LOC commands (ability to follow simple instructions)

These components are essential in understanding a patient’s alertness and cognitive function immediately after stroke onset.

Typical Questions and Expected Answers in Group A

Understanding the answers to Group A questions requires familiarity with the scoring criteria used by clinicians. Here’s a simplified overview: 1. Level of Consciousness (LOC)

Score 0: Alert
Score 1: Not alert but arousable by minor stimulation
Score 2: Not alert, requires repeated stimulation to attend
Score 3: Unresponsive

2. LOC Questions (Orientation)

Patients are asked to state the current month and their age.
Score 0: Answers both correctly
Score 1: Answers one correctly
Score 2: Answers both incorrectly

3. LOC Commands

Patients are asked to open/close eyes and grip/release hand.
Score 0: Performs both tasks correctly
Score 1: Performs one task correctly
Score 2: Performs neither task

These answers allow clinicians to assign numeric values that reflect the patient’s neurological state. The cumulative score from Group A items contributes to the overall NIHSS, guiding clinical decisions.
