Tachypsychia
A neurological condition that alters the perception of time, usually induced by physical exertion, drug use, or a traumatic event. For someone affected by tachypsychia, time perceived by the individual either lengthens, making events appear to slow down, or contracts, objects appearing as moving in a speeding blur.
Origin
The term derives from Ancient Greek tachos (swiftness) and psuchè (life breath, spirit, soul, mind), translating as "rapid mind" or "fast psyche." The exact origin is uncertain, though the condition has been documented in psychology and neurology literature describing altered time perception during extreme stress, physical exertion, or trauma. The Greek etymology captures the subjective experience: while external time remains constant, the mind's internal processing accelerates or decelerates, distorting temporal perception.
