Historical note: Jules Séglas on language in dementia.
In his book Des troubles du language chez les aliénés (1892) Séglas applied the model of language processing of his teacher, Charcot, to analyze the language disorders of various groups of mentally ill, including patients considered to suffer from dementia. Among the language phenomena he described from dementia are logorrhea, neologisms, embolalia, near-mutism, angophrasia, automatic speech, alexia, and agraphia. Séglas must be credited for his early descriptions of how language behaviors cluster in various psychiatric and dementing diseases.
