Limb apraxia in acute ischemic stroke: A neglected clinical challenge?

Limb apraxia in acute ischemic stroke: A neglected clinical challenge? Neurocase. 2013 Jan 4; Authors: Schell C, Suchan J, Himmelbach M, Haarmeier T, Borchers S Abstract Symptoms of limb apraxia and executive dysfunctions are currently not explicitly considered by the National Institutes of Health Stroke Scale and, thus, not routinely tested by clinicians in the acute care of patients with suspected stroke. Neuropsychological testing, clinical examination, MRI, and functional magnetic resonance imaging (fMRI) were performed in a right-handed patient with acute onset of left-sided sensorimotor hemiparesis due to a right hemisphere ischemic stroke. Deficits in the execution of meaningless and meaningful gestures were not detected properly on initial clinical examination but were revealed later on through neuropsychological testing. Instead, the patient's inability to respond to specific instructions in the acute care setting was mistaken to reflect severe deficits in auditory comprehension. fMRI revealed right-hemispheric localization of language in the right-handed patient. We suggest including a bedside test for limb apraxia symptoms in acute clinical care of stroke patients. The distinction between deficits in limb praxis and impairments of language can be complicated owing to the common hemispheric co-localization of the two functions.
