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 ...
The brain converts heroin into morphine, which binds to molecules on cells in the brain and body called opioid receptors that affect how we perceive pain and rewards. This explains the surging ...
In 1986, it was presumed that permanent brain damage may result from chronic use of benzodiazepines similar to alcohol-related brain damage. [70] In 1987, 17 inpatient people who used high doses of benzodiazepines non-medically have anecdotally shown enlarged cerebrospinal fluid spaces with associated cerebral atrophy. Cerebral atrophy ...
A 2015 review concluded that "Nicotine acts as a gateway drug on the brain, and this effect is likely to occur whether the exposure is from smoking tobacco, passive tobacco smoke or e-cigarettes." [25] Nicotine may have a profound impact on sleep. [26] The effects on sleep vary after being intoxicated, during withdrawal, and from long-term use ...
A link between these types of drugs and cognitive impairment isn't a totally new discovery, but for the first time, researchers used brain imaging techniques to determine the physical changes ...
Binge drinking regimes are associated with causing an imbalance between inhibitory and excitatory amino acids and changes in monoamine release in the central nervous system, which increases neurotoxicity; this may result in cognitive impairments, psychological problems, and may cause irreversible brain damage in both adolescent and adult long-term binge drinkers.
More specifically, it looked at the effect of methylphenidate (brand names Ritalin, Concerta), a stimulant, and atomoxetine (Strattera), a non-stimulant, on the brain. It concluded that both drugs ...
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
