Hippocampal connectivity dynamics and volumetric alterations predict cognitive status in migraine: A resting-state fMRI study.

The etiology of cognitive decline linked to migraine remains unclear, with a growing recurrence rate and potential increased dementia risk among sufferers. Cognitive dysfunction has recently gained attention as a significant problem among migraine sufferers that can be related to alterations in hippocampal function and structure. This study explores hippocampal subfield connectivity and volume changes in migraine patients.

Visuoperceptual rehabilitation with repetitive transcranial magnetic stimulation in chronic cortical blindness: a case report.

This study aims to reveal the effect of visuoperceptual rehabilitation combined with neuromodulation on visual impairment recovery in chronic cortical blindness. A 71-year-old patient with cortical blindness was assessed using perimetry, pattern electroretinogram (pERG), Canadian Occupational Performance Measurement (COPM), and Montreal Cognitive Assessment (MoCA) at baseline and after treatment. After 12 rTMS sessions and 50 visual perceptual rehabilitation sessions, perimetry, pERG, COPM, and MoCA significantly improved the visual field and daily functioning.

Parietal memory network and memory encoding versus retrieval impairments in PD-MCI patients: A hippocampal volume and cortical thickness study.

Objective: The pathophysiology behind memory impairment in Parkinson's Disease Mild Cognitive Impairment (PD-MCI) is unclear. This study aims to investigate the hippocampal and cortical atrophy patterns in PD-MCI patients with different types of memory impairments, categorized as Retrieval Failure (RF) and Encoding Failure (EF).

Methods: The study included 16 healthy controls (HC) and 34 PD-MCI patients, divided into RF (N = 18) and EF (N = 16) groups based on their Verbal Memory Processes Test (VMPT) scores, including spontaneous recall, recognition, and Index of Sensitivity to Cueing (ISC).

Multi-omics analysis reveals the key factors involved in the severity of the Alzheimer's disease.

Alzheimer's disease (AD) is a debilitating neurodegenerative disorder with a global impact, yet its pathogenesis remains poorly understood. While age, metabolic abnormalities, and accumulation of neurotoxic substances are potential risk factors for AD, their effects are confounded by other factors. To address this challenge, we first utilized multi-omics data from 87 well phenotyped AD patients and generated plasma proteomics and metabolomics data, as well as gut and saliva metagenomics data to investigate the molecular-level alterations accounting the host-microbiome interactions.

Smoking affects global and regional brain entropy in depression patients regardless of depression: Preliminary findings.

Objective: This study examines the effect of smoking on global and regional brain entropy in patients with Major Depressive Disorder (MDD), aiming to elucidate the relationship between smoking habits and brain network complexity in depression.

Methods: The study enrolled 24 MDD patients, divided into smokers and non-smokers, from Alanya Alaaddin Keykubat University and Istanbul Medipol University. Resting-state fMRI data were acquired and processed.
