Bipolar disorder is a mental health condition characterized by extreme mood swings, including emotional highs (mania or hypomania) and lows (depression). These mood changes can affect sleep, energy levels, and the ability to think clearly. People with bipolar disorder may experience periods of intense activity and euphoria, followed by feelings of sadness and hopelessness. The exact cause of bipolar disorder is not fully understood, but it is believed to involve a combination of genetic, biochemical, and environmental factors. Treatment often includes a combination of medication, such as mood stabilizers, and psychotherapy, which can help individuals manage their symptoms and improve their quality of life.
