"Insights from Ancient Greece: Dementia Eluded the Greeks"
A study of ancient Greek and Roman medical texts suggests that dementia was rare 2,000 to 2,500 years ago, with records focusing on physical frailties of aging rather than symptoms associated with Alzheimer's disease. Symptoms associated with dementia began to surface in Roman times, possibly due to new environmental factors such as increased pollution and exposure to neurotoxins. The study's lead author cross-checked his findings with a population in the Bolivian Amazon, finding minimal dementia rates among those with an active, pre-industrial lifestyle, supporting the theory that sedentary lifestyle and pollution are major factors in cognitive decline.
