Epilepsy‐Related Psychosis in Drug‐Resistant Epilepsy With Nonconvulsive Status Epilepticus and Difficult Antipsychotic Titration: A Case Report

Neuropsychopharmacology Reports, Volume 46, Issue 3, September 2026.
Electroclinical findings supported diazepam‐responsive nonconvulsive status epilepticus (NCSE) in an older patient with drug‐resistant epilepsy and psychosis. After phenytoin treatment, continuous EEG helped monitor recurrence. Later symptoms were most consistent with interictal psychosis with a possible alternative psychosis component, emphasizing ...

Increased Binding of [18F]Nifene, a PET Imaging Probe for α4β2* Nicotinic Acetylcholinergic Receptors in Hippocampus–Subiculum of Postmortem Human Parkinson's Disease Brain

Synapse, Volume 80, Issue 5, September 2026.
[18F]Nifene, a PET imaging probe for α4β2* nicotinic acetylcholine receptors, was used to discretely measure changes in hippocampus (HP) and subiculum (SUB) of postmortem Parkinson's disease (PD) cases compared to cognitively normal (CN) cases. Significant increased [18F]nifene binding in PD was observed.

Scanner‐agnostic artificial intelligence approach for fast bone scintigraphy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Purpose Current bone scintigraphy protocols often demand full‐count, 10–15 min scans to preserve image quality, and existing deep‐learning (DL) denoisers typically need to be retrained or retuned for each camera manufacturer. We introduce a scanner‐agnostic adaptive‐diffusion U‐Net designed to reconstruct diagnostic‐grade images from half‐time

An interpretable radiomics–deep learning nomogram from whole‐body bone scintigraphy for MDP‐avid bone metastasis prediction in NSCLC

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Whole‐body bone scintigraphy (WBS) remains a widely used first‐line screening tool for bone metastasis, but differentiating MDP‐avid metastatic lesions from benign bone abnormalities in non‐small cell lung cancer (NSCLC) remains challenging. Purpose To develop and externally validate a radiomics and deep learning bone signature (RDB)

A Skull Bone Marrow‐to‐Brain Axis Links Osteoblastic Activity to Myeloid Cell Trafficking, Cerebral Blood Flow, and Cognition in Alzheimer's Progression

Advanced Science, Volume 13, Issue 43, 3 August 2026.
This study reveals that Alzheimer's disease–linked APP expression in bone‐forming cells drives skull bone marrow remodeling and alters its vascular connections to the brain. These changes disrupt immune cell trafficking, cerebral blood flow, and cognition. Targeting bone marrow macrophages restores brain function, highlighting a previously unrecognized
