What should you know about DSM-5 depression?

DSM-5 refers to a diagnostic manual used by mental health professionals. It describes a depressive episode through symptoms such as changes in sleep, appetite, energy, concentration, movement, self-worth, and thoughts about death. A clinician considers the overall pattern, how long it has been present, its effect on work or relationships, and whether another medical condition, medicine, substance, or mood pattern better explains it. Feeling anxious, irritable, fatigued, or unable to sleep can occur alongside depression, but any one symptom does not establish the diagnosis.

Assessment is a conversation rather than a single laboratory test. The clinician may ask about previous episodes, family history, physical health, medicines, alcohol or drugs, and safety at home.

Arrange an appointment with a general practitioner or mental health professional if low mood, reduced interest, or related changes are interfering with ordinary activities. Before the visit, note changes in sleep, appetite, energy, concentration, and functioning, along with medicines and substances you use. Treatments may include talking therapy, lifestyle support, medicine, or a combination, chosen with attention to your symptoms and preferences. Keep follow-up appointments so response and side effects can be reviewed.

Seek urgent help now if you are thinking about suicide, self-harm, harming someone else, or cannot keep yourself safe. Contact local emergency services or go to an emergency department, and stay with a trusted person while help is arranged. Urgent assessment is also appropriate for severe confusion, extreme agitation, or several days of very little sleep with unusually high energy or risky behaviour.

Ask which symptoms are shaping the assessment, what other causes should be checked, which treatment options fit your situation, and how quickly to arrange follow-up if your mood or safety changes.
