Neurotoxic Effects of Environmental Pollutants and Pharmacological Neuroprotective Strategies

Abstract

Environmental pollutants have emerged as silent neurotoxins contributing to a wide spectrum of neurological disorders, both acute and chronic. These pollutants—ranging from heavy metals and pesticides to airborne particulates—pose significant risks to human health, particularly affecting the central and peripheral nervous systems. The vulnerability of the nervous system to environmental toxins is rooted in its complex and delicate structure, and its limited regenerative capacity. Neurotoxicity can manifest in behavioral, cognitive, and motor impairments, with long-term implications that can span generations. This paper aims to examine the mechanisms through which various environmental pollutants exert neurotoxic effects and to explore the pharmacological neuroprotective strategies that may mitigate these adverse outcomes. A comprehensive review of existing literature, current challenges, and future scope of neuroprotective pharmacology is discussed to foster better understanding and intervention techniques.
