Abstract:
Neurotoxic disease can mimic many common neurologic disease states, including parkinsonism, myelopathy, neuropathy, and encephalopathy. Accurate diagnosis and appropriate treatment may result in a favorable outcome. This review highlights 5 areas of neurotoxicology for which there is an emerging understanding of disease processes or patterns of exposure, including 3 specific metal toxicities (manganism, zinc-induced copper deficiency, and cobalt-chromium neuropathy). Toxin-induced posterior reversible encephalopathy syndrome is more widely recognized and reported in association with an ever-growing list of drugs. Two new categories of street drugs, synthetic cathinones and cannabinoids, have been identified as public health threats due to their popularity, availability, and severity of toxicity.
Insights
Neurotoxic diseases can mimic common neurological conditions. This review covers emerging neurotoxicology areas, including metal toxicities and new street drugs, aiding diagnosis and treatment.
Area of Science:
- Neurotoxicology
- Neurology
- Toxicology
Background:
- Neurotoxic diseases often present with symptoms similar to common neurological disorders like parkinsonism, myelopathy, neuropathy, and encephalopathy.
- Timely diagnosis and effective treatment are crucial for managing neurotoxic conditions and achieving positive patient outcomes.
Purpose of the Study:
- To review emerging areas in neurotoxicology with a focus on new disease processes and exposure patterns.
- To highlight specific metal toxicities and novel neurotoxins posing public health risks.
Main Methods:
- Literature review of recent advancements in neurotoxicology.
- Identification and analysis of emerging neurotoxic agents and associated conditions.
Main Results:
- Discussion of three specific metal toxicities: manganism, zinc-induced copper deficiency, and cobalt-chromium neuropathy.
- Recognition of toxin-induced posterior reversible encephalopathy syndrome (PRES) linked to a growing list of drugs.
- Identification of synthetic cathinones and cannabinoids as significant public health threats due to widespread use and severe toxicity.
Conclusions:
- Accurate diagnosis of neurotoxic diseases is essential for favorable outcomes.
- Emerging neurotoxic agents, including metals and novel synthetic drugs, require increased awareness and understanding.
- Continued research into neurotoxicology is vital for public health protection.
