Hello. Thanks for asking from HCM. I can understand your concern. Social difficulties could be due to brain injury, genetic defect, poor social skills, brain infection, hypoxic or metabolic damage to brain. To reach upto some conclusion, your all symptoms, higher mental function and neurological system need evaluation. Only then it can be confirmed how much damage and social difficulties you are having. Then it should be evaluated by investigations like MRI brain, functional MRI brain. Regarding your question whether your poor social skill due to trauma, the fall from such height causing dent in skull may or may not cause injury to frontal lobe of brain and thus poor social skills. It can only be confirmed by MRI brain. Damage to frontal lobe on dominant side (usually left side brain) can cause social difficulties. MRI brain can show gliosis or cyst or diffuse cerebral atrophy in brain suggesting old injury in brain. Treatment of old brain injury is only symptomatic.
