For instance, changes in serum and central nervous system (CNS) levels of iron and in proteins mediating iron metabolism have been documented in patients grappling with the aforementioned diseases.

Furthermore, we discuss how targeting iron metabolism can be an effective therapeutic option to tackle this class of diseases.
