Congratulations to Drs. David Vaillancourt, Melissa Armstrong and Karen McFarland on the publication of “Diffusion MRI relates to plasma Aβ42/40 in PET negative participants without dementia,” which appears in the March edition of Alzheimer’s and Dementia.
Abstract
Magnetic resonance imaging (MRI) biomarkers are needed for indexing early biological stages of Alzheimer’s disease (AD), such as plasma amyloid‐β (Aβ42/40) positivity in Aβ positron emission tomography (PET) negative individuals. METHODS Diffusion free‐water (FW) MRI was acquired in individuals with normal cognition (NC) and mild co ..read more

Congratulations to Dr. Michael Okun on the publication of his position paper “U.S. Tax Credits to Promote Practical Proactive Preventative Care for Parkinson’s Disease,” which appears in the March edition of the Journal of Parkiinson’s Disease.
Abstract
Persons with Parkinson’s disease (PD) and society at large can profit from a strategic investment into a forward leaning, practical, preventative, and proactive multidisciplinary care policy. The American healthcare system is not easily bent to accommodate this type of care, and thus a tax benefit is an attractive option. An individual federal ..read more

Congratulations to Dr. Aparna Shukla on the publication of “Rhythmic Jaw Movements in Amyotrophic Lateral Sclerosis: Is It Clonus or Tremor?,” which appears as a video abstract in Tremor and other Hyperkinetic Movements.
Abstract
Background: Jaw clonus refers to involuntary, rhythmic jaw contractions induced by a hyperactive trigeminal nerve stretch reflex; however, the movements, when triggered without a stretch, can be confused with a tremor.
Phenomenology Shown: This video demonstrates a patient with amyotrophic lateral sclerosis presenting with rapid rhythmic jaw movements seen a ..read more

Congratulations to Drs. Michael S. Okun, Kelly D. Foote, and Aysegul Gunduz, on the publication of ” Neuromodulation for the treatment of Prader-Willi syndrome – A systematic review,” which appears in the April edition of Neurotherapeutics.
Abstract
Prader-Willi syndrome (PWS) is a complex, genetic disorder characterized by multisystem involvement, including hyperphagia, maladaptive behaviors and endocrinological derangements. Recent developments in advanced neuroimaging have led to a growing understanding of PWS as a neural circuit disorder, as well as subse ..read more

Congratulations to Drs. Shannon Chiu, Melissa Armstrong and David Vaillancourt on the publication of ” Longitudinal Free-Water Changes in Dementia with Lewy Bodies,” which was published in March 2024 edition of Movement Disorders.
Abstract
Background: Diffusion-weighted magnetic resonance imaging (dMRI) examines tissue microstructure integrity in vivo. Prior dementia with Lewy bodies (DLB) diffusion tensor imaging studies yielded mixed results.
Objective: We employed free-water (FW) imaging to assess DLB progression and correlate with clinical decline in DLB.
Methods: Baseline a ..read more

New research published today suggests there is a link between abnormal blood levels of amyloid — a protein associated with Alzheimer’s disease — and subtle changes in brain microstructures on a type of MRI, findings that could lead to a new way to detect Alzheimer’s earlier in people with no clinical signs.
Researchers analyzed the results of 128 human participants with and without dementia from the 1Florida Alzheimer’s Disease Research Center who underwent imaging scans using an established diagnostic tool called positron emission tomography, or PET, which can detect amyloid plaques ..read more

Congratulations to Dr. Christopher Butson on the publication of “Thalamic deep brain stimulation in traumatic brain injury: a phase 1, randomized feasibility study,” which appears in the December 2023 issue of Nature Medicine.
Abstract
Converging evidence indicates that impairments in executive function and information-processing speed limit quality of life and social reentry after moderate-to-severe traumatic brain injury (msTBI). These deficits reflect dysfunction of frontostriatal networks for which the central lateral (CL) nucleus of the thalamus is a critical node. The primary objective o ..read more
