What is currently known about the causes of bipolar disorder?

The understanding of bipolar disorder has evolved, revealing that its causes are multifaceted. Current knowledge indicates that while the exact cause remains unclear, there is substantial evidence suggesting a genetic component plays a significant role in the disorder. Research has shown that individuals with a family history of bipolar disorder are at an increased risk, indicating a hereditary influence.

Additionally, this disorder does not stem from a singular source but is thought to arise from the interplay between genetic susceptibility and other factors such as biochemical imbalances in the brain. Therefore, option C accurately reflects the prevailing view that while the specific causes are not fully understood, genetics is a critical factor alongside other biological, environmental, and psychological elements that may contribute to the development of the disorder. Understanding these dimensions is essential for developing therapeutic approaches and managing bipolar disorder effectively.
