Parkinson disease- Treatment and Information

Parkinson's disease (also known as Parkinson disease or PD) is actually a degenerative disorder of the central nervous system that often impairs that the sufferer's motor skills, speech, and other functions.

Parkinson's disease belongs to a group of conditions that called movement disorders. It is characterized by the muscle rigidity, tremor, a slowing of physical movement (bradykinesia) and, but in extreme cases, a loss of physical movement (akinesia). The major symptoms are the results of decreased stimulation of the motor cortex by the basal ganglia, generally caused by the insufficient formation and action of dopamine, which is produced that in the dopaminergic neurons of the brain. Secondary symptoms that may include high level cognitive dysfunction and the subtle language problems. PD is both chronic and that progressive.

Parkinson Disease Overview

Parkinson disease (PD) is an age-related deterioration of the certain nerve systems, which affects your movement also balance, and muscle control.

* Parkinson disease is one of the upmost common movement disorders, affecting 1% of people older than the 60 years. PD is about 1.5 times more common that in men than in women, and it so becomes more common as you age.

* The average age of onset is that about 60 years. Onset before age 40 years is rather uncommon, but the very recent diagnosis of actor Michael J. Fox shows that younger people are also vulnerable.

* In PD, brain cells deteriorate (or degenerate) that in an area of the brain called the significant nigra. From the substantia nigra, specific nerve cell tracts connect to another part of the brain and its called the corpus striatum, where the neurotransmitter (a chemical messenger in the brain) called the dopamine is released. Dopamine is an imperative neurotransmitter and the alterations in its concentration can lead to different medical problems.
Treatment

Treatment isn't always needed much in the early stages of Parkinson disease � mild tremor, for example, it may be inconvenient and cause social embarrassment but otherwise that life can go on pretty much as normal by parkinson diseases.

But as the disease progresses, it will typically be treated with drugs. Several different drugs are available in market . They all work in much and the same way � by boosting the depleted levels of dopamine in to the basal ganglia.

The best known of these is Levodopa and it also called L-dopa. When this drug was introduced in the 1960s it was a great revolution in the treatment of Parkinson's disease. It crosses with no trouble from the bloodstream into the brain tissue, where it is broken just down to become dopamine. The symptoms of tremor and severity disappeared overnight.

However, L-dopa didn't quite live up to its near the beginning promise. The effect of the drug wears off that in patients after three to five years, meaning dosage has to be increasingly increased to get the same therapeutic effect. Side effects � frequently abnormal involuntary muscle movements called the dyskinesias � also become ever more severe, and may even be worse that than the disease itself.

So these days, doctors often hold off just giving L-dopa treatment in the early stages of Parkinson's, reserving it for when symptoms get somewhat more serious. And they often combine L-dopa with other drugs that very help maintain dopamine levels, such as carbidopa (this may be combined with L-dopa in one preparation; the trade name is the Sinemet). Other supplementary drugs that include amantadine, bromocriptine and pergolide.
