A cerebral contusion is a type of brain injury that occurs when the brain is bruised due to a direct impact or trauma. This can happen during accidents, falls, or sports injuries. The injury leads to bleeding and swelling in the brain tissue, which can disrupt normal brain function. Symptoms of a cerebral contusion may include headaches, confusion, dizziness, and difficulty with coordination. In severe cases, it can lead to loss of consciousness or seizures. Diagnosis typically involves imaging tests like a CT scan or MRI to assess the extent of the injury and guide treatment.
