In most people with bipolar disorder, there is no clear cause for the periods (episodes) of extreme happiness (mania) or depression. The following may trigger a manic episode:
- Medicines such as antidepressants or steroids
- Periods of not being able to sleep (insomnia)
- Recreational drug use
The manic phase may last from days to months. It can include these symptoms:
- Easily distracted
- Little need for sleep
- Poor judgment
- Poor temper control
- Reckless behavior and lack of self control such as drinking, drug use, sex with many partners, spending sprees
- Very elevated, expansive or irritable mood, such as racing thoughts, talking a lot, false beliefs about self or abilities
- Very involved in activities
The depressive episode may include these symptoms:
- Daily low mood or sadness
- Difficulty concentrating, remembering, or making decisions
- Eating problems such as loss of appetite and weight loss, or overeating and weight gain
- Fatigue or lack of energy
- Feeling worthless, hopeless, or guilty
- Loss of pleasure in activities once enjoyed
- Loss of self-esteem
- Thoughts of death or suicide
- Trouble getting to sleep or sleeping too much
- Pulling away from friends or activities that were once enjoyed
Episodes of depression are more common than episodes of mania. The pattern is not the same in all persons with bipolar disorder:
- Depression and mania symptoms may occur together. This is called a mixed state.
- Symptoms may also occur right after each other. This is called rapid cycling.
Signs and tests
To diagnose bipolar disorder, the health care provider may do some or all of the following:
- Ask whether other family members have bipolar disorder.
- Ask about your recent mood swings and for how long you have had them.
- Perform a thorough exam and order lab tests to look for other illnesses that may be causing the symptoms that resemble bipolar disorder.
- Talk to family members about your symptoms and overall health.
- Ask about any health problems you have and any medications you take.
- Watch your behavior and mood.
The main goal of treatment is to:
- Make the mood episodes less frequent and severe
- Help you function well and enjoy your life at home and at work
- Prevent self-injury and suicide
Medicines are a key part of treating bipolar disorder. Most often, the first medicines used are called mood stabilizers They help you avoid mood swings.
With medicines, you may begin to feel better. For some, symptoms of mania may feel good. Or side effects from the medicines may occur. As a result, you may be tempted to stop taking your medicine or change the way you are taking them. But stopping your medicines or taking them in the wrong way can cause symptoms to come back or become much worse.
Family members or friends can help you take medicines the correct way. They can also help to make sure that episodes of mania and depression are treated as early as possible.
Other medicines, such as antipsychotics or antidepressants, may be tried.
Regular visits with a psychiatrist to talk about your medicines and side effects are needed. Blood tests are often needed also.
Electroconvulsive therapy (ECT) may be used to treat the manic or depressive phase if it does not respond to medication.
Patients who are in the middle of a severe manic or depressive episode may need to stay in a hospital until their mood is stable and their behavior is under control.
SUPPORT PROGRAMS AND TALK THERAPYMany people with bipolar disorder do not recognize when they are becoming more depressed or more manic. Joining a support group may help you and your loved ones. Involving family members and caregivers in your treatment programs may help reduce the chance of symptoms returning in the patient.
Important skills that may be learned at such programs include:
- Coping with symptoms that are present even while taking medications
- Getting enough sleep and staying away from recreational drugs
- Taking medicines correctly and how to manage side effects
- Watching for the return of symptoms, and knowing what to do when they return
- Finding out what triggers the mood episodes and how to avoid these triggers
Talk therapy with a mental health provider may be helpful for people with bipolar disorder.
Periods of depression or mania return in most patients, even with treatment. Patients may also have issues with alcohol or drug abuse. They may also have problems with relationships, school, work, and finances.
Suicide is a very real risk during both mania and depression. People with bipolar disorder who think or talk about suicide need emergency attention right away.
