Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration

Advanced Science, EarlyView.
This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

Synthetic MRI Neuroimaging Correlates of Frailty: Correlations Between Frailty Scales and Brain Structural Integrity

AGING MEDICINE, EarlyView.
Frailty was associated with decreased gray and white matter brain volumes in older adults. Synthetic MRI further revealed relaxometry alterations correlated with frailty severity across multiple clinical scales. ABSTRACT Objectives Frailty, a common condition in the elderly, is characterized by a decline in physiological reserves and an increased ...

Interaction of FXTAS Family History and College Degree Attainment Predicts Trajectories of Cognitive and Motor Symptoms in FMR1 Premutation Carrier Women

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT The present longitudinal study focuses on FMR1 premutation carrier women during midlife and early old age (n = 115). Bringing together the genetic risk factor of a family history of FXTAS and the environmental protective factor of higher education, the goal of the study was to determine how these factors potentially interact to predict self ...

Assessment of Genetic Correlations Between Tobacco or Alcohol Use and Neurodegenerative Diseases Using East Asian Genetic Ancestry Genome‐Wide Association Study Results

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Alzheimer's disease (AD) and Parkinson's disease (PD) are the most prevalent late‐onset neurodegenerative diseases worldwide. Both are influenced in part by genetic factors and are currently incurable. Tobacco and alcohol, the two most common substances used among the general adult population, are potential AD/PD risk factors and are also ...

Retinal Nerve Fiber Layer Thinning in Dementia Associated with Parkinson's Disease, Dementia with Lewy Bodies, and Alzheimer's Disease

, 2013
Optical coherence tomography is a simple, high-resolution technique to quantify the thickness of retinal nerve fiber layer (RNFL). Previous studies have shown that degenerative changes occur in optic nerve fibers and are manifested as thinning of RNLF in

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

Animal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...

Speech Biomarkers for Quantifying Effects of Subthalamic Deep Brain Stimulation in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective Dysarthria is one of the most common and disabling side effects of subthalamic nucleus deep brain stimulation (STN‐DBS) in Parkinson's disease (PD). Stimulation often exacerbates speech dysfunction beyond the effects of PD progression, likely because of current spread to structures surrounding the STN.

Longitudinal Changes in Cognition in Parkinson’s Disease with and without Dementia

, 2011
<i>Background:</i> The longitudinal cognitive course in Parkinson’s disease (PD) with and without dementia remains undefined. We compared cross-sectional models of cognition in PD (both with and without dementia), Alzheimer’s disease (AD ...
