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.
Dysfunction In The Fronto
Volitional shifts of attention are thought to depend on top-down signals within a fronto-parietal network comprising prefrontal cortical areas and posterior parietal cortices , wherein prefrontal regions modulate activity in the network according to task demands .
The major cortical neural networks affected in PDD. Areas of cortical atrophy associated with visuospatial and visuoperceptual deficits in PDD are based on the data presented in . Areas of cortical atrophy specifically associated with the presence of visual hallucinations in PDD are based on the data presented in . Functional cortical regions comprising the fronto-parietal attention network are based on the data presented in . Cortical regions are identified according to the Allen Brain Atlas for the human brain, and manually drawn onto the corresponding 3D brain image. In this representation the same cortical regions are affected symmetrically in both hemispheres, however in the original studies above the extent of atrophy in these regions was not symmetrical between hemispheres, and varied between individual patients. In the inferior view of the cortex the cerebellum has been removed to expose the fusiform gyri more clearly. DLPFC = dorsolateral prefrontal cortex PPC = posterior parietal cortex VLPFC = ventrolateral prefrontal cortex.
Degeneration In The Mesocortical Dopamine Network Contributes To Executive Dysfunction
However, dopamine-dependent neural circuitry underlying executive deficits in Parkinsons disease may not be limited to the fronto-striatal network alone. The mesocortical dopamine network originates in the midbrain ventral tegmental area and projects diffusely to neocortical areas, particularly prefrontal, insular and cingulate cortices . Release of dopamine from this network modulates prefrontal D2 receptors and thereby facilitates cognitive flexibility, a core feature of executive processing . Insular cortex in particular is considered to mediate such flexibility, acting as a hub to recruit other cognitive circuits such as the fronto-parietal network . In support of this, insular lesions in human patients have been shown to impair performance on tasks requiring cognitive flexibility .

Diagnosis: Parkinson’s Dementia Or Dementia With Lewy Bodies
During assessment, a specialist may look at when the dementia symptoms first appeared before reaching a diagnosis of Parkinson’s dementia or dementia with Lewy bodies.
If there have been motor symptoms for at least one year before dementia symptoms occur, specialists will often give a diagnosis of Parkinson’s dementia.
If dementia symptoms occur before or at the same time as motor symptoms, specialists will usually give a diagnosis of dementia with Lewy bodies.
However, it should be noted that in some cases of dementia with Lewy bodies, no motor symptoms develop at all.
Theres no single test – diagnosis is made through several different assessments, usually starting with an appointment with your GP or Parkinson’s nurse.
Some people find it helps to go to the appointment with someone who knows them well, who can give the GP or Parkinson’s nurse information about changes they’ve noticed.
Your GP can discuss your symptoms with you and carry out a physical examination, including blood and urine tests, to rule out other potential causes of the symptoms .
Your GP may also review your medication, in case your symptoms are side effects.
If your GP thinks you have dementia, they can refer you to a specialist, such as a neurologist, psychiatrist or geriatrician.
You might be referred to a memory clinic or memory service. In some areas of the country, you can refer yourself to these services.
But if you feel you need to see the specialist again, you can ask to be referred back.
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.

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.
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

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 Pathologies Are Different But Many Of The Symptoms Can Be Similar
We do know that the pathology is quite different between Parkinsons and dementia, said Dr. Odinachi Oguh, a neurologist at the Cleveland Clinic Lou Ruvo Center for Brain Health. But the processes in which memory is impacted in both diseases is about the same.
From the pathology standpoint, both diseases are characterized by a neurodegenerative process, Oguh said. The neurodegeneration results in abnormal accumulation of protein, which builds up and becomes toxic to the brain.
Alzheimers, for example, affects memory areas of the brain, which include the temporal lobes, as well as the memory center, or hippocampus. Parkinsons, meanwhile, starts in the basal ganglia part of the brain, and as the disease progresses, it can also affect the memory center, resulting in forgetfulness, an early sign of Alzheimers or other forms of dementia.

What Causes Parkinson Disease
Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.
Parkinsons Disease: Symptoms Stages And Treatment
Parkinson’s disease usually begins after age 60, gradually progressing over the years. Some people can have early-onset Parkinson’s disease, starting in their 30s or 40s. It is primarily a movement disorder characterized by resting tremors and slowness and stiffness of movement.
In the late stages of the disease, Parkinson’s dementia can develop. But most people who have Parkinson’s disease do not develop dementia as a part of the condition.

Can You Have Both Parkinsons And Alzheimers
People who already have Parkinsons disease and later develop signs of dementia are diagnosed with Parkinsons dementia.6 However, if you first have Alzheimers disease and develop signs of movement difficulties, you can also have a diagnosis of Parkinsons disease.

Parkinson’s Signs Linked To Alzheimer’s
Parkinson’s-like Symptoms Tied to Risk of Alzheimer’s Disease
April 22, 2003 — Older adults who rapidly develop the tremors and other classical symptoms of Parkinson’s disease may be up to eight times as likely to develop Alzheimer’s disease. A new study shows that the progression of symptoms traditionally associated with Parkinson’s disease, such as an irregular gait, muscle rigidity, tremors, and limited movement, are also linked to a decline in mental functioning and the development of Alzheimer’s disease.
Researchers say Parkinson’s disease-like symptoms are common in older people with and without Alzheimer’s disease, but the link between the progression or severity of these muscle-related symptoms and later development of Alzheimer’s disease has not been studied until now.
Their study, published in the April issue of The Archives of Neurology, tracked the progression of symptoms associated with Parkinson’s disease among 824 Catholic clergy members with an average age of 75 who had no signs of Alzheimer’s or Parkinson’s disease at the start of the study.
Researcher Robert Wilson, PhD, of Rush-Presbyterian-St. Luke’s Medical Center in Chicago, and colleagues, say the rate of progression of symptoms, especially worsening gait and rigidity, was also linked to scores on tests that measured mental function. As the person’s physical symptoms worsened, his or her mental functioning also declined, and more rapid physical decline was associated with more rapid mental decline.

Management Of Parkinsons Disease Dementia
The relative importance of cholinergic network dysfunction in PDD is reflected in current treatment strategies, which focus on the use of AChEIs, such as rivastigmine, donepezil and galantamine, to boost cholinergic function. Two large placebo-controlled trials have shown that rivastigmine significantly improves deficits in orienting of attention, vigilance and cognitive fluctuation in patients with PDD , and indeed patients with more severe attentional deficits appear to respond best . These results serve to reinforce the cholinergic basis of attention deficits in PDD according to the neural network model. Benefits from AChEIs have also been demonstrated for executive deficits visuospatial tasks and hallucinations . Whether these improvements are due to amelioration of the cholinergic network deficits underlying these cognitive processes, or are secondary to an overall improvement in attention assisting other overlapping cognitive functions, or a combination of both, is unknown.
See A Doctor If Youre Noticing Symptoms Beyond Parkinsons
Sometimes the mood or memory changes a person experiences cannot entirely be explained just by Parkinsons. If this is the case, the caregiver should explore other diagnoses, because if something cannot be explained by Parkinsons, theres certainly a risk of it being dementia, Oguh said.
She added that some signs to look for include increased memory and behavioral problems, like mood swings, anxiety or depression. Psychiatric behaviors, like hallucinations, delusions or paranoia, cannot just be explained by Parkinsons, and are more likely to be caused by a form of dementia like Lewy body dementia.
Oguh urged caregivers to be aware of changing symptoms like these.
I think sometimes family members are able to realize sooner than the patient, Oguh said. Often the patient might lack insight as to what is happening. I would encourage family members to seek expert opinion and treatment options.

Is The Dementia Caused By Parkinsons Or Something Else
Indications that dementia may be caused by something other than Parkinsons disease include agitation, delusions , and language difficulties. If the onset of cognitive symptoms is sudden, theyre more likely due to something other than Parkinsons diseaseeven reversible causes such as infection, a vitamin B12 deficiency, or an underactive thyroid gland.
Depression can mimic dementia by causing similar symptoms such as apathy, memory problems, and concentration difficulties. Since depression is very common in Parkinsons patients, its important to recognize the signs and symptoms of depression in older adults.
Parkinsons disease dementia vs. other dementias
Other types of dementia that can be commonly mistaken for Parkinsons disease dementia include:
Lewy Body Dementia is characterized by fluctuations in alertness and attention, recurrent visual hallucinations, and Parkinsonian motor symptoms like rigidity and the loss of spontaneous movement. In this disorder, cognitive problems such as hallucinations tend to occur much earlier in the course of the disease and often precede difficulties with walking and motor control.
Alzheimers disease and Parkinsons disease are both common in the elderly, especially in those over 85. Patients with Parkinsons who develop dementia may even develop Alzheimers dementia as well. Therefore, its important to be aware of the signs of Alzheimers Disease and how its treated.
Early Signs And Symptoms Are Different
Parkinsons disease generally begins as a movement disorder. Early signs and symptoms include:2
- Tremor, which often begins in the hand or fingers
- Slowed movement, which may include foot dragging
- Slowed automatic movements such as blinking, smiling, and swinging your arms when you walk
Alzheimers disease generally begins as noticeable memory loss. Early signs and symptoms include:3,4
- Trouble remembering familiar words
- Challenges performing everyday tasks such as balancing a checkbook

Coping With Alzheimers And Parkinsons Disease
Living with both Alzheimers disease and Parkinsons disease is extremely challenging. The dementia of Alzheimers combined with the movement effects of Parkinsons can make self-care especially difficult.
Rivastigmine is the only medication that is specifically approved for the treatment of Parkinsons dementia. Additionally, you may need medication for the motor symptoms of Parkinsons disease and medication to help with other symptoms, such as dry skin.
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.

What Are The Complications Of Parkinson Disease
Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.
Parkinson disease dementia can cause problems with:
- Speaking and communicating with others
- Problem solving
- Paying attention
If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.
Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.
How Are Parkinsons And Dementia Related
Parkinsons and dementia are two of the most common degenerative neurological conditions in this country, affecting many thousands of people. However, there are a lot of myths and misunderstandings about the illnesses.
If you have been told that you have either condition, the future may seem bleak and bewildering. Whether youve found this blog having been recently been diagnosed, or are worried about a loved one, then read on, hopefully, we can help you to gain some understanding.

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.
What Causes Lewy Body Dementia
The causes of LBD are not yet well understood, but research is ongoing in this area. There are probably multiple factors involved, including genetic and environmental risk factors that combine with natural aging processes to make someone susceptible to LBD.

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.
