How The Brain Progresses With Pd
In this one-hour webinar movement disorder specialist Yasar Torres-Yaghi shared how the pathology of Parkinson’s disease begins in the gut before progressing to the brain. As the pathology expands throughout the brain it affects more neurotransnitters than just dopamine causing both motor and non-motor symptoms. Dr. Torres-Yaghi shares a widely used cognitive evaluation tool before answering questions about communicating well with your neurologist and advocating for the care you need.
Does Parkinson’s Disease Cause Dementia
The cells in the brain affected in PD are not in the ‘thinking’ parts of the brain and dementia is not a typical early feature of PD. However, if you have PD you have an increased risk of developing dementia. About half of people with PD develop dementia at some stage. If dementia occurs, it tends to develop in older people with PD . Early dementia in younger people with PD virtually never develops. It is thought that PD alone does not cause dementia however, other age-related factors in addition to PD may increase the risk of dementia developing.
What To Expect After Dbs
Surgery to implant the leads generally entails an overnight stay, while the IPG is usually implanted as same-day surgery. During recovery, your surgeon will talk to you about caring for your wounds, when you can shower, and any activity restrictions. Its usually recommended that any heavy lifting be avoided for a few weeks.
After another two to four weeks, youll return to have your device programmed. This process will continue for several weeks to ensure the stimulation settings are optimal to control your symptoms. During these visits, you will be shown how to turn the device on and off with the handheld device and check the battery level.
Once the programming has been completed, you will have regular follow-up visits to check and adjust the stimulation to maintain the most benefit for your symptoms.

Cognition And Mood And How To Manage Them
In this 50-minute webinar Greg Pontone, MD, distinguishes the cognitive changes commonly seen in those with dementia from the cognitive changes seen in Parkinson’s disease . He shares medications used to treat dementia and highlights those that are more effective for the cognitive changes in Parkinson’s. Dr. Pontone also talks about depression and anxiety specifically, the impact depression has on quality of life, and meditations to treat it, and how increased feelings of anxiety can be directly related to the wearing-off of medications.
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, its 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. Its also much more common in men than in women.
Parkinson disease is a chronic and progressive disease. It doesnt go away and continues to get worse over time.

Symptoms Of Parkinsons Disease
Parkinson’s disease has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Stiffness of the limbs and trunk
- Slowness of movement
- Impaired balance and coordination, sometimes leading to falls
Symptoms of Parkinsons and the rate of progression differ among individuals. Sometimes people dismiss early symptoms of Parkinson’s as the effects of normal aging. In most cases, there are no medical tests to definitively detect the disease, so it can be difficult to diagnose accurately.
Early symptoms of Parkinson’s disease are subtle and occur gradually. For example, affected people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly, or that their handwriting is slow and looks cramped or small. Friends or family members may be the first to notice changes in someone with early Parkinson’s. They may see that the person’s face lacks expression and animation, or that the person does not move an arm or leg normally.
People with Parkinson’s often develop a parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward, and reduced swinging of the arms. They also may have trouble initiating or continuing movement.
Related Diagnosis: Lewy Body Dementia
Current research is helping to differentiate dementia related conditions in relationship to Parkinsonâs disease. Doctorâs use a 12-month arbitrary rule to aid in diagnosis. When dementia is present before or within 1 year of Parkinsonâs motor symptoms developing, an individual is diagnosed with DLB. Those who have an existing diagnosis of Parkinsonâs for more than a year, and later develop dementia, are diagnosed with PDD.
In the simplest terms, Lewy bodies are abnormal clumps of proteins that develop in nerve cells. Cholinesterase inhibitors, medications originally developed for Alzheimerâs disease, are the standard treatment today for cognitive DLB and PDD symptoms. Early diagnosis is important, as DLB patients may respond differently than Alzheimerâs disease patients to certain drug, behavioral, and dementia care treatments.
This challenging, multi-system disorder involving movement, cognition, behavior, sleep, and autonomic function requires a comprehensive treatment approach to maximize the quality of life for both the care recipient and their caregiver. It is very important to pay attention to symptoms of dementia and to search for an expert clinician who can diagnose the condition accurately.

Other Medicines Used For Pd
- Catechol-O-methyltransferase inhibitors are relatively new medicines. They include tolcapone, entacapone and opicapone. These help to stop the breakdown of levodopa by the body, so more of each dose of levodopa can get into the brain to work. A COMT inhibitor is sometimes advised in addition to levodopa when symptoms are not well controlled by levodopa alone.
- Other medicines are sometimes used to help relieve symptoms. They have various effects which try to correct the chemical imbalance in the brain. They include beta-blockers, amantadine and anticholinergic medicines. One of these may be tried when symptoms are mild. However, you are likely to need levodopa or a dopamine agonist at some point.
Various things may influence which medicine is advised. For example, your age, severity of symptoms, how well your symptoms respond to treatment, if side-effects develop, other medicines that you may take, etc. Your specialist will advise on the best medicine for you to take. Whatever medicine or medicines you are prescribed, read the leaflet in the medicine packet for a full list of possible side-effects. Mention to your doctor if you develop a troublesome side-effect. A modification of the dose, dose schedule, or the type of medication, may be possible to help keep side-effects to a minimum.
How Is Parkinson’s Disease Diagnosed
There is no test that can prove that you have PD. The diagnosis is based on you having the typical symptoms . In the early stage of the disease, when symptoms are mild, it may be difficult for a doctor to say if you definitely have PD. As the symptoms gradually become worse, the diagnosis often becomes more clear.
PD is sometimes confused with other conditions. Some conditions can give ‘Parkinsonism’ features – that is, symptoms similar to PD but caused by other conditions. For example, some medicines used to treat other conditions can cause side-effects which resemble symptoms of PD. Some rare brain disorders can also cause similar symptoms.
Therefore, it is normal practice in the UK to be referred to a specialist if PD is suspected. The specialist will be used to diagnosing PD and ruling out other causes of the symptoms. They will usually be either a neurologist or a doctor specialising in elderly care. If there is still doubt about the diagnosis, sometimes a scan of the brain is carried out. This helps to differentiate PD from some other conditions that can cause Parkinsonism features. Other tests sometimes needed include blood tests and tests of your sense of smell.

Dementia And Parkinson’s Disease
In this 2-hour webinar geriatrician Naaz Parmar provides an understanding of dementia as a disease, the different subtypes of dementia, and how they affect a person with concurrent PD. This webinar also gives an overview of treatment options with lifestyle changes and medications. Coping strategies for a person with dementia and their loved ones, will also be discussed.
Language Dysfunction In Parkinsons
There are several functions within language, including naming objects, generating words, comprehension, and verbal concepts. PD most often affects a persons ability to find a word, although as PD progresses, additional language difficulties may develop, including difficulty naming, difficulty comprehending information, and the use of more simplified and less spontaneous speech.3,4

What Are The Mental And Physical Effects Of Parkinsons Disease
Parkinsons disease is a disease that affects the way the bodies substantia nigra, also known as the dopamine in the brain and nerves, communicates with the brain and nervous system. When the chemical messenger is not doing its job properly, an individual starts to feel the impacts of Parkinsons on their body and their psyche. When an individual has Parkinsons, he or she will experience various side effects and symptoms from the disease that will impact their quality of life and their every day routines.
How Does Pd Affect Dopamine
Doctors believe that PD affects the brains ability to create dopamine.7 Since the brain cannot produce the dopamine it needs, a persons movement begins to be affected. PD can also cause other symptoms as the brain begins to create less dopamine.8
People with PD can have issues with sleep, depression, and blood pressure. Younger people with PD can also have issues with impulse control.9 As you can see, these are all related to the parts of the brain that create dopamine. Doctors are not sure why this happens, or what causes PD.
PD causes the neuron cells in the substantia nigra to break down and die. People with PD have 80 percent fewer dopamine-producing cells in their substantia nigra than people without PD have.7
Doctors are not sure why this happens. If doctors can figure out why PD causes the brain to stop producing dopamine, they think they may be able to find a better treatment for PD.

Parkinson’s Disease Brain Vs Normal Brain: What’s Different
It’s not yet possible to spot the difference between a brain with Parkinson’s and a normal, “healthy” brain on an MRI scan. However, since Lewy bodies were first found in the substantia nigra in 1927, doctors have known they are a feature of Parkinson’s disease. The presence of these Lewy bodies is thought to be what separates people with Parkinson’s disease from the general population. However, Lewy bodies can only be diagnosed with certainty during a brain autopsy after death.
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.

Tom Dysfunction Is Common In Pd
Few studies focusing on ToM and PD were carried out at the beginning of the 21st century. The first study, conducted by Saltzman et al. , compared the performance of 11 non-demented PD patients with 8 age-matched HCs . They demonstrated that PD patients performed worse in false-belief stories and during a spy model task specifically, PD patients were less able to make correct predictions based on inferences regarding a story-characters belief, and they had more difficulty planning a course of action that would deceive another person. Another study, by Mengelberg and colleagues , reported that non-demented PD patients demonstrated deficits in false beliefs, short-passage tasks, and first-order story tasks, while their performance of second-order story tasks was compble to controls. Notably, the authors found more pronounced ToM deficits in the PD group with higher depression scores, and thus suggested that depression impacts on ToM processing .
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.

Physical Issues Of Your Sex Drive
Parkinsons affects ones autonomic nervous system, which controls sexual response and functioning. Parkinsons acts upon neurons in the brains substantia nigra, causing dopamine-producing nerve cells to die. Since dopamine is a chemical that transmits signals between parts of the brain that usually coordinate smooth muscle movement, this is critical to sexual function on two fronts.
Introducing an easier way to track your symptoms and manage your care.

First, this dopamine drop may result in a decreased sex drive and sexual interest. Second, the lower levels of dopamine that result are believed to cause ones loss of balance, changes in walking pattern and posture, muscle rigidity, Bradykinesia , and tremors when resting. The symptoms of Parkinsons can also be seen in:
The Nervous System & Dopamine
To understand Parkinson’s, it is helpful to understand how neurons work and how PD affects the brain .
Nerve cells, or neurons, are responsible for sending and receiving nerve impulses or messages between the body and the brain. Try to picture electrical wiring in your home. An electrical circuit is made up of numerous wires connected in such a way that when a light switch is turned on, a light bulb will beam. Similarly, a neuron that is excited will transmit its energy to neurons that are next to it.
Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapse. Chemical messengers called neurotransmitters allow the electrical impulse to cross the gap.
Neurons talk to each other in the following manner :

What Exactly Are Lewy Bodies
Lewy bodies are “clumps” of protein that accumulate in the outer layers of the brain, also known as the cortex. In addition to Parkinson’s, they are also a feature of dementia. Although we don’t know precisely what part Lewy bodies play in Parkinson’s disease or dementia, we do know that they are not the sole cause of Parkinson’s disease and its various symptoms. Some studies indicate that dopamine cells die before they even reach this part of the brain, but this is unconfirmed.
Despite the enigma of the Parkinson’s brain, many scientists have identified Lewy bodies as a potential target for new treatments. These treatments for Parkinson’s disease could be available in a matter of years, not decades.
What Treatments Are Available
Many Parkinsons patients enjoy an active lifestyle and a normal life expectancy. Maintaining a healthy lifestyle by eating a balanced diet and staying physically active contributes to overall health and well-being. Parkinsons disease can be managed with self-care, medication, and surgery.
Self careExercise is as important as medication in the treatment of PD. It helps maintain flexibility and improves balance and range of motion. Patients may want to join a support group and continue enjoyable activities to improve their quality of life. Equally important is the health and well being of the family and caregivers who are also coping with PD. For additional pointers, see Coping With Parkinsons Disease.
These are some practical tips patients can use:
Medications There are several types of medications used to manage Parkinsons. These medications may be used alone or in combination with each other, depending if your symptoms are mild or advanced.
After a time on medication, patients may notice that each dose wears off before the next dose can be taken or erratic fluctuations in dose effect . Anti-Parkinsons drugs can cause dyskinesia, which are involuntary jerking or swaying movements that typically occur at peak dosage and are caused by an overload of dopamine medication. Sometimes dyskinesia can be more troublesome than the Parkinsons symptoms.

Ask The Md: Cognitive Impairment And Parkinsons Disease
This 4:27-minute video is an explanation of cognitive changes that can happen in Parkinsons disease. Dr. Rachel Dolhun explains how doctors evaluate cognitive changes to exclude other conditions that may be correctable. She distinguishes between mild cognitive impairment and dementia, with some treatments for each.
Relationship Between Cognitive Functions And Affective Theory Of Mind
To assess the relationship between cognitive functions and affective ToM, a series of OLS regressions was performed. To see if global cognitive status may be predictive of affective ToM, independent of PD presence, MoCA total scores were regressed on RMET scores, independent of PD presence, and also controlling for depression-anxiety symptomatology , age, and gender. The results showed that MoCA total scores were significant predictors of affective ToM , deficits in cognitive functioning predicting deficiencies in affective ToM. Next, multiple OLS regressions were conducted to investigate whether the six cognitive domains of MoCA could significantly predict affective ToM, independent of PD presence, and controlling for depression-anxiety symptoms, age and gender as well. While EF , VSA , and AT appeared to be significant predictors of affective ToM abilities, MEM, L and O did not . A multiple regression model containing all of three cognitive domains explained 64% of the variance and was a significant predictor of RMET scores . However, only VSA scores remained significant predictors of affective ToM when the other two variables were controlled for . Moreover, when MoCA total scores and VSA abilities were regressed together on RMET scores, global cognitive performance also lost its predictive value .
