Cyclothymia: The "Quiet Bipolar" Nobody Notices

Cyclothymia is not simply a "moody personality." It involves genuine, recurring swings between highs and lows — but the swings never reach the intensity that would make others call for help or urge a visit to the doctor. That is precisely what sets cyclothymia apart from full-spectrum bipolar disorder.

How cyclothymia differs from bipolar disorder

In a true manic episode, the change in a person's mood and behaviour is impossible to miss — for the individual and for everyone around them. Cyclothymia works differently: the swings are real and regular, but they stay "in the shadows." Dr. Saulitis puts it plainly: if the episodes go unnoticed by the people around you, what you are dealing with is cyclothymia, not a full bipolar presentation.

Who is especially vulnerable

People living at northern latitudes are at particular risk. Seasonal changes in light and day length are directly tied to mood rhythms, and for those in the north, cyclothymic fluctuations come, in the doctor's words, "by definition" — a background feature shaped by climate itself.

How to recognise it in yourself

The key marker is regularity: mood "jumps" without any clear external trigger. One day everything feels wonderful; the next brings sadness and low energy. This is not a normal reaction to life events — it is an internal cycle. The first step is to honestly observe whether your mood shifts follow a pattern that has nothing to do with specific circumstances.

What to do first

Before seeing a specialist, Dr. Saulitis suggests starting with the basics: cut out sugar, add B-group vitamins, regulate sleep, and take regular walks. In his view, this alone should produce roughly 80% improvement. If mood swings persist after these changes, it makes sense to consult a psychiatrist. Before that visit, getting an EEG is worthwhile — it provides important additional information.
