What the week is
A week set by Congress, run by NAMI, with a theme about science
Mental Illness Awareness Week has been observed during the first full week of October since 1990, when Congress established it after advocacy by the National Alliance on Mental Illness. In 2026 it runs from Sunday, October 4 to Saturday, October 10.
NAMI chose “Turning Science Into Hope” as the 2026 theme. The idea is simple: research into the brain becomes treatments, and people who live with mental illness shape what that research asks. The week shares the calendar with World Mental Health Day, which the World Health Organization marks on October 10 every year. The WHO theme for 2026 is about lived experiences being heard.
An awareness week does not diagnose or treat anyone. It gives families a reason to start a conversation they have been avoiding, and it gives people who have been putting off care a date to act on.
The numbers behind the week
What federal surveys say about mental illness in the United States
The figures below come from the National Institute of Mental Health, the Substance Abuse and Mental Health Services Administration, and CDC death records. Each row names its source; the links are in the sources list at the bottom of the page.
| Figure | What it means | Source |
|---|---|---|
| 59.3 million | U.S. adults who lived with a mental illness in 2022. That is 23.1 percent, more than one in five. | NIMH, 2022 survey |
| 50.6 percent | The share of those adults who received any mental health treatment that year. Almost half received none. | NIMH, 2022 survey |
| 21.0 million | U.S. adults who had at least one major depressive episode in 2021, 8.3 percent of adults. About 61 percent of them received treatment. | NIMH, 2021 survey |
| Before age 18 | When about half of all mental health conditions have shown their first signs. About one third begin before age 14, and nearly two thirds before age 25. | Solmi et al., 2022 meta-analysis |
| 49,316 | Suicide deaths in the United States in 2023. Suicide was the second leading cause of death for ages 10 to 34. | NIMH, from CDC data |
NIMH figures come from the National Survey on Drug Use and Health, which counts adults aged 18 and older. “Mental illness” there means any mental, behavioral, or emotional disorder in the past year, from mild to severe. The suicide figures are CDC WISQARS counts for 2023, as reported by NIMH.
Why stigma matters
The gap between living with a condition and being treated for it
The most useful number in the table is the treatment rate. In 2022, among 59.3 million adults with a mental illness, 30.0 million received treatment and 29.3 million did not. For major depression in 2021, about four in ten adults who had an episode got no treatment that year.
Surveys do not record every reason a person goes untreated, and cost, access, and wait times are part of it. NAMI built this week around one reason it can change: silence. Its own framing is that breaking the silence around mental health is how stories become science, and science becomes hope. The practical version for a family is shorter. A condition that is named can be treated; one that is hidden cannot.
- About one third of mental health conditions show their first signs before age 14, about half before age 18, and nearly two thirds before age 25, according to a 2022 analysis of 192 studies. Early conversations are not early.
- Depression is a medical condition with treatments that work for most people. When the first ones do not, there are further options, and they are covered on this site.
- Saying the words “I think I need help” to one person is a treatment step. The next one is a clinician.
How to help someone
Five steps NIMH recommends when someone is in emotional pain
The National Institute of Mental Health publishes five action steps for helping a person who may be thinking about suicide. They are written for family and friends, not clinicians, and they fit any week of the year.
- 1Ask
Ask the direct question: “Are you thinking about suicide?” Research summarized by NIMH finds that asking does not increase suicidal thoughts. Then listen to the answer without arguing with it.
- 2Be there
Stay with the person, in the room or on the phone. Being present and taking the conversation seriously lowers the sense of being alone with it.
- 3Help keep them safe
Ask whether they have a plan and whether they have access to the means. Putting time and distance between a person and lethal means saves lives.
- 4Help them connect
Save 988 in their phone and yours. Help them reach a clinician they already know, or help them find one. Offer to make the first call together.
- 5Follow up
Check in after the hard day passes. A text, a call, or a visit in the days that follow is part of the support, not an extra.
For questions that are not a crisis, the NAMI HelpLine answers Monday to Friday, 10 a.m. to 10 p.m. Eastern: call 800-950-6264 or text NAMI to 62640. For a crisis at any hour, call or text 988, or chat at 988lifeline.org. Spanish and videophone options are available.
When treatment has not been enough
What this site adds: the next conversation after antidepressants fall short
Most depression education stops at “get help.” Advanced Depression Care starts where help has been tried. If two or more adequate antidepressant trials have not brought enough relief, clinicians call that treatment-resistant depression, and the next conversation is different.
Use the week to ask one specific question of the clinician who manages the treatment: what is the next step if this plan does not work? The guides below explain what a specialist review covers, which treatments exist beyond medication, and what to ask a treatment center before scheduling.
- What treatment-resistant depression means, and what a reassessment checks before anything new is added.
- When antidepressants fail: the patient guide to optimizing, switching, combining, and augmenting.
- TMS, SPRAVATO / esketamine, and ECT: what each treatment is, who it is discussed for, and what a course involves.
- Questions to ask a treatment center before the first appointment.
Common questions
Questions people ask about the week
When is Mental Illness Awareness Week in 2026?
October 4 to 10, 2026. NAMI runs it during the first full week of October every year. Congress established the week in 1990 after NAMI's advocacy. World Mental Health Day, set by the World Health Organization for October 10, falls inside the same week.
What is the 2026 theme?
NAMI's theme for 2026 is “Turning Science Into Hope.” It centers on how research, shaped by the lived experience of people with mental illness, turns into treatments and recovery. The WHO theme for World Mental Health Day on October 10, 2026 is about lived experiences being heard.
How common is mental illness in the United States?
More than one in five adults. The National Institute of Mental Health reports that 59.3 million U.S. adults, 23.1 percent, had a mental illness in 2022. Just over half of them, 50.6 percent, received treatment that year.
What should I do if someone tells me they are thinking about suicide?
Stay with them, ask directly about a plan and access to means, and connect them to help. Call or text 988 together, or chat at 988lifeline.org. If they are in immediate danger, call 911. Then follow up in the days after. These are the five steps NIMH recommends: ask, be there, help keep them safe, help them connect, and follow up.
Is a week of awareness the same as getting care?
No. The week is a reason to start. Care is an evaluation with a licensed clinician who can diagnose and treat. If depression has already been treated and has not improved enough, this site's guides explain what a specialist conversation about treatment-resistant depression covers, including TMS, SPRAVATO, and ECT.
