screening for depression

Overview

Screening for depression is a simple set of questions that help a healthcare professional identify whether you might have depression. It is not a diagnosis, but a first step toward getting support and treatment.

Yes. Depression is one of the most common mental health conditions worldwide. Many people experience it at some point in their lives.

Depression can affect anyone, regardless of age, gender, or background. It often first appears in late teens or young adulthood, but it can also affect children, older adults, and people of all ages.

Symptoms

Common symptoms

• Feeling sad, empty, or hopeless most of the time
• Loss of interest in activities you used to enjoy
• Changes in appetite or weight
• Sleep problems, like trouble falling asleep or sleeping too much
• Feeling tired or low on energy
• Difficulty concentrating, remembering, or making decisions
• Feeling worthless, guilty, or overly self-critical
• Thoughts of death or self-harm

Symptoms in children

• Irritability or anger rather than sadness
• Clinging to parents or avoiding school
• Complaining of stomach aches or headaches
• Poor school performance or withdrawal from friends

Symptoms in older adults

• Memory problems or slowed thinking
• Loss of interest in hobbies or socializing
• Unexplained aches and pains
• Fatigue, sleep problems, or appetite changes
• Feelings of hopelessness or wanting to give up

Causes

Main causes

• Chemical changes in the brain
• Genetic factors – depression can run in families
• Stressful life events, like loss, relationship problems, or financial difficulties
• Medical conditions or chronic pain
• Certain medications (but never stop medication without talking to your doctor)

Risk factors

• Family history of depression
• Past history of depression or other mental health conditions
• Trauma or abuse
• Social isolation or lack of support
• Substance use
• Chronic illness or disability

When to see a doctor

See a doctor urgently if:

• If you have thoughts of self-harm or suicide
• If you feel unable to keep yourself safe

Book a routine appointment if:

• If you have felt sad, hopeless, or uninterested in things for more than two weeks
• If your mood is interfering with work, school, or relationships
• If family or friends have encouraged you to seek help

Diagnosis

A healthcare professional, such as your primary care doctor or a mental health specialist, will ask you questions about your mood, thoughts, sleep, appetite, and daily functioning. They may also use a short paper or digital questionnaire.

Tests that may be done

• Questionnaires about your symptoms, such as the PHQ-9 (Patient Health Questionnaire)
• Blood tests to rule out medical conditions like thyroid problems or vitamin deficiencies
• A thorough discussion of your medical and family history

What to expect at your appointment

The appointment is confidential. Be honest about how you are feeling – this helps the professional give you the best possible support. If needed, they may refer you to a mental health specialist for a more detailed assessment.

Treatment

Depression is treatable. Treatment usually involves talking therapies, lifestyle changes, and sometimes medication. Your doctor will work with you to create a plan that fits your unique situation.

Self-care at home

• Establish a regular sleep schedule
• Move your body regularly – even a short walk helps
• Stay connected with friends, family, or support groups
• Break large tasks into small, manageable steps
• Set realistic daily goals and celebrate small wins

Medical treatments

Medical treatments for depression include talking therapies such as cognitive behavioral therapy (CBT) or interpersonal therapy. For moderate to severe depression, antidepressant medications may be offered. Always discuss the benefits and risks with your doctor. They can help you find the most suitable treatment. Never stop a prescribed medication without medical advice.

When is surgery considered?

Surgery is not a treatment for depression.

Living with this condition

Living with depression means taking things one day at a time. Some days will be harder than others, and that's okay. Keep your doctor visits, follow your treatment plan, and remind yourself that healing is a gradual process.

Lifestyle tips

• Keep a journal to track your moods and triggers
• Set a daily routine
• Spend time outdoors, if possible
• Limit alcohol and avoid recreational drugs
• Practice relaxation techniques like deep breathing or mindfulness

Diet and exercise

Eating a balanced diet and staying physically active can support your overall well-being. There is no 'perfect' diet, but regular meals and healthy snacks can help stabilize your energy and mood. Aim for gentle activities you enjoy, like walking, swimming, or yoga.

Mental health and emotional wellbeing

Depression can make you feel isolated, frustrated, or guilty. It is important to remember that these feelings are part of the condition, not your fault. Seeking help is a sign of strength, not weakness.

Prevention

Depression cannot always be prevented, but early screening and timely support can reduce the chance of severe episodes. Building healthy coping skills and strong social connections can also help protect your mental health.

Screening programmes

Regular screening for depression is recommended for adults, especially those with risk factors or chronic health conditions. Ask your healthcare provider about screening during routine check-ups.

Complications

If left untreated

• Worsening symptoms that affect work, school, or relationships
• Increased risk of self-harm or suicide
• Physical health problems like heart disease, weakened immune system, or chronic pain
• Substance use as a coping mechanism

Long-term outlook

With proper support, most people with depression recover or learn to manage their symptoms. Treatment may take time, but improvement is possible. You deserve help, and it can make a real difference.
