           31 year old engineering male student

C/o :-

• Depression. says people call him insane!
• wearing bright clothes & lots of jewellery, seems very restless, pacing up and down the waiting room. he is mumbling to himself and intermittently starts singing rather loudly.
• when the assistant doctor approaches to calm him, he starts shouting and swearing loudly and becomes quite intimidating and threatening.
• for the past 15 days he has had broken sleep, but despite that he feels full of energy. on asking about reason for broken sleep he said he is working on a breakthrough invention that would revolutionize his field.
• there isn't any known adverse medical history.
• no psychiatric history apart from the depressive episodes.
• lives in PG. doesn't have any as such friends! likes to be left alone with his work. wants to be millionaire as soon as it is possible!
• smokes 15-20 cigarettes a day and engages in social drinking using no more than two units a week.

Does these details are enough to initiate treatment?

• If NO, what should be further questions / investigations? 
• If YES, what should be further management?
