Athymhormic syndrome

Encyclopedia : A : AT : ATH : Athymhormic syndrome

In 1982, Laplane and collaborators published cases of "loss of psychic self-activation"after bilateral lesions of the lenticular nucleus (in fact the pallidum). This is characterized, in absence of motor signs, by an absence of motion and also of thinking.Patients complain about a mental void or blank. This is accompanied by a little emotional concern (athymhormy) and by compulsive syndroms. After stimulations from the outside the subject is able to move normally. This is evocative of the paradoxal hyperkinesia observed in akinesia. The syndrom was also called psychic akinesia.
