In bipolar disorder, manic episodes alternate with periods of emotional lows, which are known as depressive episodes.
Signs of a depressive episode may include:
Sadness, anxiety, or a feeling of emptiness
Feelings of guilt, feeling worthless, or feeling helpless
Lack of interest in activities that were once enjoyable, such as sex
Trouble with concentration or memory
Restlessness or irritability
Excessive sleeping or insomnia
Changes in appetite or weight
Pain or other physical symptoms not explained by an illness or injury
Thoughts of death, or suicidal thoughts or attempts
A diagnosis of depressive episodes is made if at least five of these symptoms are present for most of the day, nearly every day, for two weeks or longer.
