Sexual dysfunction in patients with brain lesions and encephalopathies

Sexual impairment is common after a traumatic brain injury. Both decreased and increased sexual desire have been reported. In women endocrine abnormalities are the most sensitive predictors of sexual dysfunction (Hibbard et al 2000). In males both impotence and retarded ejaculation have been reported (Meyer 1955, Kreutzer & Zasler 1989). This may in part be dependent upon post-traumatic anterior pituitary dysfunction (Agha et al 2004). Hypersexuality or altered sexual preference may sometimes follow frontal brain injury (Miller et al 1986) even leading to sex offending (Simpson et al 1999).

Lesions of the frontal and temporal lobe lead more often to sexual problems than lesions of the parieto-occipital part of the brain (De Morsier & Gronek 1972). Bilateral lesions of the anterior temporal regions may result in hypersexuality as in the Klüver-Bucy syndrome (Gerstenbrand & Lücking 1971, Oliveira et al 1989, Hayman et al 1998). Pansexuality, that is sexual drive directed not towards human beings but also towards animals and inanimate objects is sometimes a feature.
