Although bipolar disorder can occur at any age, typically it's diagnosed in the teenage years or early 20s.
Bipolar disorder (BD) is a chronic mental disorder characterized by alternating episodes of depression, euthymia, (hypo) mania, and mixed states. [1] The usual age of onset of BD is before 30 years, and almost 90% of patients have onset before 50 years of age.
You usually develop bipolar disorder before you are 20. It can develop in later life, but it rarely develops after the age of 40. You could have symptoms of bipolar disorder for some time before a doctor diagnoses you.
Bipolar disorder is frequently inherited, with genetic factors accounting for approximately 80% of the cause of the condition. Bipolar disorder is the most likely psychiatric disorder to be passed down from family. If one parent has bipolar disorder, there's a 10% chance that their child will develop the illness.
A stressful circumstance or situation often triggers the symptoms of bipolar disorder. Examples of stressful triggers include: the breakdown of a relationship. physical, sexual or emotional abuse. the death of a close family member or loved one.
No one knows exactly what causes bipolar disorder. Research suggests that a combination of factors could increase your chance of developing it. This includes physical, environmental and social conditions.
Bipolar Triggers and Warning Signs
Bipolar disorder features extreme shifts in mood that are unpredictable and often disruptive to daily functioning. Changes in sleep patterns, eating habits, emotions, and behaviors accompany the mood swings.
To diagnose bipolar disorder, a doctor performs a physical exam, asks about your symptoms, and recommends blood testing to determine if another condition, such as hypothyroidism, is causing your symptoms. If the doctor does not find an underlying cause of your symptoms, he or she performs a psychological evaluation.
Although symptoms may come and go, bipolar disorder usually requires lifelong treatment and does not go away on its own. Bipolar disorder can be an important factor in suicide, job loss, ability to function, and family discord. However, proper treatment can lead to better functioning and improved quality of life.
Bipolar disorder is easily confused with depression because it can include depressive episodes. The main difference between the two is that depression is unipolar, meaning that there is no “up” period, but bipolar disorder includes symptoms of mania.
Most studies, but not all, report an almost equal gender ratio in the prevalence of bipolar disorder but the majority of studies do report an increased risk in women of bipolar II/hypomania, rapid cycling and mixed episodes. Important gender distinctions are also found in patterns of co-morbidity.
Bipolar disorder affects men and women equally, as well as all races, ethnic groups, and socioeconomic classes. Although men and women appear to be equally affected by bipolar disorder, rapid cycling is seen more often in women. Women also tend to experience more depressive and mixed state episodes than do men.
The main sign of bipolar disorder is extreme mood swings that go from emotional highs to emotional lows. Manic episodes cause people to seem very energetic, euphoric, or irritable. During depressive episodes, your loved one may seem sad, upset, or tired all the time.
Cyclothymia symptoms alternate between emotional highs and lows. The highs of cyclothymia include symptoms of an elevated mood (hypomanic symptoms). The lows consist of mild or moderate depressive symptoms. Cyclothymia symptoms are similar to those of bipolar I or II disorder, but they're less severe.
A blood test therefore could help identify those with bipolar disorder experiencing depressive episodes. A 2021 study of a new assay test showed it's possible to diagnose low blood mBDNF levels in people with MDD or bipolar disorder within an accuracy rate of 80 to 83 percent.
There are no specific blood tests or brain scans to diagnose bipolar disorder. Even so, a doctor may perform a physical exam and order lab tests, including a thyroid function test and urine analyses. These tests can help determine if other conditions or factors could be causing your symptoms.
Lamotrigine. Lamotrigine (Lamictal) may be the most effective mood stabilizer for depression in bipolar disorder, but is not as helpful for mania. The starting dose of lamotrigine should be very low and increased very slowly over four weeks or more.
Bipolar episodes will swing from extreme highs (manic episodes) to very low depressive states. When either of these episodes are coupled with rage, it can be devastating. “People diagnosed with bipolar disorder can experience anger during a manic or depressive episode. There is no distinction between the two.”
People with bipolar experience both episodes of severe depression and episodes of mania – overwhelming joy, excitement or happiness, huge energy, a reduced need for sleep, and reduced inhibitions. The experience of bipolar is uniquely personal. No two people have exactly the same experience.
Unfortunately, there's no known way to prevent bipolar disorder because scientists don't know its exact cause. But it's important to know the signs and symptoms of bipolar disorder and to seek early intervention.
A 2009 study on the long-term effects of bipolar disorder showed that it can cause structural changes to the brain, especially in some lower parts of the frontal lobe. These changes were visible in older participants after an MRI — an imaging test that shows tissues and other structures on the inside of your body.
