Brain Atrophy

Omega-3 fatty acids could preserve brain health

Those with higher levels of omega-3 fatty acids, which are found in fish oil, appear to have larger brain volumes in old age, according to a new study in Neurology. Shrinking brain volume can be a sign of Alzheimer's disease.

Hearing loss could accelerate the reduction of brain volume, study finds

Hearing loss in older adults might also cause accelerated gray matter atrophy, or a loss in brain volume, a new study shows. This indicates that devices such as hearing aids could be more important than previously thought.
