Parkinsons Dementia Vs Alzheimers Dementia
According to experts, Parkinsons dementia can cause impaired physical activity and impacts motor skills. Two neurotransmitters called dopamine and serotonin tend to be damaged by Parkinsons.
In addition to causing issues with movement and coordination, this form of dementia can also cause a slower thought process and memory problems. This is usually less pronounced however, until the later stages of the disease.
With Alzheimers, two types of proteins in the brain, tangles and plaques , accumulate and kill brain cells. This Alzheimers-induced dementia affects memory, clear thinking, language skills, and orientation. It reduces comprehension, learning capacity, and judgement. Storing new information and memory retrieval are impacted more than motor skills.
Distinguishing between these neurodegenerative conditions is important to determine the best treatment approach. Medications for one of condition might create problems when given to a patient with the other condition.

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.
Coping With A Parkinsons Diagnosis
A diagnosis of Parkinsons can be a frightening experience for both you and your loved ones. While there is currently no cure, there are treatments available for Parkinsons symptoms and lifestyle changes you can make to slow the progression of the disease and delay the onset of more debilitating symptoms, including Parkinsons disease dementia. Early diagnosis can prolong independence and help you to live life fully for much longer.
If youve been diagnosed with Parkinsons you may feel anger, deep sadness, or fear about what the future will bring. These feelings are all normal. Its also normal to grieve as you deal with this enormous adjustment.
Give yourself some time to adjust. As with any major change in life, dont expect that you will smoothly snap into this new transition. You may feel alright for a while, and then suddenly feel stressed and overwhelmed again. Take time to adjust to this new transition.
Learn all you can about Parkinsons disease and Parkinsons disease dementia. Educating yourself and making important decisions early can help you feel more in control during this difficult time.
Reach out for support. Living with Parkinsons presents many challenges, but there is help available for this journey. The more you reach out to others and get support, the more youll be able to cope with symptoms while continuing to enrich and find meaning in your life.

What Causes Parkinsons Disease Dementia
A chemical messenger in the brain called dopamine helps control and coordinate muscle movement. Over time, Parkinsons disease destroys the nerve cells that make dopamine.
Without this chemical messenger, the nerve cells cant properly relay instructions to the body. This causes a loss of muscle function and coordination. Researchers dont know why these brain cells disappear.
Parkinsons disease also causes dramatic changes in a part of your brain that controls movement.
Those with Parkinsons disease often experience motor symptoms as a preliminary sign of the condition. Tremors are one of the most common first symptoms of Parkinsons disease.
As the disease progresses and spreads in your brain, it can affect the parts of your brain responsible for mental functions, memory, and judgment.
Over time, your brain may not be able to use these areas as efficiently as it once did. As a result, you may begin experiencing symptoms of Parkinsons disease dementia.
You have an increased risk of developing Parkinsons disease dementia if:
- youre a person with a penis
- youre older
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.

The Differences Between Alzheimer’s And Parkinson’s
16 October, 2020
Do you know the differences between Alzheimers and Parkinsons? First of all, we must say that both diseases constitute two of the causes of dementia. Now, lets be a bit more specific. According to data from the WHO , dementia due to Alzheimers disease represents 60-70% of all cases of dementia in the world.
However, its important to keep in mind that theyre very different diseases. Additionally, we must make clear that having either condition doesnt always lead to the development of dementia . In this sense, we know that between 20-60% of people with Parkinsons disease end up developing dementia.
Buter et al. conducted a study that was published in the journal Neurology. It was conducted with 233 patients with Parkinsons disease. The researchers were able to observe that about 60% of them developed Parkinsons dementia in a period of 12 years.
So whats dementia? It refers to the set of symptoms that arise as a consequence of neurological damage or disease. These symptoms involve the loss or weakening of the mental faculties and mainly affect three different areas: cognitive , behavioral , and personality .
The Effects Of Alzheimers On The Brain
Damage to the brain begins years before symptoms appear. Abnormal protein deposits form plaques and tangles in the brain of someone with Alzheimers disease. Connections between cells are lost, and they begin to die. In advanced cases, the brain shows significant shrinkage.
Its impossible to diagnose Alzheimers with complete accuracy while a person is alive. The diagnosis can only be confirmed when the brain is examined under a microscope during an autopsy. However, specialists are able to make the correct diagnosis up to
- behavioral changes
- difficulty speaking, swallowing, or walking in advanced stages of the disease
Some types of dementia will share some of these symptoms, but they include or exclude other symptoms that can help make a differential diagnosis. Lewy body dementia , for example, has many of the same later symptoms as Alzheimers. However, people with LBD but are more likely to experience initial symptoms such as visual hallucinations, difficulties with balance, and sleep disturbances.
People with dementia due to Parkinsons or Huntingtons disease are more likely to experience involuntary movement in the early stages of the disease.
Treatment for dementia will depend on the exact cause and type of dementia, but many treatments for dementia and Alzheimers will overlap.

How Exactly Is Lewy Body Dementia Related To Alzheimers Disease And Parkinsons Disease
Lewy body dementia is a broad, general term for dementia in which lewy bodies are present in the brain. Dementia with lewy bodies and Parkinsons disease dementia are two related clinical disorders that make up the general broader category of Lewy body dementia. Sometimes LBD is first diagnosed as Parkinsons disease or Alzheimers disease based on its symptoms.
- Parkinsons disease dementia : You might be diagnosed with Parkinsons disease if you start out with a movement disorder typical to Parkinsons but then have your diagnosis changed to PDD when dementia symptoms develop.
- Alzheimers disease : You might start out with memory or cognitive disorder that leads to a diagnosis of AD. Over time, other distinctive symptoms begin to appear and your diagnosis is then changed to dementia with lewy bodies. Distinctive symptoms of LBD include the changes in attention, alertness and cognitive ability changes in walking and movement visual hallucinations REM sleep behavior disorder and severe sensitivity to some antipsychotics used to treat hallucinations.
What Other Things Help
There are various ways to help a person with PDD. Speech therapy may help improve communication between people with PDD and others. Physical therapy may help strengthen and stretch stiff muscles and help to prevent falls.
Research has shown that physical exercise helps to enhance brain health and improves mood and general fitness. A balanced diet, enough sleep and limited alcohol intake are other important ways to promote good brain health. Other illnesses that affect the brain, such as diabetes, high blood pressure and high cholesterol, should also be treated if present.

Robin Was Very Aware That He Was Losing His Mind And There Was Nothing He Could Do About It
Schneider added: Robin was very aware that he was losing his mind and there was nothing he could do about it.
Jacqueline Cannon said of her fathers condition: He always used to say to me, Im losing my mind. We say to people that LBD is not just about memory. Its about the other symptoms that go with it, especially the hallucinations.
In the spotlight
Like Parkinsons disease there is currently no cure for LBD, and a need to raise awareness the case of Robin Williams will no doubt help. Dedicated research centres do already exist, such as the leading Biomedical Research Unit in Lewy Body Dementia at Newcastle University.
Professor Ian McKeith, president of the Lewy Body Society, believes there is cause for hope however. In a piece published by The Conversation, he wrote: Therapeutic trials have been few and far between in LBD because of a combination of a lack of compounds to test, a pre-occupation with targeting Alzheimers and a reluctance of regulatory bodies to recognise LBD. All of these are now changing and LBD is increasingly viewed as a malleable and commercially-viable target.
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.

How Is Lewy Body Dementia Diagnosed
There isn’t one test that can diagnose LBD. It is important to see an experienced doctor to get a diagnosis. This would usually be specialist such as a neurologist. The doctor will:
- Do a medical history, including taking a detailed account of the symptoms. The doctor will talk to both the patient and caregivers.
- Do physical and neurological exams
- Do tests to rule out other conditions that could cause similar symptoms. These could include blood tests and brain imaging tests.
- Do neuropsychological tests to evaluate memory and other cognitive functions
LBD can be hard to diagnose, because Parkinson’s disease and Alzheimer’s disease cause similar symptoms. Scientists think that Lewy body disease might be related to these diseases, or that they sometimes happen together.
It’s also important to know which type of LBD a person has, so the doctor can treat that type’s particular symptoms. It also helps the doctor understand how the disease will affect the person over time. The doctor makes a diagnosis based on when certain symptoms start:
- If cognitive symptoms start within a year of movement problems, the diagnosis is dementia with Lewy bodies
- If cognitive problems start more than a year after the movement problems, the diagnosis is Parkinson’s disease dementia
Differences Between Alzheimers And Parkinsons
Were going to group the differences between both illnesses into different blocks and explain what each of them consists of. All of them have been extracted from two reference psychopathology manuals: Belloch, Sandín, and Ramos and the DSM-5 .
The first block of differences between Alzheimers and Parkinsons refers to their type of symptoms. Lets see what they are.

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
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.

What Is Parkinsons Disease
Parkinsons disease was described by James Parkinson nearly 100 years before Dr. Alois Alzheimer described the dementia later named Alzheimers disease . Called the shaking palsy by Parkinson, PD is diagnosed when a person shows at least two of these three symptoms: slowed movements , muscle rigidity, and tremor . We recognize many other associated signs of PD, including expressionless face, quiet speech, cramped handwriting, shuffling gait, trouble getting out of a chair, and difficulty swallowing. Many of the symptoms of idiopathic Parkinson’s disease result when certain nerve cells that produce dopamine in the brain begin to malfunction and die.
Most cases are called idiopathic, meaning the cause remains unknown, although a small number of cases are linked with poisoning , head trauma, more complex PD-like neurological disorders , or reversible toxic medication effects ,
Alzheimers Vs Parkinson’s Disease Dementia
The dementia of Parkinsons disease has some similarities to the dementia of Alzheimers disease. And there are some differences, too. Alzheimers disease causes dementia slowly over time, while the dementia of Parkinsons disease often develops more quickly and dramatically.
The symptoms of Parkinsons dementia can come and go from day to day, while the symptoms of Alzheimers dementia will not go away.

Symptoms Related To Brain Function Are Different
There is some overlap, but in general, the overall cognitive symptoms that people experience with Parkinsons disease dementia and Alzheimers are different. Alzheimers mainly affects language and memory at the outset, whereas Parkinsons affects problem-solving, speed of thinking, memory, and mood.6
Unlike in Alzheimers disease, people with Parkinsons-related dementia often experience hallucinations, delusions, and paranoid thoughts. Both conditions can lead to depression, anxiety, and sleep disturbances.4,6
Lewy Body Dementia Vs Parkinsons Disease Dementia
Diagnoses of Lewy body dementia include dementia with Lewy bodies and Parkinsons disease dementia. Symptoms in both of these diagnoses can be similar.
Lewy body dementia is a progressive dementia caused by abnormal deposits of a protein called alpha-synuclein in the brain. Lewy bodies are also seen in Parkinsons disease.
The overlap in symptoms between Lewy body dementia and Parkinsons disease dementia include movement symptoms, rigid muscles, and problems with thinking and reasoning.
This seems to indicate that they could be linked to the same abnormalities, though more research is needed to confirm that.
The later stages of Parkinsons disease have more severe symptoms that may require help moving around, around-the-clock care, or a wheelchair. Quality of life can decline rapidly.
Risks of infection, incontinence, pneumonia, falls, insomnia, and choking increase.
Hospice care, memory care, home health aides, social workers, and support counselors can be a help in later stages.
Parkinsons disease itself isnt fatal, but complications can be.

Number Of People Affected
Parkinsons disease is thought to affect about 2 percent of Americans over 65. Of those, about 50 to 80 percent will go on to develop Parkinsons-related dementia.1 The Parkinsons Foundation estimates that nearly 1 million Americans will be living with Parkinsons by 2020. The disease affects 1.5 times more men than women.7
Approximately 5.8 million Americans are currently living with Alzheimers disease. That number is expected to increase to 14 million by 2050.8 There is little difference between numbers of men and women who develop Alzheimers, but there are more women with the disease, because women tend to live longer than men.3
Coping With Dietary Problems
Many people with Parkinsons experience various eating and dietary problems, such as constipation, chewing and swallowing difficulties, and upset stomach. The following tips can help you minimize the symptoms.
If you suffer from constipation Drink lots of water and eat fiber-rich foods, including beans, brown rice, whole grains, and fruit.
If you have trouble chewing or swallowing food Cut foods into smaller portions to avoid choking and to encourage digestion, and remain upright for 30 minutes after eating.
If youre struggling with fatigueLimit the amount of sugar youre eating. Also avoid alcohol and caffeine, especially before bed, as they can reduce the quality of your sleep.
If you take levodopa Dont eat meat or other protein-rich foods for at least 30-60 minutes after taking levodopa, as protein blocks your bodys ability to absorb the medication.
If your medication gives you an upset stomach Take your medication with a full glass of water and a small non-protein based snack, such as a piece of toast or fruit.
Some Parkinsons disease medications need to be taken promptly at specified times before or after eating, so it can also help to establish a regular routine for meal and medication times.
