Caffeine has been found to induce manic symptoms and trigger the onset of BD in people with no history of psychiatric disorders at baseline.
Manic symptoms
Most research on the effects of caffeine on people with bipolar disorder indicates that the stimulant may trigger manic episodes. Caffeine acts as a mood elevator. Some experts have suggested that caffeine may, as a result, trigger the disorder's manic episodes, which some may refer to as high periods.

“Stimulants can trigger mania and should be avoided,” says Jess G. Fiedorowicz, MD, PhD, an associate professor in the departments of psychiatry and internal medicine at the University of Iowa Carver College of Medicine in Iowa City.
Caffeine raises dopamine levels in the brain, which can cause increased anxiety, restlessness, and thus induce mania or hypomania (which can then bring on a loss of appetite when you have bipolar disorder).
One cross-sectional study found that patients with (bipolar or unipolar) depression reported more anxiety in response to caffeine compared to controls with no psychiatric 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.
As a competitive adenosine antagonist, caffeine affects dopamine transmission and has been reported to worsen psychosis in people with schizophrenia and to cause psychosis in otherwise healthy people.
If you have mania, you'll probably need to take medicine to bring it quickly under control. Your doctor will also likely prescribe a mood stabilizer, also called an “antimanic” medication. These help control mood swings and prevent them, and may help to make someone less likely to attempt suicide.
Early signs (called “prodromal symptoms”) that you're getting ready to have a manic episode can last weeks to months. If you're not already receiving treatment, episodes of bipolar-related mania can last between three and six months. With effective treatment, a manic episode usually improves within about three months.
The results showed that manic episodes led to decreased volume in certain areas of the brain. Bipolar disorder has been linked to various structural brain changes, including most notably progressive grey matter loss in the brain's frontal regions.
Evidence from different functional neuroimaging studies suggest that there is a reduced activity of right ventromedial and ventrolateral prefrontal cortices and an increased activity of left amygdala, left anterior cingulate cortex, and left basal ganglia in mania.
Detection of mania, or at least of brief hypomania, is required for diagnosis of bipolar disorder. This diagnosis is often missed or not remembered as an illness. People close to the patient may recall episodes, however, and patients who do not remember episodes of affective disturbance may recall their consequences.
A bipolar depression crash is usually the emotional fallout of a hypomanic or manic episode. It can also occur when something triggers bipolar depression or as a result of chemical or hormonal changes in the brain.
There are three stages of mania: hypomania, acute mania and delirious mania. Classifications of mania are mixed states, hypomania and associated disorders.
Mania and hypomania are symptoms that can occur with bipolar disorder. They can also occur in people who don't have bipolar disorder.
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.
Although bipolar disorder can occur at any age, typically it's diagnosed in the teenage years or early 20s.
While many bipolar disorder triggers center around stressors, goal attainment and other positive events can also elicit mood episodes, particularly mania or hypomania. Events such as winning an award, getting a promotion, falling in love, or even going on vacation may act as triggers, initiating a dangerous cycle.
