In an MRI study of 337 young people aged 8 to 18, autistic boys and autistic girls each showed their own cluster of brain structure differences compared with peers of the same sex.1 The boys’ pattern centered on a face-processing region and tracked with social and communication traits; the girls’ pattern centered on a memory …
Nearly 1 in 5 people with COPD in Lithuania had a recorded diagnosis of anxiety or depression, according to a nationwide study of 64,246 patients. Anxiety was far more common than depression, and most patients who received medication were prescribed benzodiazepines.1 Research Highlights 18.1% had a recorded diagnosis: 11,608 of 64,246 adults with COPD in …
A 2026 Environmental Science & Technology experiment found that wild guppies still reduced maze solve times with practice after 11-day exposure to environmentally motivated amitriptyline concentrations, but exposed males made 26.35% to 34.21% more navigation errors than control males.1 The result is a sex-specific accuracy signal, not a blanket claim that antidepressant pollution erased learning. …
A 2026 mouse study found that complete IL-6 deficiency worsened motor dysfunction and dopaminergic injury in MPTP and alpha-synuclein A53T Parkinson’s disease models, with earlier and broader vulnerability in female knockout mice.1 The result cuts against a simple “less inflammation is always better” frame: recombinant IL-6 partly improved MPTP-induced motor dysfunction and striatal dopaminergic terminal …
A 2026 multicenter Italian cohort followed 216 early Parkinson’s disease patients for 24 months after levodopa initiation and found sex/gender differences in non-motor symptom burden.1 Women had higher anxiety, pain, mobility, and emotional-well-being burden, while men had higher hypersexuality. Research Highlights Longitudinal sample: The study followed 216 early levodopa-naive Parkinson patients, including 139 men and …
A 2026 Drosophila Parkinson’s model exposed male and female flies to 500 μM rotenone. By 60 days, male flies had worse survival/climbing than female flies; the paper is a vulnerability screen, not evidence that the same genes are ready human biomarkers.1 Research Highlights 500 μM rotenone split male and female flies: Iyer et al. used …
A 2026 ECG analysis involving 269 healthy young adults found that sex differences in resting heart-rate dynamics appeared in very short 2-5 second fluctuations, not in the usual 5-minute heart rate variability averages. The short-window similarity graph metric predicted male sex with an odds ratio of 2.78 (95% CI 1.32-5.86), while conventional lnRMSSD, lnHF-HRV, and …
