NEW DELHI: Mental health disorders are on the rise with 80% of people with any form of mental or substance use disorder in India and China not seeking treatment, a new report on mental health released by Lancet Commission says.Underlining the treatment gap and the heavy economic toll exacted by mental illness, the report says the disorder will cost the global economy $16 trillion by 2030. According to an earlier report published in Lancet, the burden of the disease in India increased from 3% in 1990 to 6% in 2013, whereas in China mental, neurological and substance-use disorders, accounted for 7% of disability-adjusted life years in 1990 and the percentage increased to 11% by 2013.Present estimates show people with mental illnesses account for nearly 6.5% of India's population and is projected to increase to 20% by2020. Without factoring in suicide, mental health issues are projected to reduce economic growth in both India and China by more than $9 trillion respectively between 2016 and 2030."Driven by violence, environmental changes and inequality, mental disorders are going unchecked in every country in the world. Governments are failing both to prevent mental disorders and provide treatment of acceptable quality," the report said.Though the report acknowledged India's efforts to get in place the landmark mental health care bill in 2017 entitling people with mental disorders to access comprehensive medical and social care services in community settings, it said the quality of care continues to be poor for mental health patients."Even when treatment is sought, its quality is poor - the World Mental Health Surveys reported that one in five people with depressive disorder received minimally adequate treatment in high-income countries, dropping to just one in 27 in LMICs (low and middle income countries)," the report said.It added, recovery-oriented community mental health services are inaccessible to the overwhelming majority of the global population, and inpatient care, including emergency care and long-term social care, is dominated by large institutions or prisons. The report, which brought together 28 global experts in psychiatry, public health, neuroscience , advocacy and people with first-hand experience of mental health conditions, also raised concerns about inadequate investments in mental healthcare across the globe.
