A traumatic brain injury or TBI can occur due to an impact or jolt of a car accident. TBIs can have a variety of complications, including that you may suddenly feel different from the person that you used to be. You may experience mood swings, outbursts or other emotional symptoms.
According to Brainline, injuries to specific areas of the brain can cause behavioral changes.
Emotional changes are common with TBI. Given the variation of injuries, there are also a variety of ways that your emotions may change. You may become more negative, less tolerant and find yourself unable to adapt or practice flexibility. It is also common to experience depression or anxiety symptoms.
On the other hand, you may become more apathetic and feel like the TBI muted your personality. To others, it may appear as though you are emotionless. Other emotional changes include mood swings, where you feel as though your emotions can turn quickly. For instance, you may feel deep sadness and then unpredictably feel excitement and happiness directly after. These feelings may have little to do with your circumstances or your environment.
You may go from a motivated person to someone who lacks initiative. Your productivity could suffer due to your inability to stay motivated. If your frontal lobe suffers an injury, you may become more impulsive. The frontal lobe regulates your self-control. It is the area of your brain that stops you from making rash decisions or acting recklessly. In addition to mood swings and verbal outbursts, you may also become more physical with others or your surroundings.
