Parietal lobe somatosensory damage may impair recovery and interfere with rehabili tation. Ten patients with CT evidence of parietal lobe stroke with discriminative sen sory dysfunction (tactile extinction and astereognosis) and impaired motor control (tactile apraxia and optic ataxia) were studied. Functional status was graded by the Rankin Scale at 3 and 6 months after onset of stroke. Patients with this subtype of stroke showed statistically significant improvement at 3 and 6 months. Patients with left brain stroke had a better functional outcome. Age, gender, size of infarct, and lo cation of infarct were not useful as predictors of outcome. In one-half of the patients studied there was a 25 percent to 50 percent reduction in neurologic deficits at 6 months follow-up.
