Amygdalohippocampectomy is a surgical procedure for the treatment of
Amygdalohippocampectomy is used only when all other treatment options have failed to resolve the epilepsy. It is also used to cure severe aggression, and anxiety usually as a last resort treatment. It is an effective treatment for most patients. However, possible adverse side effects include impaired memory, dangerous risktaking behaviours, and defects in visual perception.
Procedure
The amygdalohippocampectomy is indicated when the focal point of the seizures can be anatomically localized to the hippocampus and amygdala. Normally, to be considered for this procedure, one must either have failed all first-line treatments for epilepsy, or if all therapy fails for severe aggression and anxiety. [3]
The selective amygdalohippocampectomy will remove only the offending portions of the hippocampus and amygdala.
Statistics and side effects
Of 376 patients who had the amygdalohippocampectomy procedure performed, compared to other types of temporal lobe resections, two thirds of this population were reported free of disabling seizures.[5] Some patients report defects in visual perception[6] and impaired memory function.[7] Almost all of them reported not feeling as much fear as before, hence inducing the risk-taking behaviour. It can also cause behavioural aggression, and can lower the effects of anxiety and Asperger’s Syndrome.
