Understanding bipolar disorder
The word âbipolarâ means âtwo extremesâ. For the many millions experiencing bipolar disorder around the world, life is split between two different realities: elation and depression. Although there are many variations of bipolar disorder, letâs consider a couple. Type I has extreme highs alongside the lows, while Type II involves briefer, less extreme periods of elation interspersed with long periods of depression. For someone seesawing between emotional states, it can feel impossible to find the balance necessary to lead a healthy life.

Type I has extreme highs alongside the lows, while Type II involves briefer, less extreme periods of elation interspersed with long periods of depression. For someone seesawing between emotional states, it can feel impossible to find the balance necessary to lead a healthy life.
Type Iâs extreme highs are known as manic episodes, and they can make a person range from feeling irritable to invincible. But these euphoric episodes exceed ordinary feelings of joy, causing troubling symptoms like racing thoughts, sleeplessness, rapid speech, impulsive actions, and risky behaviors. Without treatment, these episodes become more frequent, intense, and take longer to subside.
The depressed phase of bipolar disorder manifests in many ways: a low mood, dwindling interest in hobbies, changes in appetite, feeling worthless or excessively guilty, sleeping either too much or too little, restlessness or slowness, or persistent thoughts of suicide.
Worldwide, about 1-3 percent of adults experience the broad range of symptoms that indicate bipolar disorder. Most of those people are functional, contributing members of society, and their lives, choices, and relationships arenât defined by the disorder. But still, for many, the consequences are serious. The illness can undermine educational and professional performance, relationships, financial security, and personal safety.
So what causes bipolar disorder? Researchers think a key player is the brainâs intricate wiring. Healthy brains maintain strong connections between neurons, thanks to the brainâs continuous efforts to prune itself and remove unused or faulty neural connections. This process is important because our neural pathways serve as a map for everything we do.Â
Using functional magnetic resonance imaging, scientists have discovered that the brainâs pruning ability is disrupted in people with bipolar disorder. That means their neurons go haywire and create a network thatâs impossible to navigate. With only confusing signals as a guide, people with bipolar disorder develop abnormal thoughts and behaviors.
Also, psychotic symptoms, like disorganized speech and behavior, delusional thoughts, paranoia, and hallucinations, can emerge during extreme phases of bipolar disorder. Â This is attributed to the overabundance of a neurotransmitter called dopamine. Â Â
But despite these insights, we canât pin bipolar disorder down to a single cause: in reality itâs a complex problem. For example, the brainâs amygdala is involved in thinking, long-term memory, and emotional processing. In this brain region, factors as varied as genetics and social trauma may create abnormalities and trigger the symptoms of bipolar disorder. The condition tends to run in families, so we do know that genetics have a lot to do with it. But that doesnât mean thereâs a single âbipolar gene.â In fact, the likelihood of developing bipolar disorder is driven by the interactions between many genes, in a complicated recipe weâre still trying to understand.
The causes are complex, and consequently, diagnosing and living with bipolar disorder is a challenge. Despite this, the disorder is controllable by way of many methods including mood stabilizing medications, therapy, and behavioral habit-forming like exercise, sleep, and sobriety.
Remember, bipolar disorder is a medical condition, not a personâs fault, or their whole identity. And itâs something that can be controlled through a combination of medical treatments doing their work internally; friends and family fostering acceptance and understanding on the outside; and people with bipolar disorder empowering themselves to find balance in their lives.

This month is Mental Health Awareness month. In educating yourself about mental illness, you can be a more empathetic and supportive friend, partner, or family member to someone suffering with depressing or another mental illness.Â
