[4] [14] GS, in the brain, is found primarily in astrocytes. [15] Astrocytes protect neurons against excitotoxicity by taking up excess ammonia and glutamate. [14] In hyperammonemic environments (high levels of ammonia), astroglial swelling occurs. [14] [16] [17] Different perspectives have approached the problem of astroglial swelling.
Males with mild cognitive impairment tend to show more microstructural damage than females with MCI, but seem to have a greater cognitive reserve due to larger absolute brain size and neuronal density. As a result, women tend to manifest symptoms of cognitive decline at lower thresholds than men do. [107] This effect seems to be moderated by ...
Age dynamics of the body mass (1, 2) and mass normalized to height (3, 4) of men (1, 3) and women (2, 4) [25] Comparison of a normal aged brain (left) and a brain affected by Alzheimer's disease. A number of characteristic ageing symptoms are experienced by a majority, or by a significant proportion of humans during their lifetimes.

It's possible that sundowning in dementia patients is caused by a combination of hormonal changes, brain deterioration or damage that has occurred, environmental factors, disruption to a person's ...
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
Adding more brain-healthy habits into our lives, such as eating blueberries, sleeping on our left side and even getting the shingles vaccine can help, as can avoiding factors that can accelerate ...
