Parkinson 's Disease Affects The Brain

Each year more than 60,000 Americans are diagnosed with Parkinson’s disease (PDF, 2014). That sixty thousand does not include the many thousand cases that go undetected each year. Parkinson’s is a progressive disorder that occurs in the nervous system. This disease affects a person’s movement. Parkinson’s disease develops progressively. The most common first sign of Parkinson’s is slight shaking of a body part. In the initial phase of Parkinson’s a person will experience slurring of speech and an expressionless face (Mayo Clinic, 2014). With time, the symptoms of Parkinson’s exacerbate. This disease is most frequently seen in people over the age of 50 (PDF, 2014). Parkinson’s disease is generated by a great number of reasons.

Parkinson’s disease “is described as a common disorder of the brain caused by a progressive deterioration of the areas that produce the neurotransmitter dopamine” (Fischer, 1999). It affects the nervous system, more specifically it affects the nerve cells in your brain that secrete dopamine. Dopamine is a chemical that is responsible for the movement and coordination of the musculoskeletal system.

Parkinson’s disease is a progressive disorder of the central Nervous system and affects both motor and nonmotor functions. parkinson 's is caused by a chemical imbalance within the brain. The brain produces a neurotransmitter called dopamine in the basal ganglia, which is structures linked to the thalamus in the base of the brain. If the Dopamine, Basal ganglia and Thalamus does not function properly then causes major damage,. A person having less and less dopamine, the individual has less and less ability to regulate their movements, body and emotions. Although there is no current cure available for Parkinson’s disease, the debilitating conditions can be lessoned through education, therapy, and a variety of treatments to improve their quality of life on the National Parkinson Foundation website.

Parkinson's Disease affects the way the body moves, in the brain, there's an important chemical called Dopamine which controls movements that the body makes and sends signals to the brain to tell the body where to move. Having Parkinson's Disease, the nerve cells in the brain break down to where there isn't enough dopamine and have trouble controlling movements . Figure 1, shows a before and after picture of where in the brain the nerve cells which contain dopamine are located and how the nerve cells become damaged when a person has Parkinson's.

Parkinson's disease is a progressive neurological disorder that slowly erodes an individual's ability to care for themselves. Parkinson's does not have a standard set of symptoms and each person's experience with Parkinson's is unique. What is common is that the disease affects the body's ability to control muscle movements. This may result in tremors, muscle rigidity, difficulty walking, and an inability to perform any task requiring fine motor skills. There is no known cure for Parkinson's disease, and its progressive nature ensures that it is highly debilitating.

Parkinson Disease is a brain disorder that affects movement, loss of muscle control and balance. The first symptoms usually include a tremor of the hand, foot, or leg which is often termed as a “shaky palsy.” The disease usually slowly progresses with symptoms getting more intense over many years. Some patients who develop Parkinson’s in their younger years have faster, more rapid, symptom signs. Much quicker than those who develop the disease at an older age. Most patients develop the disease after the age of 60 and as of 2017, there is still no cure for Parkinson’s Disease.

Parkinson's disease is neurodegenerative brain disorder that affects the brain and nervous system. When someone get Parkinson's it slowly develops in most people who get the disease. PD or Parkinson’s Disease affects people when they start to reach 60 years old. When a person is diagnosed with Parkinson's disease the brain slowly stops producing a neurotransmitter called dopamine. The less dopamine a person has the harder it is to control their abilities to regulate their emotions and body motions. Imagine not having any control of your hands, legs, arms, and emotions… heartbreaking. There is currently no cure for Parkinson's disease right now but with your help and donations made out to the michael J. Fox

“The disease is caused by the death of cells in one of the movement control centers of the brain” (Sick!). More than one million people in the United States are affected by this disease, and about 60,000 new cases are diagnosed each year with an equal frequency and men and women. It usually develops when a person is in his or her late 50s or early 60s. Parkinson's Disease develops gradually, but continues for long periods of time, usually many years. When brain cells die in the substantia nigra, it doesn't release enough dopamine. Dopamine is a neurotransmitter that helps send signals that control movement, and without it, signals cannot travel from substantia nigra brain cells to other parts of the body. This makes every day movement like walking and writing to not occur correctly. Researchers have not yet discovered the basic cause of Parkinson's disease, but some think the disease is hereditary or caused by environmental factors. Some of the symptoms of Parkinson's Disease are tremor (shaking), slowing down of movements, muscle rigidity (stiffness), problems with posture and balance, depression, changes in the way a person speaks, sleep problems, emotional changes, incontinence (loss of bladder control), changes in handwriting, and dementia (problems with mental functions). There is no known treatment or way to prevent Parkinson's disease

These tremors are most often seen in hands and the feet, but can be seen throughout the entire body. Tremors seem to be the worst when a person is a rest, but subside when a person is active, and completely disappear only when a person is sleeping. Parkinson’s people also have a significant amount of rigidity. They have what you call “cogwheel” movement, where they move in segments per say.(Parkinson’s Disease n.d.) They also have a “lead pipe” movement which as you can guess is heavy moments of the limbs. Loss of postural reflexes is another huge give away for Parkinson’s. People with this disease have a hard time standing up right, and are flexed and hunched over at all joints including the back, hips and knees. You can see the picture on the right is of a very severe case of Parkinson’s, he is showing that bent posture in all positions. Back to the lack of dopamine which I explained before was an inhibitory neurotransmitter, a patient with Parkinson’s becomes very unstable and is less able to make compensatory changes to regain their balance. Those diagnosed have a very distinguished gait pattern, which is another dead giveaway. Because they are flexed forward and have a hard time with their center of gravity, they start to shuffle their feet and fall forward, which is called festinating. There is a significant delay between planning to move and actually moving. They now require

Parkinson’s Disease is known as one of the most common progressive and chronic neurodegenerative disorders. It belongs to a group of conditions known as movement disorders. Parkinson disease is a component of hypokinetic disorder because it causes a decreased in bodily movement. It affects people who are usually over the age of 50. It can impair an individual motor as well as non-motor function. Some of the primary symptoms of Parkinson’s disease are characterized by tremors or trembling in hands, legs and arms. In early symptoms the tremor can be unilateral, appearing in one side of body but progression in the disease can cause it to spread to both sides; rigidity or a resistant to movement affects most people with Parkinson’s disease,

What is Parkinson’s disease? Parkinson’s is a progressive condition by a loss of never cells in the brain known as neurodegeneration. The cause of neuronal loss in Parkinson’s is still unknown. However, the symptoms can still be explained by the loss of cells that contain neurotransmitter called dopamine. Dopamine is a type of chemical that nerve cells release to communicate with other nerve cells. It is just not responsible for doing that, dopamine has many other functions it must do including important roles in behavior, voluntary movement, motivation, sleep, mood, attention, working memory, and learning. So, in Parkinson’s the neurons that produce dopamine slowly start dying. When dopamine levels get, lower this will cause an imbalance with the other neurotransmitters and will result with confusing both motor and non-motor symptoms which will get worse overtime. (Sethi 2002) Parkinson’s is a really known disease as Alzheimer’s it is said that there is an estimated number of up to 1.5 million Americans suffering from the disorder at any given time. (Mayo Clinic Staff, 2015)

About one million Americans and four million people worldwide suffer from Parkinson’s disease. The number of individual’s with Parkinson’s increases by at least sixty thousand per year in America. Although the Parkinson’s disease has been around for thousand of years, it was not officially recognized until 1817 by a Dr. James Parkinson. Dr. James Parkinson clearly stated in his paper An Essay on the Shaking Palsy symptoms of Parkinson’s that are still recognized today as markers for the disease. Even though he wrote that paper in 1817, it was not until 1861 that the medical community began to collectively look into this debilitating disease.

Parkinson's is a chronic and progressive movement disorder and it worsens over time. Nearly a million people are living with Parkinson's in the us. There is no known cure but there is medication and surgery which can help manage the symptoms. the cause is unknown.Parkinsons involves the death of neurons in the area of the brain called the Substantia Nigral. Some of these neurons release dopamine a chemical that sends messages to the part of the brain in charge of movement and coordination.As Parkinson's progresses the amount of dopamine decreases leaving the brain unable to control movement normally. The symptoms of Parkinson's are the slowness of thought, Forgetfulness

Definition: “Parkinson’s disease is a chronic, progressive disease of the nervous system characterized by the cardinal features of rigidity, bradykinesia, tremor, and postural instability” (O’Sullivan and Schmitz, 2007). The condition can develop between age group 60 and 80 years and symptoms mostly appear around 60 years of age (O’Sullivan and Schmitz, 2007).

Parkinson disease (PD) is a progressive neurodegenerative disorder characterized mainly by physical and psychological disabilities. This disorder was named after James Parkinson, an English physician who first described it as shaking palsy in 1817 (Goetz, Factr, and Weiner, 2002). Jean- Martin Charcot, who was a French neurologist, then progressed and further refined the description of the disease and identified other clinical features of PD (Goetz, Factr, and Weiner, 2002). PD involves the loss of cells that produce the neurotransmitter dopamine in a part of the brain stem called the substansia nigra, which results in several signs and symptoms (Byrd, Marks, and Starr, 2000). It is manifested clinically by tremor,
