Bipolar disorder is a mental illness that causes extreme mood swings including emotional highs called mania or hypomania) and lows called depression.
The mood swings may even become mixed, and when this happens you might feel elated and depressed at the same time. These mood swings can affect sleep, energy, activity, judgment, behavior and the ability to think clearly. Bipolar disorder is a lifelong condition which may occur rarely or multiple times a year. But you can manage your mood swings and other symptoms by following a treatment plan.

Signs and Symptoms of Bipolar Disorder:

Signs and symptoms of bipolar disorder can be divided into those for mania, and those for depression.

Signs of Mania include:

  • feeling overly happy or high for long periods of time
  • talking very fast, often with racing thoughts
  • having overconfidence in your abilities
  • engaging in risky behavior, such as having impulsive sex, gambling with life savings, or going on big spending sprees
  • having a decreased need for sleep
  • feeling extremely restless or impulsive
  • becoming easily distracted

Signs of Depression include:

  • feeling sad or hopeless for long periods of time
  • losing interest in activities that you once enjoyed
  • feeling severe fatigue or lack of energy
  • withdrawing from friends and family
  • having a significant change in appetite
  • having problems with memory, concentration, and decision making
  • thinking about or attempting suicide, or having a preoccupation with death

Both mania and depression can cause other symptoms as well. These could be anxious distress, melancholy, psychosis or others. The timing of symptoms may include diagnostic labels such as mixed or rapid cycling. In addition, bipolar symptoms may occur during pregnancy or change with the seasons. Many of these symptoms can also be caused by other conditions which makes it hard to diagnose the condition.

Symptoms in Children and Teens:

Symptoms of bipolar disorder can be difficult to identify in children and teens. It is hard to recognize the mood swings whether these are normal ups and downs or the results of stress or trauma, or signs of a mental health problem other than bipolar disorder.
The pattern of major depressive or manic or hypomanic episodes can vary from that of adults with bipolar disorder. The moods can rapidly shift during episodes. Some children may have periods without mood symptoms between episodes. Severe mood swings that are different from their usual mood swings could be a prominent signs of bipolar disorder in children and teenagers.

Bipolar Disorder Types and Symptoms:

There are four common types of bipolar disorder.

Bipolar I:

This is also known as manic depression where the behavior and moods of the person are extreme and their behavior quickly escalates until they are out of control. 
A person must have at least one manic episode that may be preceded or followed by hypomanic or major depressive episodes to have bipolar I.
An episode can be considered a manic episode, if it:

  • include moods or behaviors that are different from the usual behavior of a person
  • so extreme that the person needs immediate hospital care

Usually people with bipolar I, will have depressive episodes as well, but a depressive episode is not required to make the bipolar I diagnosis.

Bipolar II:

These are more common than bipolar I. You will have at least one major depressive episode and at least one hypomanic episode, but you will never experience a manic episode.
Hypomania often becomes worse without treatment, and the person can become severely manic or depressed.

Cyclothymic disorder:

These are less common than bipolar I and II. But involves mood swings and shifts similar to bipolar I and II which are often less dramatic in nature. A person with cyclothymic disorder can often function normally without medication, though it may be hard. Over time, mood swings of a person may develop into a diagnosis of bipolar I or II.

Other types:

These include, bipolar and related disorders induced by certain drugs or alcohol or due to a medical condition, such as Cushing disease, multiple sclerosis or stroke.
Although bipolar disorder can occur at any age, usually it is diagnosed in the teenage years or early 20s. Symptoms can vary from person to person, and over time it can get serious.
