Glucose and Alzheimer’s

One of the earliest signs of Alzheimer’s is a decline in glucose levels in the brain.  Yet whether or not it’s a cause or consequence of neurological dysfunction has been debated.  However, new research at the Lewis Katz School of Medicine at Temple University unequivocally reveals that a lack of glucose triggers cognitive decline, rather than being caused by cognitive decline.   In recent years, advances in imaging techniques, particularly positron emission tomography (PET), have allowed researchers to look for subtle changes in the brains of patients with different...

CJD and Alzheimer’s?

According to new research, the brains of Creutzfeldt-Jakob disease (CJD) victims show evidence of Alzheimer’s pathology.  However, neuroscientists have dismissed concerns that people can “catch” Alzheimer’s by becoming infected with the “seeds” of the condition through surgery with contaminated instruments or blood transfusions.  The study, published in Nature last week, reported autopsy results from the brains of eight people between 36 and 51 years old who died of CJD after receiving contaminated growth hormone injections.  In four subjects, there was evidence of...
