mental illness …. or too much caffeine?

Article at  La Trobe University website on a report from a study looking into connections between caffeine consumption and “symptoms of schizophrenia” .

so, it’s a “caffeine imbalance” ?

Guess what? the more caffeine we consume the more likely we are to experience “symptoms of schizophrenia” d’oh!

Five cups a day was found to be enough to reliably have folks hearing Bing Crosby singing “White Christmas” with no other “external stimulus” than being locked in a room alone [mind you, that’ll do it by itself].

The study concludes with, likey, what you already know but might prefer to ignore..

  • high caffeine levels and stressful life events lead to higher levels of ‘hallucination’ 
  • everyone, to some degree, can experience “symptoms of schizophrenia”.


caffeine consumption as proxy for sleeplessness

Here’s a chart by Professor Matt Walker ilustrating sleeplessness in the modern world by plotting data from The Financial Times, a proxy for caffeine consumption -the increase over two decades in the number of coffee houses of just one popular chain…

But, before you blame it all on the bean don’t forget the world’s most psychotropic chemical caffeine now pops up everywhere including tea and many of the drinks you give to your kids.

Caffeine the hallucinogen?

 03 Jun 2011

Caffeine is the most commonly used psychoactive drug. Coffee and other caffeinated beverages such as tea, soft-drinks and energy drinks access the stimulant and when taken in large quantities increase tendencies to hallucinate says La Trobe University’s Professor Simon Crowe, School of Psychological Sciences.

In a recent study— The effect of caffeine and stress on auditory hallucinations in a non-clinical sample —Professor Crowe and colleagues measured the effect of stress and caffeine with 92 non-clinical participants. Five coffees a day or more was found to be enough to increase the participant’s tendency to hallucinate says Professor Crowe. ‘High caffeine levels in association with high levels of stressful life events interacted to produce higher levels of ‘hallucination’ in non-clinical participants, indication that further caution needs to be exercised with the use of this overtly “safe” drug,’ he says. The participants were assigned to either a high or a low stress condition and a high or a low caffeine condition on the basis of self-report. The participants were then asked to listen to white noise and to report each time they heard Bing Crosby’s rendition of “White Christmas” during the white noise. The song was never played. The results indicated that the interaction of stress and caffeine had a significant effect on the reported frequency of hearing “White Christmas”. The participants with high levels of stress or consumed high levels of caffeine were more likely to hear the song. ‘There is a link between high levels of stress and psychosis, and caffeine was found to correlate with hallucination proneness. The combination of caffeine and stress affect the likelihood of an individual experiencing a psychosis-like symptom,’ says Professor Crowe. This study also helped to explain the mechanism by which stress may facilitate the symptoms of schizophrenia in non-clinical samples. Caffeine has only recently been reported to increase proneness to hallucinate. ‘The results also support both the diathesis-stress model and the continuum theory of schizophrenia in that stress plays a role in the symptoms of schizophrenia and that everyone, to some degree, can experience these symptoms. This was demonstrated by a significant effect of stress on the occurrence of hallucinatory experiences, or hearing the song,’ says Professor Crowe. ‘It is apparent that the health risks of excessive caffeine use must be addressed and caution should be raised with regards to the exacerbating use of this stimulant,’ he says.
