Neural correlates of transitive and intransitive action imitation: An investigation using voxel-based morphometry

NeuroImage: Clinical, 2014
The ability to reproduce visually presented actions has been studied through neuropsychological observations of patients with ideomotor apraxia. These studies include attempts to understand the neural basis of action reproduction based on lesion–symptom ...

Blood‐based Alzheimer's disease biomarkers in a behavioral neurology clinic: Real‐world implementation, clinical utility, and diagnostic performance

Alzheimer's &Dementia, Volume 21, Issue 11, November 2025.
Abstract INTRODUCTION Blood‐based biomarkers (BBMs) for Alzheimer's disease (AD), including plasma phosphorylated tau (p‐tau), are increasingly used in clinical practice, but “real‐world” implementation patterns, context‐of‐use (COU), clinical utility, and diagnostic performance are incompletely understood. METHODS A retrospective analysis of the first

Primary progressive apraxia: an unusual ideomotor syndrome [PDF]

Journal of Clinical Movement Disorders, 2017
Primary progressive apraxia is a rare form of apraxia in the absence of dementia which develops insidiously and is slowly progressive. Most reports of patients with apraxia also describe coexisting aphasias or involve additional apraxias with affected speech, usually in the setting of neurodegenerative diseases such as corticobasal degeneration ...

Dysphagia and Mortality Risk in Individuals With Primary Progressive Apraxia of Speech

Annals of Clinical and Translational Neurology, Volume 12, Issue 7, Page 1493-1498, July 2025.
ABSTRACT Individuals with primary progressive apraxia of speech (PPAOS) often develop parkinsonism and dysphagia. To evaluate the clinical correlates and impact of dysphagia in this population, we compared enrollment visit data between individuals with (n = 12) versus individuals without (n = 44) dysphagia symptoms.

Dissecting the Phenotypic Spectrum and Complexity of Movement Disorders in 22q11.2 Deletion Syndrome

European Journal of Neurology, Volume 32, Issue 6, June 2025.
In this study, we deeply phenotyped 31 unrelated adults with molecular confirmation of 22q11.2 microdeletion who were referred for neurologic assessments at a major centre of excellence in movement disorders. At the group level, majority (77%) presented with two or more movement disorder phenotypes, with similar trends in prevalence after accounting ...
