Brain, 1988
Ideational apraxia was investigated in 20 left brain-damaged patients with tests requiring the demonstration of how objects are used. On a multiple object use test the most frequent errors were those of omission, misuse and mislocation, while sequence errors were rare. Patients also failed on a single object use test, which showed a correlation of 0.85

Limb apraxia is an impairment in the ability to perform skilled, purposive limb movements as the result of neurological dysfunction. In right-handed individuals, limb apraxia is associated with left hemisphere lesions. This article reviews the subtypes and neuroanatomic correlates of limb apraxia, including limb kinetic apraxia, ideomotor apraxia ...

Gestural apraxia was first described in 1905 by Hugo Karl Liepmann. While his description is still used, the actual terms are often confusing. The cognitive approach using models proposes thinking of the condition in terms of production and conceptual knowledge. The underlying cognitive processes are still being debated, as are also the optimal ways to

The International Journal of Psychiatry in Medicine, 1992
A case is described in which a patient had pseudoneurological symptoms that were present only upon direct observation or when the patient was in clinical test situations. The differential diagnosis of apraxia is discussed as well as clinical suggestions for evaluating patients with suspected factitious 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.

Neurology, 1987
A 39-year-old right-handed woman suffered a ruptured pericallosal aneurysm. Serial MRI studies showed damage to the genu and most of the body of the corpus callosum but not the splenium. Both supplementary motor areas (SMA) appeared intact. We studied the patient's praxis performance at intervals over a 4-month period with a standardized battery.

WIREs Cognitive Science, 2001
The term apraxia refers to ‘higher level’ disorders of motor control. Apraxia differs from other motor symptoms of unilateral brain damage by the bilaterality of symptoms following unilateral lesions. Lesions causing apraxia are located predominantly in the left hemisphere and apraxia is frequently, although not invariably, associated with aphasia ...

Journal of Neurology, 1983
Ideational apraxia is a rare behavioural disturbance observed in patients with a lesion in the posterior part of the hemisphere dominant for language. The main feature is an impairment in carrying out sequences of actions requiring the use of various objects in the correct order necessary to achieve an intended purpose. The syndrome cannot be explained

European Neurology, 1982
A case of 'palpatory' apraxia is reported. The apraxia was characterized by clumsiness of the left hand in the manipulation of objects with preservation of power and finger motility in visual imitation. From the analysis of the patient's behavior and associated sensory findings, a defect of a higher-order sensory system was speculated as a basis of ...

Abstract The motor system, which includes the corticospinal system together with motor neurons, is capable of directing muscles to make an almost infinite variety of movements. To perform skilled movements, the brain must acquire the knowledge through experience to program the motor system, so that these movements can be made correctly ...
