A traumatic brain injury (TBI) can occur after a bump, jolt, or blow to the head or body that disrupts normal brain function. While some symptoms may be immediately noticeable, like loss of consciousness, confusion, headache, or dizziness, other symptoms can be more subtle and may develop hours, days, or even weeks after the injury.
Brain injuries can affect many areas of function, including thinking, emotions, behavior, communication, and physical abilities. Some less noticeable signs of a brain injury may include difficulty concentrating, memory changes, fatigue, sleep disturbances, or increased sensitivity to light or noise. Other symptoms may include changes in mood or behavior, such as increased irritability, anxiety, depression, impulsivity, or difficulty managing emotions.
Because symptoms can vary widely depending on the severity and location of the injury, it’s important to seek medical guidance if changes occur after a head injury, even if symptoms seem mild. Early evaluation and appropriate treatment, including rehabilitation when needed, can help support recovery and improve function.
