What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.
Cat Head Shaking Like Parkinsons Causes & Treatments

Treatment Of Essential Tremor
There is no cure for essential tremor. Treatment aims to suppress the involuntary movements.;To identify the best treatment, you should consult with a Neurologist. Treatments can include:;
- avoidance of known triggers, such as alcohol or caffeine
- some medications used to treat other medical conditions, such as heart disease and epilepsy these medications have been helpful in some cases
- other medications, including tranquillisers
- deep brain stimulation, a surgically implanted device that helps to short-circuit the impulses or brain waves causing the tremor
- brain surgery to alter the part of the brain causing the tremor has been successful in some cases
- MRI guided focused ultrasound
- regular monitoring and observation if the tremor is mild and doesnt stop the person from performing their usual activities, this may be the only treatment.
In some cases, alcohol may reduce the tremors. However, this is not a recommended treatment, because long-term consumption of alcohol has significant health risks.

I thought I had Parkinsons disease! the 65-year-old stock analyst exclaimed.
Over the past six months, her handwriting had deteriorated to the point that she was having difficulty signing checks. Because a good friend of hers had recently received a diagnosis of Parkinsons disease, she feared the worst.
I began to suspect that her concern was groundless when I noticed that both of her hands shook and that she had a barely noticeable to-and-fro motion of her head two signs that are uncommon in Parkinsons disease.
And as she walked toward the examining room, her gait was normal and her arms swung freely hardly the stiff, hesitant shuffle so often seen with Parkinsons.
The exam turned up none of the other cardinal manifestations of Parkinsons: the typical masklike facial expression; the slowed, monotonous speech pattern; and the ratchet-like sensation the examiner feels when alternately flexing and extending the patients arm.
Moreover, her hand tremors seemed to improve at rest and worsen when asked to do the finger to nose test.
The diagnosis was unmistakable: She had essential tremor, a nervous-system problem that causes unintentional shaking, most often starting in the hands.
Difference Between Parkinsons Disease And Parkinsonism
Parkinsonism;is an umbrella term used to describe a group of movement disorders that share similar symptoms.
The signs of parkinsonism include:
- Resting tremors
- Difficulty with balancing and walking
Parkinsonism can also cause people to perform uncontrolled, repetitive movements, known as tics.
PD is the most common type of parkinsonism, but there are other types that have more specific causes, such as:
- Drug-induced parkinsonism.;This occurs when a person takes a medication that lowers dopamine levels. Symptoms usually disappear once the medicine is stopped.
- Vascular parkinsonism.;Stroke can cause certain parts of the brain that control movement to die, leading to Parkinson-like symptoms.
- Post-traumatic parkinsonism.;Brain damage to the;cerebellum;or;basal ganglia;can also cause movement disorders that look a lot like Parkinsons Disease.
Whether you have PD or some other form of parkinsonism, treatment will mostly be identical.

Cause Of Essential Tremor
Essential tremor is the most common type of tremor, and affects more people than Parkinsons disease. Some estimates suggest that around 1 in 5 people over the age of 65 years is affected.
There is no known cause, but a genetic link is strongly suspected. Each child of a person with essential tremor has a 50% chance of inheriting the disorder themselves. If a person with essential tremor has other affected family members, then the disorder is called familial tremor.

Stiffness In Walking Or Movements
People often experience stiffness that is not due to exercise or lack of exercise. Some people have mentioned that they feel like their feet are stuck to the floor.;
The person may start taking smaller steps or dragging or shuffling their feet. They also may have difficulty gauging the size of steps to take. And things like the length of their stride can cause people to trip and fall.;
Is Essential Tremor Treatable
Theres no cure for essential tremor, but the progression of symptoms is gradual and slow. There are also treatments that may help relieve your symptoms. You may not need treatment if your symptoms are minor.
Your doctor will advise treatment if your symptoms are severe and interfering with your normal activities. Treatment options include:

Stiffness And Slow Movement
Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.
Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.
Can Parkinsons Disease Be Prevented
Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

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.
Feline Infectious Peritonitis Or Fip
FIP is a viral disease that affects both wild and domesticated cats. It is caused by a coronavirus that attacks the cells of the intestinal walls.; Its symptoms include a fever that does not respond to antibiotics, weight loss, lethargy, and labored breathing. Since it also affects the neurological system it oftentimes leads to head shaking and seizures. Cats affected with FIP usually wont be able to survive, fortunately, this is a rare condition and seldom happens in households with only one or two cats.;

What Causes Essential Tremor
The cause of essential tremor is unknown. However, one theory suggests that your cerebellum and other parts of your brain are not communicating correctly. The cerebellum controls muscle coordination.
In most people, the condition seems to be passed down from a parent to a child. If your parent has ET, there is a 50% chance you or your children will inherit the gene responsible for the condition. Sometimes, ancillary testing such as brain imaging or genetic testing may help with the diagnosis.

What Are The Types Of Tremor
There are several types of tremor, including
- Essential tremor, sometimes called benign essential tremor. This is the most common type. It usually affects your hands, but it can also affect your head, voice, tongue, legs, and trunk.
- Parkinsonian tremor, which is a common symptom in people who have Parkinson’s disease. It is usually affects one or both hands when they are at rest, but it can affect the chin, lips, face, and legs.
- Dystonic tremor, which happens in people who have dystonia. Dystonia is a movement disorder in which you have involuntary muscle contractions. The contractions cause you to have twisting and repetitive movements. It can affect any muscle in the body.
Can Essential Tremor Increase The Risk For Other Illnesses
Essential tremor is linked to other illnesses. Other movement disorders, such as Parkinson’s disease, have been associated with ET. Some reports have linked ET with migraine headaches. People with ET may also be at high risk of having dementia .
Drugs that treat essential tremor may also make you more likely to become depressed.
Some experts think thereâs no increased risk for Parkinson’s disease for people with ET. Instead, some people diagnosed with ET may be incorrectly diagnosed at first and later turn out to have Parkinson’s.

While you may be familiar with Parkinsons disease, essential tremor is much less known, yet much more commoneight times more common, in fact.
Parkinsons disease is a progressive disease of the nervous system noticeable by resting tremor, balance issues, muscular rigidity, and slow movement. It typically affects middle-aged and elderly people. In addition to motor symptoms, Parkinsons patients can also experience depression, sleep disorders, loss of smell, constipation. In Parkinson plus syndrome, patients can also have autonomic dysfunction, cognitive impairment, and hallucinations. Approximately 60,000 Americans are diagnosed with Parkinsons disease every year. The cause of Parkinsons disease is unknown.
Essential tremor is one of the most common movement disorders in the world that seems to strike people over age 40. It is a progressive condition which starts with an uncontrollable movement of the hands when trying to reach something. Essential tremor can happen in the vocal cords, the head, and the legs. Even the early stages, essential tremor can make life difficult. You may have trouble writing, holding things, putting key to the lock, and preforming fine movement in your job. Tremor can stop after drinking alcohol. Essential tremor is believed to be caused by a genetic mutation can be inherited.
What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.
Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.
Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal; and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.
