Editorial: Insights in Alzheimer's disease and related dementias

According to the World Alzheimer's Report (Alzheimer's Disease International, 2022) and the Global status report on the public health response to dementia (WHO, 2022), 55+ million people live with dementia, a condition characterized by deterioration in cognition and functionality beyond the expected effects of normal aging. WHO has recognized dementia as a public health priority. Alzheimer's disease and related dementias (ADRD) may result from a disparate combination of processes, including genetic and environmental factors (fiscal, social, economic), pathological processes, and injuries that primarily or secondarily affect the brain. Dementia is a leading cause of disability, dependence and death among older people globally. The impact of dementia at personal and societal levels is unequally distributed, usually following a distribution similar to that of the inequality index of the corresponding country.
