TBIs often have very serious effects on an individual’s health. Even a mild TBI can leave you with a severe headache, nausea, fatigue, dizziness, lost balance, and issues with your concentration and memory.
More serious TBIs can lead to
Seizures or convulsions
Loss of coordination
Vertigo
Infections
Paralysis
Tinnitus (ringing in the ears)
Note that these are only examples of the more serious symptoms associated with TBIs. Some people fall into a coma after a TBI or face serious problems with speech, memory, or mood changes after a blow to the head.
