Different forms of Parkinson's disease
Idiopathic Parkinson's disease, whose frequency is relatively the same in all European countries, that is to say, 80 000 patients in France, represents almost all parkinsonian syndromes. Syndrome, by definition, is the group of symptoms that meet a variety of causes. Thus, parkinsonism is Parkinson's disease.
Neuroleptic parkinsonism is Parkinson's disease but one equivalent of Parkinson's disease due to the absorption of neuroleptics (medicine used for the central nervous system) these medicines to treat certain psychiatric diseases such as schizophrenia or some delusions. Among these include Haldol and Thorazine, which cause parkinsonian syndrome. The reason is as follows. The neuroleptic can block dopamine receptors, causing an obstacle to the smooth functioning, the physiological functioning (that is to say, is to say normal) of dopamine receptors. Since dopamine, receptors are not functioning properly, the patient has the same symptoms as Parkinson's disease when there is no lesion of neurons as in Parkinson's disease.
Taking neuroleptics addressing any individual neuroleptic parkinsonism is likely to occur at any age. Symptoms affect all bodies and trembling, unlike Parkinson's disease itself is not always present. Instead of this earthquake are observed febrile. This syndrome has a reversible evolution as soon as you stop taking neuroleptics. When prescribing extended, as is the case in some delusions or other neurological disorders, the symptoms described above are added abnormal involuntary movements of the mouth and tongue.
Stroke, the source of destruction of the motor system of the brain, cranial trauma repeatedly (e.g. boxing), poisoning by certain substances such as heroin adulterated, poisoning by carbon monoxide (water heater deficient ) are also likely to lead in the development of Parkinson's syndrome, however, quite different from Parkinson's disease.
Parkinson syndrome more in this syndrome, which tends to resist treatment, symptoms occur, which are not usually present in Parkinson's disease.
This is the case among others:
of supranuclear palsy, called Steele Richardson Olszewski disease, which is characterized by difficulty in directing gazed downward or upward when the patient must follow a target.
A loss of balance generally rearwardly associated with high stiffness of the cervical spine (neck) a word whose articulation is difficult intellectual difficulty concentrating.
Dementia with Lewy bodies is characterized by the appearance of disorder were associated with relatively large tunnel motor disorders that occur in Parkinson's syndrome with hallucinations fluctuate.
The corticobasal degeneration is a relatively rare and is usually characterized by the loss of manual dexterity essentially.
Note that in the past, an epidemic of an infectious nature led to the emergence of a parkinsonian syndrome. This contagious cause, which no longer exists today, is likely to explain the ability of some microbes to destroy areas of the brain (nigrostriatal system) and cause the appearance of a neurological disease like Parkinson's.
