Explanation:
Detailed explanation-1: -Apraxia is inability to execute purposeful, previously learned motor tasks, despite physical ability and willingness, as a result of brain damage.
Detailed explanation-2: -Liepmann discussed three types of apraxia: melokinetic (or limb‐kinetic), ideomotor, and ideational.
Detailed explanation-3: -Ideomotor and ideational apraxia are higher motor disturbances at two different levels. In ideomotor apraxia the execution of simple and complex, meaningful and meaningless movements with the orofacial musculature and/or with the limbs, is impaired in a very distinct way, as has been described in detail.
