 Brain with an air-pocket lesion in a rare case report of an elderly man
 
Brain with an air-pocket lesion in a rare case report of an elderly manAn 84 year old was complaining of repeatedly losing his balance and falling over. He visited his primary physician in Northern Ireland from where he was referred to the emergency room. On MRI, the team of doctors found a 3½-inch pocket of air in his brain. This has never been reported before in any case and thus the detailed report titled, “The man that lost (part of) his mind,” was published in the journal BMJ Case Reports.

High-resolution fMRI provides clues about age-related memory differencesAs we get older, it's not uncommon to experience "senior moments," in which we forget where we parked our car or call our children by the wrong names. And we may wonder: Are these memory lapses a normal part of aging, or do they signal the early stages of a severe disorder such as Alzheimer's disease? Currently, there's no good way to tell.
