Getting a Mental Health Diagnosis

Mental illness is common. Each year, millions of people are diagnosed with mental, behavioral, or emotional disorders. Importantly, effective treatments are increasingly available. These treatments, such as psychotherapy, medication, or a combination of these approaches, can significantly improve symptoms and daily functioning. Because treatment is often tailored to specific mental health conditions, obtaining an accurate diagnosis can help ensure that you receive the most appropriate care.

A diagnosis can help explain distressing symptoms, guide treatment decisions, and give people a clearer understanding of what they are experiencing. For many, a diagnosis can also be validating, as it can provide the language for an experience that may have felt confusing or otherwise overwhelming. While a diagnosis is not required to begin therapy, it can be helpful or necessary in certain circumstances, such as in obtaining workplace accommodations or receiving insurance coverage for treatment.

How to get a mental health diagnosis

Diagnosis typically involves an assessment conducted by a trained clinician. It usually starts with a clinical interview in which the person provides a detailed symptom history in response to a series of questions. A person will be asked about their main concerns, when symptoms started, under what conditions symptoms are most intense, and how the symptoms affect their everyday functioning. Skilled diagnosticians not only consider the answers to such questions in establishing a diagnosis; they also take into account a person’s emotional tone, demeanor, attitude, appearance, and responsiveness. They also assess a person’s mental status, such as the ability to think clearly, remember facts, and sustain attention.

In addition to symptom history, clinicians consider personal, family, and lifestyle factors when making a diagnosis. A family history of mental health conditions can provide useful context, as can information about work, relationships, sleep, stress, and daily routines.

Diagnosis may also involve the use of standardized screening tools or questionnaires. These brief measures can help identify symptom patterns or assess severity and are commonly used for conditions such as depression, anxiety, stress-related disorders, and insomnia. While helpful, these tools are used alongside, not in place of, a full clinical evaluation.

Who can diagnose me?

Mental health diagnoses are typically made by clinicians with specialized training in assessment. This most often includes:

• Psychiatrists, who are medical doctors and can prescribe medication
• Clinical psychologists, who hold doctoral degrees and specialize in psychological assessment
• Other licensed mental health professionals, depending on location and scope of practice

In some cases, a primary care physician may make an initial diagnosis, especially for common conditions such as depression or anxiety, and refer a patient to a mental health specialist for further evaluation or treatment.

How is a mental health diagnosis made?

Once the information-gathering is complete, clinical experts align their diagnostic assessment with the comprehensive classification of mental health disorders known as the International Classification of Diseases (ICD) as well as the Diagnostic and Statistical Manual of Mental Disorders (DSM). These are updated as research and clinical data add to the knowledge base, and they list specific criteria for establishing the diagnosis of every recognized mental health condition.

The specificity of the criteria can be especially clinically helpful in distinguishing disorders that share symptoms. For example, major depression and bipolar disorder are both characterized by extensive periods of low mood, and depressed mood may be the presenting complaint of a person seeking help. But bipolar disorder can be diagnosed only after careful information-gathering reveals a history of one or more episodes of mania or its more subtle variant, hypomania. In such a case, as in all others, differential diagnosis is extremely important for determining the most helpful treatment.

Furthermore, symptoms of mental disorders can overlap those of physical conditions: for example, neural inflammation can create an array of psychiatric symptoms and has been linked to depression, obsessive-compulsive disorder, and other mental health conditions. As a result, a physical examination is often required to rule out physical problems that could be creating mental symptoms. In addition, laboratory tests may be helpful for screening out such possible causes as thyroid disease or drug use.

Receiving a diagnosis

It’s important to remember that receiving a mental health diagnosis is not necessarily a lifetime pronouncement. Like other illnesses, psychiatric disorders can vary in their duration and intensity, and many individuals recover fully from an episode of mental illness or experience sufficient alleviation of symptoms that they no longer meet the criteria for a diagnosis.

Even for chronic mental health conditions such as schizophrenia or bipolar disorder, the most effective interventions for mental health disorders usually involve education, lifestyle changes, and social support as well as medication and psychotherapy. It is increasingly the mark of modern care that, after an acute episode of illness, diagnosis and treatment involves helping people understand their own vulnerabilities so they can manage their lives in the most healthful ways possible.

Next steps

After a diagnosis is made, treatment planning is typically the next step. This may include psychotherapy, medication, lifestyle changes, or a combination of these approaches. For many people, treatment may also involve education about their condition, and strategies for managing stress, sleep, or relationships may be central to their recovery.
