The blood–brain barrier (BBB) is one critical example of protection which prevents toxins and other adverse compounds from reaching the brain. [22] As the brain requires nutrient entry and waste removal, it is perfused by blood flow.
In some cases the level or exposure-time may be critical, with some substances only becoming neurotoxic in certain doses or time periods. Some of the most common naturally occurring brain toxins that lead to neurotoxicity as a result of long term drug use are amyloid beta (Aβ), glutamate, dopamine, and oxygen radicals.
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 ...

A new study in mice suggests the hypothesis that brain-cleansing occurs during sleep may be inaccurate. The findings show that mice cleaned more toxins and metabolites from the brain when they ...
Another damaging result of excess calcium in the cytosol is the opening of the mitochondrial permeability transition pore, a pore in the membranes of mitochondria that opens when the organelles absorb too much calcium. Opening of the pore may cause mitochondria to swell and release reactive oxygen species and other proteins that can lead to ...
Vitamin B 3, also known as niacin, includes both nicotinamide as well as nicotinic acid, both of which function in many biological oxidization and reduction reactions within the body. Niacin is involved in the synthesis of fatty acids and cholesterol, known mediators of brain biochemistry, and in effect, of cognitive function. [21]
