Sir, My son age 19 yrs, a bright 12 th class student in Jan 2009, faced a bike accident, fell on forehead, no external injury but forehead swelled. Loss memory for a few days. Consulted a neurologist at that time, he examined CT scan. He did not tell of any serious problem. My son wanted to take Pre Medical Test but the doctor advised to opt for easier courses. My son insisted on taking PMT. He passed 12th with good marks. Now seems very sad, orientation and motivation to studies and career has been lost. Forgets whatever he studies. Is it depression or the accident is showing up its effect after several months. What should I do.
