We randomly assigned 33 patients with left hemisphere stroke, limb apraxia, and aphasia to an apraxia or a control (aphasia) treatment group. Before and after each treatment, patients underwent a comprehensive neuropsychological testing battery and a caregiver evaluation of patient's activities of daily life (ADL) independence. Apraxia severity was related with ADL independence. Control (aphasi...

purpose: to determine the distribution of oculomotor, abducens, and trochlear nerve palsies in diabetic patients with ocular nerve palsy. methods: this study was performed on all diabetic patients who referred to ophthalmology and neurology clinics at yazd medical science university because of ocular palsy from march 2004 to october 2005. signs and symptoms of the disorder were evaluated. resul...

Apraxia is classically defined as difficulty performing learned, skilled gestures. In this review, we describe the range of motor impairments classified as apraxia, focusing on ideomotor limb apraxia. We present several prominent models of praxis to explain the variety of difficulties seen in patients with apraxia. We also discuss the large-scale frontal-parietal-basal ganglia network thought t...

Ideomotor limb apraxia, a disorder of goal-directed movement, has been attributed to lesions in the frontal and parietal lobes, but the role of subcortical structures is less certain. In order to determine its prevalence in a disorder affecting the basal ganglia and corticostriatal connections, we examined imitation of hand gestures in Huntington's disease (HD) patients. We also assessed the re...

BACKGROUND cerebral multi-infarct states may lead to gait disorders in the absence of cognitive impairment. Where these gait disorders occur in the absence of neurological signs they have been termed gait apraxia or more recently higher-level gait disorders. In this paper we hypothesise three main types based on presumptive sites of anatomical damage: (a) Ignition Apraxia, where damage is predo...

Background Primary progressive apraxia is a rare form of apraxia in the absence of dementia which develops insidiously and is slowly progressive. Most reports of patients with apraxia also describe coexisting aphasias or involve additional apraxias with affected speech, usually in the setting of neurodegenerative diseases such as corticobasal degeneration, Alzheimer's disease or frontotemporal ...

Limb apraxia, a disorder of higher order motor control, has long been a challenge for clinical assessment and understanding (Leiguarda and Marsden, 2000). The deficits originally described in limb apraxia (Liepmann, 1920) have been classified by the nature of the errors made by the patients leading to, namely, ideational and ideomotor apraxia. The dual stream hypothesis (Goodale and Milner, 199...
