New research advances understanding of epilepsy and Alzheimer's

New research is providing fresh insights into the mechanisms of neurodegenerative and neurological disorders. Researchers from Berkeley have discovered that in tuberous sclerosis complex (TSC), hyperreactive astrocytes—rather than overactive neurons—act as the primary drivers of disease-causing lesions. Using 3D brain organoids derived from stem cells, the study identified an inflammatory profile in these astrocytes that overlaps with patterns seen in neurodegenerative diseases like Alzheimer's. This suggests a potential new therapeutic approach focused on calming reactive glial cells instead of systemic mTOR inhibition.

In a separate development, researchers in Italy are testing a nasal spray that may offer a breakthrough in treating Alzheimer's disease. The spray utilizes extracellular vesicles derived from the amniotic membrane of the placenta. Initial tests indicate that these vesicles can reach the hippocampus, reducing neuroinflammation and protecting memory and neuronal functions. This method aims to deliver biological signals directly to the brain to combat cognitive decline.
