Whether or not you wear a helmet you may suffer concussion in an
accident. There is an interesting discussion of the mechanism in the
current issue of the New England Journal of Medicine:

(free full text available).

"The brief loss of consciousness that characterizes concussion appears to
be the result of rotational forces exerted at the junction of the upper
midbrain and thalamus that cause transient disruption of the functioning
of the reticular neurons that maintain alertness." There a possibility
that wearing a helmet might increase rotational forces, in which case
concussion might be more likely.


Very worrying - think of the childen; in some places they must wear
these things by law!
