What are common complications associated with traumatic brain injury (TBI)?

The answer is focused on specific medical complications that can arise following a traumatic brain injury (TBI). Seizures are a common complication due to altered brain function after trauma, which can lead to abnormal electrical activity. Hydrocephalus, or the accumulation of cerebrospinal fluid in the brain’s ventricles, can occur due to damage in the brain's structures that regulate fluid flow. Infections are a risk especially if the injury involves an open wound or if there is a hospital-acquired infection during the course of treatment. These complications can significantly impact recovery and may require additional interventions or treatments.

The other options mention symptoms and conditions that are indeed associated with TBI, such as cognitive and emotional issues, sensory impairments, and other challenges like sleep disturbances. However, they do not specifically highlight the acute physiological complications that are more directly linked to the immediate aftermath of brain injuries in a medical context.
