Tuberous sclerosis in the aetiology of the so-called idiopathic epilepsies and psychoses.

Ten suspected cases of tuberous sclerosis seen over a period of 4 1/2 years are described. Investigations were carried out in a general practice setting. The place of tuberous sclerosis in the so-called idiopathic and functional psychoses is discussed and an additional aetiological mechanism is postulated. A skin test is suggested to determine the presence of this condition in a shorter period of time.
