Bipolar disorder is a mood disorder involving episodes of elevated or expansive mood (mania or hypomania) and episodes of depression, with periods of stable mood in between. During elevated episodes, a person may experience racing thoughts, reduced need for sleep, increased energy and activity, inflated confidence, rapid speech, and impulsive decisions around spending, work or relationships. Depressive episodes mirror major depression, with low mood, exhaustion, loss of interest, and sometimes suicidal thoughts.

Bipolar disorder affects around one in fifty Australians. It typically emerges in late adolescence or early adulthood, and on average it takes years from first symptoms to accurate diagnosis, often because people seek help during depression while the elevated episodes go unrecognised or are remembered as simply good times.

Types of bipolar disorder

• Bipolar I: at least one full manic episode, usually with depressive episodes as well; mania can be severe and may include psychotic features
• Bipolar II: episodes of hypomania (a milder elevation) alternating with often prolonged and disabling depressive episodes
• Cyclothymic disorder: chronic fluctuation between milder hypomanic and depressive symptoms

Why accurate diagnosis matters

Bipolar depression is frequently misdiagnosed as ordinary depression, and treating it with antidepressants alone can be ineffective or even trigger mood elevation and cycling. A careful psychiatric assessment, including a detailed history of past mood episodes and often input from family with your consent, is essential to getting treatment right. This is one of the areas where specialist psychiatric expertise makes the greatest difference.

Treatment and staying well

Bipolar disorder is a lifelong condition, and it is highly manageable. The foundation of treatment is mood-stabilising medication, carefully chosen and monitored by your psychiatrist. Psychological therapy adds substantial benefit, helping you recognise early warning signs, protect sleep and routine, manage stress, and reduce relapse. Regular psychiatric review keeps treatment tuned to your life, and your GP remains a key partner in monitoring physical health alongside. With good management, most people with bipolar disorder live full, stable and rewarding lives.
