Changes in the HIV/AIDS Epidemic
In USA & Developed Nations• Dramatic & significant reduction in the mortality
rate by more than 50% since 1995• Now moved to 14th leading cause of death overall• Moved from 1st to 5th leading cause of death
amongst 25-44 year olds

• Medical Treatment Evolution
– Monotherapy in early 1990s
– Dual agent approach by mid 1990’s
– Combination antiretroviral therapy (ART), also called highly active antiretroviral therapy (HAART), since late 1990s: 3 or more agents

• Prevalence of bipolar disorder in HIV infection is 10 times higher than in general population
(Lyketsos 1993)
• Stress of HIV infection exacerbates pre-existing bipolar disorder – complicating adherence
• New-onset or secondary mania – result of HIV infection, opportunistic infections or due
to antiretroviral medications
