Neuropsychiatric Genetic Risk Mapped Fluid and Crystallized Cognition

July 12, 2026 by BrainASAP

TL;DR: A 2026 study in Nature Communications found that neuropsychiatric disorder risk did not map onto cognition as one general trait. Schizophrenia, bipolar disorder, ADHD, autism, and Alzheimer’s disease showed different genetic links with reaction time, fluid reasoning, crystallized knowledge, and noncognitive educational skills. Key Findings 439,000-person GWAS scale: The crystallized-knowledge genome-wide association study had …

Systematic Review Identified Limited Medication Signals for Online Addictions

July 12, 2026 by BrainASAP

TL;DR: A 2026 systematic review in Future Science OA found early medication evidence for online behavioral addictions, but the 20 included studies were mostly small, male-heavy, and short-term. Key Findings Medication evidence stayed early: The review found small, mixed pharmacotherapy signals across 20 online behavioral addiction studies. Clinical groups stayed small: The 1,016 total participants …

GLP-1RAs Linked to Lower Heart Failure Risk in Obstructive Sleep Apnea

July 11, 2026 by BrainASAP

TL;DR: A 2026 real-world study in Journal of Clinical Sleep Medicine found that glucagon-like peptide-1 receptor agonist use was associated with lower 3-year cardiovascular-event risk in adults with obesity and obstructive sleep apnea. Key Findings 18,523 matched pairs: Propensity matching compared GLP-1 receptor agonist users with similar non-users who had obesity and obstructive sleep apnea. …

EMS Plus Low-Intensity Resistance Exercise Improved Inhibitory Control

July 11, 2026 by BrainASAP

TL;DR: A 2026 crossover study in Clinical Physiology and Functional Imaging found that adding electrical muscle stimulation to low-intensity resistance exercise improved inhibitory control in young men, while stimulation alone showed a delayed 15-minute benefit. Key Findings 17 young men: Participants completed low-intensity resistance exercise, electrical muscle stimulation alone, and combined low-intensity exercise plus stimulation …

COMBAT-ICU Cognitive Training Reduced PICS Severity in Pilot Trial

July 11, 2026 by BrainASAP

TL;DR: A 2026 pilot randomized trial in Nursing in Critical Care found that an 8-week home-based program combining exercise with computerized cognitive training was feasible in 36 ICU survivors and produced larger reductions in patient-reported post-intensive care syndrome severity than attention control, while exploratory cognitive and quality-of-life effect sizes generally favored the combined program over …

Depression Nanomedicine Needs More Than Blood-Brain Barrier Delivery

July 11, 2026 by BrainASAP

TL;DR: A 2026 review in International Journal of Nanomedicine argued that depression nanomedicine should move beyond blood-brain-barrier delivery alone and be judged by target engagement, neuroimmune-barrier-plasticity effects, safety, manufacturability, and patient stratification. Key Findings Mechanism-centered review: The paper organized depression nanomedicine around neuroinflammation, blood-brain-barrier dysfunction, oxidative stress, and impaired neuroplasticity. 3 strategy groups: The review …

FP-CIT SPECT Ratios Improved Parkinsonism Classification

July 11, 2026 by BrainASAP

TL;DR: A 2026 study in European Journal of Nuclear Medicine and Molecular Imaging found that semiquantitative [123I]FP-CIT SPECT metrics, especially caudate-to-putamen and sensorimotor-to-limbic ratios, helped distinguish Parkinson’s disease from atypical parkinsonian syndromes, while a random forest classifier remained more useful as decision support than as a standalone diagnosis. Key Findings 706-patient cohort: The study included …

Quetiapine Linked to Better Working Memory in Schizophrenia

July 11, 2026 by BrainASAP

TL;DR: A 2026 study in European Archives of Psychiatry and Clinical Neuroscience linked sustained quetiapine treatment with better high-working-memory cognitive performance in schizophrenia spectrum disorder, but the genetic tests did not support the proposed remyelination-moderation mechanism. Key Findings 166 matched pairs: The extended PsyCourse analysis included 166 quetiapine-treated schizophrenia-spectrum patients and 166 age- and sex-matched …

Lecanemab Linked to Lower Neuropsychiatric Symptoms in Alzheimer’s

July 11, 2026 by BrainASAP

TL;DR: A 2026 real-world cohort study in The Journal of Prevention of Alzheimer’s Disease found that lecanemab-treated Alzheimer’s patients had lower Neuropsychiatric Inventory scores over follow-up, and 6-month symptom reductions were associated with regional amyloid-beta positron emission tomography (PET) clearance. Key Findings 144 treated patients: The cohort included people with Alzheimer’s-related mild cognitive impairment or …

DLPFC rTMS Improved Dual-Task Walking After Subacute Stroke

July 11, 2026 by BrainASAP

TL;DR: A 2026 randomized trial in Physiotherapy Research International found that adding active 5 Hz repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex to dual-task stroke rehabilitation produced larger gains in Timed Up-and-Go performance, balance confidence, and cognitive screening than sham stimulation plus the same training. Key Findings Small randomized trial: The study …
