Polar T3 syndrome

Polar T3 syndrome is a condition found in polar explorers, caused by a reduction in levels of the thyroid hormone T3.[1][2] Its effects include forgetfulness, cognitive impairment and mood disturbances. It can exhibit itself in a fugue state known as the Antarctic stare.[3][4][5]

It is regarded as one of the contributory causes of winter-over syndrome.[3]
