Hey guys,
It’s my first post and I would like to share insight’s I have noticed and read. Basically it is that caffeine is a pro-psychotic! It worsens sz symptoms especially when taken in high doses.
I noticed this myself when drinking coffee and suddenly having something like a mind fog and when I drank coffee in even higher doses (really to give me energy) I noticed I felt sort of like inner paralysis. All this being the exact opposite of what I would hope a cup of coffee would do for me.
This is just something I think coffee drinkers should test and see if they notice anything.
There are numerous papers cited but in particular (Lucas et al., 1990) “Effects of the acute administration of caffeine in patients with schizophrenia”.

Abstract: Caffeine, 10 mg/kg, was administered to 13 schizophrenic patients in a double-blind placebo-controlled study of its behavioral effects. Some measures of psychopathology were significantly increased: Brief Psychiatric Rating Scale (BPRS) total, BPRS subscales thought disorder, unusual thought content, and euphiria-activation, and several individual BPRS items. Nurses’ Bunney-Hamberg ratings of psychosis and mania, comparing the day before with the day after pharmacological challenge, increased significantly. Compared to placebo, caffeine also produced significant increases of diastolic blood pressure and cortisol. Thus, these findings indicate that caffeine increases arousal and has a psychotogenic effect when administered to schizophrenic patients. The possible roles of various neurotransmitters is discussed with special emphasis on caffeine’s actions on dopaminergic and adenosinergic systems.
And (Broderick & Benjamin, 2004) “Caffeine and psychiatric symptoms: a review”
http://europepmc.org/abstract/med/15732884
Abstract: Caffeine is a widely used psychoactive substance that has the potential to contribute to many psychiatric symptoms. This review article aims to address the specific research studies and case reports that relate caffeine to psychiatric symptoms. Caffeine can cause anxiety symptoms in normal individuals, especially in vulnerable patients, like those with pre-existing anxiety disorders. Caffeine use is also associated with symptoms of depression due to either a self-medication theory, or a theory that caffeine itself causes changes in mood. Psychosis can be induced in normal individuals ingesting caffeine at toxic doses, and psychotic symptoms can also be worsened in schizophrenic patients using caffeine. Sleep and symptoms of ADHD may be altered by caffeine as well. Prevention of caffeine-induced psychiatric symptoms is possible by recognizing, educating, and treating patients using a tapering approach.
This goes for all adeneosine blockers (the mechanism that is pro-psychotic) including caffeine such as cocoa and tea in large enough amounts.
