Prevalence of age-related atrophy in gray matter may be overestimated in healthy aging brain

The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain.

Omega-3 fatty acids prevent and slow age-related macular degeneration

Researchers are seeing more benefits of omega-3 fatty acids (omega-3s), such as their ability to help prevent and slow age-related macular degeneration (AMD), an eye disease that is the leading cause of severe vision loss in older people.

UCF research team develops miniature diagnostic tool kit to diagnose dementia

With the risk of developing dementia growing at an alarming pace, a University of Central Florida research team is working with the Boston University School of Medicine to develop a miniature diagnostic toolkit in the hopes of stimulating earlier detection and treatment.

Blood test to identify MCI patients at risk of Alzheimer's disease

Elderly people exhibiting memory disturbances that do not affect their normal, daily life suffer from a condition called "mild cognitive impairment" (MCI). Some MCI patients go on to develop Alzheimer's disease within a few years, whereas other cases remain stable, exhibiting only benign senile forgetfulness. It is crucial to develop simple, blood-based tests enabling early identification of these patients that will progress in order to begin therapy as soon as possible, potentially delaying the onset of dementia.

Neurodegenerative disorders second-leading cause of early-onset dementia

Neurodegenerative disorders called frontotemporal dementias (FTD) are the second-leading cause of early-onset dementia in persons under age 65 and can emerge sometimes as early as age 20.
