We examined the clinical characteristics of six right-handed patients who developed speech motor control disorders after human immunodeficiency virus(HIV)infection.They exhibited an ataxic dysarthria,characterized by irregular articulatory breakdowns in consonant and vowel timing;were slow in timed decision-making tasks;and had impaired procedural learning.Other aspects of the neurologic examination revealed signs of diffuse CNS involvement including action-intention tremors,ataxic gait,and release signs.None developed HIV-associated dementia during one year of followup. Motor speech control disorder appears to be related to a cerebellar function. |
