Las Vegas: The National Institute of Neurological Disorders and Stroke at the National Institutes of Health (NIH) has awarded a grant expected to total $3.8 million to Virendra Mishra, Ph.D., associate staff at Cleveland Clinic Lou Ruvo Center for Brain Health, to identify biomarkers or disease indicators to predict dementia in patients with Parkinsons disease.

Although dementia affects approximately 50-80% of those living with Parkinsons disease within 12 years of diagnosis, currently there are no means for predicting dementia in specific individuals, said Mishra. The possibility of identifying who will develop dementia with Parkinsons disease progression has several clinical benefits, including providing individuals with greater clarity on their future and helping clinicians better manage disease progression.

The five-year grant supports the project, Towards Generating a Multimodal and Multivarate Classification Model from Imaging and Non-Imaging Measures for Accurate Diagnosis and Monitoring of Dementia in Parkinsons Disease, which will use biomarkers spanning imaging, blood, cerebrospinal fluid and genetics to develop a predictive mathematical model to identify specific individuals with Parkinsons disease who may develop dementia as their disease progresses.

Utilizing sophisticated and pathologically relevant neuroimaging measures such as diffusion-weighted MRI and resting state functional MRI with non-imaging measures, including clinical data, demographics, genetics and cerebrospinal fluid, Mishra aims to:

Through this research, Mishra plans to develop a method that can be applied in clinical care with a greater-than-chance success rate to improve patient outcomes. In addition to clinical implications, identifying pathophysiology-based biomarkers for dementia in Parkinsons disease is critical for selecting appropriate individuals for participation in clinical trials of potential new disease-modifying therapies, and better understanding of the underlining pathophysiological processes.

Additionally, the novel imaging techniques developed for this research also can be applied in other neurodegenerative diseases such as Alzheimers disease to help advance the understanding of disease-specific neuroanatomical changes indicative of dementia.

This project is supported by NIH grant award R01NS117547.
