Suffering From Lack Of Interest In Family. Playing Only Video Games. Consulted Physicist. No Use. Suggest?

Question: My only son is 25yrs old. He is very intelligent. He was a scholar in his school days. He was given his first computer when he was in std-III. In latter part of the school he started drifting from studies and engaging in video games. He took addmission in BE. In college days, he only played and played. He was in the college for 5 yrs and could reach 3rd year. He dropped out 2yrs back. He then wanted to persue a training course. He joined it. For two months, when his laptop was not with him in the hostel, he performed well. He completed 8mths out of 20 mths and passed 3 subjects out of 7 subjects appeared. He did not study but appeared for the examinations. When asked why without preperation he appears, his answer is "to learn 2+2=4, I need not to study". After failing, his answer was "they don't know how to check the answer sheet". Now he is sleeping for 12hrs and playing/remaining on the net for rest 12hrs. This playing is mostly at night. We are struggling to serve food in odd hours. He is taking 2 meals a day. As long as he is not objected, he is merrily pulling on. The moment he is objected, he shows anger. He is using his anger as his shield. A week back, when I requested him to visit a physhiatrist, he answered "I don't require, you require it, had it been a civilised country like US, you were to be arrested by police for child abuse XXXXXXX I have never slapped him, his mother had done a few times when he was younger. He was over-protected, over-pampered. He tells, for our over protection he has no friend and that's why he is left with video games. His friends are all away now, he has more than 100 contacts in his phone book. The games are mostly strategic games. Other than gaming, he indulges in purchasing car and gadget magazines. He reads XXXXXXX Brown and other fantasy writters. One year back when he came back home, he became very nasty for purchasing new highest end laptop and smart TV, which I had to give. His mother was very sick during that time, but he was no way concerned.
He was first taken to psychiatrist, when he failed in 1st year. MMPI was conducted and 'Axpeta-10mg' twice a day was prescribed. He refused follow up indicating lack of ambience of the place. He wants every thing high-end. The second psychiatrist also pescribed the same medicine and later on 'Inspiral'. After a few follow up, he refused taking medicine indicating 'loss of interest'. In next follow up, he showed anger to the doctor. He was prescribed 'Risnia'-1mg/ml 10 drops twice a day, which was given without his knowledge. While on this medicine for 10 days, he complained loss of control in limbs and tongue. He was addmitted in a hospital and they advised to stop 'Risnia'. A few months later third psychiatrist was consulted. 'Szetalo'-twice a day was given and aftewards, 'Olimelt' 2.5mg - once a day was given. While on this second medicine for few days, his stool became jet black. Doctor stopped the medicine, indicating it is improbale. Again treatment got discontinued. After few weeks, when he was only sleeping and gaming, his mother told him "why are you behaving like a mad fellow?" He bacame furious and forced me to take him to first phychiatrist. They told me that he came there to prove that he is not mad. They further told, there is no medicine, he is having ASPD coupled with NPD. Again after waiting for few months, I found out an homeopath, expecting homeopathic madicines would have less side effects. While on this treatment for few months, he became more violent. Doctor stopped the medicine. The last medicine given was 'Hyoscyamus Niger'. All the medicines, except a first few were given without my son's knowledge and all these times something worse happened.
Please advise me on:
1) What is he suffering from?
2) What behavioural approach I can take to correct?
3) What sort of treatments he requires?
4) A good psychiatrist in Bombay.

Thank you very much for the guidance.

May I now request you to kindly delete the reports I attached. They are still available on the net and may be viewed by others.

Regards.

If he has got PD alone, whether any medicine would work?

For the past few months, he is seldom taking to us and when talking he is very harsh. But with outsiders he is ok. How to make him to talk to us?

If you are practicing, may I have your address so that I can visit you?

Regards.
