Scientists Just Uncovered How Menopause Rewires the Brain

Menopause reshapes the brain in surprising ways — but it may also reveal the brain’s remarkable ability to adapt.

During menopause, many women notice episodes of “brain fog,” which can include forgetfulness, difficulty focusing, and persistent mental tiredness. These challenges are often linked to shifting hormone levels. To better understand what is happening in the brain during this life stage, researchers reviewed previously published studies examining how structural brain changes relate to cognitive, emotional, and physical health outcomes. Their findings were presented at the 2025 Annual Meeting of The Menopause Society.

Enterovirus Encephalitis in People With Multiple Sclerosis on OcrelizumabInsights From a Multicenter Case Series

This multicenter case series highlights 5 cases of enterovirus encephalitis among people with MS receiving ocrelizumab, presenting with fever, encephalopathy, and gait changes, as well as myocarditis in 1 case.

ObjectivesAnti-CD20 therapies for multiple sclerosis (MS) are highly effective at preventing disease activity. Recognizing infectious complications of these therapies is essential. MethodsThree MS centers shared deidentified clinical data on persons with MS (pwMS) receiving ocrelizumab who developed enterovirus encephalitis.

Creating CAR-T Cells Using Current Alzheimer’s Antibodies

A team of researchers has biologically engineered T cells with currently available Alzheimer’s drugs in order to directly attack the characteristic amyloid plaques of Alzheimer’s disease.

Building on the current paradigm

Most Alzheimer’s treatments used in the clinic are-mabs, monoclonal antibodies that are designed to attack the amyloid beta plaques that accumulate in the brains of people with Alzheimer’s. However, while they have been found to have enough meaningful benefits in clinical trials to be approved by the FDA, they are not a cure, and some analyses question their effectiveness [1].

Lateral habenula and periaqueductal gray neurons signal reward prediction error and continuity of reward expectancy to drive reward-seeking behavior

Lee and Hikosaka show how animals overcome challenges and ultimately achieve goals. They find that LHb and PAG neurons encode prediction errors and the continuity of reward expectancy, with tonic PAG activity sustaining reward expectancy despite prediction errors.

A unified framework combining linear and 3D molecular features for robust drug-protein interaction prediction

Robust drug-protein interaction prediction tool.

The researchers develop PointDPI to predict drug-protein interactions (DPIs) by integrating linear and 3D molecular structures.

PointDPI preserves intermolecular relationships and predicts key regulatory sites, outperforming several state-of-the-art methods.

Four predicted drug-protein interactions (DPIs) are experimentally validated at both mRNA and protein levels, highlighting the therapeutic potential of adenosine in inflammatory diseases, ondansetron and etodolac in neurological diseases, and neuroprotective action for dopamine. sciencenewshighlights ScienceMission https://sciencemission.com/rug-protein-interaction

Sun et al. develop PointDPI to predict drug-protein interactions (DPIs) by integrating linear and 3D molecular structures. PointDPI preserves inter-molecular relationships and predicts key regulatory sites, outperforming several state-of-the-art methods.

Scientists discover new gatekeeper cell in the brain

VIB and Ghent University researchers have identified and characterized a previously unknown cellular barrier in the brain, which sheds new light on how the brain is protected from the rest of the body. In a study published in Nature Neuroscience, the scientists also reveal a new pathway by which the immune system can impact the brain.

Prof. Roosmarijn Vandenbroucke (VIB–UGent Center for Inflammation Research), said, “These findings reveal how vulnerable and protectable the brain is, opening new perspectives for more targeted interventions in brain disorders.”

The brain is protected from the rest of the body by multiple barriers that maintain a stable, tightly regulated environment and defend it against harmful substances and pathogens. The most well-known of these barriers is the blood-brain barrier, but another critical interface is the choroid plexus, a small structure found within the brain’s fluid-filled spaces, which produces cerebrospinal fluid.
