Why Aggression, Irritability, and Depression Are Common After Brain Injury

Changes in or damage to the brain make emotional and behavioral issues common after a TBI.

Individuals showing aggressive or irritable behavior is also very common after brain injury--of various severities, whether it's mild, moderate, or severe. And some individuals just will become verbally aggressive and lash out, but some people will also become physically aggressive. We know that depression is certainly a risk factor for aggressive behavior, so it occurs more commonly when people are depressed, but it also is stemming from some of the areas of the brain that are injured. So, if you have injury to the front part, the prefontal cortex, the result of that is disinhibiting other areas of the brain. So you have disinhibition of other impulses. So, things that people may think about and not do without a brain injury, they will do without thinking after a brain injury.

Suffered a TBI in December of 2013 after falling to the ground during a seizure. My doctor's description was that I suffered a 'significant blow to my head'. Multiple skull fractures and brain bleeds. Many residual effects from the TBI. Fluctuating mood swings, insomnia, anxiety, and depression. Would medicinal marijuana be at all beneficial in alleviating any of these symptoms? Numerous medications have been tried and were not very successful.
