Brain health in atrial fibrillation

Participation involves one screening visit (~45 min) at the University of Auckland, Park Road, Grafton and one MRI scan visit (~1 ½ hours) at the Centre for Advanced MRI (CAMRI).

• Screening visit: Height, weight and blood pressure measurements will be collected. Additionally there will be some cognitive testing performed on an iPad.
  
• MRI scan visit: Various images of your brain will be taken, including anatomical and functional blood flow images whilst you perform two different tasks (a visual task where you will watch a flickering checkerboard, and a breathing task where you will breathe air enriched with a small amount of carbon dioxide (5%) for a short period of time). Images of your heart will also be taken. 

• People aged 55 years and over.
• People with a normal heart rhythm.
• People who are healthy with no significant medical conditions.
• People not taking any prescription or over-the-counter medications (other than the oral contraceptive pill).
