Mar. 5, 2025 — Scientists used positron emission tomography (PET) with edaravone, a drug used to treat ALS, to detect oxidative stress, which leads to brain damage, offering a clear path to ...

Not the Same. In amyloid-negative people (left) few tangles accumulate over a decade. In amyloid-positives (right), tangles grow faster in women (red) than men (blue). [Courtesy of Gillian Coughlan, ...

Older women who take menopausal hormone therapy may be at a higher risk of Alzheimer's. A study published in Science Advances on Wednesday found faster accumulation of tau proteins – implicated in ...

The cerebral cortex in humans is folded into gyri and consists of six horizontal layers of neurons, with distinct connections among the layers and neuronal subtypes of cells. Neural speech ...

Inclusions of pathogenic deposits containing TAR DNA-binding protein 43 (TDP-43) are evident in the brain and spinal cord of patients that present across a spectrum of neurodegenerative diseases. For ...

Cerebral amyloid angiopathy (CAA) is driven by vascular Aβ (amyloid‐beta) deposition, which can be detected as reduced Aβ species in cerebrospinal fluid (CSF). We sought to identify relationships ...

Neuropsychiatrists explain the science behind love, identifying stages like lust, attraction, and attachment. Hormones and brain regions play key roles, with cortisol inducing stress, dopamine driving ...

The terms "left-brained" and "right-brained" refer to the two hemispheres of the brain's cerebrum. The left hemisphere generally focuses more on speech and language, while the right hemisphere manages ...

The study revealed distinct brain ageing patterns based on sex and age. In healthy females, ageing was most prominent in the right precentral gyrus, postcentral gyri, and superior parietal lobules ...

Researchers developed a groundbreaking method to track brain ageing pace using deep learning and MRI scans, providing insights into cognitive decline.
