Motor Learning in Ideomotor Apraxia

International Journal of Neuroscience, 1989
Using Luria's motor sequence test, we studied the learning ability of 34 right-handed patients with unilateral hemisphere lesions. Patients with ideomotor apraxia needed 4 to 6 trials in the test, while the remainder needed only 1 or 2. Ideomotor apraxics also required more time to complete the test.

Ideomotor apraxia in Alzheimer's disease

Acta Neurologica Scandinavica, 2009
Ideomotor apraxia, tested on verbal command and by imitation, was checked in 23 patients suffering from dementia of Alzheimer's type of different severity and in 17 age-matched controls. A significant deterioration of ideomotor praxis could be shown even in mild dementia.

Two forms of ideomotor apraxia

Neurology, 1982
Destruction of parietal areas containing visuokinesthetic motor engrams, where motor acts may be programmed, should be distinguishable from apraxia induced by disconnection of these parietal areas from frontal motor areas. Destruction should result in inability to distinguish well-performed from poorly performed movements, whereas disconnection should ...

Sensorimotor Learning in Ideomotor Apraxia

Perceptual and Motor Skills, 1995
Sensorimotor learning ability in patients with ideomotor apraxia was investigated, using as subjects, eight patients with ideomotor apraxia, 8 with aphasia without ideomotor apraxia, and 8 normal controls. The aphasia, apraxia, and normal control groups were matched for age, sex, and education.

Ideomotor Apraxia And Functional Ability

Cortex, 2007
The impact of ideomotor apraxia (IMA) on functional ability has been a relatively neglected topic in research. This has been due to the continued focus on performance on gesture imitation and pantomime of tool-use, together with widespread acceptance of anecdotal evidence that IMA has no effect when directly manipulating objects.

Ideomotor Apraxia in Huntington's Disease

Archives of Neurology, 1991
The pattern of movement errors in ideomotor apraxia suggests an abnormality in selection and sequencing of component movements. Individuals with Huntington's disease were evaluated prospectively for the presence of apraxia, and aspects of motor and cognitive function were correlated with apraxic errors. Based on a conservative apraxia rating, ideomotor

LESION SIZE AND LOCATION IN IDEOMOTOR APRAXIA

Brain, 1984
Lesion size correlated positively with the severity of apraxia in the acute (one month) and chronic (one year) stage in 177 stroke patients, but accounted for only 25 per cent of the variance of the apraxia scores. Apraxia was measured on a standardized battery and defined in relation to normal controls. Lesions visualized by CT were traced objectively

Ideomotor Apraxia: a Call to Action

Neurocase, 2001
Although ideomotor apraxia (IM) has been a topic of investigation since the early 20th century, progress in studying the disorder has been hindered by important (and sometimes unarticulated) differences in the underlying theoretical models of various investigative groups.

Defective motor learning in ideomotor apraxia

Neurology, 1975
Liepmann suggested that the left hemisphere contained the engrams for motor sequences. Other investigators have suggested that ideomotor apraxia may be caused by either a destruction of these engrams or a disconnection of these engrams from motor systems in the nondominant hemisphere.

NEUROPSYCHOLOGICAL AND NEUROANATOMICAL DIMENSIONS OF IDEOMOTOR APRAXIA

Brain, 1992
Fifty-five right-handed men with left hemisphere stroke were systematically investigated for ideomotor apraxia of various body parts. Standardized aphasia and apraxia examinations in all cases, and appropriately timed CT in 28 cases, were used for analysis of psychological and anatomical properties of ideomotor apraxia. It is not possible to ignore the
