Prognosis of schizophrenia

John Nash, a US mathematician, began showing signs of paranoid schizophrenia during his college years. Despite having stopped taking his prescribed medication, Nash continued his studies and was awarded the Nobel Prize in 1994. His life was depicted in the 2001 film A Beautiful Mind.

The prognosis of schizophrenia is varied at the individual level. In general it has great human and economics costs.[1] It results in a decreased life expectancy of 12–15 years primarily due to its association with obesity, little exercise, and smoking, while an increased rate of suicide plays a lesser role.[1] These differences in life expectancy increased between the 1970s and 1990s,[2] and between the 1990s and 2000s. This difference has not substantially changed in Finland for example – where there is a health system with open access to care.[3]

Schizophrenia is a major cause of disability. Approximately three quarters of people with schizophrenia have ongoing disability with relapses.[4] Still some people do recover completely and additional numbers function well in society.[5][6]

Most people with schizophrenia live independently with community support.[1] In people with a first episode of psychosis a good long-term outcome occurs in 42% of cases, an intermediate outcome in 35% of cases, and a poor outcome in 27% of cases.[7] Outcome for schizophrenia appear better in the developing than the developed world.[8] These conclusions however have been questioned.[9][10]

There is a higher than average suicide rate associated with schizophrenia. This has been cited at 10%, but a more recent analysis of studies and statistics places the estimate at 4.9%, most often occurring in the period following onset or first hospital admission.[11] Several times more attempt suicide.[12] There are a variety of reasons and risk factors.[13][14]
