abstract: The historical evolution of P.M.S. nosography is pointed out, and his clinical features are exposed, mainly on the ground of the study performed by Lob and Coll., for the Tenth Marseilled Colloquium. Stress is laid upon the onset age of P.M.S., making reference to a review of 133 cases previously reported in the literature. Two paradigmatic cases are reported, selected between six P.M.S. observations we collected, and electroclinically investigated, from 1972 to 1975: a woman aged 34 who was suffering from P.M. and G.M. seizures since she was 12-years old, and also had some other P.M.S. episodes during past years; a woman aged 45 who suffered from a sudden P.M.S. attack, during a febrile illness: it seemed that it was the first occurrence, but an accurate catamnestic search suggested that previous P.M.S. manifestations had probably occurred during the infancy. Finally P.M.S. nosography is discussed for what concerns the variable features emphasized by our observations, the correlation between P.M. and P.M.S., and the problem of P.M.S. as the sole epileptic phenomenon.
