What is the minimum duration required for a manic episode to classify as part of bipolar disorder?

A manic episode must last for at least seven days to be classified as part of bipolar disorder according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This duration is significant because it ensures that the elevated mood, increased energy, and other symptoms are sufficiently persistent and pervasive to distinguish a manic episode from shorter fluctuations in mood or brief reactive states that may not meet the criteria for mania. A minimum duration of seven days helps to solidify the diagnosis of a bipolar disorder, allowing for more effective treatment planning and monitoring of the individual’s mental health.
