Research from the University of Southern California suggests that severe memory loss, prevalent in today's society, was exceptionally rare 2,000 to 2,500 years ago during the time of Aristotle, Galen, and Pliny the Elder. The study, titled "Dementia in the Ancient Greco-Roman World Was Minimally Mentioned," draws on an analysis of classical Greek and Roman medical texts, revealing minimal references to advanced cognitive decline.
Unlike contemporary concerns about Alzheimer's disease (AD), which affects a significant portion of the aging population, ancient Greeks recognized mild cognitive impairment associated with aging but did not document major memory loss, speech issues, or reasoning problems characteristic of modern dementia. The researchers, including gerontologist Prof. Caleb Finch and historian Stanley Burstein, delved into the works of Hippocrates and his followers, finding mentions of ailments common in the elderly but an absence of references to memory loss.
As the study progressed to ancient Rome, a few instances of memory-related challenges emerged. Galen noted that by the age of 80, some individuals faced difficulties in learning new things, while Pliny the Elder recounted an incident where a senator forgot his own name. Cicero observed a form of "elderly silliness" among some older individuals. Finch speculates that as Roman cities grew denser, environmental factors such as pollution and lead exposure might have contributed to cognitive decline.
The researchers also considered the impact of lifestyle on dementia risk. Drawing parallels with the preindustrial lifestyle of the Tsimane Amerindians in the Bolivian Amazon, known for their physical activity and low dementia rates, they emphasized the influence of environmental factors. The Tsimane data serves as a valuable model, indicating that an active lifestyle may play a crucial role in minimizing dementia risk.
In conclusion, this research challenges the notion that Alzheimer's and related dementias have always been prevalent across human history. Instead, it suggests that environmental and lifestyle factors, such as sedentary behavior and exposure to pollution, may be key contributors to the modern epidemic of severe memory loss.
