PTP1B Inhibition Boosted Amyloid Clearance in Alzheimer’s Mice

In APP/PS1 Alzheimer's model mice, deleting PTP1B or treating with the allosteric inhibitor DPM-1003 improved memory behavior, lowered amyloid burden, and pushed microglia toward SYK-driven clearance — a plausible mechanism, not a human treatment result yet.1 Research Highlights PTP1B loss improved behavior in APP/PS1 mice. Genetic deletion and DPM-1003 treatment improved novel object recognition and …

Cocaine-Alcohol Relapse Shifts Prelimbic-Accumbens Circuit

Cocaine relapse circuitry looks different when alcohol is part of the history. In a rat model, inhibiting prelimbic cortex neurons projecting to the nucleus accumbens core blocked cue-triggered cocaine seeking after cocaine alone, but failed after sequential cocaine-alcohol polysubstance use.1 Research Highlights PL-NAc inhibition split by drug history: in a 4-group DREADD experiment, inhibiting the …

Psychopathy, Empathy, and Cortical Structure in 804 Incarcerated Men

Psychopathy is not a simple “low empathy equals abnormal brain scan” story. In 804 incarcerated men, psychopathy factors tracked empathic concern, perspective taking, cortical thickness, surface area, and cortical organization—but self-reported empathy scores did not map cleanly onto cortical structure.1 Research Highlights The sample was unusually large for forensic MRI. Radecki et al. analyzed 804 …

Extra-Virgin Olive Oil Raised Brain Connectivity in a 9-Person Pilot

MHD featured image for extra-virgin olive oil and brain connectivity.

A 9-person randomized crossover neuroimaging substudy found that high-polyphenol extra-virgin olive oil increased occipital resting-state functional connectivity compared with regular olive oil, beta = 0.20, 95% CI 0.03 to 0.37, p = 0.016.1 The result is a measurable brain-signal finding, but the clinical claim stays small: connectivity changed, cognition was not the endpoint. Research Highlights …

Multiple Sclerosis Personalized Therapy: 70% Delphi Consensus

MHD featured image for personalized multiple sclerosis therapy consensus.

An Italian multiple sclerosis Delphi panel reached consensus on 116 of 166 votes, meaning 70% of expert votes aligned and 30% still exposed disagreement about personalized therapy, patient involvement, and treatment sequencing.1 The result supports individualized MS treatment planning, but it is consensus evidence rather than proof that one disease-modifying therapy fits every high-risk patient. …

Hypoglossal Nerve Stimulation Improved Sleep Symptoms More Than Cognition

MHD featured image for hypoglossal nerve stimulation, sleep apnea symptoms, and cognition.

A 2026 CARDIOSA-12 secondary analysis found that active hypoglossal nerve stimulation improved sleepiness, insomnia, snoring, and sleep-related function, but objective cognitive test performance mostly did not improve compared with partially therapeutic stimulation.1 Symptom relief and measurable cognitive recovery answer separate clinical questions in treated obstructive sleep apnea. Research Highlights Subjective outcomes improved: active HGNS improved …

Cancer Survivor Neuropathic Pain: Duloxetine and Exercise Signals

MHD featured image for cancer survivor neuropathic pain treatment evidence.

A 2026 scoping review screened 956 systematic reviews/guidelines and 604 original studies on cancer-survivor neuropathic pain, but only 11 pharmacological, 2 psychological, and 3 exercise studies were eligible.1 The practical signal is narrow: duloxetine and some exercise programs have the clearest support, while psychological and interdisciplinary evidence is still too thin for confident treatment ranking. …
