Geschwind syndrome
potential personality changes over time associated with temporal lobe epilepsy
Geschwind syndrome, also known as Gastaut–Geschwind syndrome or Waxman–Geschwind syndrome, is a group of behavioral phenomena evident in some people with temporal lobe epilepsy. It is named for one of the first individuals to categorize the symptoms, Norman Geschwind, who published prolifically on the topic from 1973 to 1984. There is controversy surrounding whether it is a true neuropsychiatric disorder. Temporal lobe epilepsy causes mild chronic changes in personality which are interictal (occurring between seizures) and slowly intensify over time. Geschwind syndrome includes five primary changes: hypergraphia, hyperreligiosity, atypical (usually reduced) sexuality, circumstantiality, and intensified mental life. Not all symptoms must be present for a diagnosis. Only some people with epilepsy or temporal lobe epilepsy show features of Geschwind syndrome.
Features
Hypergraphia
Hypergraphia is the tendency for extensive and compulsive writing or drawing, and has been observed in persons with temporal lobe epilepsy who have experienced multiple seizures. Those with hypergraphia display extreme attention to detail in their writing. Some such patients keep diaries recording meticulous details about their everyday lives.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Geschwind syndrome”, the useful work is to connect “potential personality changes over time associated with temporal lobe epilepsy” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 17, 2026. The linked authority identifier is Q4420119. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1973 and 1984.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
