Which statement best reflects behavior in individuals with traumatic brain injury?

• A. People with TBI have erratic behavior and sudden turns not within their control
• B. They always act predictably
• C. They never experience rapid changes in behavior
• D. Their behavior remains constant

Answer: (A)

Traumatic brain injury disrupts the brain systems that regulate behavior, emotion, and self-control. Because of this disruption, behavior can be variable and may include sudden shifts or actions that the person cannot fully control. This leads to erratic behavior and rapid changes in how someone behaves, even within short periods. Factors like fatigue, pain, medications, or medical issues can further influence these fluctuations, making the pattern less predictable rather than constant. Although some moments may appear calm, the overall tendency after a TBI is toward volatility rather than steady, predictable behavior.
