Parkinson's Disease

The earliest known record of the study of Parkinson’s Disease is mentioned in James Parkinson’s “Essay on the Shaking Palsy”. The article describes the most common features of the disease which remain as the standard by which other types of parkinsonism are compared. The disease is mainly characterized by trembling of the limbs, muscular stiffness, and slow body movement. In addition, individuals suffering from the disease exhibit the following: standing in a stooped posture; walking in short, shuffling steps, and speaking softly in a rapid and even tone. In most cases, 60 to 80 percent of an individual’s dopaminergic neurons – dopamine-producing cells of the body – are already non-functional by the time Parkinson’s disease has been diagnosed.
The mechanism which causes Parkinson’s disease remains unknown. Its pathological classification describes it as a systemic degeneration of the brain which targets specific cells in the brain. In 1908 Dr. Frederick Lewy discovered abnormal structures in the brain associated with Parkinson’s Disease. Called Lewy bodies, these structures are not found in other forms of parkinsonism. It has been theorized that a premature aging process, unknown nutrient deficiency or toxin may be causing the deterioration of the substantia nigra.
Tremors
Tremors are the most common of Parkinson’s disease, as observed in 50 percent of reported cases. It is the involuntary rhythmic movement of a body part which may occur during rest or when an individual performs a certain movement or action. ...

Brain mechanisms underlying Parkinson disease.
Parkinson’s disease (PD) is a slowly occurring, neurodegenerative disease. It occurs as a result of degeneration of neurons within the substantia nigra, which is a region of the brain responsible for controlling movements. Degeneration of neurons leads to the shortage of dopamine, which controls body movements. With a reduction in the production of dopamine, the body suffers from impaired movements. Symptoms associated with PD start to show up later in life when a person attains the age of 40 years and over. Parkinson’s disease are terms used to distinguish PD from other forms of...
