Methylphenidate in amytal-resistant mutism.
Methylphenidate eliminated mutism in a catatonic schizophrenic after Amytal had failed. Response permitted an adequate clinical evaluation and temporary resumption of eating, self-care and sociability. This suggests that methylphenidate has a useful role in the clinical evaluation of the mute patient who fails to respond to Amytal and that 2 psychopharmacological varieties of catatonic mutism may exist.
