oral apraxia meaning
A group of cognitive disorders characterized by the inability to perform previously learned skills that cannot be attributed to deficits of motor or sensory function. The two major subtypes of this condition are ideomotor (see APRAXIA,IDEOMOTOR) and ideational apraxia,which refers to loss of the ability to mentally formulate the processes involved with performing an action. For example,dressing apraxia may result from an inability to mentally formulate the act of placing clothes on the body. Apraxias are generally associated with lesions of the dominant PARIETAL LOBE and supramarginal gyrus. (From Adams et al.,Principles of Neurology,6th ed,pp56-7)
- Both manual and oral apraxia were related to increasing severity of stroke.
- Oral apraxia was related with an increase in age at the time of the stroke.
- The Copenhagen Stroke Study, which is a large important study published in 2001, showed that out of 618 stroke patients, manual apraxia was found in 7 % and oral apraxia was found in 6 %.
