This multicenter randomized controlled trial investigated neural abnormalities in attention networks among 41 hypertensive patients with cognitive impairment using ultra-high-field 7T MRI. The study found that structural atrophy and dysfunction in attention networks correlated with poorer cognitive performance, with hyperconnectivity in specific hubs linked to decreased processing speed.
Key findings
- Structural atrophy related to cognitive impairment was found in attention network regions.
- Dysfunction in attention networks was associated with worse global cognitive performance.
- Hyperconnectivity in attention network hubs correlated with declined processing speed.
Why it matters
Understanding the neural mechanisms linking hypertension and cognitive impairment can inform future interventions. Identifying specific network abnormalities may lead to targeted therapeutic strategies to mitigate cognitive decline in hypertensive patients.
