solving are tested.
- Neuropsychological testing gives a more accurate diagnosis of the problems and thus can help in treatment planning.
- The tests are repeated periodically to see how well treatment is working and check for new problems.
Imaging studies: Generally, brain scans such as CT scans and MRIs are of little use in diagnosing dementia in people with Parkinsons disease. Positron emission tomographic scan may help distinguish dementia from depression and similar conditions in Parkinsons disease.
Depression May Be An Early Symptom Of Parkinsons
Depression is one of the most common, and most disabling, non-motor symptoms of Parkinsons disease. As many as 50 per cent of people with Parkinsons experience the symptoms of clinical depression at some stage of the disease. Some people experience depression up to a decade or more before experiencing any motor symptoms of Parkinsons.
Clinical depression and anxiety are underdiagnosed symptoms of Parkinsons. Researchers believe that depression and anxiety in Parkinsons disease may be due to chemical and physical changes in the area of the brain that affect mood as well as movement. These changes are caused by the disease itself.
Here are some suggestions to help identify depression in Parkinsons:
- Mention changes in mood to your physician if they do not ask you about these conditions.
- Complete our Geriatric Depression Scale-15 to record your feelings so you can discuss symptoms with your doctor. Download the answer key and compare your responses.
- delusions and impulse control disorders

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.

Early Signs Of Parkinsons Disease Dementia
In the beginning, PDD can be subtle. Early on, there may be memory loss and difficulties with daily activities, says Michael S. Okun, M.D., executive director of the Norman Fixel Institute for Neurological Diseases at University of Florida Health in Gainesville. Delusions or hallucinations may also start to happen. Dr. Petrossian points out that there can be an overlap between the early signs of dementia and mild cognitive impairment due to Parkinsons disease, which can make it difficult to learn new skills and recall information or conversations.

When Pdd Progresses
In the advancing stages of Parkinsons disease dementia, legal and logistical issues may arise. For instance, family members may need to safeguard their loved ones from falls due to forgetting to use a walker and monitor their medication management. Its important for people with PDD to have their powers of attorney in place while they have the cognitive ability to do so.
Caregivers should also check their states regulations regarding dementia and driving. For instance, in California, doctors are required to notify the Department of Motor Vehicles if a person has been diagnosed with dementia, and the patient then needs to take another driving test.
What Is The Self
Protein in the diet may affect the absorption of levodopa, the major medication used to treat Parkinsons disease. Fluctuations in the level of levodopa may worsen some behavioral and cognitive symptoms. A low-protein diet may reduce fluctuations in dopamine levels. In some patients with these fluctuations, dietary changes can improve symptoms. However, it is important to ensure that the person is getting adequate calories and other nutrients.
People with Parkinsons disease should remain as active as possible. Physical therapy helps the person maintain mobility.
In general, people with Parkinsons disease plus dementia should no longer drive vehicles. Movement problems may prevent quick reactions in hazardous driving situations. Certain medications, especially those given to treat symptoms of dementia, may make them less alert. However, this should be determined on an individual basis and in compliance with the laws of the state.

Treatment Of Behavior And Mood Problems In Lewy Body Dementia
Behavioral and mood problems in people with LBD can arise from hallucinations, delusions, pain, illness, stress, or anxiety. They may also be the result of frustration, fear, or feeling overwhelmed. The person may resist care or lash out verbally or physically.
Medications are appropriate if the behavior interferes with the person’s care or the safety of the person or others. If medication is used, then the lowest possible dose for the shortest period of time is recommended.
The first step is to visit a doctor to see if a medical condition unrelated to LBD is causing the problem. Injuries, fever, urinary tract or pulmonary infections, pressure ulcers , and constipation can worsen behavioral problems and increase confusion.
Certain medications, such as anticholinergics and antihistamines may also cause behavioral problems. For example, some medications for sleep problems, pain, bladder control, and LBD-related movement symptoms can cause confusion, agitation, hallucinations, and delusions. Similarly, some anti-anxiety medicines can actually increase anxiety in people with LBD. Review your medications with your doctor to determine if any changes are needed.
Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.

What Are The Causes Of Lewy Body Dementia
The precise cause of LBD is unknown, but scientists are learning more about its biology and genetics. For example, we know that an accumulation of Lewy bodies is associated with a loss of certain neurons in the brain that produce two important chemicals that act as messengers between brain cells . One of these messengers, acetylcholine, is important for memory and learning. The other, dopamine, plays an important role in behavior, cognition, movement, motivation, sleep, and mood.
Scientists are also learning about risk factors for LBD. A risk factor is something that may increase the chance of developing a disease. Some risk factors can be controlled while others cannot. Age is considered the greatest risk factor. No specific lifestyle factor has been proven to increase one’s risk for LBD.
Other known risk factors for LBD include certain diseases and health conditions, particularly Parkinson’s disease and REM sleep behavior disorder, which have been linked to a higher risk of LBD.
Having a family member with LBD also may increase a person’s risk, though LBD is not considered a genetic disease. Variants in three genes APOE, SNCA, and GBA have been associated with an increased risk, but in most cases, the cause is unknown.
What Are The Symptoms Of Parkinsons Disease
Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:
Other symptoms include:
- Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
- Handwriting changes: You handwriting may become smaller and more difficult to read.
- Depression and anxiety.
- Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
- Pain, lack of interest , fatigue, change in weight, vision changes.
- Low blood pressure.

/4what Are The Risk Factors Of Parkinsons Disease
The various risk factors associated with Parkinson’s disease are age, genetics, gender, and heredity.
Parkinson’s disease is usually seen in people in the middle or late age. Usually people develop this condition after the age of 60 years. As per health experts, men are more likely to develop Parkinson’s disease than women. Heredity also plays an important factor in increasing the risk of developing this condition.
Another major risk factor which researchers have pointed out is the exposure to toxins. Exposure to pesticides and herbicides, which are commonly used these days, can make you more prone towards the disease.
/4symptoms Of Parkinsons Disease Seen In Feet
While walking regularly, a person’s heel touches the ground first and then the toes which thus maintains the gait, balance, posture and mobility.
But in Parkinson’s an individual’s movement gets slow. The stride length is reduced which subsequently affects the ankle due to this the person adopts a flat foot type of walk. This irregular walking style affects the foot when it strikes the ground to take a step as a result of which the individual experiences pain in foot, leg and knee.
Muscle twitching, spasms and cramps are an indicator of the onset of Parkinson’s disease.
Curled and clenched toes is also another symptom of the disorder.
Due to limited movement, the affected individual can also notice swelling in the ankle and feet which is called oedema.
Experts also throw light on foot problems seen in individuals even after Parkinson’s medication is administered to them.
Due to the medication, ankle swelling can happen as a side effect. Due to this the legs may seem heavy and these people would have difficulty in wearing shoes.
