Feeling low or down is a natural part of life that everyone experiences at times. But when these feelings persist, deepen, and start to impact daily functioning, it may indicate clinical depression. Understanding the difference between sadness and depression, the biological and environmental factors involved, and the various types of depression can help you recognise when to seek support and how treatment can help to provide psychological support in Brisbane.
Sadness vs. Clinical Depression: Understanding the Difference
Sadness: A Normal Emotion
Sadness is an emotional response to a specific event—such as the loss of a loved one, a setback, or disappointment. It is usually temporary and fluctuates over time. While sadness can be painful, it does not typically interfere significantly with a person’s ability to carry out daily activities or maintain relationships.
Clinical Depression: A Medical Condition
Clinical depression, or Major Depressive Disorder (MDD), is a mental health condition characterised by persistent and intense feelings of sadness or emptiness lasting for at least two weeks. Depression impacts how a person thinks, feels, and behaves and can cause a range of emotional and physical problems.
Key symptoms of depression include:
- Persistent low mood or feelings of hopelessness
- Loss of interest or pleasure in activities once enjoyed
- Significant changes in appetite or weight
- Sleep disturbances (insomnia or oversleeping)
- Fatigue or loss of energy
- Difficulty concentrating or making decisions
- Feelings of worthlessness, guilt, or self-blame
- Thoughts of death or suicide
Unlike sadness, these symptoms interfere with everyday functioning and quality of life.
The Complex Causes of Depression: Brain Chemistry, Genetics, and Environment
Depression results from a complex interplay of biological, psychological, and social factors:
Brain Chemistry
Neurotransmitters—chemical messengers in the brain such as serotonin, dopamine, and norepinephrine—play a crucial role in mood regulation. Imbalances or disruptions in these chemicals can contribute to depressive symptoms.
Genetics
Having a family history of depression increases the risk, indicating that genetic factors influence vulnerability. However, no single “depression gene” exists; rather, multiple genes combined with environmental factors contribute to risk.
Environment and Life Events
Stressful or traumatic experiences such as abuse, neglect, loss, chronic illness, financial difficulties, or social isolation can trigger or exacerbate depression. Environmental factors may influence brain chemistry and gene expression through epigenetic mechanisms.
Psychological Factors
Personality traits such as low self-esteem or high levels of neuroticism can also increase susceptibility. Negative thinking patterns and maladaptive coping styles often contribute to the onset or maintenance of depression.
Types of Depression: More Than Just One Condition
Depression manifests in various forms, each with unique characteristics:
1. Major Depressive Disorder (MDD)
This is the most well-known type, involving severe symptoms that last for at least two weeks and significantly impair functioning.
2. Persistent Depressive Disorder (Dysthymia)
A chronic form of depression with less severe but long-lasting symptoms (two years or more). It often coexists with other mental health disorders.
3. Situational Depression (Adjustment Disorder with Depressed Mood)
Depression that arises in response to a specific life event or change. Symptoms tend to resolve once the individual adjusts or the situation improves.
4. Bipolar Depression
Depressive episodes that occur as part of bipolar disorder, alternating with periods of mania or hypomania characterised by elevated mood, energy, and activity.
5. Postpartum Depression
A form of depression that affects some women after childbirth, involving mood swings, fatigue, and feelings of hopelessness.
6. Seasonal Affective Disorder (SAD)
Depression linked to changes in seasons, usually occurring during winter months due to reduced sunlight exposure.
When to Seek Professional Help
It’s important to seek help if:
- Symptoms persist for more than two weeks
- Depression interferes with work, relationships, or self-care
- You experience thoughts of self-harm or suicide
- You notice changes in appetite, sleep, or energy levels
- You feel overwhelmed or unable to cope
Early intervention improves outcomes and can prevent symptoms from worsening.

How Psychologists Help Treat Depression
Psychologists provide evidence-based treatments tailored to individual needs, including:
Cognitive Behavioural Therapy (CBT)
CBT helps identify and challenge negative thinking patterns and behaviours that contribute to depression. Clients learn coping skills to manage symptoms and prevent relapse.
Interpersonal Therapy (IPT)
IPT focuses on improving interpersonal relationships and social functioning, which can have a strong impact on mood.
Mindfulness-Based Cognitive Therapy (MBCT)
Combines cognitive therapy techniques with mindfulness strategies to reduce rumination and prevent relapse.
Psychodynamic Therapy
Explores underlying unconscious conflicts and past experiences contributing to depression.
Behavioural Activation
Encourages re-engagement with pleasurable or meaningful activities to improve mood.
Medication and Multidisciplinary Care
While psychologists do not prescribe medication, they often work alongside psychiatrists or GPs who may prescribe antidepressants. Combining therapy with medication can be effective for moderate to severe depression.
Additionally, lifestyle interventions such as regular exercise, healthy nutrition, and social support play important roles in recovery.
