Excitotoxicity may be involved in cancers, spinal cord injury, stroke, traumatic brain injury, hearing loss (through noise overexposure or ototoxicity), and in neurodegenerative diseases of the central nervous system such as multiple sclerosis, Alzheimer's disease, amyotrophic lateral sclerosis (ALS), Parkinson's disease, alcoholism, alcohol ...
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
When referring to a disease, encephalopathy refers to a wide variety of brain disorders with very different etiologies, prognoses and implications. For example, prion diseases, all of which cause transmissible spongiform encephalopathies , are invariably fatal, but other encephalopathies are reversible and can have a number of causes including ...
The specific causes of neurological problems vary but can include genetic disorders, congenital abnormalities or disorders, infections, lifestyle, or environmental health problems such as pollution, malnutrition, brain damage, spinal cord injury, nerve injury, or gluten sensitivity (with or without intestinal damage or digestive symptoms).
The nervous tissue found in the brain, spinal cord, and periphery comprises an extraordinarily complex biological system that largely defines many of the unique traits of individuals. As with any highly complex system, however, even small perturbations to its environment can lead to significant functional disruptions.
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 ...
The blood–spinal cord barrier (BSCB) is a semipermeable anatomical interface that consists of the specialized small blood vessels that surround the spinal cord. While similar to the blood–brain barrier in function and morphology, it is physiologically independent and has several distinct characteristics. [ 1 ]
The brain and spinal cord, which make up the CNS, are not usually accessed directly by pathogenic factors in the body's circulation due to a series of endothelial cells known as the blood–brain barrier, or BBB. The BBB prevents most infections from reaching the vulnerable nervous tissue.
