Depression — symptoms, causes and help.

Depression is not a sign of weakness. It is a condition that can arise from a combination of long-term stress, life changes, losses or biological factors. Depression is common and treatable.

Symptoms

Depression is a condition in which low mood or loss of interest lasts for at least several weeks and affects everyday life. Symptoms can differ from person to person.

How common is depression

Depression affects millions of people

Depression is one of the most common mental health conditions in the world. It does not mean that you are weak — it means you have been under too much strain for too long.

280M+

people experience depression every year (WHO)

5–8%

of European adults experience symptoms of depression each year

Every 5th

person may experience a depressive episode during their lifetime

Causes

Long-term stress

Depression often develops from the combined effect of chronic stress and overload

Major life changes

Losses, divorce, job loss or other major life changes

Earlier difficulties

Previous mental health difficulties increase the risk of depression

Biological factors

Genetic predisposition and brain chemistry influence the development of depression

Social factors

Loneliness, relationship problems and a lack of social support

Often a combination of several factors

Depression does not usually arise from a single cause — most often it is the result of several factors acting together

Treatment and therapy

Depression is a treatable condition

Recovery is a process — step by step it is possible to restore balance and a sense of joy in life. This is not simply a bad mood — it is a condition that lasts a longer time and needs attention.

Psychotherapy

CBT and supportive counselling

Cognitive behavioural therapy (CBT) is the most evidence-based treatment for depression. It helps to change negative thought patterns.

Coping skills

Making conscious lifestyle changes

In therapy you learn coping skills, stress management and how to create balance in everyday life.

Therapy outcomes

What people experience

Improved mood · better coping with stress · changing negative thought patterns · restored self-confidence

When to seek help

When should you turn to a psychologist?

Seeking help does not mean giving up. It means you are ready to take care of yourself.

Sadness lasting more than 2 weeks

If low mood lasts more than two weeks and does not ease, it is time to seek help

Everyday activities feel overwhelming

When ordinary life feels overwhelming and your energy has dropped to zero

A feeling of hopelessness

A sense that nothing will get better or that there is no future

A wish to withdraw

You have started to withdraw from loved ones and friends

Very negative thoughts

Thoughts become increasingly negative, or thoughts of self-harm arise

BRAIN CHEMISTRY

What happens in the brain during depression and burnout?

Depression is not a question of weakness or willpower — it is an imbalance in brain chemistry and the nervous system. In depression, the balance of neurotransmitters — the brain's "chemical messengers" — is often disrupted. It is not only about producing hormones, but also about how the brain passes on its message: the receptors, nerve connections and the balance between different systems.

Serotonin activity is lower

Less contentment. More anxiety. Sleep and eating problems. Serotonin regulates mood stability, sleep and appetite — when its level falls, you feel unsettled and irritable.

The dopamine system is "sluggish"

Reduced motivation. Difficulty enjoying activities that once brought pleasure. Dopamine is linked to the reward and motivation system — its decline explains why everything can feel pointless and monotonous during depression.

Noradrenaline levels are lower

Tiredness and lack of energy. Difficulty concentrating. Noradrenaline is responsible for alertness and attention — low levels explain why someone with depression feels a constant sense of heaviness and fogginess.

Endorphin activity has fallen

A person no longer feels a lift in mood from movement or laughter. Endorphins are the body's natural "painkillers and feel-good chemicals" — their decline means that even the activities that usually feel good no longer bring relief.

The good news is that we can influence brain chemistry. Movement raises endorphin and dopamine levels. Good-quality sleep restores the serotonin system. Social support and safe relationships activate oxytocin. Therapy helps to change the thought patterns that keep the stress system running — and, when needed, medication supports the restoration of neurotransmitter balance.

For loved ones

What can a loved one do to help someone with depression?

You don't have to be a perfect helper. It is enough to be present and caring.

Listen and take them seriously

Without judgement or pressure

Say: „I'm sorry things are so hard for you.“ · „I'm here for you.“ · Someone with depression needs understanding.

Help with practical things

Small acts make a big difference

Offer help with small chores · a walk together · accompanying them to the doctor. Depression makes simple things feel like a burden.

Encourage professional help

Supportively, not by pressuring

Offer to help book an appointment or to go along to the visit. It is important to do this supportively, not under pressure.
