HMN 2025: How Regular opioid use might improve dementia threat

In a review published in Alzheimer’s & Dementia, a workforce led by Dr. Sha Feng from the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences—collaborating with Dr. Jed A. Barash from the Massachusetts Veterans Home at Chelsea and Prof. W. Andrew Kofke from the University of Pennsylvania—has discovered that common opioid use is related to an elevated threat of dementia, significantly vascular dementia.

Chronic non-cancer ache (CNCP) is outlined as any painful situation that persists for greater than three months and is unrelated to malignancy. Opioid use for CNCP turned widespread within the mid-Nineteen Nineties. Inappropriate prescribing, dependence, and misuse of high-potency opioids have raised public well being issues.

Previous research have advised that opioid use might have an effect on the endogenous opioid system and doubtlessly impair the hippocampus and different central nervous system areas, growing the chance of cognitive decline and dementia.

In this study, the researchers performed a potential cohort study involving 197,673 people with CNCP aged 37 to 73 from the UK Biobank, with a imply follow-up of 13.8 years. They utilized a number of Cox, linear, and logistic regression models, which management for potential confounding elements, to discover the associations between common opioid use and incident dementia, neuroimaging outcomes, and cognitive measures.

The researchers discovered that common opioid use was related to a 20% greater threat of all-cause dementia in contrast with taking analgesics. Participants who commonly used sturdy opioids had an over 70% elevated threat of dementia, and people taking non-opioid analgesics confirmed a threat degree just like the non-users. Besides, a major affiliation between opioid use and vascular dementia (VD) was noticed.

Through neuroimaging analyses, the researchers discovered that common use of sturdy opioids was linked to diminished whole mind quantity (TBV), white matter quantity (WMV), and hippocampal quantity (HV). They additionally discovered that opioid use was related to decrease fluid intelligence, however not considerably related to potential reminiscence decline.

This study underscores the significance of contemplating each opioid efficiency and cumulative publicity when evaluating the associations between opioid use and the chance of dementia or different opposed outcomes. This study offers precious insights into the methods for addressing the advanced interaction between persistent ache, analgesic use, and cognitive impairment.
