The symptoms of a brain injury vary because of the complexity of the brain. The brain controls every single thing our bodies do, so there is a potential impact on every one of our functions! There could be physical impairments (e.g., poor balance, poor hand control, dizziness, double vision, etc.). There could be cognitive and communication impairments (e.g., poor attention, poor memory, word finding difficulty, poor organization, impulsivity, etc.) and emotional changes (e.g., difficulty controlling anger). In fact, 80-100% of individuals with a brain injury have cognitive-communication difficulties. Many of these difficulties can be subtle and go unnoticed for weeks or months.
