Abstract

Objective: To detect white matter microstructural alterations in patients with primary aldosteronism (PA) with normal cognitive function using diffusion tensor imaging (DTI).

Methods: This study included PA patients and normotensive healthy controls (HCs). MRI (T1-weighted) and DTI data were collected for all participants. Using the Johns Hopkins University white matter fiber tractography template, we calculated the values of fractional anisotropy (FA), axial diffusivity (AD), radial diffusivity (RD), and mean diffusivity (MD).

Results: Compared to the HC group, the PA group showed significant increases in AD in cingulum bundle cingulate part (CgC.R), forceps minor (FMi), bilateral inferior fronto-occipital fasciculi (IFO), and right temporo-superior longitudinal fasciculus (tSLF.R); RD in left IFO (IFO.L) and right superior longitudinal fasciculus (SLF.R); and MD in FMi, IFO.L, right IFO (IFO.R) and SLF.R.

Conclusion: Compensatory white matter alterations occur in PA patients before cognitive impairment. These alterations may serve as early imaging biomarkers for PA-related brain function impairment, highlighting the importance of advanced neuroimaging for early diagnosis and intervention.

期刊介绍： The International Journal of General Medicine is an international, peer-reviewed, open access journal that focuses on general and internal medicine, pathogenesis, epidemiology, diagnosis, monitoring and treatment protocols. The journal is characterized by the rapid reporting of reviews, original research and clinical studies across all disease areas. A key focus of the journal is the elucidation of disease processes and management protocols resulting in improved outcomes for the patient. Patient perspectives such as satisfaction, quality of life, health literacy and communication and their role in developing new healthcare programs and optimizing clinical outcomes are major areas of interest for the journal. As of 1st April 2019, the International Journal of General Medicine will no longer consider meta-analyses for publication.
