Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...
This rebound causes hyperexcitability of neurotransmission systems. If this hyperexcitability state occurs multiple times, kindling and neurotoxicity can occur leading to increased alcohol-related brain damage. Damaging excitotoxicity may also occur as a result of repeated withdrawals. Similar to people who have gone through multiple ...
Excitotoxicity can occur from substances produced within the body (endogenous excitotoxins).Glutamate is a prime example of an excitotoxin in the brain, and it is also the major excitatory neurotransmitter in the central nervous system of mammals. [14]
This group of persistent health symptoms are called syndrome of irreversible lithium-effectuated neurotoxicity (SILENT). [9] The syndrome presents with irreversible neurological and neuro-psychiatric effects. [10] The neurological signs are cerebellar dysfunction, extrapyramidal symptoms, and brainstem dysfunction. [11]
Common symptoms of TTX consumption include paraesthesia (often restricted to the mouth and limbs), muscle weakness, nausea, and vomiting [55] and often manifest within 30 minutes of ingestion. [57] The primary mechanism by which TTX is toxic is through the inhibition of sodium channel function, which reduces the functional capacity of neuron ...
Symptoms may also be dependent on the form of vitamin B 6 taken in supplements. [27] [35] ... producing energy, preventing neurotoxicity, or treating asthma. ...
Ben Tarver, 29, began having seizures and panic attacks in September before exhibiting symptoms of paranoia. By the middle of October, he was diagnosed with Anti-NMDA Receptor Encephalitis, a rare ...
Olney's lesions, also known as NMDA receptor antagonist neurotoxicity (NAT), is a form of brain damage consisting of selective death of neurons but not glia, observed in restricted brain regions of rats and certain other animal models exposed to large quantities of psychoactive drugs that inhibit the normal operation of the neuronal NMDA receptor.
