Ideomotor apraxia: a study of initial severity

Acta Neurologica Scandinavica, 1987
This study investigated whether there are predictors for initial severity of ideomotor apraxia (IMA) in focal left-hemisphere vascular patients. One hundred and twenty-nine subjects were examined between 15 and 30 days post-onset. Twenty-five patients with bilateral lesions were also studied in order to delineate the role of the right hemisphere. Other

Callosal ideomotor apraxia in Alzheimer’s disease

Journal of Clinical and Experimental Neuropsychology, 2016
Impaired ability to perform skilled movements with the left upper limb in patients with corpus callosum injury has been well described (callosal apraxia) with some displaying spatial-temporal errors primarily in response to verbal commands (verbal callosal disconnection apraxia), with imitation, and when using actual tools (callosal ideomotor apraxia).

Cognitive representations of hand posture in ideomotor apraxia

Neuropsychologia, 2003
Ideomotor apraxia (IM) is a disorder of skilled action characterized by spatiotemporal errors in pantomiming object use and in using objects. Recent evidence suggests that at least some patients with IM may exhibit particular deficits in forming hand configurations appropriate for object use. Sirigu et al.

Motor Performance in Aphasia and Ideomotor Apraxia

Perceptual and Motor Skills, 1994
Motor performance in 11 patients with ideomotor apraxia, 11 with aphasia without such apraxia, and 11 normal controls was compared. These three groups were matched on age, sex, education, severity of aphasia, intelligence, and size of lesion. Measures of aiming, tapping, line-following, and steadiness developed by Schoppe in 1974 were used.

Ideomotor apraxia in patients with dementia of alzheimer type

Journal of Neurology, 1987
Ideomotor apraxia was checked in a carefully selected group of patients with Alzheimer's dementia, all in the mild stage of the disease. It was shown that ideomotor apraxia is not an early neuropsychological feature. When compared with other cognitive measures, the speed of deterioration of ideomotor apraxia appears to be particularly slow.

Selective deficit of praxis imagery in ideomotor apraxia

Neurology, 1997
We studied imagery for learned, skilled movements (praxis imagery) in a patient with severe ideomotor apraxia and intact language abilities. This patient, who made predominantly spatial and movement errors when performing transitive movements demonstrating the use of tools (transitive gestures), was also impaired in her ability to answer imagery ...

Error Types in Ideomotor Apraxia: A Qualitative Analysis

Brain and Cognition, 1994
Seventeen brain-damaged subjects with dominant hemisphere pathology and 24 matched control subjects were asked to perform simple familiar gestures under four conditions: (1) verbal command (pantomime), (2) imitation, (3) with the actual object, and (4) verbal command a second time. The subjects subsequently watched a video of an actor performing simple

Ideomotor Apraxia: Behavioral Dimensions and Neuroanatomical Basis

Brain and Language, 1997
Ideomotor apraxia, disordered movement execution to command, commonly follows left-hemisphere damage, implying left-hemisphere dominance for certain kinds of movements. To delineate this dominance we used different command modalities to elicit meaningful movements and tested imitation of nonsense movements.

RECOVERY FROM IDEOMOTOR APRAXIA

Brain, 1987
In this study we investigated whether there are predictors for recovery from ideomotor apraxia (IMA) in patients with focal left hemisphere vascular lesions. Recovery was followed in 26 patients, first examined between 15 and 30 days postonset. They were apraxic at the first examination and had a second (and in some cases, a third) neuropsychological ...

Ideomotor limb apraxia in Huntington's disease

Journal of Neurology, 2008
Ideomotor limb apraxia is the disturbance of planning and of execution of motor activity,which is not caused by a dysfunction of the motor or sensory nervous system. Apraxia is a diagnostic criterion in dementialike Alzheimer's disease. However, this symptom may also occur in dementia with subcortical lesions like Huntington's disease (HD), a ...
