Which of the following is NOT a symptom of G-LOC?

Grand mal seizures are not a symptom of G-induced Loss of Consciousness (G-LOC). G-LOC typically results from high levels of gravitational force (G-force) acting on the body, which can lead to a temporary loss of consciousness due to insufficient blood flow to the brain.

The symptoms of G-LOC, such as grayout, blackout, and lightheadedness, are primarily related to the effects of G-force on blood circulation and oxygenation in the brain. Grayout refers to a temporary loss of vision or perception, while blackout signifies a complete loss of consciousness. Lightheadedness is often an early indication that an individual is experiencing increased G-forces and potential onset of G-LOC.

In contrast, grand mal seizures are characterized by convulsions and loss of consciousness due to abnormal brain activity, which is not directly caused by G-LOC. This distinction is crucial for pilots and aerospace personnel to understand, as recognizing the symptoms of G-LOC can lead to preventive measures and safer responses in high-G environments.
