Bipolar disorder or sometimes called as manic depressive disorder, is a mental health condition that affects individuals across gender, race, ethnicity, economic background, educational attainment and age. It is a disorder of chemicals in the brain that control and stabilize an individual’s mood causing extreme shifts in behavior. Such shifts are referred to as “mood episodes” categorized in two. One is the manic phase wherein the individual experiences an unusual boost of energy, some feel unwarranted happiness and some often experience rushing of thoughts, inspirations and inability to focus. The other phase is a depressive state wherein the individual experiences loss of interest in previously enjoyable activities or even regular activities of daily living. This phase may be manifested by either excessive need for sleep or inability to fall asleep; some may feel demotivated coupled by feelings of shame, guilt and worthlessness.
According to the National Institute of Mental Health (NIMH), the incidence of Bipolar disorder worldwide is around 1.1% for the population of individuals over the age of 18. Roughly around 51 million people globally have bipolar disorder:
• Around 12 million in China
• Around 8.7 million in India
• Around 2.2 million in the USA
• Around 285,000 in Australia
• Around 280,000 in Canada
• Around 250,000 in Britain
Statistics by gender
The National Comorbidity Study revealed that the condition has a higher prevalence in men as compared to women and also that it develops in an earlier age in men.
Bipolar disorder occurs in both men and women and usually starts in adolescence but can develop as late as 40 to 50 years of age.
The onset of the common symptoms of Bipolar disorder which are manic episodes and depressive episodes vary in men and women. Women are more likely to develop the disorder with a depressive episode manifesting first as compared to men who develop the illness with a manic episode occurring first.(Journal of Clinical Psychiatry, 58, 1995 [Suppl.15])
With the discrepancy in gender, this could lead to difficulty in diagnosing the illness; men are more likely to be misdiagnosed to be suffering from schizophrenia while women are more likely to be misdiagnosed with depression.
Treatment and outcome
Statistics shows that those get treatment and medications early have a better medical outcome than those who delay the medications and therapy.
Teenagers with bipolar disorder have a 50% risk for attempting suicide, but those who enter a medical program early in the diagnosis of the illness show marked improvement in behavior and stability of mood.
In a book written by Dr. E. Fuller “Surviving Manic Depression (Bipolar Disorder)” it is noted that
After 10 years, of the people diagnosed with bipolar disorder:
• 25% Completely Recover
• 25% Much Improved, relatively independent
• 25% Improved, but require extensive support network
• 15% Hospitalized, unimproved
• 10% Dead (Mostly Suicide)
After 30 years, of the people diagnosed with bipolar disorder:
• 25% Completely Recover
• 35% Much Improved, relatively independent
• 15% Improved, but require extensive support network
• 10% Hospitalized, unimproved
• 15% Dead (Mostly Suicide)

Statistics co-existing mental disorders co-existing with Bipolar disorder
A study partially funded by the NIMH regarding the “International impact of Bipolar Disorder” which was published in the March 2011 issue of the Archives if General Psychiatry revealed that:
From the countries that were part of the study, 75 percent of those diagnosed to have bipolar disorder also suffer from another disorder, namely anxiety disorders, with a special connection with panic disorders, these were followed by substance abuse disorders and behavior disorders noting that the pattern of prevalence in individuals is similar despite the data coming from different countries.
