Symptoms & Signs of Bipolar DisorderBipolar disorder is a debilitating, life-altering mental health disorder. Each year, its symptoms will affect nearly six million American adults, which represents about 2.6 percent of the U.S. adult population.1

But this number is deceptive, because trends show that bipolar disorder is becoming more prevalent. According to statistics compiled by the National Institute of Mental Health (NIMH), the lifetime incidence of bipolar disorder for Americans between the ages of 18 and 29 is 5.9 percent, and that is easily the highest rate of incidence for any age-related demographic group.2

Definition of Bipolar Disorder

People dealing with bipolar disorder face significant emotional and psychological disruptions and discontinuities. Bipolar disorder causes sharp mood swings between depression and mania, the latter defined as an excessive and uncontrollable euphoria.

Mental health experts have identified five types of bipolar disorder:

  1. Bipolar Disorder I is the most severe form of the disorder and features alternating periods of intense depression and mania. Hospitalization for emergency treatment is not uncommon among bipolar I sufferers.
  2. Bipolar Disorder II is associated with strong symptoms of depression, but the mania manifests in a milder form called hypomania. The symptoms of hypomania are similar to conventional manic symptoms, but they are far less disruptive and disabling.
  3. Bipolar Disorder, Not Otherwise Specified. Symptoms of depression and mania are experienced in varying patterns and intensity levels. Those who suffer from non-specified bipolar disorder sometimes experience mixed episodes, where symptoms of depression and mania appear simultaneously.
  4. Rapid Cycling Bipolar Disorder. This bipolar type is associated with depressive and manic states that come and go more quickly than usual. A person who experiences two complete cycles of depression and mania in one 12-month period would meet the criteria for rapid cycling bipolar disorder.
  5. Cyclothymic Disorder. Unlike other forms of bipolar, cyclothymic disorder produces episodes of mild depression and hypomania, in the classical alternating cycle.

Bipolar sufferers may experience periods of normalcy, when their emotional equilibrium returns for days, weeks or even months. But without treatment, these respites will only be temporary, and eventually the symptoms of bipolar disorder (either depression or mania) will return in full force.

Bipolar Depression Symptoms

Most people who suffer from bipolar disorder experience depressive states more often than manic states. When depression does develop it tends to last longer than mania (by a margin of 6-12 months versus 3-6 months in bipolar I, where the symptoms of each are experienced more acutely).3 For the most part bipolar depression is indistinguishable from clinical depression, except for its temporary and cyclical nature.

The distinguishing symptoms of bipolar depression include:

  • Low energy, lethargy, fatigue
  • A chronic and omnipresent lack of motivation
  • Feelings of emptiness, a lack of purpose or sense of meaning
  • Loss of interest in favorite hobbies or pastimes
  • Social isolation, withdrawal from family and friends
  • Muted emotional responses
  • Pessimistic, defeatist attitudes
  • Changes in appetite and/or poor nutritional habits
  • Insomnia or changes in sleeping patterns
  • Poor focus and concentration
  • Difficulties in learning or remembering
  • Suicidal threats or actions

Bipolar depression is usually more disabling than bipolar mania, and most people who seek treatment for the symptoms of bipolar disorder do so while in the grips of a depressive state. This can lead to a misdiagnosis of major depression in people who either don’t report their past manic symptoms or have not yet experienced a manic state.

Bipolar Mania Symptoms

Bipolar mania and hypomania generally don’t last as long as bipolar depression, and their symptoms are not as painful and unpleasant. But manic states can be exhausting and unrelenting, wearing sufferers out and leaving them desperate to escape.

The most common symptoms of bipolar mania include:

  • Feelings of runaway euphoria and excitement
  • Agitation, inability to sit or slow down
  • Irritability, sometimes accompanied by explosive fits of anger
  • Jitteriness, nervousness
  • Rapid thoughts and speech
  • Disconnected speech, often jumping quickly between topics
  • Loss of ability to focus or concentrate
  • Insomnia or reduced need for sleep
  • Paranoia, suspiciousness
  • Aggressiveness, hostility
  • Supreme self-confidence, boastfulness
  • Poor impulse control
  • Risky, dangerous behavior
  • Psychosis (delusions, hallucinations)

Bipolar psychosis is an especially worrying condition, and one of the primary reasons why people experiencing manic symptoms end up being hospitalized. Hypomania is not as uncomfortable and disruptive as mania, but at times its symptoms may escalate beyond expectations.

Bipolar Disorder in Youth

Bipolar disorder is primarily an adult condition (the median age of onset is 25), but adolescents and children do experience bipolar symptoms as well.

Studies show that about one percent of teens between the ages of 14 and 18 suffer from bipolar disorder each year.4 Oftentimes those who do are misdiagnosed with depression: estimates are that up to one-third of young people diagnosed with depression are actually suffering from the early symptoms of bipolar depression.5

In children, bipolar disorder is not overly common, and when it does manifest it is often misdiagnosed as ADHD. This can be a problem, since drugs given to kids for ADHD symptoms can trigger troubling outbreaks of intense manic symptoms.

While children are not frequently diagnosed with bipolar disorder, kids whose parents suffer from it should be closely monitored, since bipolar disorder does run in families.

Getting Treatment for Bipolar Disorder

Once an accurate diagnosis has been made, bipolar disorder is highly treatable and the chances of recovery for patients committed to healing is excellent. Unfortunately, many people turn to drugs and alcohol to self-medicate when their mental health disorders go undiagnosed, which explains why approximately 50-60 percent of men and women experiencing the symptoms of bipolar disorder will also struggle with substance use disorders.6
