Perseveration
 |
Look up perseverate in Wiktionary, the free dictionary. |
Perseveration is the repetition of a particular response, such as a word, phrase, or gesture, despite the absence or cessation of a stimulus, usually caused by brain injury or other organic disorder.[1] If an issue has been fully explored and discussed to a point of resolution, it is not uncommon for something to trigger the reinvestigation of the matter. This can happen at any time during a conversation. This is particularly true with those who have had traumatic brain injury.
Several researchers have tried to connect perseveration with a lack of inhibition; however, this connection could not be found, or was small.[2][3]
Perseveration may also refer to the obsessive and highly selective interests of individuals on the autism spectrum. This term is most connected to Asperger syndrome.
