Bipolar disorder is a chronic brain illness. It causes significant changes in mood, energy, and functional capacity. These changes range from deep depressive episodes to periods of intense excitement, called mania or hypomania. Understanding bipolar disorder helps to better recognize it and seek the necessary help.

What is Bipolar Disorder?

The term “bipolar disorder” refers to a complex condition. People living with this illness experience alternating moods, varying between depressive phases, manic or hypomanic phases, and sometimes periods of stable mood.

1) Depressive phases lead to profound sadness, loss of interest, and low energy.

2) Manic phases are characterized by excessive euphoria, irritability, increased energy, and reduced need for sleep.

3) Hypomanic phases are similar to mania but with less intensity.

Causes and Risk Factors for Bipolar Disorder

The origins of bipolar disorder often involve a combination of factors. Genetics play a significant role: a family history of the illness increases the risk. However, the presence of specific genes does not guarantee the development of the disorder. Imbalances in brain chemicals, such as neurotransmitters, also contribute to the emergence of symptoms. Stressful life events, trauma, or substance abuse can trigger episodes in vulnerable individuals. The interaction between these different factors makes bipolar disorder complex to understand.

Symptoms and Signs of Bipolar Disorder

Bipolar disorder manifests through distinct mood episodes. Each episode type presents specific signs.

1) Depressive Episodes

• Persistent sadness or loss of interest in activities.
• Intense fatigue or lack of energy.
• Sleep disturbances (insomnia or hypersomnia).
• Changes in appetite or weight.
• Feelings of guilt or worthlessness.
• Difficulty concentrating or making decisions.
• Thoughts of death or suicide.

2) Manic Episodes

• Abnormally elevated, euphoric, or irritable mood.
• Increased energy and activity.
• Decreased need for sleep.
• Rapid and incessant speech.
• Racing thoughts (flight of ideas).
• Increased self-esteem or grandiose ideas.
• Impulsive or risky behaviors (excessive spending, sexual recklessness).

3) Hypomanic Episodes

These present manic symptoms, but with less intensity. The person generally does not lose touch with reality. The consequences on daily life remain less severe than during a full manic episode.

Mixed Episodes

A person may experience symptoms of depression and mania simultaneously. For example, a depressed mood coexists with an excess of energy or agitation.

Diagnosis of Bipolar Disorder

A qualified healthcare professional, such as a psychiatrist, establishes the diagnosis of bipolar disorder. The process relies on a thorough clinical evaluation. It includes a detailed interview with the person and often with their close relatives. The practitioner seeks to identify the presence of mood cycles. They examine the nature, frequency, and duration of episodes. They rule out other medical conditions or mental disorders that could cause similar symptoms. The use of specific diagnostic criteria, such as those from the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), aids in accurate diagnosis.

Treatments and Management of Bipolar Disorder

The management of bipolar disorder requires a long-term approach. It combines several strategies. Medication is the cornerstone of management. Mood stabilizers are the first line of treatment. They help prevent manic and depressive episodes. Antidepressants can be used cautiously during depressive phases, often in combination with a stabilizer to avoid inducing mania. Antipsychotics can treat mania or bipolar depression, especially when psychotic symptoms are present.

Psychotherapy, especially cognitive-behavioral therapy (CBT), helps individuals manage stress. It also enables them to identify triggers and develop coping strategies. Illness education is essential. It helps individuals and their families better understand the disorder and recognize warning signs. Establishing a regular routine, managing sleep, and engaging in physical activity also contribute to mood stabilization.

Recent Scientific Advances in Bipolar Disorder

Research on bipolar disorder is continuously progressing. In the first half of 2025, efforts have focused on several areas. Genetic studies continue to better define subtypes of bipolar disorder, identifying specific markers for more targeted treatment approaches. New generations of mood stabilizers and antipsychotics are in clinical trials, promising more favorable side effect profiles. Research is also interested in non-invasive brain stimulation (such as rTMS or tDCS) for treatment-resistant cases. Finally, digital applications and connected tools are exploring real-time symptom monitoring, offering the possibility of faster preventive interventions.

Prevention of Bipolar Disorder

The onset of bipolar disorder itself cannot be prevented. However, several strategies help reduce the frequency and severity of episodes. Early diagnosis and regular treatment are crucial. The person must strictly adhere to their medication treatment plan and regularly follow their psychotherapy. Learning to identify warning signs of an impending episode also helps. Healthy lifestyle habits, such as regular sleep, a balanced diet, and stress management, contribute to stability. Avoiding the consumption of psychoactive substances (drugs, alcohol) remains essential, as these substances can trigger or worsen mood episodes.

Living with Bipolar Disorder

Living with bipolar disorder requires adaptation and perseverance. The journey often involves continuous learning about one’s illness. Adherence to treatment is fundamental. Strong social support, whether from family, friends, or support groups, also plays a key role. Many people lead full and productive lives, learning to manage their symptoms and maintain their well-being. Open communication with healthcare professionals and loved ones helps manage challenges. It is important to remember that bipolar disorder is a manageable illness. Appropriate treatment stabilizes mood and significantly improves the quality of life.

Frequently Asked Questions (FAQ)

Is bipolar disorder a rare mental illness?

No, bipolar disorder affects approximately 1 to 2% of the world’s population, making it a relatively common mental illness.

Can bipolar disorder be cured?

Bipolar disorder is a chronic illness. It generally does not disappear in the sense of a cure. However, appropriate treatment can stabilize mood and manage symptoms. People can live stable and productive lives.

Are there different types of bipolar disorder?

Yes, the main types are bipolar I disorder (characterized by at least one manic episode), bipolar II disorder (with hypomanic and major depressive episodes), and cyclothymic disorder (milder but chronic mood fluctuations).

How to distinguish bipolar depression from unipolar depression?

Bipolar depression includes episodes of mania or hypomania, which are absent in unipolar depression. Diagnosis requires a complete clinical history to identify these mood variations. Recognizing these episodes helps make the correct diagnosis.

What to do in case of an acute manic or depressive crisis?

In case of an acute crisis, it is crucial to immediately contact a healthcare professional. Temporary hospitalization may be necessary to ensure the person’s safety and stabilize their mood with a rapid adjustment of treatment.
