Common diabetes drug tested to protect HIV Patients' brains

This small pilot study tested whether metformin, a common and affordable diabetes medication, could improve blood vessel function and blood flow in the brains of people living with HIV who also have metabolic syndrome. The researchers enrolled 30 participants in South Africa who took metformin for 12 weeks. The goal was to see if this well-known drug could help reduce brain blood vessel damage and inflammation linked to a higher risk of future memory problems and dementia.
