[Hereditary degenerative spinocerebellar syndrome with extrapyramidal symptoms]

The Authors present the linked effects of the diseases of the choreaic, parkinsonian, spinalcerebral series with those disturbances of psychic and neurovegetative nature. The discuss the difficulties of nosological grouping that this type of case presents. They conclude by affirming that in hereditary generative illnesses, as a result of the infinite number of combinations of possible symptoms and of the existence of many subdued forms, it is often of little use a forced categorization of cases into a particular clinical form.
