A dual diagnosis assessment should consider physical health alongside mental health and substance use. Physical illness can affect mood, sleep, concentration, treatment choices, and the level of care a person needs. Substance use and medicines can also create medical concerns that are not apparent from a psychiatric interview alone. The aim is a coordinated assessment that takes bodily symptoms seriously and identifies who will investigate and manage them.

This does not mean everyone needs an extensive set of scans or laboratory tests. A useful medical review starts with the person’s history, symptoms, existing conditions, medicines, examination, and relevant risks. Tests should answer clinical questions. The practical task for a patient is to provide a clear account and make sure important findings do not fall between the psychiatric, addiction, and primary care teams.

Physical symptoms deserve their own hearing

Fatigue, disturbed sleep, appetite change, palpitations, and difficulty concentrating may occur during mental illness, substance use, withdrawal, physical illness, or medication treatment. More than one explanation can be present. The National Institute of Mental Health notes, for example, that some medical conditions and medicines can produce symptoms resembling depression. That is a reason for appropriate medical assessment, not a reason to assume that every depressive symptom has an undiscovered physical cause.

Describe the symptom before offering an explanation: when it began, whether it is changing, what makes it worse, and how it affects daily activities. “I become breathless climbing the stairs” is information that deserves assessment even if anxiety is also present. Ask the clinician to explain which possibilities need to be considered and which changes would require a more urgent response.

Start with current safety and stability

Some concerns cannot wait for a routine outpatient assessment. Severe chest pain, a seizure, markedly impaired consciousness, serious breathing difficulty, or rapidly worsening confusion warrant emergency medical help. Someone who may be experiencing dangerous withdrawal also needs a timely medical assessment rather than a plan based only on willpower, privacy, or a preferred treatment destination.

Once immediate risks are addressed, the team can decide whether outpatient appointments, residential treatment, or hospital care fit the current situation. A comfortable residence and frequent therapy do not automatically provide medical monitoring. If a program uses external medical services, ask how those services are accessed and who decides when transfer is necessary. The care setting should be able to meet the person’s actual needs.

Bring a short medical history, including unfinished problems

List known illnesses, operations, significant injuries, allergies, previous severe withdrawal, and recent hospital visits. Include ongoing symptoms that have not yet received a diagnosis. An unfinished investigation, an abnormal result awaiting follow-up, or a referral that was never completed may be more important than an old condition that is now stable. Say what follow-up was recommended and why it did not happen.

It can help to divide the history into three headings: conditions currently treated, problems under investigation, and past events relevant to safety. Add the name of the clinician responsible for each active condition if known. This gives the assessing team a starting point for obtaining records and avoids treating every diagnosis in the file as equally current.

Explain the actual substance-use pattern

A medical review needs more than the name of a substance. Timing, approximate amount, route of use, combinations, changes in supply, and the last use may matter. Prescribed sedatives or pain medicines also belong in the discussion, including whether they have been taken differently from the prescription. Uncertainty is useful information: an unknown product should be described as unknown rather than assigned an assumed ingredient.

Previous experiences of stopping or reducing use can guide questions about risk. Tell the clinician about seizures, severe confusion, hospital treatment, or other serious events during an earlier attempt. Do not use this article to plan a withdrawal schedule. Our guide to a symptom and substance-use timeline can help you organize these events for an individual assessment.

Medication review connects the medical and psychiatric picture

Bring the medicines you actually take as a written list, including dose, schedule, prescriber, and recent changes when known. Add over-the-counter products and supplements. If a list in the medical record differs from current use, say so. A medicine may have been stopped, taken intermittently, or replaced by another product without every clinician knowing.

NIAAA describes potentially harmful interactions between alcohol and a range of medicines. The relevant issue is the specific combination, not whether the medicine came from a legitimate prescription. Ask the prescriber or pharmacist to review the full list and explain what to do if side effects or missed doses occur. Avoid independently stopping prescribed treatment to simplify the assessment.

Sleep, nutrition, pain, and everyday functioning are clinical information

A person may arrive focused on anxiety while also sleeping irregularly, eating very little, living with untreated pain, and missing treatment for an existing condition. These issues can affect the ability to participate in psychotherapy or manage medicines. They deserve practical attention, not a brief instruction to “live more healthily” after the main assessment has finished.

Give concrete examples. How many nights have been disrupted? Is eating difficult because of nausea, lack of appetite, money, dental pain, or fear? Does pain lead to extra medication use? Are there falls or difficulties managing stairs? The purpose is to identify what needs evaluation and support. A clinician can then decide whether a specialist opinion, nutritional assessment, or another service is indicated.

Discuss infection prevention and testing without stigma

Injection practices and other exposures can be relevant to HIV and viral hepatitis assessment. CDC guidance identifies people who use or inject drugs as a group for whom appropriate hepatitis prevention, testing, and care are important. Testing decisions should be discussed respectfully and connected to an explanation of what the result would mean and how follow-up would work.

You can ask to discuss sensitive details privately. If a test is offered, ask which infection it addresses, whether timing affects interpretation, how you will receive results, and what happens if further assessment is needed. A test without a plan for communicating and acting on its result leaves an avoidable gap. Preventive care should remain part of the plan after the initial crisis settles.

Ask what each proposed investigation will change

Testing is most useful when connected to a question. A clinician might be investigating a new symptom, checking the safety of a medicine, reviewing a known disease, or assessing a specific exposure. Ask for that purpose in ordinary language. You can also ask whether an existing result is recent enough and whether repeating it will add useful information.

More testing is not automatically more thorough care. A large package of tests may create findings that are difficult to interpret without improving the treatment decision. Equally, a blanket statement that every symptom is psychological is not a medical review. The appropriate balance is an explanation of what is being checked, why, and what will happen next.

Part of the review Useful question
New bodily symptom What needs medical assessment, and how soon?
Existing condition Who remains responsible while mental health treatment starts?
Medicine or supplement Does the full combination need a safety review?
Investigation What decision will this result help us make?
Abnormal finding Who will contact me and arrange the next step?

Make responsibility for follow-up explicit

Integrated care does not require every professional to work in the same building. It does require an agreed way to share relevant information and act on it. A psychiatrist may identify a physical concern that needs primary care follow-up; an addiction clinician may need information about a prescribed medicine; a hospital may send results after discharge. Ask who is coordinating these connections.

For each unresolved issue, record the next action, responsible person, and expected timing. If you are moving into residential treatment or traveling abroad, identify which clinician will receive incoming results while you are away. A referral being written is not the same as an appointment taking place. The plan should make that handoff visible.

Accommodations can make treatment possible

Physical health needs may affect transport, mobility, food, sleep arrangements, communication, and the pace of appointments. Mention these early rather than waiting until arrival. A program should be able to say which accommodations are available and where it needs external help. If an essential service cannot be provided reliably, the setting may need to change.

The same principle applies to routine treatment already working well. Starting mental health or addiction care should not accidentally interrupt an established medical appointment, monitoring plan, or supply of prescribed medicine. Discuss continuity before the move. The comprehensive assessment guide explains how these practical requirements fit into the overall care recommendation.

Leave with a joined-up plan

At the end of the review, ask for a concise explanation of current medical concerns, what has been ruled out or remains uncertain, planned investigations, and any implications for mental health or addiction treatment. You should know which symptoms to report promptly and which clinician to contact. A medical review is useful when it changes the next steps in a clear way.

The goal is to treat the whole situation with proportionate attention. Mental illness and substance use should not cause bodily symptoms to be dismissed, and physical investigations should not indefinitely postpone needed psychological or addiction care. A coordinated plan allows both to proceed with their responsibilities and priorities understood.
