Many diseases may be neurological or psychiatric and may primarily affect the brain. Others may affect many other organs, like HIV, Hashimoto's thyroiditis causing hypothyroidism, or cancer. According to a 2015 report in The American Scholar, an assortment of neglected tropical diseases as well as some recently identified pathogens such as ...
An acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder. It usually affects cognitive, physical, emotional, social or independent functioning. ABIs can result from either a traumatic brain injury or a non-traumatic injury such as stroke, infection or substance abuse.
Additionally, lack of sleep causes increased anxiety-like behaviors and impairs the brain's ability to block out unimportant stimuli when performing tasks requiring attention. Disruptions in important brain circuits and the downregulation of proteins necessary for cognitive stability are the causes of these behavioral abnormalities. [30]
“Of importance, if sleep apnea affects the brain health and increases the risk for dementias, then treatment of it can serve as a strategy to improve brain health and prevent these disorders ...
Its deficiency may cause swelling of the intracellular space and local disruption of the blood-brain barrier. Brain tissue is very sensitive to changes in electrolytes and pressure and edema can be cytotoxic. In Wernicke this occurs specifically in the mammillary bodies, medial thalami, tectal plate, and periaqueductal areas.
They are defined by deficits in cognitive ability that are acquired (as opposed to developmental), typically represent decline, and may have an underlying brain pathology. [1] The DSM-5 defines six key domains of cognitive function: executive function, learning and memory, perceptual-motor function, language, complex attention, and social ...
Focal neurologic signs, also known as focal neurological deficits or focal CNS signs, are impairments of nerve, spinal cord, or brain function that affects a specific region of the body, e.g. weakness in the left arm, the right leg, paresis, or plegia.
Cerebral infarction – A "stroke", caused by complete oxygen deprivation due to an interference in cerebral blood flow which affects multiple areas of the brain. Cerebral hypoxia can also be classified by the cause of the reduced brain oxygen: [23] Hypoxic hypoxia – Limited oxygen in the
