title: [Mutism as permanent catatonic condition].
abstract: The history of a case of mutism, where the patient had been silent for more than twenty-five years, caused by the author to study and discuss this relatively infrequent catatonic symptom which is a type of schizophrenia, with frequent references being made to the results of psychiatric studies made by authors ranging from Kahlbaum to Leonhard. Permanent mutism as a possible phenomenal form was logically classified, by Leonhard, as a type of mannered catatonia.
