Addiction rarely arrives on its own. Anxiety, depression, PTSD and old trauma travel with it — and treating one without the other is why so many people relapse. Ona treats both at the same time, on 270 private acres in Northern California.
Independently certified for the highest national standards of quality and safety in behavioral health care.
Ona Treatment Center›Dual Diagnosis Treatment
Dual diagnosis · co-occurring disorders
Dual diagnosis — also called co-occurring disorders — means living with a substance use disorder and a mental health condition at the same time. Anxiety, depression, PTSD, bipolar disorder and unprocessed trauma are the ones we see most often. Treating either one on its own tends not to hold.
The reason is not complicated. If someone has been drinking to quiet panic, taking the drink away leaves the panic exactly where it was. If someone's depression lifts in treatment but nothing has touched the using that deepens it, the depression returns with the next relapse. The two feed each other, so they have to be treated together.
Ona was built for that. Our dual diagnosis program treats the substance and what sits beneath it at the same time — gently, and at your pace — with a plan written for one person rather than for a diagnosis code, and a clinical team that holds both halves of the picture at once.
Who it helps. People who have been through treatment before and relapsed once life got loud again. People who were told to get sober first and come back about the trauma later. And people who have never been assessed for a mental health condition at all, because the drinking or the using was the only thing anyone ever looked at.
Dual diagnosis care runs through everything here: medical detox where it is needed, residential treatment on 270 private acres, and medication-assisted treatment where it helps. Confidential admissions, 24/7: (530) 869-6163.
A dual diagnosis plan is not two programs bolted together. It is one clinical team, one plan, and therapy chosen for the whole picture rather than for whichever problem got named first.
Our core curriculum — a nationally recognized, evidence-based program addressing physical, emotional and mental health, with life skills in stress management, communication and relapse prevention.
Medical and psychological, on arrival — so the plan is built on what is actually there rather than on a guess.
Substance use and mental health held by the same team, reviewed together, not handed between departments.
Rewire the thought patterns that keep both the using and the anxiety or depression in motion.
Gentle, creative pathways to process what words cannot yet reach — at your pace, never forced.
Because a co-occurring disorder is lived by a household, and recovery can help repair one.
A written plan for the situations that were hardest before, including the mental health side of them.
If you're reading this for yourself — or for someone you love — you already know how heavy this has become. What you may not know is how different life can feel just a few weeks from now.
Ona was built for the whole story: not only the substance, but the anxiety, depression and trauma beneath it. Our dual diagnosis program treats both together — gently, and at your pace — because lasting recovery demands it.
Every treatment plan at Ona is built around one person: you. Guided by ASAM clinical criteria and the evidence-based Living in Balance curriculum.
