is that patients build up cognitive representations of the gestures. Their inaccuracy shows up independently from the motor actions used for expressing their content. Brass and Heyes note that the old literature on neurological patients with apraxia is usually neglected but themselves neglect both old and new studies on apraxia. These studies cast severe doubts on the postulated superiority of ...

Objectives: We report the first case of writing apraxia as the main presenting feature of a posterior communicating artery aneurysm. Cerebral aneurysm usually presents with visual impairment, nausea and vomiting, severe headache and loss of consciousness. Case report: A 58year-old man presented to the neurological department because of writing difficulty, which affected his work as an executive...

Purpose The purpose of this 2nd article in this supplement is to report validity support findings for the Pause Marker (PM), a proposed single-sign diagnostic marker of childhood apraxia of speech (CAS). Method PM scores and additional perceptual and acoustic measures were obtained from 296 participants in cohorts with idiopathic and neurogenetic CAS, adult-onset apraxia of speech and primary...

PURPOSE The purpose of this report is to demonstrate a rare clinical manifestation of apraxia eyelid opening related to a basal ganglia lesion. CASE REPORT In this study, we report a 91-year-old woman suffering from difficulty in eyelid opening after being treated for myocardial ischemia with dual antiplatelet medications. She could open her eyelid with fingers touching her forehead. Brain co...

This study evaluated whether apraxia can be understood as due to impaired motor representations or motor imagery necessary for appropriate object-use, imitation, and pantomime. The causal role of the left inferior parietal lobe (IPL), which is heavily implicated in apraxia, is also evaluated. These processes are appraised in light of the proposed ventro-dorsal sub-stream of the classic two visu...

Background: Neuroimaging studies of Childhood Apraxia of Speech (CAS) have not revealed any systematic macrostructural abnormalities. Further, no studies have investigated connectivity of sensory-motor circuitries subserving speech and their possible changes after intervention in children with CAS. The first aim of this preliminary study was to identify possible altered neural networks in child...
