Updated March 2011

 

SUMMARY: For the past 20 years, studies have consistently estimated that almost half of all individuals with schizophrenia or bipolar disorder are receiving no treatment for their mental illness at any given time. According to recent estimates of NIMH, this means that approximately such individuals are receiving no treatment.

45 percent untreated

In 2010, the National Institute of Mental Health (NIMH) estimated that 40 percent of adults with schizophrenia and 51 percent of individuals with severe bipolar disorder receive no treatment in a one-year period. NIMH also estimated that there are 2.6 million adults with schizophrenia (1.1% of the adult population) and 5.1 million adults with severe bipolar disorder (2.2% of adult population). That means that there are

41 percent untreated

Mark Olfson et al. at Columbia reanalyzed 2003 national Medicaid claims for 49,239 individuals with schizophrenia who were hospitalized. They found that 41 percent of the patients received no psychiatric follow-up treatment in the month following their discharge from the hospital. The strongest predictors of which patients would not get follow-up treatment were substance abuse and a history of not having received treatment prior to their hospitalization.

54 percent untreated

Using data for the National Comorbidity Survey (NCS) carried out in 1990–1992, the authors reported that 54 percent of individuals with serious mental illness (broadly defined) had received no treatment in the previous 12 months.

46 percent untreated

By examining prescription refill records on 25,000 patients, it was found that 46 percent of individuals who had been taking antipsychotic medications were no longer taking the medications 9 months later. This study focused only on patients who were in the treatment system and did not include those who were homeless, incarcerated, etc.

42 percent untreated

In another follow-up of the ECA study data, it was established that 42 percent of individuals with severe mental illnesses (as defined by the NIMH Advisory Mental Health Council) were not being treated.

35 percent untreated
