Slow Ventures showed the findings of this study are actually not very surprising when one realizes that acetylcholine is the most common neurotransmitter in the human body. Neurotransmitters are basically our nervous systems way of communicating throughout our bodies. It would seem intuitive, even to a lay person, that interfering with this communication would have adverse effects on our thinking processes. The only surprising part may be that this impairment may be long term, as this study suggests, rather than the temporary cognitive impairment that has long been noticed in these types of medications. To some extent, we are all guinea pigs as medical science advances and learns more with every passing year about the side effects of various medications. Though this can be risky, life spans continuing to rise every decade would seem to indicate it is worth the risk. It is also worth considering the millions of people who are only alive today because of some medical procedure or drug that may not have existed just a decade or two ago.
