Concussion is the simplest form of brain trauma. There are no organic damages to the brain in cases of concussion, only a temporary functional disorder. It is usually indicated with headache, amnesia for the causative event, temporary loss of or disturbed consciousness, nausea, dizziness, etc.
Symptoms tend to weaken and disappear in a few days.
Occurrence of new symptoms or worsening of the present ones indicates more severe trauma than a simple concussion. Seizure should be taken very seriously and further diagnostic procedures (MRI, EEG…) are required to identify the exact cause.
