Atypical sexuality
People with Geschwind syndrome reported higher rates of atypical or altered sexuality. In approximately half of affected individuals hyposexuality is reported. Less commonly, cases of hypersexuality have been reported.
Circumstantiality
Individuals who demonstrate circumstantiality (or ''viscosity'') tend to continue conversations for a long time and talk repetitively.
Intensified mental life
Individuals may demonstrate an intensified mental life, including deepened cognitive and emotional responses. This tendency may pair with hypergraphia, leading to prolific creative output and a tendency toward intense, solitary pursuits.
