Three children of unilateral type I Duane’s retract ion syndrome (DRS), aged 8 years, 14 months and 2 years were confirmed by demonstration of absence of ipsilateral abducens nerves on 3D fast imaging employing steady-state acquisition (FIESTA...

OBJECTIVE Verbal apraxia is a neurologically based motor planning speech disorder of unknown etiology common in autism spectrum disorders. Vitamin E deficiency causes symptoms that overlap those of verbal apraxia. Polyunsaturated fatty acids in the cell membrane are vulnerable to lipid peroxidation and early destruction if vitamin E is not readily available, potentially leading to neurological ...

INTRODUCTION Existing literature suggests that the presence or absence of apraxia and associated parietal deficits may be clinically relevant in differential diagnosis of dementia syndromes. AIM This study investigated the profile of these features in Alzheimer's disease (AD) and frontotemporal dementia (FTD) spectrum disorders, at first presentation. METHODS Retrospective case note analysi...

This study aimed to verify the existence of a double aphasia/apraxia dissociation. Apraxic patients without aphasia and aphasic patients without apraxia were included in a consecutive series of patients with cortical or subcortical CT documented vascular lesions in the left hemisphere. Of 699 patients, 10 were found to be apraxic but not aphasic and 149 aphasic but not apraxic. These findings i...

Bipedal locomotion and fine motility of hand and larynx of humans introduced musculoskeletal adaptations, new pyramidal, corticostriatal, corticobulbar, nigrostriatal, and cerebellar pathways and expansions of prefrontal, cingular, parieto-temporal and occipital cortices with derived new brain capabilities. All selectively degenerate in aged homo sapiens following 16 syndromic presentations: (1...

BACKGROUND Corticobasal syndrome (CBS) is characterized by multifaceted motor system dysfunction and cognitive disturbance; distinctive clinical features include limb apraxia and visuospatial dysfunction. Transcranial magnetic stimulation (TMS) has been used to study motor system dysfunction in CBS, but the relationship of TMS parameters to clinical features has not been studied. The present st...

OBJECTIVE This aim of this study was to determine the reliability and validity of an established ideomotor apraxia test when applied to a Turkish stroke patient population and to healthy controls. SUBJECTS The study group comprised 50 patients with right hemiplegia and 36 with left hemiplegia, who had developed the condition as a result of a cerebrovascular accident, and 33 age-matched health...

The literature on apraxia of speech describes the types and characteristics of phonological errors in this disorder. In general, phonemes affected by errors are described, but the distinctive features involved have not yet been investigated. Objective To analyze the features involved in substitution errors produced by Brazilian-Portuguese speakers with apraxia of speech. Methods 20 adults w...
