Description

Sara Javidnia and thirteen co-authors test whether opioid use disorder raises the risk of dementia. Their records study covered about 222,500 veterans of European and African ancestry in the Million Veteran Program. A genetic method added data from genome studies of over six million people, and a small imaging group contributed brain scans tracked over time. The disorder came with a clearly higher rate of dementia overall, plus higher rates of Alzheimer's disease and vascular dementia.

The genetic analysis backed a possible causal link, with inherited liability to the disorder tied to higher dementia odds. Variation in the gene for the main opioid receptor also tracked with dementia risk. Brain structure, though, showed no link with genetic risk scores. The authors read the pattern as evidence that opioid pathways may feed into brain degeneration.
