Astronauts aboard the International Space Station, for example, have experienced altered vision and increased pressure inside their heads, symptoms termed as Read the rest of this entry »

Next: Brain scans to identify children at high risk of developing multiple sclerosis (MS) before symptoms appear

White arrows indicate abnormalities on MRI brain scans in children with no symptoms of multiple sclerosis.


MS risk in children spotted with MRI brain scans (Yale News):

“By the time multiple sclerosis (MS) is diagnosed in children, it may be difficult to prevent the disabilities and relapses that come with the disease. In a new Yale School of Medicine study, researchers examined MRI brain scans to identify children at high risk of developing MS before symptoms appear, which Read the rest of this entry »

The Mediterranean Diet seen to substantially reduce brain shrinkage among older adults



Less shrinkage: This is your aging brain on the Mediterranean diet (Los Angeles Times):

“The aging brain is a shrinking brain, and a shrinking brain is, generally speaking, a brain whose performance and reaction time are declining: That is a harsh reality of growing older.

But new research shows that brain shrinkage is less pronounced in older folks whose diets Read the rest of this entry »
