One cause of cognitive decline with age

The discovery that a particular type of dendritic spine is lost with age not only provides a target for therapy, but also emphasizes the importance of building skills and expertise when young.

A rhesus monkey study has revealed which dendritic spines are lost with age, providing a new target for therapies to help prevent age-association cognitive impairment.
Why older adults remember the good times better

An imaging study has found differences in brain activity that explain why older adults are better at remembering positive events.

The secret of sharp memory in old age

Examination of the brains from 9 “super-aged” — people over 80 whose memory performance was at the level of 50-year-olds — has found that some of them had almost no tau tangles. Are they genetically protected, or reaping the benefits of a preventive lifestyle?

Personality may influence brain shrinkage in aging
  • An imaging study involving 79 volunteers aged 44 to 88 has found more brain atrophy and faster rates of decline in brain regions particularly affected by aging, among those ranked high in neuroticism traits.

Memory decline linked to an inability to ignore distractions

A new study provides more support for the idea that cognitive decline in older adults is a product of a growing inability to ignore distractions, and that forewarning doesn't help.

Gene variant may protect memory and thinking skills in older people

The role of the dopamine-regulating COMT gene in cognitive function has been the subject of debate. Now a large study of older adults has revealed that the Met variant of the COMT gene was linked to a greater decline in cognitive function. This effect was more pronounced for African-Americans.

The role of the catechol-O-methyltransferase (COMT) gene in cognitive function has been the subject of some debate. The gene, which affects
