What is neurological poisoning?
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 poison causes neurological problems?
Common toxins that cause neuropathy include: exposure to lead, mercury, arsenic and thalium. Some organic insecticides and solvents can result in neuropathies. Sniffing glue or other toxic compounds can also cause peripheral neuropathy.
What poison attacks the nervous system?
In larger doses, botulinum, which is produced by Clostridium botulinum bacteria, is a deadly poison. Neurotoxin, substance that alters the structure or function of the nervous system.
What toxins cause brain damage?
Common toxic substances that lead to injury include:
- Mercury.
- Lead.
- Solvents such as paint thinners.
- Pesticides.
- Manganese.
- Hydrogen sulfide.
- Methane gas.
Can you recover from chemical neuropathy?
Clinical signs usually appear weeks after exposure has commenced; the condition continues to evolve after chemical exposure has ceased, and recovery spans a period of months or years.
How is toxic neuropathy treated?
In addition to advising the patient to avoid the causative drug or occupational or environmental toxin, management of toxic neuropathy can include the following: Nonpharmacologic measures: Cool soaks, heat, massage, elevation or lowering of the limbs, and/or exercise. Tricyclic antidepressants. Anticonvulsants.
Can you recover from neurotoxicity?
Exposure to neurotoxins can be fatal in some cases, while in others, patients survive but may not completely recover. In other cases, patient do completely recover after receiving treatment.
What kind of toxins can cause neuropathy?
Toxins, poisons and chemicals can cause peripheral neuropathy. This can happen through drug or chemical abuse or through exposure to industrial chemicals in the workplace or in the environment (after either limited or long-term exposure). Common toxins that cause neuropathy include: exposure to lead, mercury, arsenic and thalium.
What is the cause of shellfish poisoning in humans?
Neurotoxic shellfish poisoning is caused by a red-tide producer that was first identified in 1880 from Florida, with earlier historical references. It causes sickness in humans lasting several days. Although not fatal to humans, neurotoxic shellfish poisoning is known to kill fish, invertebrates, seabirds, and marine mammals (e.g., manatees).
What causes a person to have a neurological disorder?
If you suspect that you or a loved one may be suffering from one of these issues, you may also be wondering about what causes a neurological disorder. The causes of such dysfunction can be quite diverse. Both the spinal cord and brain are insulated by numerous membranes that can be vulnerable to force and pressure.
How does exposure to pesticides affect the nervous system?
However, exposure to certain chemicals, like pesticides, can cause neurotoxic effects or exacerbate preexisting chemical damage to the nervous system.

What can cause a person to be poisoned by arsenic?
Also, groundwater can contain runoff from industrial plants. Drinking arsenic-laden water over a long period of time can lead to poisoning. Other possible causes of arsenic poisoning can include: breathing air that contains arsenic.
What are some of the effects of lead poisoning?
Memory loss. Pain or tingling in the hands and/or feet. Weak. Because these symptoms may occur slowly or may be caused by other things, lead poisoning can be easily overlooked. Exposure to high levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death.
Which toxic compound is most known to cause neurological problems in humans?
Methyl bromide is a highly toxic gas that is used widely as an insecticidal fumigant for dry foodstuffs. It can be toxic to both the CNS and the peripheral nervous system [29,30]. Most neurological manifestations of methyl bromide intoxication occur as a result of inhalation.
How does poison affect the brain?
Environmental toxins can impact the developing brain through various mechanisms. Some toxins, such as mercury, cause cell death and alter cell migration and cell proliferation (101, 104). Lead disrupts neurotransmission, synaptogenesis, and synaptic trimming (101, 104, 110).
What toxins affect the brain?
Many toxins, such as lead, PCBs, bisphenol A, manganese, and mercury, disrupt dopamine or dopaminergic neurons in the prefrontal cortex (1, 57, 110).
Can you recover from toxic brain damage?
Recovering from a severe TBI can take a long time. Some people regain consciousness within a few days or weeks and recover quickly. Others progress more slowly and may remain in a state of impaired consciousness for months or years.
