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 repetitiveness, which can sometimes lead to incoherency. Logorrhea is sometimes classified as a mental illness, though it is more commonly classified as a symptom of mental illness or brain injury.


Logorrhea is characterized by the constant need to talk.[1] Other related symptoms include the use of neologisms (new words without clear derivation), words that bear no apparent meaning, and, in some extreme cases, the creation of new words and morphosyntactic constructions.[2] Logorrhea should not be confused with pressure of speech, which is characterized by rapidity of speech and "flighty" alternation from topic to topic by tenuous links such as rhyming or punning,[3] which are not necessarily present in logorrhea.


Logorrhea has been shown to be associated with traumatic brain injuries in the frontal lobe[4] as well as with lesions in the thalamus[5][6] and the ascending reticular inhibitory system[7] and has been associated with aphasia.[8] Logorrhea can also result from a variety of psychiatric and neurological disorders[7] including tachypsychia,[9] mania,[10] hyperactivity,[11] catatonia,[12] and schizophrenia.[13]


Excessive talking may be a symptom of an underlying illness and should be addressed by a medical provider if combined with hyperactivity or symptoms of mental illness, such as hallucinations.[14] Treatment of logorrhea depends on its underlying disorder, if any. Antipsychotics are often used, and lithium is a common supplement given to manic patients.[15]
