Four types of 'common' medication may cause dementia expert says

  • A recent study published April 30 in Neurology analyzed UK Biobank data from nearly 281,000 participants averaging 57 years old to examine dementia risk.
  • Researchers investigated how advanced biological age, influenced by lifestyle, relates to dementia development and found a 30% increased risk compared to normal aging.
  • Participants with higher biological age showed brain changes, including grey matter shrinkage linked to dementia, based on MRI scans and a 14-year follow-up during which nearly 4,800 developed dementia.
  • Lead researcher Yacong Bo highlighted that alterations in brain anatomy account for part—but not the entirety—of the link between accelerated biological aging and dementia, underscoring how lifestyle choices can influence biological age.
  • The study indicates a potential link between accelerated biological aging and an increased risk of developing dementia, though it does not establish a direct cause-and-effect relationship, underscoring the importance of lifestyle choices in managing dementia risk.
