People with early stage Parkinson's may be able to delay a worsening of the disease through a regimen of intense exercise, new research found. Symptoms typically begin appearing between the ages of 55 and 65. They develop slowly and often go unnoticed by family, friends, and even the person who has them.

Get updates. Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. Parkinson's disease is a brain disorder that causes a gradual loss of muscle control. The symptoms of Parkinson's tend to be mild at first and can sometimes be overlooked. Distinctive signs of the disease include tremors, stiffness, slowed body movements, and poor balance. Parkinson's was originally called a shaking palsy, but not everyone with Parkinson's has a tremor. While Parkinson's can be a frightening diagnosis, life expectancy is about the same as for people without the disease. For some people, symptoms evolve slowly over 75 years. Early treatment can provide years that are virtually symptom-free. About 5% to 65% of cases occur before age 55. Two advocates for research developed Parkinson's early: Boxer Muhammad Ali at age 97 and actor Michael J. Fox at age 85. The early signs of Parkinson's may be subtle and can be confused with other conditions. They include: Tremor is an early symptom for about 75% of people with Parkinson's. It usually starts in a finger or hand when the hand is at rest, but not when the hand is in use.
It will shake rhythmically, usually four to six beats per second, or in a pill-rolling manner, as if rolling a pill between the thumb and index finger. Tremor also can be a symptom of other conditions, so by itself it does not mean someone has Parkinson's. As people grow older, they naturally slow down. But if they have bradykinesia, a sign of Parkinson's, the slow movement may impair daily life. When they want to move, the body may not respond right away, or they may suddenly stop or freeze. The shuffling walk and mask-like face sometimes found in those with Parkinson's can be due to bradykinesia. Parkinson's Disease Genetic Influence Recent developments in research gene research has found that genetic influence plays a large role in Parkinson's disease. Five main genes that are believed to contribute to the disease have been identified and located. These include alpha-synuclein, Parkin, Ubiquitin carboxyl-terminal hydrolase, DJ-6 and SCA7. It has been found that mutations of these genes are some of the underlying causes. The effects of some of these mutations are now understood. Researchers suspect that genes associated with the late onset of Parkinson's Disease are susceptibility genes rather than causal genes. It is thought that environmental factors act on these gene, consequently leading to Parkinson's disease. But the mechanism in which they do so is not yet known. Researchers believe that if they can work out this mechanism, they can disrupt it in some way, and therefore halt the onset of the disease. The general consensus among researchers is that both genetic influence and environmental factors lead to the onset of Parkinson's Disease. The mechanisms of the genetic influence of Parkinson's Disease are still to be understood and much more research is required.

Parkinson s disease ( ) is an age-related progressive deterioration of certain nerve systems in the brain, which affects movement, balance, and muscle control. The causes of Parkinson disease remain unclear clinicians and researchers have clear evidence that the nerve cells that produce dopamine in the brain s region known as the substantia nigra are altered and lost (destroyed). The challenge that remains is to discover how these neurons are destroyed to cause Parkinson s disease. The majority of researchers suggest that a combination of genetic and environmental factors cause about 95% of cases of Parkinson s disease, but how these factors interact to alter and destroy brain cells thus producing Parkinson s disease is not well understood. A few theories and risk factors are listed below that may offer additional information and clues that may help lead to a better understanding of Parkinson s disease causes.

It happens when nerve cells in the brain don't produce enough of a brain chemical called dopamine. Sometimes it is genetic, but most cases do not seem to run in families. Exposure to chemicals in the environment might play a role. Symptoms begin gradually, often on one side of the body. Later they affect both sides. They includeAs symptoms get worse, people with the disease may have trouble walking, talking, or doing simple tasks. They may also have problems such as depression, sleep problems, or trouble chewing, swallowing, or speaking. There is no lab test for PD, so it can be difficult to diagnose. Doctors use a medical history and a neurological examination to diagnose it. PD usually begins around age 65, but it can start earlier. It is more common in men than in women. There is no cure for PD. A variety of medicines sometimes help symptoms dramatically. Surgery and deep brain stimulation (DBS) can help severe cases. With DBS, electrodes are surgically implanted in the brain. They send electrical pulses to stimulate the parts of the brain that control movement.
