<unk>  are ways to classify brain<unk> :<unk><unk>  occurs in a specific location, while<unk><unk>  occurs over a more widespread area. It is common for both<unk>  and<unk>  damage to occur as a result of the same event; many traumatic brain<unk> es have aspects of both<unk>  and<unk><unk> .<unk> <unk> es are commonly associated with an<unk>  in which the head strikes or is struck by an object;<unk> <unk> es are more often found in acceleration/deceleration<unk> es, in which the head does not necessarily contact anything, but brain tissue is damaged because tissue types with varying densities accelerate at different rates. In addition to physical trauma, other types of brain<unk> , such as stroke, can also produce<unk>  and<unk> <unk> es. There may be primary and secondary brain<unk>  processes.
