How To Stay Sharp
Several studies aimed at identifying various subtypes of Parkinson’s disease are underway. These projects including the Parkinson’s Outcomes Projects, the Parkinson’s Progression Markers Initiative and the Alzheimer’s Disease Neuroimaging Initiative might one day yield information that could help doctors flag patients at greatest risk of specific complications, including dementia, earlier in the disease process. In the meantime, there are steps you can take to lower the risk of memory problems or catch them as soon as possible.
Preventive strategies are largely aimed at broadly promoting good brain health. Regular exercise is important, and even people who’ve developed substantial motor problems can find classes or activities that work for their level or are specifically for people with Parkinson’s. Dolhun says that maintaining strong social ties and eating a healthy, balanced diet such as the Mediterranean, with its emphasis on anti-inflammatory fatty fish, whole foods and plenty of antioxidant-rich fruits and vegetables are essential, too.
Crossword puzzles are fine, as is mixing things up, Okun says. Do something with your left hand if you’re right-handed, he says. He also encourages patients to listen to audiobooks with a partner or caregiver, stopping after each chapter and having a discussion to ensure that both parties can reiterate what happened .

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.

How Is Parkinsons Disease Dementia Different From Alzheimers Disease
Parkinsons disease Dementia must not be confused with Alzheimers disease. Dementia is a hallmark feature of Alzheimers whereas a patient may not necessarily contract Dementia if he happens to contract Parkinsons. Having mentioned that, Dementia does have a greater social and occupational impact on the functioning of people when it affects someone with Parkinsons as compared to Alzheimers.
This is due to the combination of motor and cognitive impairments. Parkinsons directly affects problem-solving functions in a person, besides other aspects such as the speed of thinking, memory, and mood. Parkinsons Dementia Aggression can also be related to Lewy bodies, where sticky clumps of protein are found in the nerve cells of people diagnosed with Parkinsons.
Finally, it must be known to all those associated with Parkinsons in any capacity, whether be it a patient or a caregiver, that majority of people with Parkinsons may experience some of the other forms of cognitive impairment over time. Though cases vary from person to person, the development of Dementia in those diagnosed with Parkinsons cannot be predicted. To put it in numbers, 30 percent of people with Parkinsons never develop dementia as a part of their progression.

What Is Aggressive Parkinsons Disease
As written above, Parkinsons dementia aggression is that form of Parkinsons which makes the patient exhibit aggressive behavior. They vent out their aggression either verbally or physically, in the various forms that have been written above. Besides verbal and physical outbursts, PD Dementia patients are also prone to hallucinating caused by the medication administered. Hallucinations in PD Dementia patients primarily occur because of the effects of dopaminergic agents for motor symptoms.
Loss of dopamine neurons in the ventral tegmental area is one of the likeliest of all neuropathological causes as changes in serotonin and norepinephrine systems are not. For the uninitiated, the ventral tegmental area is the origin of the mesolimbic dopaminergic projection. Plenty of studies have gone into analyzing the cause behind the aggression in PD Dementia patients. Depression in PD Dementia patients has been identified due to changes in the medial frontal cortex and the anterior cingulate. Akinetic-rigid variants have been found in patients showing signs of major depression.
What Causes Parkinson Disease And Alzheimer
Parkinsons dementia is caused by impaired physical activity in which dopamine and serotonin are damaged by the disease.
On the other hand, in Alzheimers disease, two types of brain proteins store and kill plaque brain cells that are intertwined.
In addition, the disease impairs learning, comprehension, and judgment.

Theres A Spectrum Of Pathologies
Scientists have been examining this linkand how the two diseases often overlapfor some time, but still arent completely certain how they contribute to one another. As a result, physicians sometimes group the diseases into different combinations when making diagnoses.
Dementia in Parkinsons patients can present itself in varying forms. In some cases, the Parkinsons pathology can trigger the dementia pathologya situation that results in whats known as Parkinsons disease dementia, says Dr. Aaron Ritter, Director of the Clinical Research Program at the Cleveland Clinic Lou Ruvo Center for Brain Health.
A substantial subset of folks with Parkinsons who live long enough, will develop dementia, Ritter said.Its separate from Alzheimers, but its likely related to Parkinsons pathology, a sort of spreading of Parkinsons.
In other cases, patients may develop a form of dementia like Alzheimers separately from their Parkinsons disease, though this isnt visible until after death, through an autopsy.
Many people with Parkinsons may also develop Lewy body dementia shortly after their diagnosis. When you have Parkinsons, and see cognitive declineor things like hallucinations and delusionsup to a year after your Parkinsons diagnosis, you may have Lewy body dementia, Oguh said.
Treatments For Parkinsons Disease Dementia And Dementia With Lewy Bodies
Treatments for DLB are similar to PDD and are aimed at symptom control. The motor symptoms of slowness, stiffness and walking difficulties can be treated with Levodopa. However, Levodopa can cause or exacerbate hallucinations, making it difficult to use it as a treatment for patients who have or are at risk of having hallucinations. Sometimes, clinicians will need to treat the hallucinations more aggressively in order for a patient to tolerate Levodopa given to help the motor symptoms. On the flipside, anti-psychotic medications to control hallucinations can worsen motor symptoms, so treating all the symptoms of LBD simultaneously can be a tricky balancing act.

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
Treating Parkinsons Disease Dementia
A treatment plan for PDD typically includes medications that boost the brains level of certain neurotransmitters and help improve memory and processing speed, Dr. Petrossian says. Exercise is also an important part of the treatment planDr. Petrossian recommends skill-based activities like boxing or dance to boost cognitive function as well as fitness. PDD symptoms should be monitored long-term by a neurologist, and in some cases a psychiatrist, says Dr. Okun. In many cases, physical, occupational, speech, and social work therapy can also be useful since PPD affects all aspects of life.

What Is Parkinsons Disease Dementia
Parkinsons disease dementia is a brain disorder that occurs in somebut not allpeople living with Parkinsons disease. The brain cell damage caused by the disease can lead to a loss of memory and other cognitive functions such as problem solving and speed of thinking. These changes in thinking and behavior can impact your daily living, independence, and relationships.
In those who do develop Parkinsons disease dementia, there is at least one yearand usually 10 to 15 yearsbetween the Parkinsons diagnosis and the onset of dementia. According to estimates by the Alzheimers Association, 50% or more of people with Parkinsons disease eventually experience dementia, although there are a number of risk factors that impact the likelihood of developing symptoms:
- Parkinsons patients who experience hallucinations, excessive daytime sleepiness, and more severe motor control problems are at higher risk for dementia.
- Dementia is more common in people who are older at onset of Parkinsons.
- Dementia is a bigger risk factor in non-tremor predominant Parkinsons.
- Overwhelming stress, cardiovascular disease, and adverse reactions to the Parkinsons disease drug levodopa can also indicate an increased risk for developing dementia.
- Dementia is relatively rare in people who develop Parkinsons before age 50, no matter how long they have had the disease.

What Are The Treatments For Lewy Body Dementia
There is no cure for LBD, but treatments can help with the symptoms:
- Medicines may help with some of the cognitive, movement, and psychiatric symptoms
- Physical therapy can help with movement problems
- Occupational therapy may help find ways to more easily do everyday activities
- Speech therapy may help with swallowing difficulties and trouble speaking loudly and clearly
- Mental health counseling can help people with LBD and their families learn how to manage difficult emotions and behaviors. It can also help them plan for the future.
- Music or art therapy may reduce anxiety and improve well-being
Support groups can also be helpful for people with LBD and their caregivers. Support groups can give emotional and social support. They are also a place where people can share tips about how to deal with day-to-day challenges.

What Causes Parkinson’s Disease Dementia
Doctors don’t yet know the exact cause of Parkinson’s disease dementia, but they think it has to do with an accumulation of a protein called alpha-synuclein. When it builds up in the brain, it can create clumps called “Lewy bodies” in nerve cells, causing them to die.
The death of those cells usually results in the motor symptoms typically associated with Parkinson’s disease. As Parkinson’s disease progresses, those Lewy bodies may eventually damage the brain and cause problems with memory and thinking.
While many people with Parkinson’s disease experience cognitive changes, not all of them will go on to develop dementia. It’s estimated that between 50% and 80% of individuals with the disease eventually develop Parkinson’s disease dementia, usually in the later stages of the disease.

Signs And Symptoms Of Pdd
Common signs and symptoms of Parkinsons disease dementia include:
- Poor memory and concentration
- Depression
- Visual hallucinations
If youve noticed some of the above signs and symptoms in yourself or a loved one, its important to get them checked out. But dont jump to conclusions. People with Parkinsons often experience cognitive changes such as anxiety, lack of motivation, and slowed thinking. These symptoms do not automatically mean dementia.
Difference Between Parkinsons Disease Dementia And Dementia With Lewy Bodies
Technically, the difference between these two conditions lies in how quickly the cognitive difficulties and hallucinations develop in relation to the movement issues. In DLB, the cognitive difficulties and hallucinations develop much sooner in the disease course than in PDD, sometimes even prior to the movement difficulties. Because of the similarities between PD, PDD, and DLB, current thinking in the medical community is that they should be viewed as related diseases which fall along a continuum of Lewy body disorders.

Parkinsons Doesnt Always Cause Dementia
While cognitive decline is common in both Alzheimers and Parkinsons, it is less likely to occur in Parkinsons patients. According to studies, only half of those with Parkinsons develop cognitive difficulties. This can range from mild forgetfulness to full-blown dementia.
When dementia does manifest itself with Parkinson, it occurs in the subcortical area of the brain. Alzheimers dementia occurs in the cortical area of the brain. As a result of this, the clinical symptoms of these two dementias can be somewhat different.
Whats The Difference Between Lewy Body Dementia Parkinsons Disease And Alzheimers Disease
Lewy body dementia is an umbrella term for two related clinical diagnoses: dementia with Lewy bodies and Parkinsons disease dementia. These disorders share the same underlying changes in the brain and very similar symptoms, but the symptoms appear in a different order depending on where the Lewy bodies first form.
Dementia with Lewy bodies is a type of dementia that causes problems with memory and thinking abilities that are severe enough to interfere with everyday activities. It specifically affects a persons ability to plan and solve problems, called executive function, and their ability to understand visual information. Dementia always appears first in DLB. The motor symptoms of Parkinsons such as tremor, slowness, stiffness and walking/balance/gait problems usually become more evident as the disease progresses. Visual hallucinations, REM sleep behavior disorder, fluctuating levels of alertness and attention, mood changes and autonomic dysfunction are also characteristic of DLB.
Finally, Alzheimers is characterized by different abnormal clumps called amyloid plaques, and jumbled fiber bundles called tau tangles. These microscopic structural changes in the brain were discovered by Dr. Alois Alzheimer in 1906. These plaques and tangles, together with loss of connections between nerve cells, contribute to loss of coherence and memory, as well as a progressive impairment in conducting normal activities of daily living.

Can Parkinsons Disease Make You Aggressive
Parkinsons disease Dementia or PD Dementia can make a patient very aggressive. Parkinsons Dementia Aggression germinating from Parkinsons disease Dementia can lead patients to behave erratically, experience sudden anger outbursts, feel constantly irritated, and always be in a state of restlessness. Outbursts are generally in the form of:
- Shouting
- Falling
How Is Age Related To Pdd
Both PD and PDD are more common with increasing age. Most people with PD start having movement symptoms between ages 50 and 85, although some people have shown signs earlier. Up to 80% of people with PD eventually develop dementia. The average time from onset of movement problems to the development of dementia is about 10 years.

What Is Needed For A Parkinson’s Disease Dementia Diagnosis
There is no definitive medical test that confirms cognitive decline or dementia in Parkinson’s 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 individual’s 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 Parkinson’s disease. Positron emission tomographic scan may help distinguish dementia from depression and similar conditions in Parkinson’s disease.
What Are The Symptoms Of Lewy Body Dementia
LBD is a progressive disease. This means that the symptoms start slowly and get worse over time. The most common symptoms include changes in cognition, movement, sleep, and behavior:
- Dementia, which is a loss of mental functions that is severe enough to affect your daily life and activities
- Changes in concentration, attention, alertness, and wakefulness. These changes usually happen from day to day. But sometimes they can also happen throughout the same day.
- Visual hallucinations, which means seeing things that are not there
- Problems with movement and posture, including slowness of movement, difficulty walking, and muscle stiffness. These are called parkinsonian motor symptoms.
- REM sleep behavior disorder, a condition in which a person seems to act out dreams. It may include vivid dreaming, talking in one’s sleep, violent movements, or falling out of bed. This may be the earliest symptom of LBD in some people. It can appear several years before any other LBD symptoms.
- Changes in behavior and mood, such as depression, anxiety, and apathy
In the early stages of LBD, symptoms can be mild, and people can function fairly normally. As the disease gets worse, people with LBD need more help due to problems with thinking and movement. In the later stages of the disease, they often cannot care for themselves.
