Lastly, lean may also contain a combination of alcohol, caffeine, and/or sugar. Caffeine antagonises the brain’s A1 and A2 adenosine receptors, explaining its effects on the body’s motor activity, such as boosting exercising activity or increasing physical agitation. When looking at leans side effects, its important to keep in mind that. Drinking coffee and other caffeinated products has significant effects on the brain and body because caffeine interacts with the dopamine system. Fortunately, these symptoms are usually mild and get better after a few days. Caffeine is highly addictive because it activates reward-orientated mechanisms within the brain, giving people unpleasant withdrawal symptoms such as headaches or brain “fog” when they stop or reduce it. An abrupt decrease in caffeine may cause withdrawal symptoms, such as headaches, fatigue, irritability and difficulty focusing on tasks. The psychoactive effects of caffeine are similar to some of the effects of stimulant drugs such as amphetamines or cocaine.
Further longitudinal research is needed to explore whether people who consume a high amount of caffeine are at greater risk of psychosis.Ĭaffeine is clinically classed as a drug because it has significant effects on the brain and body. The patient was also experiencing delusions of reference (a type of delusion involving thinking that trivial or innocuous things have great personal significance or meaning) by being preoccupied with the number 33. The patient sought help because of hallucinations that involved seeing things that were not there and having paranoia about being followed. Another clinical case study reported a patient who had been drinking several cups of coffee and energy drinks each day. The patient’s psychotic symptoms subsided naturally after reducing caffeine consumption for 7 weeks without taking any anti-psychotic medicine. One study described a patient who started suffering from paranoia and delusions after consuming a large amount of caffeine. Treatment Prevention Caffeine overdose is very rare, but it is often related to energy drinks or caffeine supplements that can contain very high levels of this stimulant. Clinical case studies suggest that caffeine can induce psychosis in otherwise healthy people.
