A new analysis of seven observational studies involving over 7 million people suggests that systemic lupus erythematosus (SLE) is linked to a higher risk of cognitive impairment. The meta-analysis found that people with lupus had 53% higher odds of cognitive problems compared to those without the condition. The link held across different populations, including both Asian and non-Asian groups, and was seen in both men and women, though the effect appeared stronger in women (98% higher odds).
The study did not look at dementia separately, and because it combined observational studies, it cannot prove that lupus causes cognitive decline. The researchers note that other factors could explain the connection. No information on safety or side effects was reported, as this was not a treatment study.
The findings highlight the importance of monitoring cognitive health in people with lupus. However, the results should be interpreted with caution due to the observational nature of the included studies. For now, the takeaway is that lupus patients may benefit from regular cognitive screening as part of their care.
