What is delayed toxicity?

What is delayed toxicity?

Delayed health effects may take months or years to appear and can result from either acute or chronic exposure to a toxic substance. The delay between the exposure and the appearance of health effects is called the latency period. Delayed health effects can be reversible or permanent.

What toxin affects the nervous system may damage the brain?

Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol (drinking alcohol), glutamate, nitric oxide, botulinum toxin (e.g. Botox), tetanus toxin, and tetrodotoxin.

Which factors determine whether exposure to a chemical will have a toxic effect?

The toxicity of a substance depends on three factors: its chemical structure, the extent to which the substance is absorbed by the body, and the body’s ability to detoxify the substance (change it into less toxic substances) and eliminate it from the body. Are “toxic” and “hazardous” the same?

What is reversible toxicity?

The effects may be reversible (when the toxic agent has been removed) or irreversible. The effects may also be acute, subacute, or subchronic.

How do you know if you have neurotoxicity?

Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness, loss of memory, vision, and/or intellect, uncontrollable obsessive and/or compulsive behaviors, delusions, headache, cognitive and behavioral problems and sexual dysfunction.

What are the signs and symptoms of neurotoxicity?

Symptoms may appear immediately after exposure or be delayed. They may include limb weakness or numbness; loss of memory, vision, and/or intellect; headache; cognitive and behavioral problems; and sexual dysfunction. Individuals with certain disorders may be especially vulnerable to neurotoxicants.

What is the prognosis of neurotoxic toxicity?

Prognosis. The prognosis depends upon the length and degree of exposure and the severity of neurological injury. In some instances, exposure to neurotoxicants can be fatal. In others, patients may survive but not fully recover. In other situations, many individuals recover completely after treatment.

What happens to neurones after exposure to neurotoxins?

Increased rate of loss of neurones following exposure to a neurotoxin producing symptomatic neurological disease at an earlier stage. Reproduced from Kobayashi and Suzuki, 5 with permission. In the adult, the nervous system is protected by the blood–brain and blood–axon barriers.

What is neoneurotoxicity and how can it affect you?

Neurotoxicity is the poisoning of the brain and nervous system. It’s linked to a wide range of neurological symptoms and disorders.
