Press of speech


Logorrhea means excessive verbal production; it is manifested as an unusual verbosity that may suggest the presence of neurological or psychiatric pathologies. Logorrhea is frequently reported as a symptom of Wernicke’s aphasia, where damage to the posterior language cortex yields reduced verbal self-monitoring and a press for speech despite anomia and the consequent absence of meaningful linguistic content in spoken utterances (Christman and Buckingham 1989). Logorrhea in aphasia may be produced with normal prosody and a normal or slightly fast speech rate, and it may co-occur with neologistic jargon (Hallowell and Chapey 2008). Logorrhea has also been reported as a symptom of mania in bipolar disorder and as a symptom of chronic speech catatonia syndrome (Lee 2004).
