However, caffeine does not induce a release of dopamine in the nucleus accumbens but leads to a release of dopamine in the prefrontal cortex, which is consistent with caffeine reinforcing properties. In classical drugs of abuse, such as amphetamines and cocaine, adenosine stimulates dopaminergic activity in the nucleus accumbens, thus producing dopamine-like effects in that part of the brain, which accounts for its addictive potential. Individuals who regularly consume caffeine have increased the number of adenosine receptors in their central nervous system (CNS) and become more sensitive to the normal physiologic effects of adenosine. PathophysiologyĬaffeine is a competitive adenosine receptor antagonist, thus blocking endogenous adenosine, thus preventing the onset of drowsiness, caused by adenosine. There is a wide variation in the caffeine content of beverages. A total intake of no more than 400 mg per day is the accepted safe level this would typically be four cups of coffee, ten cans of cola, or two energy drinks. So-called energy drinks are also gaining popularity in recent years. The major sources of caffeine in the US are coffee, tea, and soft drinks. The mean daily intake in the United States (US) is 280 mg, which is equal to about one or two mugs of coffee or three to five soft drinks. It has been reported that in North America, 80% to 90% of all adults use caffeine regularly. The true incidence of caffeine withdrawal syndrome is unknown. Some of the rich sources of caffeine intake are coffee, tea, green tea, yerba mate, energy drinks, caffeinated soda (cola-type), and chocolates (mostly dark). The research studies have validated that avoidance of withdrawal symptoms plays a vital role in habitual caffeine consumption in addition to the dread of pure physiologic withdrawal symptoms.
Regular and chronic use of caffeine produces physical and psychological dependence. Etiologyīeverages containing caffeine are ingested to prevent or relieve drowsiness, stimulate the central nervous system, and improve performance. They also can be the cause of abnormal vital signs, such as tachycardia, increased respiratory rate, and low or elevated blood pressure, and as such, can present a diagnostic challenge and/or be a cause of unnecessary workup in ED. Physicians working in the emergency departments (ED) and the hospital must be familiar with this syndrome when they encounter patients with relevant symptoms, as they overlap with symptoms such as anxiety, depression, mood disorders, insomnia.

Multiple studies have demonstrated that caffeine-withdrawal syndrome is a clinically relevant entity and is included in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. Individuals who habitually drink caffeine-contained beverages may develop a physical, emotional, and psychological dependence on it and may experience a caffeine withdrawal syndrome after abrupt cessation of caffeine intake. Unlike other psychoactive drugs, it is legal, cheap, and not regulated in almost all parts of the world.

Describe the pathophysiology of caffeine withdrawal.This activity reviews the pathophysiology, presentation, and diagnosis of caffeine withdrawal and stresses the importance of the interprofessional team in its management. As a result, individuals who habitually drink caffeine-contained beverages may develop a physical, emotional, and psychological dependence on it and may experience a caffeine withdrawal syndrome after abrupt cessation of caffeine intake. Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class and is one of the most widely used drugs in the world.
