Reversible "locked-in" syndromes.

Two young patients are described who made good recoveries from a "locked-in" syndrome presumed to be due to ventral pontine ischemia. The first patient recovered completely from quadriplegia and mutism. In the second patient the only permanent sequellae were slight dysarthria and mild spasticity. Since patients may recover nearly completely from a "locked-in" syndrome, aggressive supportive therapy seems justified during the initial weeks or months.
