Potential Causes of Depression

Depression arises from a multifaceted interplay of biological, psychological, and environmental factors:

• Genetics: A family history of depression can increase one’s risk.
• Neurochemical Imbalances: Changes in serotonin, dopamine, and norepinephrine levels can affect mood regulation.
• Personality: Individuals with low self-esteem or high sensitivity to stress may be more vulnerable.
• Life Circumstances: Bereavement, financial hardship, relationship issues, or major life transitions can trigger or exacerbate depressive episodes.
• Medical Conditions: Chronic illness, hormonal imbalances (e.g., thyroid dysfunction), or substance use can contribute to or mimic depressive symptoms.

It is important to remember that depression is not a sign of weakness or a character flaw. It is a medical condition that requires proper care.

Available Treatment Options

Depression is highly treatable, and most people experience improvement with the right support. At AO Psychology in Singapore, we offer personalised, evidence-based treatment to help individuals recover and thrive.

1. Psychological Therapy

• Cognitive Behavioural Therapy (CBT): Helps clients identify and restructure negative thought patterns and behaviours that sustain depression.
• Interpersonal Therapy (IPT): Focuses on improving relationship dynamics and social functioning, often impacted by depression.
• Psychodynamic Therapy: Explores underlying emotional conflicts and unresolved past experiences contributing to depressive symptoms.
• Mindfulness-Based Cognitive Therapy (MBCT): Combines mindfulness practices with CBT to prevent relapse in recurrent depression.

2. Medication

In moderate to severe cases, a psychiatrist may prescribe:

• Antidepressants (SSRIs, SNRIs, or atypical antidepressants)
• Medication is often used alongside therapy for greater effectiveness and closely monitored for side effects.

3. Lifestyle and Supportive Interventions

• Regular physical activity
• Adequate sleep and balanced nutrition
• Structured routines and goal setting
• Support groups and psychoeducation

AO Psychology takes a holistic and collaborative approach, considering each client’s background, preferences, and goals to create a tailored treatment plan.

Can depression be treated without medication?

Yes. Many individuals with mild to moderate depression benefit significantly from structured psychotherapy alone. A clinical psychologist can assess severity and recommend the most appropriate intervention plan.

How is depression different from feeling sad or stressed?

Sadness and stress are normal emotional responses to difficult situations and typically improve with time or changes in circumstances. Clinical depression, however, involves persistent low mood, reduced motivation, and changes in sleep, appetite, or thinking that last for weeks or longer. Depression interferes with daily functioning and may require structured psychological support.

Is depression common in Singapore?

Depression is one of the most prevalent mental health conditions globally, and Singapore is no exception. Factors such as workplace stress, academic pressure, caregiving demands, and social expectations may contribute to vulnerability. Early psychological assessment allows individuals to receive appropriate support before symptoms become more severe.

What causes depression?

Depression typically arises from a combination of biological, psychological, and environmental factors. These may include:

• Genetic predisposition
• Chronic stress or burnout
• Trauma or adverse childhood experiences
• Major life transitions
• Unhelpful thinking patterns
• Social isolation

A clinical psychologist assesses contributing factors to develop a personalised therapy plan.

Can depression affect physical health?

Yes. Depression can manifest physically through fatigue, headaches, gastrointestinal discomfort, changes in appetite, and sleep disturbances. Psychological distress and physical symptoms often interact, which is why a comprehensive assessment is important.

How long does therapy for depression take?

The duration of therapy varies depending on severity and complexity. Structured approaches such as Cognitive Behavioural Therapy (CBT) for depression may span 12–20 sessions. More complex or longstanding depression may require longer-term psychotherapy. Progress is reviewed regularly to ensure therapy remains appropriate and effective.

Is depression a sign of weakness?

No. Depression is a recognised psychological condition and not a character flaw. It reflects changes in mood regulation, cognitive processing, and stress response systems. Seeking professional support is a proactive step toward recovery.

Can adolescents and children experience depression?

Yes. Depression can occur in children and adolescents, though symptoms may present differently — such as irritability, withdrawal, academic decline, or behavioural changes. Early intervention by a clinical psychologist supports emotional development and long-term resilience.

What happens during a psychological assessment for depression?

A clinical psychologist will conduct a structured interview exploring mood history, symptom duration, stressors, medical background, and psychosocial factors. Standardised assessment tools may also be used. This process helps determine whether symptoms meet criteria for depressive disorders and informs an evidence-based treatment plan.

Can depression recur?

Yes. Some individuals may experience recurrent depressive episodes, especially during periods of stress. Psychotherapy equips individuals with coping strategies and relapse-prevention tools to reduce recurrence risk.
