The Association Between Primary Aldosteronism and Cognitive Dysfunction

Recruiting now

Conditions studied: Primary Aldosteronism, Cognitive Dysfunction, Mild Cognitive Impairment (MCI), Dementia

In brief

The goal of this observational study is to learn about the prevalence, progression, and influencing factors of cognitive impairment in patients with primary aldosteronism (PA). The main questions it aims to answer are: 1. What is the prevalence of baseline cognitive impairment in PA patients and what factors are associated with it? 2. What is the incidence of cognitive progression in PA patients within 1 and 5 years of follow-up and what factors influence this progression? Participants who are already diagnosed with PA as part of their regular medical care will be invited to join this long-term study. They will complete regular cognitive tests, medical check-ups, and questionnaires for up to 5 years. Some participants will also have optional blood tests and brain scans to help researchers understand the causes behind any cognitive changes.
