Crossed face apraxia

Upper and lower face apraxia: role of the right hemisphere.

The aim of this study was to evaluate face apraxia in left- and right-hemisphere-damaged patients both in the acute and chronic stage of their disease. Two newly devised tests that assess movements of the upper and lower face districts were employed. On the whole, the proportion of left-hemisphere-damaged patients showing face apraxia were 46 and 68% for upper and lower face, respectively. A su...

Progressive Crossed-Apraxia of Speech as a First Manifestation of a Probable Corticobasal Degeneration

We present the longitudinal neurolinguistic, neuropsychological and neurologic follow-up of a 64 y.o. right-handed woman, who developed progressive apraxia of speech (PAOS), followed by peripheral agraphia then a left corticobasal syndrome (CBS). Neuroimaging (CT, MRI and FDG-PET) unequivocally showed progressive right hemispheric atrophy and hypometabolism. This particular evolution first conf...

Apraxia.

Humans need to perform skilled movements to successfully interact with their environment as well as take care of themselves and others. These important skilled purposeful actions are primarily performed by the forelimb, and the loss of these skills is called apraxia. This review describes the means of testing, the pathophysiology, and the clinical characteristics that define five different gene...

Crossed Transcortical Motor Aphasia, Left Spatial Neglect, and Limb and Magnetic Apraxia Due to Right Anterior Cerebral Artery Infarction

Crossed aphasia refers to language disturbance due to right-hemisphere lesions in right-handed individuals, while magnetic apraxia is described as 'forced grasping and groping' caused by lesions in the contralateral frontal lobe. This is a case report of a 70-year-old right handed woman who suffered from crossed transcortical motor aphasia and left hand magnetic apraxia due to right anterior ce...
