Most people’s moods move around a bit — a good week, a rough one, a stretch where stress or exhaustion makes everything feel harder. Those shifts usually settle back down within a few days on their own. What I’m evaluating for is something more extreme and more persistent: cycles between an energized, driven “up” and a flat, hopeless “down” that don’t resolve the way an ordinary bad week does.
That pattern is bipolar disorder, formerly known as manic depression. It isn’t a personality trait or a matter of willpower — it’s a mood disorder with a biological basis, and it looks different from one person to the next.
What the cycles look like
Bipolar disorder isn’t a single, uniform illness. It covers a spectrum of presentations, and the changes in mood are usually severe enough to cause real difficulty managing daily life — work, relationships, sleep, judgment. During a manic or hypomanic phase, I often hear about unusual talkativeness, racing thoughts, or a burst of energy and purpose that feels out of character. During the depressive phase, the pattern often reverses into excessive sleep, low energy, and a return of classic depressive symptoms.
The timing of these cycles varies considerably. Some people shift mood states several times a week. Others go months between episodes, and for some the pattern has a seasonal quality to it.
Is it ongoing?
Bipolar disorder is a long-term condition that requires consistent management rather than treatment during episodes alone. Because the frequency and pattern of cycling differs so much from person to person, the treatment plan has to be built around the individual’s actual pattern, not a generic timeline.
What causes it
The exact cause isn’t fully understood. The leading explanations point to imbalances in brain chemistry — particularly the neurotransmitters involved in regulating mood — along with a genetic component. Bipolar disorder does appear to run in families, which is part of why I always ask about psychiatric history on both sides when I’m evaluating a new patient.
How it’s treated
Treatment typically starts with a mood-stabilizing medication, sometimes supplemented with an antidepressant or anti-anxiety medication depending on the specific symptom pattern. Psychotherapy — cognitive behavioral therapy and interpersonal therapy in particular — is a meaningful part of most treatment plans alongside medication. For patients who haven’t responded adequately to antidepressants, transcranial magnetic stimulation is sometimes a useful additional option.
- Avoiding alcohol and recreational drugs, which can trigger or worsen episodes
- Maintaining regular exercise
- Protecting consistent, adequate sleep
- Practicing stress-reduction techniques such as yoga or meditation
A bipolar diagnosis can feel overwhelming at first, especially after an episode that’s disrupted work or relationships. With consistent treatment, though, it’s a highly manageable condition, and most of the patients I treat for it go on to build stable, fulfilling lives around it.
