Apraxia in movement disorders.
The definition of apraxia specifies that the disturbance of performed skilled movements cannot be explained by the more elemental motor disorders typical of patients with movement disorders. Generally this does not present a significant diagnostic problem when dealing with 'higher-level' praxic disturbances (e.g. ideational apraxia), but it can be a major confound in establishing the presence o...
متن کاملDeconstructing apraxia: understanding disorders of intentional movement after stroke.
Impairments in praxic functioning are common after stroke, most frequently when the left hemisphere is affected. Several recent studies of apraxia after stroke have made advances in understanding the right hemisphere contribution to praxis, particularly for the performance of novel actions. Moreover, quantitative lesion analysis in stroke patients indicates the importance of cortical regions su...
متن کاملKinematic analysis of movement imitation in apraxia.
Accuracy of the final position and kinematics of movement were analysed during the imitation of meaningless gestures in patients with unilateral brain lesions who performed with the hand ipsilateral to the lesion and in control subjects. Controls imitated the gestures virtually without spatial errors. The kinematics of their movements was characterized by single-peaked and approximately bell-sh...
متن کاملNeuropathology in movement disorders.
This review concentrates on the definition and classification of degenerative movement disorders in which Parkinsonian symptoms are often prominent. The pathological spectrum and clinical manifestations of Lewy body disease are described, and associations with Alzheimer's disease and motor neuron disease are explored. A classification of pallidonigral degenerations is based on clinical features...
متن کاملMovement disorders in catatonia.
Catatonia is a complex neuropsychiatric syndrome characterised by a broad range of motor, speech and behavioural abnormalities. 'Waxy flexibility', 'posturing' and 'catalepsy' are among the well-recognised motor abnormalities seen in catatonia. However, there are many other motor abnormalities associated with catatonia. Recognition of the full spectrum of the phenomenology is critical for an ac...
