In psychology, logorrhea or logorrhoea (from Ancient Greek λόγος logos "word" and ῥέω rheo "to flow") is a communication disorder that causes excessive wordiness and talkativeness, which can sometimes lead to incoherency. Logorrhea is sometimes classified as a mental illness and can result from a variety of psychiatric and neurological disorders[1] including aphasia,[2] localized cortical lesions in the thalamus,[3][4] mania,[citation needed] or most typically in catatonic schizophrenia.[citation needed]

Examples of logorrhea might include talking or mumbling monotonously, either to others, or more likely to oneself. This may include the repetition of particular words or phrases, often incoherently. The causes of logorrhea remain poorly understood, but appear to be localized to frontal lobe structures known to be associated with language. As is the case, for example, in emotional lability in a wide variety of neurological conditions, other symptoms take priority in clinical management and research efforts. Other symptoms include excessive talking, words that avoid any logic or reason, words that may offend other people and random words which hearers may ascribe unintended meaning to.

Logorrhea should not be confused with pressure of speech, which is characterized by the "flighty" alternation from topic to topic by tenuous links such as rhyming or punning.[5] Logorrhea is a symptom of an underlying illness, and should be treated by a medical professional.[citation needed]
