<s>[INST] Hi my son Bradley left home 8 weeks ago.  His doctor said he was having a manic episode.  Since leaving he has made no attempt at contacting me.  I am unsure at this stage where he is now living.  I sometimes wonder whether he is borderline personality as well as Bipolar.  I am unsure whether he is taking his medication.  Do I wait this out as the doctor suggested and will he crash eventually.  He went to live with mt son who drinks heavily and maybe drugs involved. [/INST] Hi dear, After going through your query I can suggest that persons with borderline personality will be having the behavior problem right from age of 18 years with some micopsychotic episodes.whereas patients with bipolar disorder will have two manic episodes or one episode of depression and one of mania with full inter episodic recovery.general bipolar patients in manic episode hardly take medicines of their own in initial period. So take care he should take medicines regularly. </s>
