TL;DR: A 2026 preprint on medRxiv found that in-person cognitive behavioral therapy for insomnia and several shorter behavioral versions were linked with higher post-treatment insomnia remission than sleep hygiene or other control conditions, but the evidence was strongest for full CBT-I. Key Findings 77 randomized trials: The network meta-analysis included 77 RCTs with 5,731 adults …
TL;DR: A 2026 Nature Communications study found that chronic tumor necrosis factor alpha (TNF-alpha), an inflammatory cytokine, pushed human hippocampal progenitor cells toward type I interferon activity, lower neuroblast formation, and CXCR3-dependent T-cell recruitment. Key Findings 0.1-1 ng/ml TNF-alpha: The key experiments used chronic low-dose TNF-alpha exposures that the researchers considered biologically relevant for inflammatory …
TL;DR: A 2026 study in the European Journal of Nuclear Medicine and Molecular Imaging reported that adolescent bipolar II depression showed lower thalamic structural-functional connectivity coupling and glucose metabolism than adolescent major depressive disorder in a small exploratory positron emission tomography/MRI (PET/MRI) sample. Key Findings 28 adolescents scanned: The study compared 14 adolescents with bipolar …
TL;DR: A 2026 systematic review and meta-analysis in Journal of Medical Internet Research found that care robots showed a low-certainty reduction in neuropsychiatric symptoms, but six other pooled outcome domains did not reach statistical significance. Key Findings 34 randomized trials: The review included 34 randomized controlled studies across 17 countries, with 2,476 participants. 20 meta-analyzed …
TL;DR: A 2026 preprint in medRxiv reported that frailty and medical comorbidity predicted short-term outcomes more clearly than psychiatric history among older adults evaluated by consultation-liaison psychiatry teams in Spanish general hospitals. Key Findings 465 older inpatients: The prospective OLD-3 cohort included adults aged 65 years and older referred to consultation-liaison psychiatry in 10 Spanish …
TL;DR: A 2026 narrative review in International Journal of General Medicine argued that apathy in Alzheimer’s disease is tied to damage across motivation circuits, including the anterior cingulate cortex, orbitofrontal cortex, striatum, locus coeruleus, and large-scale brain networks. Key Findings Apathy was framed as its own syndrome: The review separates reduced goal-directed behavior from depression, …
TL;DR: A 2026 study in eLife found that infants’ brains responded more strongly to structured children’s music than shuffled music by 3 months, while clearer music-linked movement patterns appeared mainly by 12 months. Key Findings 79 infants tested: Researchers recorded electroencephalography (EEG), a scalp measure of brain electrical activity, and video-based body movement in 3 …
TL;DR: A 2026 narrative review in Clinical Drug Investigation argued that desvenlafaxine, a serotonin-noradrenaline reuptake inhibitor (SNRI), may be a first-line major depressive disorder option for selected patients, especially when fatigue, cognitive complaints, polypharmacy, or tolerability concerns shape the treatment choice. Key Findings Review plus consensus: The source combined a PubMed-based narrative review with a …
TL;DR: A 2026 preprint in medRxiv found that stroke survivors doing motor imagery showed changing brain-heart coupling across rehabilitation sessions, especially between cardiac sympathetic activity and electroencephalography (EEG) beta-band network clustering. Key Findings 15 stroke survivors: Researchers analyzed two cohorts with upper- or lower-limb motor impairment after stroke. 2 motor-imagery protocols: Dataset 1 used gait …
TL;DR: A 2026 preprint posted on medRxiv reported that resting-state electroencephalography (EEG) neural slowing after stroke tracked secondary thalamic degeneration measured on structural MRI, even though the sampled patients did not have direct thalamic lesions. Key Findings 25 stroke patients: Researchers studied adults at least 3 months after unilateral supratentorial stroke and compared their resting-state …
