There Is A Strong Genetic Link To The Disease
“For about 10-15% of all PD cases, we know that there is a strong genetic link to the disease,” says Beck. “There is a lot of research right now studying DNA from people with PD including a major study from the Parkinson’s Foundation, PD GENEration: Mapping the Future of Parkinson’s Disease and scientists have discovered many genetic mutations linked to PD. But even when someone has a genetic mutation associated with PD, that does not necessarily mean they will develop the disease. Scientists are just beginning to understand the full role that genes play in PD. It is possible that certain genes may cause PD while other genes may actually protect people from developing it.”
Study Subjects And Design
We used a prospective propensity score-matched cohort design to study the effect of PD on the risk of developing subsequent ischemic stroke. To control for potential confounding from imbalance in clinical characteristics, we used propensity score matching to create comparable cohorts between patients with and without PD , . The study population consisted of a PD group and a non-PD group, both selected from Taiwanese residents in the complete NHI claim database in 2001, in which more than 21.6 million persons were registered.
What Is Parkinsons Disease
Parkinsons disease is a nervous system disease that affects your ability to control movement. The disease usually starts out slowly and worsens over time. If you have Parkinsons disease, you may shake, have muscle stiffness, and have trouble walking and maintaining your balance and coordination. As the disease worsens, you may have trouble talking, sleeping, have mental and memory problems, experience behavioral changes and have other symptoms.

Independance Motivation And Hope
My son Sharat suffered a severe traumatic brain injury 23 years ago leaving him with Aphasia and right sided weakness from his vision,hearing to his limbs. The lockdown in June was a great challenge for him as his caregivers stopped coming, no gym workouts and no outings for a coffee.
Being his mother and primary carer I feared that this was a hotbed for depression. I scoured the net and chanced upon FlintRehab. As there was a trial period it was safe for us to risk getting it across to Auckland.
His OT checked it out and felt that it was ideal. I can honestly second this.
He enjoys working on it and now after three months can do it on his own. His left hand helps his right hand. The FitMi video explains and shows him what to do, it gives him marks and applauds him too!!
He has to use both sides of his brain. The caregivers are OT students who returned enjoy working on it with him.
In three months there motivation built up in him with a drive to use his right hand. There is definitely a slight improvement in his right hand.
This encourages him as well as the caregivers to try harder.His overall mood is upbeat. He enjoys it, so much so, that it doesnt matter if his caregiver is away.
FitMi is a blessing.
Diagnosing Tremors After Stroke
If a stroke patientdevelops tremors, it usually begins months after the stroke.
Of all the involuntary movement disorders after stroke,tremor has the longestdelayed onset.
Because of this delayed onset, it can be difficult todiagnose the cause of the tremors because new conditions may have developed.
For example, shaking hands after stroke could indicate a completelyseparate medical condition called Parkinsons disease, which is aneurodegenerative disease that affects movement. Its an unfortunate dominoeffect of neurological degeneration.
Aside from Parkinsons disease, there are 16 other possible conditions that cancause tremors. Therefore, working with a doctor is essential to properlydiagnose your condition.
If it turns out that stroke is the only cause of your tremors after stroke, then the following treatments can help.

What Are The Surgical Treatments For Parkinsons Disease
Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.
Epidemiology Of Depression Post
Epidemiological studies of depression post-stroke are fraught with a variety of methodological problems related to ascertainment bias, rating of depression, and the heterogeneity of cerebrovascular disease. The peak incidence of depression is between six months and two years post-stroke and point prevalence for depression varies between 1034% according to studies. In one large, US based, community epidemiological study, patients with depression post-stroke were more likely to be younger, more often white and less likely to be alive three years post-cerebrovascular accident than those who were not depressed post-stroke.
Other risk factors for depression include functional and cognitive impairment, a past history of depression, and a lack of social support

Could Parkinson’s Disease Raise Stroke Risk
Or is the link the other way around? Study finds a connection, but cause-and-effect isn’t clear
However, the study can’t prove that one condition causes the other — or even which direction the link might travel, the researchers said.
For example, maybe Parkinson’s somehow raises a person’s odds for ischemic stroke — the type that’s caused by a clot and makes up the vast majority of strokes. Or, it could be that having a stroke weakens the brain, raising the risk that a patient will develop Parkinson’s.
Or, as one expert who reviewed the findings said, a separate, unknown factor might independently link the two conditions.
“There may be some processes that occur with aging that increase the risk of bothstroke and neurodegenerative disorders” such as Parkinson’s, said Dr. Andrew Feigin, a neurologist at Northwell Health’s Neuroscience Institute in Manhasset, N.Y.
More study will be needed to unravel the connection, said a team of researchers led by Dr. Benjamin Kummer, of Weill Cornell Medical College in New York City.
In the study, Kummer’s team tracked outcomes for a sample of about 1.6 million U.S. Medicare recipients between 2008 and 2014.
How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.

What Are The Symptoms Of Vascular Parkinsonism
Most of the well-known symptoms of PD are also present in vascular Parkinsonism. With vascular Parkinsonism, muscle control challenges are more concentrated in the lower body, whereas with PD, they tend to affect the entire body.
While tremors are common in people with PD, it isnt a key symptom of vascular Parkinsonism. Some people with the vascular condition experience a resting tremor, but this usually occurs later in the course of disease.
The main symptoms of vascular Parkinsonism include:
Tremors After Stroke: Causes Diagnosis & Treatment

Silent Stroke Can Cause Parkinson’s Disease
- University of Manchester
- Scientists have for the first time identified why a patient who appears outwardly healthy may develop Parkinson’s disease.
Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson’s disease.
Whilst conditions such as a severe stroke have been linked to the disease, for many sufferers the tremors and other symptoms of Parkinson’s disease can appear to come out of the blue. Researchers at the university’s Faculty of Life Sciences have now discovered that a small stroke, also known as a silent stroke, can cause Parkinson’s disease. Their findings have been published in the journal Brain, Behavior, and Immunity.
Unlike a severe stroke, a silent stroke can show no outward symptoms of having taken place. It happens when a blood vessel in the brain is blocked for only a very short amount of time and often a patient won’t know they have suffered from one. However, it now appears one of the lasting effects of a silent stroke can be the death of dopaminergic neurons in the substantia nigra in the brain, which is an important region for movement coordination.
The team then analysed changes in the brain six days after the mild stroke and found neurodegeneration in the substantia nigra. Dopaminergic neurons had been killed.
How Is It Diagnosed
Diagnosing vascular Parkinsonism starts with a thorough review of your current symptoms and medical history, including your family medical history. A physical examination and a review of your current medications are also necessary.
To make sure your doctor gets an accurate diagnosis, brain imaging is critical. A 2019 scholarly review article suggests that an MRI of the brain can help determine whether your symptoms are caused by vascular Parkinsonism or PD. An accurate diagnosis is an important step in getting the most effective treatment.
Other brain imaging, such as a CT scan, can also be helpful for detecting signs of small strokes in the regions of the brain responsible for movement and muscle control.

What Are The Different Stages Of Parkinsons Disease
Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.
In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:
Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.
Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.
Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.
Two Areas In Which Parkinsons Disease May Bring About Death
PD patients are at an increased risk of falling and bad falls can lead to death. This usually occurs as a complication of a fall that requires hospitalization, particularly if it involves surgery. While most people do not fracture their hips when they fall, some do, and hip surgery, while routine, is still major surgery. It carries the risk of infection, delirium related to pain medications and anesthesia, heart failure, pneumonia, blood clots in the legs that then go to the lungs, and general weakness from immobility. Hip fractures are probably the main cause for death for those who fall, but people can fracture other bones and require surgery. They may fracture their ribs, which leads to reduced coughing, because of the pain, and an increased risk of lung infections . It is surprisingly uncommon for Parkinsons Disease patients to die from brain injuries related to falls, but it still may occur.
PD patients also may develop pneumonias completely unrelated to difficulties with swallowing, just like their non-PD friends and relatives.

Diagnosis Of Depression Post
A number of factors can make the diagnosis of depression difficult post-CVA. Communication difficulties, impairments of facial and emotional expression, and disturbance in vegetative functions can make assessment of mental state extremely difficult. A deterioration in function over a few days or weeks following a period of improvement is one clinical clue for the development of depression.
Extreme abulia can sometimes be mistaken for depression and can be related to either frontal and diencephalic lesions. The patient may appear to be extremely retarded but may function at a high level within a structured environment. Dopamine agonists, such as bromocriptine, have been used to treat abulia.
Pathological emotionalism is relatively common after stroke, affecting up to 20% of patients in the first six months post-stroke but tending to improve over the following year. Severe examples of pathological emotionalism have been treated with antidepressant medication and levodopa.
Stratified Analysis Of Psp And Mortality
A multivariable model was used to analyze the data of 13,846 poststroke patients. Table 3 demonstrates compared with the comparison cohort, the mortality risks in patients aged 40 to 64, 65 to 74, and 75 years were respectively 2.32-, 2.02-, and 1.93-fold higher mortality risks in the total stroke cohort 2.21-, 1.91-, and 1.86-fold higher mortality risks in the PSN cohort and 4.57-, 2.84-, and 2.27-fold higher mortality risks in the PSP cohort. Moreover, compared with the comparison cohort, the total stroke, PSN, and PSP cohorts demonstrated respectively 1.99-, 1.88-, and 2.81-fold higher mortality risks in female patients and 1.92-, 1.77-, and 3.02-fold higher mortality risks in male patients. Patients without any comorbidity in the total stroke, PSN, and PSP cohorts had 2.23-, 2.09-, and 6.46-fold higher mortality risks than did those in the comparison cohort, respectively, whereas those with any one comorbidity had 1.97-, 1.87-, and 2.55-fold higher mortality risks, respectively .

Depression In Parkinsons Disease
Diagnosis and management of depression in Parkinsons disease is important for two main reasons: firstly, depression is common in PD , and secondly depression causes significant morbidity in terms of quality of life, disability , and carer stress. This effect is independent from the effect of motor disability.
Symptoms Of Tremors After Stroke
Tremors involve unintentional, uncontrollable rhythmic movement in the body.
There are many different types of tremors. The onemost commonly seen in stroke patients is called an essential tremor.
After stroke, essential tremors are most commonly seen inthe hands and arms. This is when some stroke patients notice their hand shakingafter stroke.
Its important to note that tremors are different frommuscle spasms and twitches, which are a sign of spasticity.Tremors are not the same as spasticity.
Furthermore, tremors can easily be confused with clonus after stroke,another type of unintentional rhythmic shaking. However, clonus can betriggered by stretching while tremors are not.
With many different types of involuntarymovement disorders, its important to work closely with your doctor for anaccurate diagnosis. An accurate diagnosis helps you receive proper treatment!
Next youll learn about the potential causes of tremors after stroke.
Brain Injury And Parkinsons Disease
Head injuries can increase a persons risk of developingParkinsons Disease and other forms of parkinsonism.
However, even with the increased risk, it is still a rareside effect of brain injury. Only about 1% of TBI patients will experienceparkinsonism.
If you do end up diagnosed with post-traumatic parkinsonism, treatment will most likely involve a combination of physical therapy and medication.
Does Head Injury Lead To Parkinsons Disease
According to a study published in the journal Neurology, a head injury, specifically a mild traumatic brain injury , does in fact lead to an increased risk of PD. The study was conducted using the VAs databases and identified all patients treated by the VA with TBI. The results found that:
- Patients with mild TBI and brief loss of consciousness had a 56% increased risk of developing PD compared to patients without any history of head injury.
- Patients with severe TBI were at an 80% higher risk of PD compared to healthy subjects.
- A single mild TBI with no loss of consciousness did not lead to a significant risk increase for PD.
Although head injury does increase a persons risk of PD, it should be noted that the likelihood of developing the full disease is still relatively low. In fact, in the study, only about 1% of patients were diagnosed with PD.
What is more likely, however, is that a person might develop a form of parkinsonism.
