Over recent years, the retina has been increasingly investigated as a potential biomarker for dementia. A number of studies have looked at the effect of Alzheimer's disease (AD) pathology on the retina and the associations of AD with visual deficits. However, while OCT-A has been explored as a biomarker of cerebral small vessel disease (cSVD), studies identifying the specific retinal changes and mechanisms associated with cSVD are lacking.

Gamma oscillations are essential for brain communication. The 40 Hz neural oscillation deficits in schizophrenia impair left frontotemporal connectivity and information communication, causing auditory hallucinations. Transcranial alternating current stimulation is thought to enhance connectivity between different brain regions by modulating brain oscillations.

Lymphocytic esophagitis (LE) is an uncommon subtype of esophagitis defined by persistent esophageal inflammation characterized by a high count of intraepithelial lymphocytes with scarce granulocytes. Although LE can present with atypical features such as chest pain, its clinical presentation can mimic that of gastroesophageal reflux disease or eosinophilic esophagitis, highlighting the importance of biopsy in diagnosing LE. Studies are still limited in understanding the pathophysiology behind this disease warranting further research.

Introduction: Central Post-Stroke Pain (CPSP) is a debilitating condition with a significant prevalence in stroke survivors. Set apart by its refractory to treatment neuropathic pain, it appears to arise from lesions in the spino-thalamo-cortical pathways, particularly in the thalamus. Despite advances in neuroimaging techniques, the pathophysiology of CPSP remains poorly understood, with limited diagnostic criteria and therapeutic approaches.
