The World Health Organization does not define mental health as the absence of illness. Its fact sheet, updated in September 2026, describes a positive state that everyone has to some degree, including people who live with a diagnosed condition. The definition matters for programmes because it widens the target: a livelihood or education project can protect mental health even if it never treats anyone.

Practitioners meet three overlapping terms, and the difference decides who a programme is designed for. WHO's mental disorders fact sheet (September 2026) sets them out. The narrowest is a disorder that meets diagnostic criteria. The broadest is a mental health condition, which includes distress and disability that may never reach a diagnosis.

The International Classification of Diseases is WHO's system for coding illness and death. Its eleventh revision was approved by the World Health Assembly in 2019 and became effective for health reporting in January 2022. WHO's 2022 release note says it holds around 17,000 unique codes and is fully digital. Mental conditions sit in the grouping for mental, behavioural and neurodevelopmental disorders.

The Mental Healthcare Act, 2017 (Act 10 of 2017) received assent on 7 April 2017 and came into force on 29 May 2018. Its definition in section 2(1)(s) sets the threshold for every right and duty that follows, so it is worth reading in full.

The Mental Healthcare Act opens by citing the UN Convention on the Rights of Persons with Disabilities, which India signed on 30 March 2007 and ratified on 1 October 2007, and says the Act aligns Indian law with it. The older Mental Health Act, 1987 was mainly about admitting and detaining people. The 2017 Act begins with capacity and choice.

WHO's World mental health report, published in June 2022, was the largest review of the subject since 2001. It found that mental disorders are the leading cause of disability and that people with severe conditions die 10 to 20 years earlier than the general population, mostly from preventable physical disease. It also found the money going to the wrong place: 2 out of every 3 dollars of government spending on mental health went to stand-alone psychiatric hospitals rather than community services.

The care gap is the share of people with a condition who receive no care, or care too poor to help. WHO's 2022 report put numbers on it for two conditions, and the gap is widest where incomes are lowest. Coverage figures alone hide quality: a person may see a doctor once, receive a prescription and never return.

The India State-Level Disease Burden Initiative applied the Global Burden of Disease method to every state. Almost all of this burden is years lived with disability rather than early death, because GBD counts suicide deaths under injuries. The study also found that disorders that begin mainly in childhood were more common in the less developed northern states, and those that begin mainly in adulthood in the more developed southern states. It reported a modest state-level correlation between depression prevalence and the suicide death rate, for women and for men.

Public reporting from 2025 and 2026 describes a second National Mental Health Survey run by NIMHANS for the Ministry of Health, designed to cover all states and union territories and both adolescents and adults. As of October 2026 we could not find a published report or an official prevalence figure from it, so this deck uses the 2015-16 survey for India's national numbers.

This section discusses suicide as a public health problem. It follows WHO's media guidance: no methods, no locations, and information on where to get help. If this material raises anything difficult for you, Tele-MANAS (14416 or 1-800-891-4416) is free and runs round the clock in India.

WHO's LIVE LIFE initiative (2021) names four interventions with the best evidence: limit access to the means of suicide, work with the media on responsible reporting, build socio-emotional life skills in adolescents, and identify, assess, manage and follow up anyone affected by suicidal behaviour. WHO calls banning highly hazardous pesticides a particularly inexpensive and cost-effective intervention.

Vikram Patel and Arthur Kleinman reviewed community studies from six low- and middle-income countries in the Bulletin of the World Health Organization (2003). Most found that indicators of poverty were associated with common mental disorders, and the most consistent link was with low education. The evidence for a link with income alone was weaker.

Aashish Gupta and Diane Coffey analysed 10,125 adults in WHO's Study on Global Ageing and Adult Health in India (Population Research and Policy Review, 2020). They found large gaps in self-reported mental health between higher caste Hindus and two marginalised groups, Scheduled Castes and Muslims. Differences in socio-economic status could not fully explain the gaps, especially for Muslims.

WHO's depression fact sheet (updated 11 September 2026) reports that depression is about 1.5 times more common among women than men, and that more than 10% of pregnant women and women who have just given birth experience depression worldwide. NMHS 2015-16 found current depression in 3.0% of women and 2.4% of men. The WHO 2022 report names childhood sexual abuse and bullying as major causes of depression.

Section 18(2) says what the right means: services of affordable cost and good quality, in sufficient quantity, geographically accessible, without discrimination on grounds including gender, sexual orientation, religion, caste, class or disability, and acceptable to persons with mental illness and their families.

Section 115(2) then places a duty on government to provide care, treatment and rehabilitation to a person who has attempted suicide, to reduce the risk of a further attempt. The law therefore moved the response from the police station to the health system.

These two provisions matter to development practitioners in different ways. Outreach workers who find a homeless person in crisis can involve police under a statutory duty of care. Evaluators planning a trial or survey that includes people with mental illness must build section 99 into their protocol, alongside the ICMR guidelines covered in Section 10.

India launched the National Mental Health Programme (NMHP) in 1982, with the aim of making mental healthcare part of general healthcare instead of confining it to specialised hospitals. The District Mental Health Programme (DMHP) brought community services to the district level. The PIB backgrounder of 7 February 2025 reports that the DMHP covers 767 districts.

The Ministry of Education's Manodarpan initiative was inaugurated on 21 July 2020 to provide psychosocial support to students, teachers and parents during the COVID-19 pandemic and after it, including a toll-free tele-counselling line. In 2023 the Ministry circulated draft guidelines called UMMEED for schools on preventing suicide, built around a school wellness team that identifies students at risk and responds first.

Bangladesh's Mental Health Act, 2018 (Act 60 of 2018), dated 14 November 2018, repealed the Lunacy Act, 1912. Its preamble says the old law had lost relevance and that a new law was needed to secure care, dignity, property rights, rehabilitation and overall welfare for people with mental health problems.

Pakistan's Mental Health Ordinance, 2001 replaced the Lunacy Act, 1912. After the 18th constitutional amendment in 2010, health became a provincial subject, and provinces passed their own laws: Sindh in 2013 and Punjab in 2014 (Tareen and Tareen, BJPsych International, 2016).

Sri Lanka still runs on the Mental Diseases Ordinance, whose origins lie in 1873. The Morning (29 March 2026) reported that a concept paper for a new Mental Health Bill had been presented to Cabinet and that public consultations had begun, including sessions at the Human Rights Commission of Sri Lanka. The draft would shift the law from custody toward rights and community care.

With few psychiatrists and psychologists, waiting for specialists means most people are never treated. Task sharing trains people without professional mental health qualifications, such as community health workers, lay counsellors and volunteers, to deliver structured psychological help, with supervision from specialists. WHO's 2026 mental health fact sheet names task sharing with non-specialist providers in primary care as part of community-based care.

Field staff hear disclosures of violence, debt and grief, and counsellors carry suicide risk. WHO's 2023 media guidance recognises that professionals covering suicide may themselves be affected, and the same holds for programme staff. Organisations owe staff the protections they promote for others.

WHO's fact sheet on mental health in emergencies says almost everyone affected by an emergency experiences psychological distress, which usually improves over time. One in five people (22%) who experienced war or conflict in the previous ten years has depression, anxiety, post-traumatic stress disorder, bipolar disorder or schizophrenia. People with severe conditions are especially vulnerable when services break down.

The ICMR National Ethical Guidelines for Biomedical and Health Research Involving Human Participants (October 2017) list people with mental illness among vulnerable groups needing additional safeguards set by the ethics committee. They are equally clear that vulnerable groups have a right to be included, so that research benefits reach them.

The common thread across the deck is the gap between effective care and the people who need it. Most of that gap sits outside hospitals, in villages, schools, workplaces and camps where development programmes already work.
