The symptoms of bipolar disorder

What are the symptoms of bipolar disorder?

Bipolar disorder is a mood disorder. Everyone has ups and downs in their moods but if you have bipolar disorder your mood swings are much more extreme.

For most people with bipolar disorder, manic and depressive moods alternate. You may cycle between the moods, or have periods of stability between them.

It’s important to get a diagnosis if you think you may have bipolar disorder. While a manic high can feel great at the time, it can cause you to act in ways that are damaging to you, your life and your relationships. And in a severe depressive state, it can be next to impossible to carry on with life and you may be at risk of suicide.

Bipolar symptoms: a manic episode

If you experience a manic high you may feel wonderful, ecstatic and energetic. You may not know anything is wrong until afterwards, when you look back.

You may:

  • Talk too fast
  • Need little sleep
  • Be full of energy
  • Feel restless
  • Be unable to control your racing thoughts
  • Be overconfident
  • Act impulsively
  • Take risks
  • Behave aggressively or argumentatively
  • Do things you wouldn’t usually, like behaving sexually promiscuously, spending a lot of money, using drugs or alcohol, gambling, or making unwise decisions
  • Feel more irritable than usual
  • Struggle to focus or concentrate
  • Be much more social than usual

Bipolar symptoms: a depressive episode

If you are in a period of depression, on the other hand, life feels bleak.

You may:

  • Feel extremely tired or sluggish
  • Cry a lot without reason
  • Feel emotionally empty
  • Feel guilty
  • Feel worthless
  • Lose interest in doing things you usually enjoy
  • Feel hopeless or negative
  • Lack confidence
  • Sleep and eat irregularly
  • Gain or lose weight
  • Find it hard to concentrate
  • Feel suicidal
  • Be forgetful
  • Find it hard to make decisions

Some people also experience psychosis: during mania your sense of importance or your suspicions may develop into delusions; in a depressive episode you may start seeing and hearing things that others don’t (hallucinations) or have delusions.

Getting treatment

People with bipolar disorder often find it hard to seek treatment but getting professional help can make a huge difference.
