Concussion



A concussion is a status condition caused by having the head critically crippled in combat.

Fallout 3 and Fallout: New Vegas
Having a concussion will reduce overall accuracy and give a -4 to Perception. In addition, the screen will intermittently get fuzzy and a ring will be heard through the speakers. It is unknown if enemies really undergo a concussive state when they have their heads crippled.

As with the crippling any body part, targets will momentarily pause to clutch their head.

Using a stimpak, sleeping, visiting a doctor, using My First Infirmary (if purchased for the residence), or through some other means relieving the crippled head will remove the effect and restore the Perception.
