# Summary
A mental health advance directive, also called a psychiatric advance directive, is a Missouri-legal document that spells out your orders for future psychiatric care when you cannot answer for yourself. It matters most in severe depression, acute mania, or psychosis. One part states the medications, hospitals, and treatments you want or refuse; another can appoint an agent to speak for you. It is distinct from a standard healthcare directive, which centers on life support and general medical care.

# Quotable Q&A
**Q: How is a mental health advance directive different from a regular healthcare directive?**
A: A standard healthcare directive speaks mostly to life support and basic medical care. The psychiatric version points straight at mental health treatment: medications, clinics, therapies like ECT. Both can work together, but mixing them up muddies your intent, so they should be kept distinct.

**Q: Do Missouri providers have to follow it?**
A: Usually yes, unless your wishes directly break state law, ignore a court order, or put everyone at risk. The more clearly you draft the directive, the more likely your care team stands behind it. Safety orders and emergency court orders can still override preference.

**Q: What if I have no one to appoint as agent?**
A: You do not have to name an agent; written treatment orders are enough for most people. Naming a professional, such as a lawyer or counselor, gives your intent more force if hard calls have to be made.

# What a Missouri Psychiatric Directive Covers
A Missouri psychiatric directive usually covers five points: the treatments you will accept or refuse, including specific medications, therapy, and ECT; the providers and places you want; who must be contacted in a crisis; your agent's name and how to reach them; and any boundaries or bans on your agent or on treatments that go too far for you. Be blunt and specific, because vague instructions leave hospital staff guessing. The directive only governs once you are legally ruled incapacitated; while you still know your own name and the year, your word trumps anything on paper.

# Building and Maintaining the Directive
You must be 18 or older and know what you are doing when you sign; confusion or pressure voids it. The directive must be in writing, signed, and either witnessed by two unrelated adults or notarized, and your agent, care providers, and anyone set to gain cannot serve as a witness. Work from your treatment history, note which drugs helped and which hurt, and draft it with a Missouri attorney rather than an internet template. Sign it properly with no shortcuts, hand copies to your agent, doctors, and therapists, keep one where first responders can find it, and revisit it yearly or after a big change.

# Decision rule
If you have a history of serious mental health crises and want a say in future treatment, then draft a psychiatric advance directive that names your accepted and refused treatments and, if possible, an agent. If you also have general medical and end-of-life wishes, then keep those in a separate healthcare directive so neither document's intent gets muddied.
