17 Nov 2022 --- Japan-based researchers have explored the potential role iron supplementation has on the increased risk of parkinsonism. The longitudinal study, including nearly 386,000 participants, found that excessive iron consumption was “significantly associated with higher Parkinson’s risk.” The researchers explain that Parkinson’s disease (PD) is a “progressive neurological disorder caused by the degeneration of dopaminergic neurons” in a part of the brain – Substantia Nigra (SN). Characterized mainly by impaired motor functions, it may develop into cognitive dysfunction and other neurological deficits.
