A 2015 study found gadolinium deposited in the brain tissue of people who had received gadodiamide. [8] Other studies using post-mortem mass spectrometry found most of the deposit remained at least 2 years after an injection and deposit also in individuals with no kidney issues. In vitro studies found it to be neurotoxic. [9]
It is advised that the use of gadolinium-based media should be based on careful consideration of the retention characteristics of the contrast, with extra care being taken in patients requiring multiple lifetime doses, pregnant, and paediatric patients, and patients with inflammatory conditions.
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 ...
Gadopiclenol was approved for medical use in the United States in September 2022 by the Food and Drug Administration. [2] [12]In October 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Elucirem, intended for contrast-enhanced ...
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]

Nephrogenic systemic fibrosis is a rare syndrome that involves fibrosis of the skin, joints, eyes, and internal organs. NSF is caused by exposure to gadolinium in gadolinium-based MRI contrast agents (GBCAs) in patients with impaired kidney function.
The magnitude of ethanol neurotoxicity in fetuses leading to fetal alcohol syndrome has been shown to be dependent on antioxidant levels in the brain such as vitamin E. [108] As the fetal brain is relatively fragile and susceptible to induced stresses, severe deleterious effects of alcohol exposure can be seen in important areas such as the ...
