Language skills are demonstrated without evidence of agnosia, aphasia or apraxia.” Example of abnormal:l“The patient is alert and oriented to person and time, but is unable to identify the location, believing she is in her childhood home in Omaha. Correct registration of 3 obj

The patient correctly repeats the names of objects, without evidence of agnosia or aphasia. The patient is unable, however, to complete commands or purposeful actions and demonstrates difficulty completing written or verbal commands. Apraxia is suspected.
