Researchers have found that certain types of specializations on nerve cells called "spines" are depleted as a person ages, causing cognitive decline in the part of the brain that mediates the highest levels of learning. These spines receive an important class of synapses that are involved with the process of learning.

Alcohol use and cognitive decline among the elderly
There are few studies of alcohol use among the elderly. A study of drinking among the elderly in Brazil has found that heavy alcohol use is associated with more memory and cognitive problems than mild-to-moderate alcohol use, especially among women. Mild-to-moderate alcohol use was associated with lower cognitive disorder rates than no alcohol use, also among women.

New compound improves cognitive decline, symptoms of Alzheimer’s disease in rodents
A fast-acting compound that appears to improve cognitive function impairments in mice similar to those found in patients with progressive Alzheimer's disease has been identified by scientists. Researchers hope to one day replicate the result in humans.

Healthy older adults with subjective memory loss may be at increased risk for MCI and dementia
Subjective cognitive impairment (SCI), the earliest sign of cognitive decline, is marked by situations such as when a person recognizes they can't remember a name like they used to or where they recently placed important objects the way they used to. A new study finds that healthy older adults reporting SCI are 4.5 times more likely to progress to the more advanced memory-loss stages of mild cogn

Cognitive dysfunction reversed in mouse model of Down syndrome
At birth, children with Down syndrome aren't developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development. Scientists have now demonstrated a possible new approach to slowing the inevitable progression of cognitive decline found in Down syndro

Androgen's effects on older female cognitive functioning
Nowadays there seems to be a growing concern for age-related decline evidenced by the countless number of ads promising brain enhancement through the guise of drugs and nutrients. In addition, studies have shown that female mice exhibit more severe cognitive decline compared to age-matched male mice. So does this mean women should be more vigilant of their brain health and head for the pharmacies

Higher Adherence To Mediterranean Diet Associated With Slower Cognitive Decline
In an examination of the association between adherence to a Mediterranean-type diet and cognitive performance and risk of dementia, researchers found that high adherence to the diet was associated with slower decline in some measures of cognitive function but was not associated with decreased risk for dementia, according to a study in the August 12 issue of JAMA.

Patients With Common Brain Tumours May Have Poorer Cognitive Function After Receiving Radiotherapy
An article published Online first and in an upcoming edition of The Lancet Neurology reports that although low doses of radiotherapy are considered as safe; they may contribute to progressive cognitive decline in patients with low-grade glioma brain tumours. The most common type of brain cancer is Low-grade glioma (LGG) brain tumour. Early or delayed radiotherapy is the most frequent treatment.
