ideational apraxia
The inability to conceptualize or sequence complex motor tasks despite understanding individual components.
Full Definition
Ideational apraxia is a specific form of apraxia characterized by the loss of ability to conceptualize, plan, and execute complex sequential motor actions, even when the individual can perform the component movements in isolation. This condition typically results from damage to the left parietal lobe and is distinguished from ideomotor apraxia by the presence of conceptual rather than motor execution deficits. Patients may understand what they want to do and retain individual motor skills but cannot organize these into coherent, goal-directed sequences.
Usage
Usage note: Provide specific examples of task breakdown and distinguish from ideomotor apraxia and general cognitive impairment.
