Brain Age MRI Mapped Stroke Recovery in 501 Patients TL;DR: A Lancet Digital Health ENIGMA study found that larger stroke lesions made the damaged hemisphere look biologically older, while severe motor impairment was linked to younger-appearing contralesional networks, likely reflecting compensation. Key Findings 501 chronic stroke survivors: The ENIGMA Stroke Recovery Working Group dataset included …
Blood GFAP Started Mirroring the Brain Only After the BBB Leaked TL;DR: Blood biomarkers mostly failed to mirror the brain while the blood-brain barrier stayed intact; once the barrier leaked, glial fibrillary acidic protein (GFAP), an astrocyte injury protein, and inflammatory signals started lining up across blood and cerebrospinal fluid (CSF), the fluid surrounding the …
ECT Looks Safer in the Long Run Than Its Reputation TL;DR: A British Journal of Psychiatry review argues that modern population-level studies do not support a long-term increase in dementia or major cardiovascular risk after electroconvulsive therapy and instead point toward lower suicide mortality and all-cause mortality in the patients who receive it. Key Findings …
TL;DR: A CAR-style therapy aimed at astrocytes turned brain support cells into amyloid cleaners, preventing plaque development and cutting existing plaque burden by about half in mice. Key Findings Plaque-free prevention arm: Young mice treated before plaques formed were reported plaque-free at nearly 6 months, when untreated Alzheimer-model mice are normally saturated. 50% plaque reduction: …
Body Roundness Index Flagged Depression Risk in Dementia TL;DR: Body roundness index, not BMI, flagged a dementia subgroup with more than threefold higher odds of depressive symptoms. Key Findings Highest BRI tripled odds: Among people with dementia, those in the highest body-roundness quartile had more than threefold greater odds of depressive symptoms than those in …
Esketamine Lost the Cost-Effectiveness Race in Hong Kong TL;DR: A 5-year Hong Kong model found esketamine plus an antidepressant bought only a small quality-adjusted survival gain at US$29,061 per patient, leaving it behind cheaper third-line options like combination therapy. Key Findings Seven third-line strategies modeled: A Markov cohort model followed adults with treatment-resistant depression in …
Hearing Aids Beat PSAPs Where Real-World Listening Gets Hard TL;DR: Hearing aids beat personal sound amplifiers where listening gets hardest: high-frequency sound, speech in noise, and daily user satisfaction. Key Findings Hearing aids won the crossover test: Adults with sensorineural hearing loss used either a hearing aid or a PSAP for 3 months, then switched …
How Focused Ultrasound Reprogrammed Microglia in Alzheimer’s Rats TL;DR: In TgF344-AD rats, repeated low-intensity focused ultrasound triggered a short-lived inflammatory response, then left behind a more durable microglial metabolic shift in early disease without clearly improving Alzheimer’s pathology on its own. Key Findings 450 kPa across a 12 x 6 mm target: The team skull-corrected …
Ethanolamine Looked Like a Depression Biomarker and Treatment Target TL;DR: In a 380-person cerebrospinal fluid dataset, patients with active major depression had lower ethanolamine levels than controls, those levels rose after electroconvulsive therapy, and parallel rat experiments suggested the molecule may be more than just a marker. Key Findings 380-person cerebrospinal fluid (CSF), the fluid …
Brainstem Expiratory Neurons Drove Hypertension TL;DR: A brainstem region involved in forceful exhalation also appears to drive blood-vessel constriction, making it a possible target for some forms of neurogenic hypertension. Key Findings A forced-exhalation region joined the pressure mechanism: The lateral parafacial region, normally recruited for strong expiration, was active under hypertensive conditions. Blood-vessel nerves …
