Final answer:
Apraxia is a neurological disorder that inhibits the ability to carry out tasks or movements on command despite understanding the request and having the physical capability to do so. It often occurs due to damage to brain regions involved in motor planning.
Step-by-step explanation:
A psychomotor defect in which the proper use of an object cannot be carried out is called apraxia. Apraxia is a neurological disorder characterized by the inability to perform tasks or movements when asked, even though:
- The request or command is understood.
- The individual is willing to perform the task.
- The muscles needed to perform the task are physically able to do so.
Apraxia often results from damage to the brain regions that coordinate motor planning and execution, such as the frontal and temporal lobes. This damage can be due to a stroke, traumatic brain injury, or neurodegenerative diseases. Praxis in a neurological exam refers to the act of doing something using ready knowledge or skills in response to verbal instruction. Conversely, aphasia involves losses of language and speech functions, which presumably would not directly lead to an inability to use objects properly.
