According to researchers, a simple MRI brain scan could help diagnose people with a common cognitive disorder.
A new study reports that, regardless of gender, young adults who are more aerobically fit have greater volume of the entorhinal cortex, an area of the brain implicated in memory.
APOE4, a gene implicated as a risk factor for Alzheimer's disease, triggers leaks in the blood-brain barrier. The damage to capillaries APOE4 causes correlates with increased levels of cyclophilin, a protein that causes the inflammation that is a signature of early Alzheimer's.
UCLA researchers report sleep deprivation prevents neurons from correctly connecting with each other, resulting in temporary cognitive lapses in visual perception and memory.
Researchers have identified average levels of biological and anatomical brain changes associated with Alzheimer's disease over thirty years before symptoms appear. In those with genetic risk factors for Alzheimer's, researchers found changes in cognitive performance up to 15 years before becoming symptomatic. Changes in Tau levels in the cerebral spinal fluid appeared up to 34 years before dementia symptoms occurred, and physical changes to the medial temporal lobe were apparent up to 9 years before cognitive impairment was apparent.
Stimulating specific regions of the brain can help to improve memory and word recall in those with severe epilepsy, a new Nature Communications study reports.
A new study suggests hippocampus is dedicated to memory formation, and not spatial skills.
Kumamoto University researchers reveal people with MCI have a harder time memorizing human faces that their aging peers without the disorder. Additionally, researchers note, those with mild cognitive impairment express different gaze behavior while trying to memorize a face.
