Update on apraxia.

چکیده
Apraxia is classically defined as difficulty performing learned, skilled gestures. In this review, we describe the range of motor impairments classified as apraxia, focusing on ideomotor limb apraxia. We present several prominent models of praxis to explain the variety of difficulties seen in patients with apraxia. We also discuss the large-scale frontal-parietal-basal ganglia network thought to underlie praxis. In this context, we highlight the common occurrence of limb apraxia in corticobasal degeneration, a neurodegenerative condition characterized by frontal, parietal, and basal ganglia disease.

Apraxia: Review and Update
Praxis, the ability to perform skilled or learned movements is essential for daily living. Inability to perform such praxis movements is defined as apraxia. Apraxia can be further classified into subtypes such as ideomotor, ideational and limb-kinetic apraxia. Relevant brain regions have been found to include the motor, premotor, temporal and parietal cortices. Apraxia is found in a variety of ...
متن کاملSeverity and Co-occurrence of Oral and Verbal Apraxias in Left Brain Damaged Adults
Objective: Oral and verbal apraxias represent motor programming deficits of nonverbal and verbal movements respectively. Studying their properties may shed light on speech motor control processes. This study was focused on identifying cases with oral or verbal apraxia, their co–occurrences and severities. Materials & Methods: In this non-experimental study, 55 left adult subjects with left b...
متن کاملThe nature of apraxia in corticobasal degeneration.
Although apraxia is one of the most frequent signs in corticobasal degeneration, the phenomenology of this disorder has not been formally examined. Hence 10 patients with corticobasal degeneration were studied with a standardised evaluation for different types of apraxia. To minimise the confounding effects of the primary motor disorder, apraxia was assessed in the least affected limb. Whereas ...
متن کاملUpper and Lower Face and Ideomotor Apraxia in Patients with Alzheimer’s Disease
INTRODUCTION Apraxia of face movement in Alzheimer's disease (AD) has been rarely investigated. This study aimed at investigating the frequency of lower (mouth, tongue and throat) and upper (eyes and eyebrows) face apraxia, in AD and its relationship with limb apraxia and severity of dementia. METHODS Fifty seven patients with AD were tested with a new standardised test of face apraxia includ...
متن کاملAssessment of apraxia: inter-rater reliability of a new apraxia test, association between apraxia and other cognitive deficits and prevalence of apraxia in a rehabilitation setting.
OBJECTIVE To investigate the inter-rater reliability of a new apraxia test. Furthermore to examine the association of apraxia with other neuropsychological impairments and the prevalence of apraxia in a rehabilitation setting on the basis of the new test. DESIGN Cross-sectional cohort study, involving 100 patients with a first stroke admitted to a rehabilitation centre in the Netherlands. M...
