![]() Comorbidity is probably due to the effect of the same causal factors in different disorders (Krueger, 2006). There is also high comorbidity between mental disorders and substance use disorders (Hasin, 2015). Over a 12 -month period, almost half of those who have a mental disorder will also experience one or more other mental disorders, according to a German study (Jacobi, 2015).Ĭomorbidity between anxiety and depression is particularly strong (Kessler, 2005 Jacobi, 2015).In the Oslo survey conducted from 1994 to 1997, it was estimated that 11.9 per cent of the population would experience two mental disorders during their lifetime, while 14.9 per cent would have three or more (Kringlen, 2001 ). Half of those with mental disorders have at least two mental disorders Indicators of lifetime prevalence are un reliable because people have limited recall of psychiatric symptoms, resulting in under - reporting of earlier disorders. Approximately 1 - 3.5 per cent of people will have a psychotic disorder during their lifetime (Perala, 2007 Kringlen, 2001).About one in ten people will have a depressive disorder over the course of a year.Around 15 per cent of people will have an anxiety disorder over the course of a year.Tables 3 and 4 show the 12-month and lifetime prevalence of the various disorders, respectively. These concern specific situations such as fear of dentists, heights, the dark, enclosed spaces, animals or blood. Phobias are the most common type of disorder. The most common mental disorders among adults are anxiety disorders, depression, and substance use disorders see the chapter on Substance use disorders. Over the course of 12 months, around 16 - 22 per cent of the adult population will experience a mental disorder (Table 3). Prevalence of mental disorders among adults This survey, a collaboration between the Norwegian Institute of Public Health and the Health Survey in Nord-Trøndelag (HUNT), is a pilot for a national survey. In 2019, a diagnosis-based survey will be conducted among adults aged 20-65 in the county of Nord-Trøndelag. However, two older regional surveys and a survey of a sample of twins have been published (see Table 1). There have been no national diagnosis-based population surveys in Norway. The registry data w ere obtained from the Norwegian Patient Registry (NPR), the Norway Control and Payment of Health Reimbursement (KUHR) Database and the Norwegian Prescription Database (NorPD). In this chapter, we have used systematic literature searches and registry data analysis. Mental disorders are diagnosed by doctors and psychologists using structured clinical interviews. I nternational diagnostic criteria are regularly revised as scientific evidence is updated (First, 2017). The term ‘mental disorder’ refer s to a wide variety of conditions and diagnoses. We know little about the individual causes, but both genetic and environmental factors increase risk of developing a mental illness.Mental disorders and substance use disorders often occur at the same time.Between one in six and one in four people will suffer from a mental disorder over the course o f a year. ![]()
