The Morbid Impact of Environmental Toxins on the Human Nervous System: Peripheral Neuropathy Nexus with Organic Solvents, Pesticides, and Heavy Metals

Abstract

Peripheral neuropathy is a complex disorder characterized by damage to the peripheral nerves, resulting in various sensory, motor, and autonomic symptoms. This review offers a detailed examination of peripheral neuropathy, covering its prevalence, effects on individuals and society, causes, diagnosis, mechanisms, treatment, and management, focusing on its association with environmental toxins. The etiology of peripheral neuropathy is multifactorial, encompassing diverse causes such as diabetes mellitus, autoimmune diseases, infections, vitamin deficiencies, toxic exposures, and genetic factors. Notably, environmental toxins, including organic solvents, pesticides, and heavy metals, have been implicated in the pathogenesis of peripheral neuropathy. Environmental toxins exert their neurotoxic effects through various mechanisms, including disruption of neuronal membrane integrity, interference with neurotransmission, induction of oxidative stress, and promotion of inflammatory responses. Accurate diagnosis of peripheral neuropathy involves a comprehensive medical history, neurological examination, electrophysiological studies, imaging tests, and laboratory investigations to identify underlying causes, including environmental toxin exposure. Treatment strategies for environmental toxin-induced peripheral neuropathy focus on eliminating exposure, managing symptoms, and preventing further nerve damage. Pharmacological interventions, adjunctive therapies, nutritional support, regular monitoring, and patient education are integral to management. A multidisciplinary approach is fundamental for diagnosing and managing peripheral neuropathy effectively, emphasizing identifying and mitigating environmental toxin exposure to alleviate symptoms and improve quality of life.
