Causas:

Una conmoción cerebral puede darse cuando la cabeza golpea un objeto o un objeto en movimiento golpeó contra la cabeza.

Una conmoción cerebral puede resultar de una caída, actividades deportivas y accidentes automovilísticos. El movimiento significativo del cerebro (llamado discordante) en cualquier dirección puede provocar pérdida de la lucidez mental (quedar inconsciente). El tiempo que la persona permanezca inconsciente puede ser un indicio de la gravedad de la conmoción cerebral.


Conmoción cerebral
Sin embargo, las conmociones cerebrales no siempre implican una pérdida del conocimiento. La mayoría de las personas que tienen una conmoción cerebral nunca pierden el sentido. Usted puede tener una conmoción cerebral y no darse cuenta.
