Higher fish intake is linked to lower cerebrovascular disease burden in older adults

Takeaway

  • Older people without stroke or dementia who have a higher fish intake have a reduced global cerebrovascular disease burden based on magnetic resonance imaging.

Why this matters

  • Although the benefits of fish intake on prevention of cerebrovascular disease are widely recognized, the underlying mechanisms relating to subclinical damage are unknown.

  • The findings of this novel study are important because few protective factors against the development of subclinical cerebrovascular damage that lead to stroke or dementia have been identified. The findings suggest that fish intake has a beneficial effect on brain vascular health before manifestation of overt disease, representing simple and inexpensive preventive strategies.
