Some signs and symptoms of concussion
can vary dramatically from case to case. Loss of consciousness is not an
indicator of a concussion. Some signs and symptoms include; confusion, amnesia,
disorientation, vacant stare, inability to focus, delayed verbal and motor
responses, slurred speech, balance disruption, nausea/vomiting, sensitivity to
light, headaches, dizziness, irritability, fatigue, anxiety, depression, and
sleep disturbances.
Often these signs and symptoms are
short-lived in nature and will usually spontaneously resolve with 7-10 days. However,
in some cases the effects of concussion can be long lasting and persistent.
There are no structural changes to the
neurological system after a concussion, therefore standard neuroimaging studies
are incapable of detecting any disturbance.
Correct diagnosis and management of
concussion is vital for full recovery. The management of concussion is centered
around complete physical and mental rest until the acute symptoms resolve. A
graded return to daily activities and physical exertion is necessary to prevent
long term neurological effects.
