Which of the following statements is NOT true regarding somnambulism (sleep walking)?
Show Hint
Sleepwalkers perform complex coordinated acts, not low-level movements.
Updated On: Jun 23, 2026
- Sleep walking
- Patient consciousness is preserved
- Disorder of sleep arousal
- Low level motor skill or function is present
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Identify the disorder first. Sleep walking, or somnambulism, is a non-REM disorder of arousal that emerges from deep slow-wave sleep, and amnesia for the event is typical.
Step 2: Pin down the behaviour. The hallmark is that the patient carries out elaborate, coordinated actions such as walking, dressing, rearranging objects or driving, which require high-level motor function, not a reduced or minimal one.
Step 3: A negatively worded stem asks for the one wrong claim. Saying that only low level motor skill is present contradicts the complex automatisms that define the condition, so that is the false statement.
Step 4: Confirm the rest fit, and select the inaccurate option.
\[\boxed{\text{Low level motor skill or function is present}}\]
