Amongst 3224 alive and non-demented participants whose follow-up extended beyond the next examination round (after on average 5.9 years), higher cerebral perfusion at baseline was associated with less decline in global cognition (p=0.02). Conclusion: Cerebral hypoperfusion is associated with an increased risk of cognitive decline and dementia in the general population. These findings suggest preservation and restoration of cerebral perfusion may limit cognitive decline.Disclosure: Dr. Wolters has nothing to disclose. Dr. Zonneveld has nothing to disclose.
