A study published in Cerebral Cortex finds that aging brains blend memories together rather than simply forgetting them, as older adults show broader, less precise recall patterns linked to hippocampal activity during memory tasks.
Scientists at Texas A&M have developed a nasal spray using extracellular vesicles carrying microRNAs that reverses brain inflammation and restores memory in aged brains, with results lasting months. The therapy could potentially treat Alzheimer's and other neurodegenerative conditions.
