Depression
(Major Depressive Disorder)
Understanding Depression:
A Clinical Mood Disorder
Depression is a clinical mood disorder that affects far more than mood alone. It can disrupt motivation, energy, concentration, sleep, and physical health, affecting every aspect of a person's life, from work and study performance to relationships and personal wellbeing. Our psychiatrists help patients across Australia clarify their diagnosis, identify contributing factors, and develop personalised treatment plans to restore their quality of life.
Consult With our Psychiatrist
Our psychiatrists provide assessment, diagnosis, and treatment planning for a range of mental health conditions.

Key Facts about Depression
Around 1 in 7 Australians will experience depression at some point in their lifetime.
Depression is one of the leading causes of disability worldwide.
Depression often occurs alongside other conditions such as anxiety, ADHD, or PTSD.
Depression is treatable, and treatment is tailored to the individual.
Some people do not respond fully to initial treatments. Where that happens, other options can be considered, including transcranial magnetic stimulation.
Symptoms of Depression
Our telehealth and in-person psychiatry services across Australia provide a convenient, accessible option for individuals seeking help managing these symptoms.
Persistent low mood
Loss of interest or enjoyment
Fatigue or low energy
Sleep disturbance
Changes in appetite
Difficulty concentrating
Feelings of hopelessness, guilt, or worthlessness
Indecisiveness and negative thinking
Social withdrawal
Thoughts of death or self-harm
Causes and Risk Factors
The exact cause of depression is not fully understood. Research suggests it usually develops from a combination of biological, psychological, and life factors rather than a single cause.
Several factors may increase the likelihood of developing depression.
It is important to note that depression is not a sign of weakness or a character flaw, and it cannot simply be overcome by "trying harder."

Biological Factors
Depression often runs in families. Brain chemistry, genetic vulnerability, and physical health conditions can all contribute to the development of depressive symptoms.

Psychological Factors
Thinking patterns, personality traits, and coping styles may influence how a person responds to stress and adversity, increasing vulnerability to depression.

Life Factors
Certain life experiences may increase risk, such as:
- Stressful life events
- Trauma
- Relationship difficulties
- Chronic illness
How is Depression Diagnosed?
Depression is diagnosed through a comprehensive clinical assessment conducted by a qualified clinician, usually a psychiatrist.
There is no single test for depression. Symptoms can overlap with other conditions, including anxiety disorders, ADHD, PTSD, bipolar disorder, sleep disorders, and substance use disorders, so an accurate diagnosis is essential to effective treatment.
A typical depression assessment may include:
Clinical Interview
The psychiatrist discusses current symptoms, personal history, and how mood difficulties affect work, study, relationships, and daily life.
Treatment History Review
Previous medications, therapies, and treatment responses are reviewed to understand what has and hasn't worked.
Assessment of Co-occurring Conditions
Other mental health conditions such as anxiety, ADHD, PTSD, sleep disorders, and bipolar disorder may be assessed because they can overlap with depression.
Functional Assessment
Understanding the impact of symptoms on work, study, relationships, and everyday functioning helps shape a targeted treatment plan.

Treatment Options for Depression
Depression treatment usually involves a combination of strategies tailored to the individual's needs.
Medication
Medication may help reduce symptoms and improve functioning for some individuals with depression. A psychiatrist will determine whether medication is appropriate, with treatment carefully monitored and adjusted over time.
Psychological Therapies
Psychological support may help individuals address negative thinking patterns, process difficult experiences, and build coping strategies.
Examples may include:
- Cognitive behavioural therapy (CBT)
- Trauma-informed therapies
- Supportive psychotherapy
Lifestyle and Recovery Strategies
Daily structure and supportive habits may help improve mood and functioning.
These may include:
- Sleep optimisation
- Stress management
- Regular physical activity
- Social and occupational recovery
Treatment plans are personalised and may change over time.
When Standard Treatments Have Not Worked
Some individuals continue to experience significant symptoms despite multiple treatment attempts. This is known as treatment-resistant depression, and it may occur due to an incomplete diagnosis, unrecognised co-occurring conditions, biological factors, or treatment mismatch.
Our psychiatrists regularly manage treatment-resistant depression and collaborate on complex cases to ensure thoughtful, individualised care.

Transcranial Magnetic Stimulation (TMS)
A non-invasive treatment that uses magnetic stimulation to target brain networks involved in mood regulation.

Esketamine Therapy
A newer treatment option for selected patients with treatment-resistant depression, administered under specialist supervision within a structured treatment program.
These options are considered only after careful assessment and discussion.
