Sense of smell may hold clues to Lewy body pathology: new evidence emerges

Researchers evaluated the impact of Lewy body (LB) positivity (+) on clinical outcomes such as cognition and smell among cognitively.

New biomarker could track progression of Alzheimer's disease

Two pathologies drive the progression of Alzheimer's disease. Early on, amyloid beta plaques lead the way, but around the time cognitive symptoms arise, tau tangles take over as the driving force and cognition steadily declines.

PET scan not effective in diagnosing chronic traumatic encephalopathy in former NFL players, study finds

A new study showed that positron emission tomography (PET) with the radiotracer (18F)-Flortaucipir (FTP) to detect hyperphosphorylated Tau (p-tau) may not be appropriate for diagnosing chronic traumatic encephalopathy (CTE) neuropathologic changes in former professional American-style football players.

Gut microbiota holds clues to predicting Alzheimer's risk

Gut microbiome alterations in preclinical Alzheimer's disease (AD) were investigated, revealing distinct taxonomic composition and potential markers of AD risk. These findings contribute to understanding AD pathology and offer insights into gut-derived markers for AD.

Connecting the inflammatory dots: Obesity, depression, and Alzheimer's linked by neuroinflammation

Obesity-induced neuroinflammation significantly contributes to the pathophysiology of depression and Alzheimer's disease. Targeting midlife stage for intervention is crucial to potentially prevent Alzheimer's pathology.

Sleep-disordered breathing in cognitively unimpaired amyloid-positive individuals may exacerbate neurodegeneration in medial temporal lobe subregions

A new study investigated the link between SDB severity and the volume of medial temporal lobe (MTL) substructures. In addition, it also evaluated the association between SDB and MTL subregions volumes with episodic memory performance.

Former anabolic steroid users more likely to develop heart disease

Anabolic steroids not only can cause serious side effects during use, such as heart failure and depression, but can continue being harmful years after stopping, according to two studies presented at the 25th European Congress of Endocrinology in Istanbul.

Military personnel exposed to explosions show abnormal amyloid accumulation in the brain

New research finds that the brains of otherwise healthy military personnel who are exposed to explosions show an abnormal brain accumulation of amyloid-beta protein - a protein that plays a role in the development of Alzheimer's disease.
