Mental Status Exam

Assessing Praxis



    • How to Assess

    • Gestures - ask the patient to mirror both meaningful (waving) and non-meaningful (hand positioning) movement.
    • Fist-palm-edge - ask the patient to place a fist onto the table (or onto their knee), and then their palm, and then the edge of their hand. Begin by performing these tasks with the patient and then watch as they attempt them alone.
    • Ask the patient to demonstrate how they would use a hammer, comb or scissors.


  • The inability to perform movements despite intact motor and sensory systems.
    • Causes of Apraxia

    • Frontotemporal dementia
    • Alzheimer’s disease
