Semaglutide Reduced Cocaine Choice in Rat Study

Semaglutide is not close to being an approved cocaine-use-disorder medication, but a 2026 rat study gives the idea a more demanding preclinical test than ordinary self-administration experiments. After 5 days of treatment, rats shifted away from cocaine choice without losing total operant responding, which separates the result from a broad appetite-suppression artifact. Research Highlights Semaglutide …

ALS CSF Proteomics Found 399 Candidate Proteins and a 5-Protein Panel

MHD featured image for ALS CSF proteomics and biomarker panels.

A 2026 cerebrospinal-fluid proteomics preprint involving 87 amyotrophic lateral sclerosis (ALS) patients, 89 healthy controls, and 61 neurological controls reported 399 ALS candidate proteins, complement markers that tracked disease stage, and a 5-protein panel that classified ALS vs. healthy controls with ROC AUC 0.95 after the best-known neurodegeneration markers were removed.1 Research Highlights CSF proteomics …

Adult ADHD Linked to Lower SIRT-1/Nrf-2/HO-1 Antioxidant Defenses

MHD featured image for adult ADHD, SIRT-1, Nrf-2, HO-1, and antioxidant-defense biomarkers.

A 2026 case-control study found that treatment-naive adults with attention-deficit/hyperactivity disorder (ADHD) had much lower serum SIRT-1, Nrf-2, and HO-1 than matched controls, while TNF-α did not differ. The pattern points more toward impaired antioxidant-defense regulation than a simple broad-inflammation story. Research Highlights Antioxidant-defense markers were lower: adults with ADHD had lower SIRT-1 (9.36 vs. …

Rare OCD Variants in NPY5R, DLGAP1, and MAPK8IP3 Segregate in Families

Editorial card for rare OCD variants in NPY5R, DLGAP1, and MAPK8IP3 across multiplex families.

A 2026 whole-genome sequencing preprint found rare variant signals in 2 multiplex obsessive-compulsive disorder (OCD) families: an NPY5R missense variant in 10 of 15 affected people in 1 pedigree, plus DLGAP1 and MAPK8IP3 signals that tracked all 3 sequenced cases in a branch of a second pedigree.1 The finding is a candidate-gene result, not a …

ALS Entropy Analysis Finds 5-Month Signal Hidden by ALSFRS Scores

MHD featured image for ALS trial endpoints, Shannon entropy, and ALSFRS domain trajectories.

A 2026 PRO-ACT analysis of amyotrophic lateral sclerosis (ALS) trial data found a signal that ordinary ALSFRS total-score slopes cannot even express: Shannon entropy trajectories diverged between pooled active and placebo arms, including a 5-month delay in peak Fine Motor distributional spread for active-arm patients.1 Research Highlights Entropy found an endpoint-level signal: Rodriguez analyzed 7,512 …
