Whether Neurocognitive Disorder Qualified as a Mental Disorder for Civil Commitment Purposes
In In the Matter of J.B., 339 Or.App. 354 (Or. Ct. App. 2025), the Oregon Court of Appeals examined a case involving an elderly woman, J.B., who was unable to meet her basic needs because of neurocognitive disorder with behavioral disturbances. She was civilly committed by the Circuit Court of Clackamas County. The appellant appealed on the basis that neurocognitive disorder with behavioral disturbances did not qualify as a mental disorder under Or. Rev. Stat. § 426.005(1)(f) (2017). The Court of Appeals of Oregon held that J.B.’s condition did qualify because of the associated functional impairments that significantly interfered with her executive functioning, judgment, and capacity to live independently.
Facts of the Case
On January 20, 2024, an 81-year-old woman, J.B., called 9-1-1 because of difficulty breathing. At the hospital, she was given oxygen and treated for leg blisters caused by warming her legs in the oven because of a lack of heat in her home, raising concerns about her mental health. She scored 8 of 30 on the Saint Louis University Mental Status (SLUMS) examination and was diagnosed with a neurocognitive disorder with behavioral disturbances, at least mild in severity and potentially related to Alzheimer’s disease.
J.B. demonstrated difficulty with complex attention, executive functioning, learning and memory, and speech, and exhibited judgment deficits in social cognition, and perceptual motor problems. Her neurocognitive disorder included behavioral disturbances, specifically paranoia manifesting as “a general distrust and suspicion about various people” (In re J.B., p 357). A psychiatrist who treated J.B. in the hospital for three days provided examples of her making paranoid statements about a neighbor and her daughter’s partner.
Don Glenn, an adult protective services specialist with the Department of Human Services, spoke with J.B. in the hospital and visited her home. J.B. confirmed to him the presence of rats and rodent droppings in her house, holes in the floors and ceilings, a very strong odor of urine, and a lack of working furnace or other major appliances. She had no fresh food and had been eating spoiled food. Mr. Glenn testified that, although J.B. was able to “identify the neglect in the home” (In re J.B., p 357), it was unclear if she understood the related risk. Mr. Glenn opined it was not advisable for her to return home.
The trial court found J.B. unable to meet her basic needs because of a mental disorder, and she was civilly committed. She appealed.
Ruling and Reasoning
The Oregon Court of Appeals affirmed the trial court’s decision to civilly commit J.B., finding that she met the statutory criteria under Or. Rev. Stat. § 426.130 for a person with a mental illness who is unable to provide for her basic needs.
J.B. argued that a neurocognitive disorder, including Alzheimer’s disease, did not qualify as a “mental disorder” under Or. Rev. Stat. § 426.005(1)(f) and therefore could not support civil commitment. The court rejected this argument, reasoning that the statutory definition of a mental disorder includes any medically recognized condition that impairs a person’s cognitive, emotional, or behavioral functioning to the extent that it significantly interferes with the person’s ability to meet basic needs.
The court looked to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) (American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Washington, DC: American Psychiatric Association, 2013) for guidance. The DSM-5 defines a mental disorder as a syndrome characterized by clinically significant disturbances in cognition, emotion regulation, or behavior, reflecting dysfunction in underlying psychological or biological processes. Under this framework, the court concluded that neurocognitive disorders, which involve progressive cognitive decline and functional impairment, meet this definition and are properly subject to civil commitment when the statutory criteria are otherwise satisfied.
This reasoning was distinguished from the court’s earlier decision in State v. A.B.K., 522 P.3d 894 (Or. Ct. App. 2022), which held that, although autism spectrum disorder fits within the DSM-5’s broad definition of mental disorder, Oregon’s statutory scheme treats developmental disabilities separately from mental illnesses for civil commitment purposes. In contrast, neurocognitive disorders, usually acquired later in life and involving functional decline, are excluded from developmental disability statutes and fall under civil commitment law.
The court emphasized that the key legal question was not whether Alzheimer’s qualifies as a mental disorder but whether the associated cognitive and behavioral impairments render the individual unable to care for herself. J.B. did not contest that she was unable to meet her basic needs as a result of her neurocognitive disorder. The court concluded that her disorder met the legal threshold for a mental illness under Oregon law and that her civil commitment was warranted to ensure her safety and well being.
Discussion
This ruling highlights the complex intersection of geriatric neurocognitive disorders, behavioral disturbances, and the legal standards for civil commitment under Oregon law. One important clarification presented by the case was whether or not a neurocognitive disorder with behavioral disturbances meets the statutory definition of a “mental disorder” under Or. Rev. Stat. § 426.005(1)(f). The Oregon Court of Appeals held that it does, relying on the DSM-5 definition of mental disorder as a clinically significant disturbance in cognition, emotion regulation, or behavior that is caused by dysfunction in psychological, biological, or developmental processes.
Critically, the ruling underscores the importance of functional impairment rather than the diagnosis alone. J.B.’s diagnosis of neurocognitive disorder with behavioral disturbances, although potentially rooted in Alzheimer’s disease, was not the ultimate basis for civil commitment. The diagnosis was considered clinically and legally significant because of its impact on her executive functioning, judgment, and capacity to live independently. The disconnect between limited insight and impaired functional capacity became central in evaluating her eligibility for involuntary civil commitment.
This case raises critical ethics questions about autonomy, dignity, and protection of vulnerable adults. Civil commitment involves a significant deprivation of liberty. When an individual’s cognitive impairment reaches a level where the individual is unable to assess danger, make reasoned decisions, or maintain self-care in even the most basic ways, the state’s ethical duty shifts toward intervention. This case illustrates the tension between respecting self-determination and society’s responsibility to ensure minimal standards of health and safety.
Clinically, the case illustrates the necessity of comprehensive, functionally oriented assessments. The court’s decision was supported by both standardized cognitive screening tools, such as the SLUMS examination, and qualitative evidence from clinicians and protective services professionals. Observations regarding J.B.’s paranoid ideation, poor judgment, and unsafe living conditions reinforced the real-world consequences of her impairments. The ruling affirms the value of interdisciplinary collaboration in civil commitment evaluations, where integrating medical, psychological, and social perspectives is essential to accurately assess risk and capacity.
