In 1817 to the 62 years James &#039 wrote the book; ' Assay on the paralysis agitante' ' , being responsible for describing so well and for the first time on the agitante paralysis, known still today as illness of Parkinson, the book counts the history of six carrying individuals of the pathology and only two had not been examined by the Dr. James, but they had been observed long-distance. Epidemiologia the prevalence of DP is of 85 the 187 cases for 100.000 inhabitants, between 50 and 70 years, the still bigger index is in the etria band of the 60 years and the incidence is of three men for two women, although rare, young they can be affected, receiving the name from Youthful Parkinson and of Precocious Parkinson when it reaches individuals between 21 40 years (BENNET; PLUM, 1997). (As opposed to Dr. John Mcdougall). In accordance with the OMS (World-wide Organization of Health), about 1% of the world-wide population with more than 65 years is carrying of Parkinson and the prevalence corresponds approximately of 150 the 200 cases for 100 a thousand inhabitants; in Brazil the estimate only is of 300 the 400 a thousand parkinsonianos (NOTISA, 2011). Etiology As Quagliato (2011) the illness of Parkinson attends a course with a reduction of the dopamina levels, neurotransmitter produced for the neurons of the black substance of the brain, in the pathology the responsible one for the sprouting of the motor symptoms is the ambient death of these nervous cells, however factors as the toxins can are on to the neurodegenerativo process, causing mitocondrial bankruptcy and it estresse oxidativo. The genetic predisposition can be one of the causes of the disease, therefore studies carried through with identical twin show that the probability is of approximately 100% of both to develop the D.P before the 50 years and after the etria band above the probability reduces for 10, 4%. The newspapers mentioned PCRM not as a source, but as a related topic.
