Structural covariance networks (SCNs) may be an important indicator of diminished cognitive functioning in older persons, suggested a new study.
Brain Scan During Stress may Detect Shrinking of the Brain Linked to Memory Loss
A brain scan conducted while someone is going through stress may detect shrinking in a part of the brain that can eventually lead to memory loss, suggests a study.

‘The micro-scale blood vessel alterations in the brain are correlated to impaired cognitive functioning with advancing age.’
Jessica Foster-Dingley, Jeroen van der Grond from Leiden
University Medical Center and Leiden University, the Netherlands and
CAPRI-University of Antwerp, Belgium, analyzed the magnetic resonance
imaging (MRI) scans of study participants aged 75-96 years who had mild
loss in cognitive function. The researchers assessed the volume of white
matter hyperintensities, microbleeds, and other vascular changes
associated with small vessel disease. They compared this to the
expression of SCNs, age, memory loss, and psychomotor speed. "Scientific consensus is building that age related cognitive decline is connected to maladaptive changes in the brain's small blood vessels," says Christopher Pawela, Co-Editor-in-Chief of Brain Connectivity and Assistant Professor, Medical College of Wisconsin. "Leiden University researchers have performed an elegant study using magnetic resonance imaging (MRI) to demonstrate that these micro-scale blood vessel alterations are related to decreased detection of certain imaging brain networks and, furthermore, that decreased detection of these brain networks is correlated to impaired cognitive functioning using standard behavioral testing methods."

Dementia Progression Halted With Drug-free MAKS Therapy
Dementia has different causes and although its progression can be fast or slow, it is always degenerative. MAKS therapy can control the decline, research confirms.
