What does it mean to have bipolar disorder?

Bipolar disorder means you experience extreme mood swings. At times you may feel euphoric and full of energy, while at other times you feel sad and drained.

Mania and depression – two sides of the disease

Manic episodes can give you a feeling of grandeur, increased self-confidence, and a lot of energy – often so much that you sleep very little and make impulsive decisions. Conversely, depressive episodes can make it difficult to find joy in things you normally enjoy, and lead to fatigue, guilt, and low self-esteem.

Symptoms you should be aware of

It is important to know the symptoms so that you or your relatives can react early. The disease often debuts in adolescence or early adulthood.

In mania, you may experience:

  • Excessive energy and restlessness
  • Less need for sleep
  • Loud speech and racing thoughts
  • Increased risk appetite

With depression, you can feel it:

  • Depression and hopelessness
  • Lack of energy
  • Sleep problems
  • Suicidal thoughts

What causes bipolar disorder?

There isn't one single cause. It's a combination of hereditary, biological, and environmental factors.

Genetics and brain chemistry play a role

Bipolar disorder is more common if you have a close relative with the illness. In addition, it is known that the brain's neurotransmitters such as dopamine and serotonin play a role. Stress, sleep disturbances, and substance abuse can trigger the illness in predisposed individuals.

How is the diagnosis made?

This requires a thorough assessment of both symptoms and history.

Conversation and observation

The doctor will often ask a series of questions about your symptoms, sleep patterns, thoughts, and behavior. Sometimes, relatives are also involved to get a broader picture. It is important that you are honest and open so that the doctor can help you in the best possible way.

How is bipolar disorder treated?

Treatment often consists of medication and psychological support. It's about finding balance and stability in everyday life.

Medication and therapy

Mood-stabilizing medication is the cornerstone of treatment. In addition, talk therapy can help you understand your patterns and learn to manage stress and early signs of relapse. For many, the treatment is lifelong, but that doesn't mean you can't live a good life.

What is it like to live with bipolar disorder?

With the right support and knowledge, it is possible to live a meaningful and active life with bipolar disorder.

It is important to get to know yourself and your symptoms so that you can react quickly if something changes. Many people find that structure in everyday life, good sleep and avoidance of stress are important tools.

What can you do yourself?

You yourself play a big role in the treatment. It is about taking responsibility and taking the disease seriously - but also about giving yourself space to live.

  • Keep your treatment appointments
  • Take your medicine as prescribed
  • Get enough sleep and eat regularly
  • Share your thoughts with someone you trust

If you experience mood swings that affect your daily life, or if your relatives express concern, it is important to talk to a doctor.
