Researchers have identified nine risk factors during different stages in life that may increase a person's likelihood of developing dementia. At least 35% of dementia cases, researchers say, may be directly linked to these risk factors. By taking steps to reduce risks and by improving education, it is estimated that the incidence of dementia can be reduced by as much as 20%.
USC researchers reveal schizophrenia may be due to a disruption in the brain's entire communication system, not just the temporal and prefrontal lobes.
Study points to the evolutionary and developmental similarities between sensory cells in the inner ear and skin.
Damaged capillaries in the brain may set the stage for the development of Alzheimer's disease, years before symptoms appear.
Older women exposed to higher levels of air pollution were more likely to experience greater memory decline and Alzheimer's-like brain atrophy compared with those exposed to cleaner air.
A new study reports leaky capillaries in the brain may be an early sign of Alzheimer's disease as it can signal cognitive impairment prior to the buildup of proteins associated with the neurodegenerative disease.
Studying human-machine interactions, researchers found that during the pandemic, people are not only more altruistic to other humans, their behaviors also extend to machines. This may be explained by the growing popularity of digital assistants, such as Alexa.
Vascular cell loss results in neuron loss, researchers report. However, pericytes secrete a substance that helps protect neurons, even when vascular cell degeneration begins to occur.
The brain regulates hunger and appetite by releasing a neuropeptide through cerebrospinal fluid, researchers report.
