Mounjaro and dementia: what the new study says
GLP-1 weight loss drugs, like Wegovy (Ozempic), Saxenda and Mounjaro, have already been linked to benefits beyond weight loss from reducing cancer risk to lowering heart disease.
Now, a major new study published in the journal Naunyn-Schmiedeberg’s Archives of Pharmacology has found that these drugs may also help protect against dementia.
Researchers analysed health records from over 1.5 million patients with type 2 diabetes or obesity, comparing those who took GLP-1 medications with those who did not.
The headline result?
People using GLP-1 drugs had a 46% lower risk of developing dementia compared to those on other treatments. Read the full study here.
Why it matters for SlimrChat users
For our community, this isn’t just a medical curiosity, it’s a reminder of how powerful these weight loss jabs can be in shaping long-term health.
We already know that carrying excess weight increases the risk of heart disease, stroke, and cancer. But dementia has been a quieter, equally serious concern. Studies now suggest that by helping control inflammation, blood sugar, and insulin resistance, GLP-1 drugs could help slow the processes that lead to cognitive decline.

Don’t forget the bigger picture
While these findings are exciting, they don’t mean weight loss drugs are a guaranteed shield against dementia. Lifestyle still matters: exercise, sleep, diet, and mental stimulation all play a part in protecting brain health.
But for those using or considering Mounjaro, it’s another reason to feel confident about your decision. You’re not just aiming for a healthier weight — you could be protecting your future in more ways than one.
