Sensory loss

It's usually temporary, and the most common sense to be lost is sight.

Maybe the whumpee was caught on a explosion, or it's the effect of some drug or chemicals. Or perhaps, a symptom of a disease, or even a spell.

The Mentalist


 * 1x16: Patrick Jane (Simon Baker) is caught by the blast of an explosion, and is temporarily blind. He stays like this the entire episode, and discharging himself from the hospital doesn't help. He bumps into some things, faints, and in the end, has to get away from the killer and (try to) drive a car.
