Bipolar Disorder

Bipolar disorder, formerly called manic depression, is a mental illness that brings severe high and low moods and changes in sleep, energy, thinking, and behavior.

People who have bipolar disorder can have periods in which they feel overly happy and energized and other periods of feeling very sad, hopeless, and sluggish. In between those periods,  they usually feel normal. You can think of the highs and the lows as two "poles" of mood, which is why it's called "bipolar" disorder.

Understanding Bipolar Disorder: Symptoms

The primary symptoms of bipolar disorder are periods of elevated or irritable mood accompanied by dramatic increases in energy, activity, and thinking. The illness has two (bi) strongly contrasting phases (polar): 1) bipolar mania or hypo-mania and 2) depression. 1) Bipolar mania or hypo-mania symptoms include: Euphoria or irritability Increased energy and activity Excessive talk; racing thoughts Inflated self-esteem Unusual energy; less need for sleep Impulsivenes...

The word "manic" describes the times when someone with bipolar disorder feels overly excited and confident. These feelings can also involve irritability and impulsive or reckless decision-making. About half of people during mania can also have delusions (believing things that aren't true and that they can't be talked out of) or hallucinations (seeing or hearing things that aren't there). 

"Hypomania" describes milder symptoms of mania, in which someone does not have delusions or hallucinations, and their high symptoms do not interfere with their everyday life.

The word "depressive" describes the times when the person feels very sad or depressed. Those symptoms are similar to depression, a condition in which someone never has manic or hypomanic episodes. 

Most people with bipolar disorder spend more time in depressed phases than in manic phases.

What Are the Symptoms of Bipolar Disorder?

In bipolar disorder, the dramatic episodes of high and low moods do not follow a set pattern. Someone may feel the same mood state (depressed or manic) several times before switching to the opposite mood. These episodes can happen over a period of weeks, months, and sometimes even years.

How severe it gets differs from person to person and can also change over time, becoming more or less severe.

Symptoms of mania ("the highs"):

  • Excessive happiness, hopefulness, and excitement
  • Sudden changes from being joyful to being irritable, angry, and hostile
  • Restlessness
  • Rapid speech and poor concentration
  • Increased energy and less need for sleep
  • High sex drive
  • Making grand and unrealistic plans
  • Showing poor judgment
  • Drug and alcohol abuse
  • Becoming more impulsive

During depressive periods ("the lows"), a person with bipolar disorder may have:

  • Sadness
  • Loss of energy
  • Feelings of hopelessness or worthlessness
  • Not enjoying things they once liked
  • Trouble concentrating
  • Uncontrollable crying
  • Trouble making decisions
  • Irritability
  • Needing more sleep
  • Insomnia
  • Appetite changes that make them lose or gain weight
  • Thoughts of death or suicide
  • Attempting suicide

Who Gets Bipolar Disorder?

When someone gets bipolar disorder, it usually starts when they're a young adult. It can happen earlier, often along with ADHD. Bipolar disorder can run in families. 

Men and women are equally likely to get it.  Women are somewhat more likely than men to go through "rapid cycling," which is having several distinct mood episodes within a year. Women also tend to spend more time depressed than men with bipolar disorder. 

Many people with the condition abuse alcohol or other drugs. People with seasonal depression and certain anxiety disorders, like post-traumatic stress disorder (PTSD), are also more likely to have bipolar disorder.
