This bill amends the definitions within the Mental Health Law as outlined in 43A O.S. 2021, Section 1-103. Key modifications include the clarification of terms such as "person requiring treatment," which now specifies that individuals posing a substantial risk of harm to themselves or others must meet certain criteria without the requirement of "immediate" harm. Additionally, the definition of "assisted outpatient" has been updated to reflect a broader timeframe for assessing a person's history of treatment noncompliance, extending it from twenty-four months to thirty-six months. The bill also introduces new language regarding the treatment of individuals with traumatic brain injuries and clarifies the role of mental health professionals in the treatment process.

The bill further emphasizes the importance of considering a person's mental health or substance abuse history in determining their need for treatment, while ensuring that such history cannot be the sole basis for this determination. It also outlines the responsibilities of facilities in providing individualized treatment plans and the conditions under which a person may be discharged or transported for further medical care. The act is set to take effect on November 1, 2026.
