Studies in nonhuman and human primates have demonstrated that sound-producing actions are mapped on the same mirror circuits that are activated during the visual recognition and execution of actions [1-12]. However, no causative link between the auditory recognition and execution of actions has been provided thus far. Here, we sought to determine whether patients with apraxia, who are by defini...

Background: Dyslexia prevalence, diagnosis, risk factors and even awareness are quite uncertain in Egypt. One of the limitations in dyslexia evaluation for Arabic readers is the absence of rapid easy diagnostic test. The only available Arabic Reading Test for dyslexia is lengthy and only applicable at age 9-10 year where it is late for treatment of dyslexia. Objective: The objective of this stu...

Developmental apraxia of speech is a disorder of phonological and articulatory output processes. However, it has been suggested that perceptual deficits may contribute to the disorder. Identification and discrimination tasks offer a fine-grained assessment of central auditory and phonetic functions. Seventeen children with developmental apraxia (mean age 8:9, years:months) and 16 control childr...

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...
