People who drink between 4 - 6 cups of coffee or tea per day have a lower risk of stroke and dementia, researchers report. Drinking coffee alone, or in combination with tea, was associated with lower risk of post-stroke dementia.
A study of genetic data from people with autism and congenital heart disease identified 23 genes associated with heart disease. 12 of the genes were previously unknown.
Repetitive transcranial magnetic stimulation (rTMS) applied to the left prefrontal cortex can improve episodic memory performance by reducing the power of low frequency of brain waves during memory formation.
Amyloid-beta proteins created in the liver are carried in the blood by lipoproteins to the brain. This results in neurodegeneration, brain atrophy, and inflammation, which are common features of Alzheimer's disease.
Reductions in reaction time, memory, and other neuropsychological problems persist for at least seven days following a ten-day period of insufficient sleep.
A new genetics study reveals shared genetic sites relevant to facial shapes and features between Tanzanian children and Europeans, suggesting the genetic basis for human face shape is partly shared across different populations.
Those who subscribe to the theory of Social Darwinism tend to be more hostile to others, admire power, are more exploitative, and have lower self-esteem, researchers say.
A new study found a person's math ability was linked to levels of GABA and glutamate in the brain. In children, greater math fluency was associated with higher GABA levels in the left intraparietal sulcus, while lower levels of GABA were linked to math ability in adults. The reverse was true for glutamate in both children and adults.
Depleting the protein ADORA2B from the blood of mice led to faster cognitive decline, decreased auditory processing, and increased brain inflammation.
The connection between brain activity during sleep and cerebrospinal fluid flow was reduced in those with risk factors for dementia and those with Alzheimer's disease than in the healthy control group.
