  • identified through the presence of emotions that are usually uncontrollable and irrational


  • as of now, there is no single cause
  • scientific studies indicate that it may be genetically inherited; however, this is not known for certain
  • linked to brain structure and functioning
  • can also be caused due to environmental factors and stress
  • through brain imaging, it is seen that individuals diagnosed with bipolar have a smaller, and lower functioning prefrontal cortex

There are currently four types of bipolar disorder:

  1. Bipolar I Disorder: manic or mixed episodes last longer than seven days, symptoms are severe enough to require hospitalization, depressive episodes last longer than two weeks
  2. Bipolar II Disorder: obvious pattern of depressive and manic episodes, symptoms are not as severe as bipolar I disorder
  3. Bipolar Disorder Not Otherwise Specified: symptoms do not match requirements of bipolar I or bipolar II disorder
  4. Cyclothymia: symptoms are not severe, usually diagnosed through the presence of depression that has lasted for longer than two years


  • is not curable, but can be managed over the long-term
  • is a lifelong illness that requires ongoing treatment in order to control the severity of the symptoms
  • medication treatment is available: mood stabilizers, antipsychotics, and the use of antidepressants
  • psychotherapy is used alongside medication (cognitive behavioural therapy, family-focused therapy, social rhythm therapy)
  • other treatments: sleep medication, herbal medication, etc.
