What Is Space Dementia?
Space dementia is a disease characterized by mental instability and irrational behavior brought on after the individual enters outer space.
NASA has only seen mild cases of space dementia as of yet, and as a result some have suggested that the disease does not actually exist. However, due to the small sample size of people who have spent time in outer space, experts have not completely ruled out the existence of the disease. Regardless, there is a protocol set up for dealing with a psychological emergency in space. Astronauts are instructed to bind the stricken person's wrists and ankles with duct tape, restrain their torso with bungee cords and administer strong tranquilizers.
