Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

Annals of Neurology, Volume 100, Issue 2, Page 295-304, August 2026.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Combined Vitamin D and Resveratrol Treatment Attenuates Motor Deficits and Neurodegeneration in a 6‐OHDA Mouse Model of Parkinson's Disease in Male Mice: A Focus on Sirt1 and Lingo‐1 Pathways in the Ventral Tegmental Area

Brain and Behavior, Volume 16, Issue 8, August 2026.
Combined treatment with VitD3 and resveratrol mitigates motor deficits and neurodegeneration in 6‐OHDA‐lesioned mice which was associated with activation of Sirt1 and suppression of Lingo‐1. ABSTRACT Background Parkinson's disease (PD) is characterized by progressive dopaminergic neurodegeneration, leading to severe motor impairments.

The Neuroprotective Potentials of Dual GIP/GLP1‐RA (Tirzepatide): From Preclinical Experiments to Clinical Trials: A Scoping Review

Brain and Behavior, Volume 16, Issue 8, August 2026.
The graphical abstract summarizes the current evidence on the potential neuroprotective effects of tirzepatide (TZP), a dual GIP/GLP‐1 receptor agonist, across mechanistic, preclinical, and clinical domains. Mechanistically, TZP is proposed to exert direct neural effects, preserve mitochondrial function, reduce apoptosis, oxidative stress, and ...

Atypical Autonomic‐Predominant Guillain‐Barré Syndrome With Pandysautonomia Mimicking Parkinsonism and Recurrent Syncope: A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Guillain‐Barré syndrome with pandysautonomia can mimic neurodegenerative and cardiogenic conditions, particularly in elderly patients presenting with autonomic symptoms and parkinsonian features. Timely neurologic evaluation and ganglioside antibody testing—especially anti‐GM2—are essential for accurate diagnosis and the initiation of ...

Diabetic Striatopathy in a Middle‐Aged African Woman With Poorly Controlled Type 2 Diabetes Mellitus and HIV Coinfection—A Case Report

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Diabetic striatopathy is a reversible cause of acute chorea occurring in patients with poorly controlled diabetes mellitus, including those even with complex comorbidities like HIV. Timely neuroimaging and prompt metabolic correction are crucial, emphasizing the need for high clinical suspicion.
