Rapid Tissue‐CSF Water Exchange in the Human Brain Revealed by Magnetization Transfer Indirect Spin Labeling

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 6, Page 3270-3283, June 2026.
ABSTRACT Purpose To apply the Magnetization Transfer Indirect Spin Labeling (MISL) MRI technique for quantifying tissue‐CSF water exchange in the human brain, and to investigate its utility in (1) evaluating tissue‐CSF water exchange within perivascular spaces (PVS), and (2) characterizing altered water exchange dynamics in pathologic conditions ...

Effects of Histamine H3 Receptor Antagonist/Inverse Agonist Pitolisant on Temporal Prediction, Spatial Switching, and Spontaneous Locomotion in Mice

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
The histamine H3 receptor antagonist/inverse agonist pitolisant did not affect temporal prediction and spatial switching. ABSTRACT Histamine receptors contribute to a wide range of brain functions, including arousal, motivation, attention, and memory, but their causal involvement in switching behavior remains insufficiently understood.

Japanese Cohort Study Identifies an Association Between the Serotonin Transporter–Linked Polymorphic Region and Suicide Death

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
The odds ratios and corresponding 95% confidence intervals for suicide death by 5‐HTTLPR S allele, in main and subgroup analyses. Statistical significance is indicated. ABSTRACT Introduction More than 720 000 individuals die by suicide annually worldwide, making it a major public health concern and a leading cause of death among young people ...

Dimensional association between ADHD traits and gray matter volume in young adults: A voxel‐based morphometry study

open access: yesPsychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
This study examined the association between attention‐deficit/hyperactivity disorder (ADHD) traits and gray matter volume (GMV) in 534 healthy young adults. Higher Hyperactivity/Restlessness scores were associated with greater GMV in the right dorsolateral prefrontal cortex (DLPFC), a region implicated in executive control and behavioral regulation. No

Combined Inhibition of TRPM4/NMDA Receptor Complex and Extrasynaptic NMDA Receptors Is Candidate Therapeutic Target for Suppression of Epileptic Seizures and Improvement of Cognitive Impairments

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Cognitive impairments are important therapeutic targets in epilepsy medication; however, effective pharmacological treatments for epilepsy patients with comorbid cognitive impairment have not been established. Effects of chronic administration of MK‐801 (noncompetitive NMDA receptor inhibitor), memantine (low‐affinity extrasynaptic‐NMDA ...

Hippocampal subfield differences in people with and without recreational ketamine use: Insights from multi‐modal neuroimaging

open access: yesAddiction, Volume 121, Issue 6, Page 1541-1556, June 2026.
Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...

Psychosocial Factors Mediate the Relationship Between Olfactory Function and Cognitive Frailty in Older Adults: A Structural Equation Modelling

open access: yesAustralasian Journal on Ageing, Volume 45, Issue 2, June 2026.
ABSTRACT Objective With the trend of population ageing, cognitive frailty in older adults is an increasingly pressing public health issue. Identifying early‐stage risk factors has become a key priority for researchers with the goal of preventing disability.

Abnormal amyloid PET usually represents intermediate/high Alzheimer's disease neuropathologic change

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Alzheimer's disease neuropathologic change (ADNC) classification identifies not/low and intermediate/high levels of neuropathology. Our goal was to assess how frequently a positive amyloid positron emission tomography (PET) scan indicates not/low ADNC and whether this autopsy finding can occur >10 years after a positive amyloid ...

Tau Pathology in Alzheimer's Disease Uniquely Affects Sulcal Depths

open access: yesAnnals of Neurology, Volume 99, Issue 5, Page 1343-1353, May 2026.
Objective Though it is widely known that tau deposition affects brain structure, the precise localization of these effects is poorly understood, especially in relation to gyral and sulcal anatomy. We investigated whether tau pathology in Alzheimer's disease (AD) preferentially affects sulci, and particularly sulcal depths.

Functional Connectivity During Social Reward Processing in Autistic and Neurotypical Adolescents

open access: yesBrain and Behavior, Volume 16, Issue 5, May 2026.
Heightened task‐evoked functional connectivity was observed in autistic youth between the amygdala and the posterior superior temporal sulcus (pSTS), core regions of the social reward circuitry, on receipt of a social‐interactive reward. The strength of connectivity was negatively correlated with enjoyment of social interaction.
