Distractibility, can’t concentrate well
Little sleep needed
Unrealistic beliefs in one’s abilities and powers
Poor judgment
Spending sprees
A lasting period of behavior that is different from usual
Increased sexual drive
Abuse of drugs, particularly cocaine, alcohol, and sleeping medications
Provocative, intrusive, or aggressive behavior
Denial that anything is wrong A manic episode is diagnosed if elevated mood occurs with three or more of the other symptoms most of the day, nearly every day, for 1 week or longer. If the mood is irritable, four additional symptoms must be present.
Signs and symptoms of depression (or a depressive episode) include:Lasting sad, anxious, or empty mood
Feelings of hopelessness or pessimism
Feelings of guilt, worthlessness, or helplessness
Loss of interest or pleasure in activities once enjoyed, including sex
Decreased energy, a feeling of fatigue or of being “slowed down”
Difficulty concentrating, remembering, making decisions
Restlessness or irritability
Sleeping too much, or can’t sleep
Change in appetite and/or unintended weight loss or gain
Chronic pain or other persistent bodily symptoms that are not caused by physical illness or injury
Thoughts of death or suicide, or suicide attempts A depressive episode is diagnosed if five or more of these symptoms last most of the day, nearly every day, for a period of 2 weeks or longer.
A mild to moderate level of mania is called hypomania. Hypomania may feel good to the person who experiences it and may even be associated with good functioning and enhanced productivity. Thus even when family and friends learn to recognize the mood swings as possible bipolar disorder, the person may deny that anything is wrong. Without proper treatment, however, hypomania can become severe mania in some people or can switch into depression.
Sometimes, severe episodes of mania or depression include symptoms of psychosis (or psychotic symptoms). Common psychotic symptoms are hallucinations (hearing, seeing, or otherwise sensing the presence of things not actually there) and delusions (false, strongly held beliefs not influenced by logical reasoning or explained by a person’s usual cultural concepts). Psychotic symptoms in bipolar disorder tend to reflect the extreme mood state at the time. For example, delusions of grandiosity, such as believing one is the President or has special powers or wealth, may occur during mania; delusions of guilt or worthlessness, such as believing that one is ruined and penniless or has committed some terrible crime, may appear during depression. People with bipolar disorder who have these symptoms are sometimes incorrectly diagnosed as having schizophrenia, another severe mental illness.
It may be helpful to think of the various mood states in bipolar disorder as a spectrum or continuous range. At one end is severe depression, above which is moderate depression and then mild low mood, which many people call “the blues” when it is short-lived but is termed “dysthymia” when it is chronic. Then there is normal or balanced mood, above which comes hypomania (mild to moderate mania), and then severe mania.
