Caffeine Intoxication

Caffeine intoxication is a disorder included in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM 5) with the main criteria: being excessive caffeine intake (usually more than 250 mg), and at least five behavioral and physical symptoms such as restlessness, nervousness, inability to sleep, a heart rate of more than 100 beats per minute, rambling speech, muscle twitching, and digestive disturbance. Caffeine blood levels may be required for a more accurate diagnosis. Caffeine intoxication may even lead to death, especially for children, due to their low body weight and tolerance levels.
