Definition. Neurotoxicity occurs when the exposure to natural or manmade toxic substances (neurotoxicants) alters the normal activity of the nervous system. This can eventually disrupt or even kill neurons, key cells that transmit and process signals in the brain and other parts of the nervous system.

What do neurotoxins do to the body?
Macroscopic manifestations of neurotoxin exposure can include widespread central nervous system damage such as intellectual disability, persistent memory impairments, epilepsy, and dementia. Additionally, neurotoxin-mediated peripheral nervous system damage such as neuropathy or myopathy is common.
What is a neurotoxin in medicine?
Medical Definition of neurotoxin
: a poisonous substance (such as tetrodotoxin or saxitoxin) that acts on the nervous system and disrupts the normal function of nerve cells.
Which drugs are neurotoxic?
Ecstasy (MDMA) and stimulant amphetamines (METH and AMPPI) are popular drugs of abuse and they are neurotoxic in animal studies.
Are neurotoxins painful?
The clinical signs and symptoms of neurotoxic poisoning may be expressed in the central, the peripheral and the autonomic nervous systems, and in skeletal muscle. They are often associated with pain, changes in the special senses of taste and smell, as well as changes in visual acuity and hearing.
What is a neurotoxicity test?
Neurotoxicity testing is used to identify potential neurotoxic substances. Sometimes neurotoxicity testing is considered as a component of target organ toxicity; the central nervous system (CNS) being one of the major target organ systems.
What does a Hemotoxin do?
Hemotoxins cause hemolysis, the destruction of red blood cells (erythrocytes), or induce blood coagulation (clotting).
Can neurotoxicity go away?
The prognosis depends upon the length and degree of exposure and the severity of neurological injury. In some instances, exposure to neurotoxins or neurotoxicants can be fatal. In others, patients may survive but not fully recover. In other situations, many individuals recover completely after treatment.
Can neurotoxicity be reversed?
Additionally, seizures, extrapyramidal symptoms, action myoclonus, and quadriparesis have been reported. In patients with neurological signs, cyclosporine levels are usually outside the normal range, and after lowering the dose or withholding administration, neurotoxicity clears in most cases.
How does the body get rid of neurotoxins?
Most toxins are fat-soluble and therefore highly attracted to fat. The sauna, heating, exercise, and other things we are giving you are breaking down this fat, and therefore helpfully releasing these toxins so they can be removed from your body.
Is nicotine a neurotoxin?
Nicotine itself is a dangerous neurotoxin, even if it weren't addictive. To start, nicotine is poisonous if ingested and is one of the most toxic of all poisons. In fact, even handling the plant leaves can cause health problems such as headache, nausea, vomiting, and fatigue.
Is alcohol a neurotoxic?
Studies clearly indicate that alcohol is neurotoxic, with direct effects on nerve cells. Chronic alcohol abusers are at additional risk for brain injury from related causes, such as poor nutrition, liver disease, and head trauma.
What causes neurotoxicity?
Neurotoxicity can result from exposure to substances used in chemotherapy, radiation treatment, drug therapies, and organ transplants, as well as exposure to heavy metals such as lead and mercury, certain foods and food additives, pesticides, industrial and/or cleaning solvents, cosmetics, and some naturally occurring ...
What is acute neurotoxicity?
The objective of the acute neurotoxicity study is to determine potential neurotoxicity of the active substance (major neurobehavioural and neuropathological effects) after single exposure.
