In a study of over 200 university students, researchers found that having the equivalent of 8 or more cups of coffee a day resulted in a 3 times higher risk of hallucination, such as hearing voices. While hallucinations are often a symptom of schizophrenia, they can also occur in healthy individuals. From Boston, according to research in Circulation: Cardiovascular Quality and Outcomes, women with cardiac symptoms are more likely to experience delays on the trip to the hospital than men. In a retrospective study of over 5,800 patients, researchers found that women were 52% more likely to be delayed 15 minutes past the median time of 34 minutes in EMS care. The researchers suggest that differences in symptom presentation between men and women may be the cause.
