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.
How Is Parkinson Disease Diagnosed
Parkinson disease can be hard to diagnose. No single test can identify it. Parkinson can be easily mistaken for another health condition. A healthcare provider will usually take a medical history, including a family history to find out if anyone else in your family has Parkinson’s disease. He or she will also do a neurological exam. Sometimes, an MRI or CT scan, or some other imaging scan of the brain can identify other problems or rule out other diseases.
What Are The Parkinsons Disease Dementia Criteria
Many people with Parkinsons disease experience cognitive changes , but not all of them develop full-blown dementia. So at what point does Parkinsons disease cause dementia?
On average, Parkinsons disease dementia happens about 10 years after a person first starts having movement problems.
It happens many, many years after someone has developed Parkinsons,Lynda Nwabuobi, MD, assistant professor of clinical neurology at Weill Cornell Parkinsons Disease and Movement Disorders Institute, tells Health. It can be around 10 to 15 years.
In fact, if someone shows signs of dementia early on in their Parkinsons diagnosis , it could be that they were misdiagnosed out of the gate. They might have dementia with Lewy bodies, Dr. Nwabuobi explains.
Timing is the main factor in Lewy body dementia versus Parkinsons disease dementia. While the two can look very similar, the dementia symptoms occur before motor symptoms in Lewy body dementia, and in Parkinsons disease the reverse is true.
If you look at the brain, its difficult to distinguish them, Dr. Litvan says. But clinically, they are different.

What Are The Parkinson’s Disease Dementia Criteria
Many people with Parkinson’s disease experience cognitive changes , but not all of them develop full-blown dementia. So at what point does Parkinson’s disease cause dementia?
On average, Parkinson’s disease dementia happens about 10 years after a person first starts having movement problems.
“It happens many, many years after someone has developed Parkinson’s,”Lynda Nwabuobi, MD, assistant professor of clinical neurology at Weill Cornell Parkinson’s Disease and Movement Disorders Institute, tells Health. “It can be around 10 to 15 years.”

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.
Antidepressants can be used to treat depression and anxiety, which are common in LBD. Many of them are often well tolerated by people with LBD.

Associated Clinical Features Of Probable Pdd
Associated clinical features are defined along four primary cognitive domains and a spectrum of behavioural disorders . The MDS Task Force recommended a number of tests from which the clinician could choose to assess the four primary cognitive domains and suggested that the four-item Neuropsychiatric Inventory, which covers hallucinations, depression, delusions and apathy, might be useful in assessing behavioural symptoms associated with PDD . A diagnosis of probable PDD is made on the basis of a typical profile of cognitive deficits . If dementia exists in the presence of established PD, yet the associated clinical features are not considered typical , only possible PDD should be diagnosed.
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.

Efns Task Force Recommendations
A joint task force of the EFNS and the European section of the MDS provided their recommendations for the therapeutic management of PD in 2006, including a section devoted to the management of non-motor problems in PD, such as dementia . Although they acknowledged that cognitive improvements in patients with PDD treated with cholinesterase inhibitors were modest, they classified clinical evidence with rivastigmine and donepezil as class I and II studies respectively. For overall management, they recommended both discontinuation of medications that might impair cognition and the addition of cholinesterase inhibitor therapy either with rivastigmine or with donepezil . Additionally, the authors recommended that the addition of cholinesterase inhibitor therapy with rivastigmine or donepezil may also help in the treatment of psychosis in this population .
Diagnosis Of Parkinsons Disease Dementia
Diagnosis of PDD typically requires the initial diagnosis of PD, with the signs of Parkinsons disease of rest tremor, bradykinesia , rigidity , and postural instability.
At Pacific Movement Disorders Center we regularly monitor patients for cognitive changes which could signal the beginning of dementia, utilizing evidence-based screening tests. If concern arises, detailed neuropsychological evaluation with clear delineation of cognitive strengths and weakness can be obtained. On occasion, volumetric MRI scanning or PET scanning may play a role.
Differentiating between PDD and Dementia with Lewy Bodies can be challenging, given both conditions pertain to dementia and parkinsonism .
Lewy Bodies in PD patients predominate in the deep part of the brain called the substantia nigra, whereas in DLB they are widespread from onset.
The main differentiating factor is the clinical history:
In PDD, parkinsonism comes first, typically years prior to onset of dementia, whereas in DLB, cognitive changes either precede or coincide with onset of parkinsonism.In PDD, there tends to be clear improvement with levodopa for the motor symptoms at least.
For more on differentiating between PDD and DLB, see this comparison table.

What Happens In Pdd
People with PDD may have trouble focusing, remembering things or making sound judgments. They may develop depression, anxiety or irritability. They may also hallucinate and see people, objects or animals that are not there. Sleep disturbances are common in PDD and can include difficulties with sleep/wake cycle or REM behavior disorder, which involves acting out dreams.
PDD is a disease that changes with time. A person with PDD can live many years with the disease. Research suggests that a person with PDD may live an average of 57 years with the disease, although this can vary from person to person.
Behaviors Seen In Parkinsons Disease Dementia
As dementia progresses, managing disorientation, confusion, agitation, and impulsivity can be a key component of care.
Some patients experience hallucinations or delusions as a complication of Parkinsons disease. These may be frightening and debilitating. Approximately 50 percent of those with the disease may experience them.
The best thing to do when giving care to someone experiencing hallucinations or delusions from Parkinsons disease dementia is to keep them calm and reduce their stress.
Take note of their symptoms and what they were doing before they exhibited signs of hallucinating and then let their doctor know.
This element of the disease can be particularly challenging for caregivers. Patients may become unable to care for themselves or be left alone.
Some ways to make caregiving easier include:
- sticking to a normal routine whenever possible
- being extra comforting after any medical procedures
- limiting distractions
- using curtains, nightlights, and clocks to help stick to a regular sleep schedule
- remembering that the behaviors are a factor of the disease and not the person

Ways To Decrease The Risk Of Parkinsons And Alzheimers
There is currently no cure for either disease. Parkinsons is considered a more treatable condition, however, especially in the early stages of the disease. Treatments include medication, physical therapy, and lifestyle modifications such as dietary changes. Research continues to suggest that a brain-healthy lifestyle can help prevent both Alzheimers and Parkinson’s. Here are some basic guidelines:
What Is The Self
Protein in the diet may affect the absorption of levodopa, the major medication used to treat Parkinson’s 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 Parkinson’s disease should remain as active as possible. Physical therapy helps the person maintain mobility.
In general, people with Parkinson’s 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.

Is There A Test To Diagnose Pd Dementia
There is no single test for PDD. The diagnosis is made clinically. If you or someone you spend time with notices cognitive changes, it is important to discuss them with your care team. If you dont have a care team in place, its important to find a specialist or physician familiar with dementia or geriatric medicine. Call the Parkinson’s Foundation Helpline 1-800-4PD-INFO for a referral.
Key Brain Changes Are Different
The key brain changes linked to Parkinsons disease and Parkinsons-related dementia are abnormal deposits of common brain proteins, called alpha-synuclein. These deposits are known as Lewy bodies, named after the doctor who discovered them. As more of these proteins clump in the brain, normal brain cells begin to die off.1
In Alzheimers disease, the key brain changes include the buildup of different brain proteins, called amyloid and tau. When amyloid proteins clump together, they form abnormal structures known as plaques. Abnormal groups of tau proteins form tangles.3 Over time, the buildup of these proteins causes normal brain cells to die, and affected parts of the brain may shrink.5

Comparing Trajectories And Conceptualization Of Palliative Care For Dementia And Pd
The two disease trajectories may overlap partly as dementia is a frequent manifestation of PD. Mild cognitive impairment may already present upon diagnosis of PD . Importantly, it is independently associated with lower quality of life . Across studies, typically about a quarter of patients with PD have dementia , but ultimately, most develop dementia .
A clear conceptualization of palliative care in chronic-progressive diseases is important for the development of healthcare systems that facilitate the integration of a palliative approach . Therefore, in this article we compare the disease trajectories of dementia and PD in as far as relevant for the conceptualizations of palliative care. We do not include atypical Parkinsonian disorders such as multiple system atrophy because these warrant a special approach with earlier palliative care . We first provide background on where we are by describing how palliative care for dementia and PD developed.
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 Are The Signs And Symptoms Of Parkinson’s Disease Dementia
Parkinson’s disease dementia can’t be diagnosed conclusively by a single test. Instead, doctors may use multiple tests and consider a range of Parkinson’s disease dementia criteria, including symptoms like:
- Feelings of disorientation or confusion
- Agitation or irritability

Parkinson’s Disease Dementia And Dementia With Lewy Bodies
The key pathological hallmark found in brains of Parkinson’s disease and Parkinson’s disease dementia patients are abnormal microscopic deposits composed of alpha-synuclein. This protein is found widely in the brain but its normal function is not yet well understood. The deposits are called “Lewy bodies”. Lewy bodies are also found in several other neurodegenerative brain disorders, including dementia with Lewy bodies . Evidence suggests that Parkinson’s disease and Parkinson’s disease dementia, and dementia with Lewy bodies, may be linked to the same underlying abnormalities in brain processing of alpha-synuclein.

Parkinson’s Disease With Dementia
Parkinsons dementia is a condition that some people can experience as Parkinsons disease progresses. It affects thinking and memory and can have a big impact on different aspects of life.
Everyone experiences Parkinsons dementia in different ways. Symptoms can include:
- Memory and concentration problems
- Struggling to find the right word and names
- Problems with decision making, planning activities or solving problems
- Everyday activities such a dressing, cooking and shopping
- Changes in appetite, energy levels and sleeping patterns.
- Depression and anxiety. Some people may find it difficult to control their emotions.
What Are The Symptoms Of These Diseases
The main symptoms of Parkinson’s disease involve motor control, such as tremor , slowness of movement, stiffness of the limbs and trunk as well as postural instability. Many patients develop a decline in thinking and reasoning known as Parkinsons disease dementia if it occurs more than one year after the initial diagnosis of Parkinsons disease. Common symptoms for PDD include decline in memory, concentration and judgment, visual hallucinations, depression, irritability and anxiety.
The central feature of Lewy body dementia is progressive cognitive decline, combined with pronounced fluctuations in alertness and attention, complex visual hallucinations and motor symptoms such as rigidity and the loss of spontaneous movement. It can easily be mistaken for Alzheimers disease or for Parkinsons disease dementia .

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.
