A common diagnosis in psychiatry is bipolar disorder. Though
Dr. Hagop S. Akiskal may have propounded a 7 type classification of bipolar
disorder which is very famous but it is an equally well-known fact that the most
common classification practiced is of Bipolar 1 and Bipolar 2.
Now what it is being Bipolar?
Bipolarity in its common meaning means exhibiting 2
different poles in same person and that is exactly what happens. A person diagnosed as bipolar disorder certainly falls into depression for months and
then lifts into mania or hypomania. Many people exhibit swings of mood from
being into sad state to joyous. Are they always bipolar?
A simple answer is no. There is a specific set of symptoms which
should be exhibited for certain duration of time to be called bipolar.
Now let us discuss both commonly used of bipolar disorder types.

bipolar 2 with depressive.
