Which symptom is NOT typically associated with G-LOC?

• A. Visual grey-out
• B. Memory loss
• C. Full recovery within seconds
• D. Immediate pain

Answer: (D)

G-induced Loss of Consciousness (G-LOC) occurs when the body's blood flow is insufficient to maintain brain function during high levels of acceleration forces, commonly experienced in aviation or high-performance sports. Visual grey-out, memory loss, and full recovery within seconds are all typical symptoms associated with G-LOC. In the event of G-LOC, individuals often first experience a grey-out, where their vision fades to grey as they approach loss of consciousness due to a lack of blood flow to the eyes and brain. There may also be short-term memory loss regarding events just before the G-LOC occurs, as the brain is not adequately perfused during this episode. Fortunately, most individuals can regain full consciousness and cognitive function within seconds once the G-forces are reduced and normal blood flow is restored. In contrast, immediate pain is not a symptom typically associated with G-LOC. Rather than experiencing pain, individuals are likely to feel disoriented and may not register sensations during the episode, as consciousness is compromised. Thus, the absence of immediate pain when experiencing G-LOC distinguishes it from the other symptoms commonly noted.
