Mapping Intracellular Volume Fraction With Susceptibility Source Decomposition as a Marker for Tissue Cellularity

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Pathophysiological changes affect tissue cell composition and density. For example, neurodegenerative disorders and brain tumors are associated with cell loss and abnormal accumulation, respectively. In these scenarios, if monitored and tracked, tissue cellularity might be used to inform clinical diagnosis and management. Purpose To

Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Cognition improvement in U.S. veterans undergoing treatment for posttraumatic stress disorder: Secondary analyses from a randomized controlled trial

Journal of Traumatic Stress, EarlyView.
Abstract Cognitive dysfunction is a hallmark of posttraumatic stress disorder (PTSD). Although treatments effectively reduce core PTSD symptoms, limited research has examined whether associated cognitive impairments improve following treatment.

Prodromal Lewy Body Symptoms and α‐Synuclein Seeding in Idiopathic Olfactory Dysfunction

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Early identification of pathological α‐synuclein deposition (αSynD) may improve understanding of Lewy body disorder (LBD) progression and enable timely disease‐modifying treatments. Objectives We investigated αSynD using a seed amplification assay and assessed prodromal LBD symptoms in individuals with idiopathic olfactory ...

Basal Forebrain Volume and Concurrent Hallucinations and Mild Cognitive Impairment in Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Visual hallucinations (VH) and mild cognitive impairment (MCI) often co‐occur in Parkinson's Disease (PD). Each symptom in isolation is associated with cholinergic basal forebrain (BF) atrophy. However, it is unclear whether BF integrity relates to one symptom preferentially or to their co‐occurrence, and whether this relationship ...
