Signs Of Bipolar Depression In Teens

Medically Reviewed
Last Medically Reviewed on: October 25, 2022

Bipolar depression is a mood disorder in which people experience severe mood swings that alternate between bouts of depression and episodes of mania. It can be difficult to correctly diagnose mood disorders in teens because they often struggle with other mental health issues, such as anxiety and eating disorders. Signs of bipolar depression often emerge during the teenage years while the brain is still developing and is more vulnerable to stress. Signs of a manic episode include reckless behavior such as overspending and substance abuse, and some signs of a depressive episode include disrupted sleeping patterns and suicidal thoughts and ideas.

What Is Bipolar Depression

Also known as bipolar disorder and manic depression, bipolar depression is a type of depression that emerges between 15-30 years of age. The cause of the bipolar disorder is unknown, but it often runs in families and can be triggered by stress or traumatic events. 

People with bipolar disorder experience depressive and manic episodes, each lasting for at least one week. There are two types of bipolar depression–Bipolar I is defined by more extreme bouts of depression and mania, while Bipolar II is defined by bouts of intense depression and mild mania, also known as hypomania.

Less Need For Sleep

Teens have lots of energy during manic episodes and won’t need to sleep much. Many teens can experience insomnia during manic episodes and won’t need to sleep for days at a time. Although teens may not be aware of this right away, the sleep deficit caused by manic episodes can affect their physical well-being, causing digestive issues and other physical symptoms. During manic episodes, teens can become unusually excited, optimistic, talkative, and productive. Teens may also display reckless behaviors such as overspending, being sexually promiscuous, or throwing caution to the wind. In more extreme episodes, teens can have delusions of grandeur, become paranoid, or even experience psychotic episodes that require hospitalization. 


Feelings Of Despair and Hopelessness

During depressive episodes, teens often experience intense feelings of loneliness, despair, and hopelessness. It can be difficult for them to get out of bed in the morning or feel motivated to get things done. A depressive episode can be marked by fatigue, no matter how much sleep a teen gets, and an inability to feel pleasure or excitement. This absence of hope and lack of energy makes day-to-day life unmanageable, making it even more difficult for teens to thrive and keep up with their academic and social responsibilities. 

Unpredictable Mood Swings

Teens with bipolar disorder experience intense emotions and unpredictable mood swings. There is a strong link between bipolar depression and having a short temper, as people with this disorder can become upset whether they are in a manic or depressive phase. It doesn’t take much to irritate them, and it is almost impossible to anticipate what causes them to lash out. Changes in the weather, having to interact with certain people, or feeling overwhelmed by small things can all trigger sudden changes in mood. Many teens with anger issues also have mood disorders, as unpredictable or uncalled for anger is often a symptom of a much larger issue.

Other Symptoms To Look For

Because bipolar depression can be difficult to diagnose, it’s best to be aware of other symptoms it’s associated with. Bipolar depression often occurs alongside other mental health issues, as many teenagers with ADHD are also diagnosed with bipolar depression. Although bipolar depression will always alternate between manic and depressive episodes, not all teens display the same symptoms or behavior. Here are a few symptoms that can indicate bipolar depression:

  • Stomach issues
  • Physical aches or pain
  • Anxiety 
  • Lack of interest in activities and hobbies
  • Risky behavior
  • Hypersexuality 
  • Extreme irritability or hostile behavior 
  • Extreme focus and productivity 
  • Fatigue
