This deposited free iron exerts a ferroptosis pathway, resulting in lipid peroxidation (LiPr).

Due to the iron homeostasis balance disruption, the brain gets adversely affected which further causes neurodegenerative diseases (NDDs) like Parkinson's and Alzheimer's disease, strokes, and brain tumors like glioblastoma (GBS), and glioma.
