 The Pillars of Precision Alzheimer’s Diagnostics
The current AD diagnostic revolution relies on accessible blood-based biomarkers to bridge the detection gap. However, valid clinical implementation hinges on three pillars: pre-analytical rigor to ensure biomarker stability, longitudinal tracking to map disease progression, and comprehensive metadata to address health disparities

|  | | | | |  Cocoa looks promising for mood, but the brain benefits come with a catch A review of clinical and preclinical studies suggests cocoa polyphenols may support mood, neuroplasticity, cerebral blood flow, and gut-brain signaling through pathways involving BDNF/CREB, inflammation, and oxidative stress. | |  | | | | |  Psilocybin may make the brain more organized than scientists expected In 62 adults, researchers combined fMRI, EEG and machine learning to examine how psilocybin reshapes brain activity during rest, meditation, music and movie viewing. They found that context-sensitive neural organization tracked the intensity and quality of psychedelic experiences and was associated with next-day mindset change. | |

| | | |  A Cell perspective argues that neurodegeneration can emerge from disrupted communication between neural and immune networks, with peripheral immunity, microglia, and gene-regulatory programs all shaping disease processes. The authors propose that restoring immune homeostasis and recalibrating neuroimmune circuits could create new therapeutic and diagnostic opportunities, while emphasizing that many mechanisms remain unresolved in humans. | | | | |  Overreactions to ordinary sensory stimuli - a scratchy shirt tag, a roaring vacuum cleaner, an unfamiliar smell - are commonly associated with autism. | | | | |  Use of hormone therapy later in life was associated with lower risk of developing dementia, according to a study published August 12, 2026, in Neurology, the medical journal of the American Academy of Neurology. | | | | |  In a new paper appearing Aug. 18 in Nature Communications, Princeton University researchers show how music produces distinct patterns in the regions of the brain associated with imagination and meaning, similar to those prompted by spoken narratives. | | | | |  A urinary tract infection that follows a moderate brain injury can worsen cognitive problems caused by the injury, new research in mice shows. | | | | |  Researchers at The Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells. | | | | |  Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals how astrocytes, brain cells known for supporting neurons and their functions, can directly regulate brain circuits involved in memory consolidation. | |
