What is depression?

Major Depressive Disorder (MDD), commonly known as depression, is a serious medical condition characterised by persistent low mood, loss of interest or pleasure, and reduced energy.

Depression can affect how a person thinks, feels, and functions day-to-day, often leading to disturbances in sleep, appetite, concentration, and self-esteem. It is distinct from ordinary sadness or grief—it involves a sustained change in mood lasting at least two weeks and significantly impairs quality of life and daily functioning.

What causes depression?

Behind depression lies a complex interplay of brain chemistry, hormones, stress, and environment — influencing how we think, feel, and connect with the world.

Depression arises from a complex interaction of biological, psychological, and social factors. Genetics, trauma, chronic stress, medical illness, and neurochemical changes in the brain can all play a role. While conventional antidepressants and psychotherapy are effective for many, some individuals experience treatment-resistant depression (TRD)—where symptoms persist despite multiple standard treatments.

Common symptoms of depression

Depression often involves a combination of emotional, cognitive, and physical symptoms.

Recognising depression is the first step in seeking help. Depression can look different for each person, but common symptoms may include:

  • Persistent sadness, emptiness, or hopelessness
  • Loss of interest or pleasure in daily activities
  • Low energy, fatigue, or sleep problems
  • Difficulty concentrating or making decisions
  • Changes in appetite or weight
  • Feelings of worthlessness or guilt
  • Suicidal thoughts in severe cases

How can we help

For many people, standard treatments like antidepressants or psychotherapy aren’t enough. At Anodyne, we offer treatments for people with treatment resistant depression.

Explore how ketamine can be used in treatment-resistant depression to help improve mood, relieve distress, and support long-term recovery.

Ketamine therapy

Ketamine therapy has been shown to improve depression, particularly in people with treatment resistant illness. Research has shown ketamine rapidly reduces depressive symptoms and suicidal thoughts, often within hours, providing a crucial window of safety and relief.
