Neurotoxic

Neurotoxicity refers to damage to the brain or peripheral nervous system caused by exposure to natural or man-made toxic substances. These neurotoxins alter the activity of the nervous system in ways that can disrupt or kill nerves. Nerves are essential for transmitting and processing information in the brain, as well as for controlling the functions of the body.

Causes

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 substances. Alcohol and tobacco also have neurotoxic properties.

Symptoms

Symptoms of neurotoxicity can be as mild as a headache or as severe as seizures. Other symptoms can include impaired cognitive function, changes in personality, and problems with coordination and balance. In severe cases, neurotoxicity can result in death.

Treatment

Treatment of neurotoxicity depends on the cause. In some cases, removing the exposure to the neurotoxin can resolve the symptoms. In other cases, medications or other treatments may be needed to manage the symptoms.
