Unmet Need: Automated neuroimaging for detection of Alzheimer’s disease and preceding states
Therapeutic interventions at the early stages of Alzheimer’s disease (AD) have been shown to slow disease progression. Therefore, developing methods for early detection of Alzheimer’s disease is critical. Diagnostic modalities are limited and underdeveloped since MRI scans require visual inspection by trained medical professionals. Automated deep learning-based algorithms show great promise in their application to neuroimaging diagnostics, yet current deep learning MRI technologies are inaccurate in their ability to classify diseases.
The Technology: Application of deep learning-based neuroimaging modalities for accurate classification of Alzheimer’s disease and detection at early stages.
This technology is a machine learning tool that utilizes 3D deep convolutional neural networks for classification of Alzheimer’s disease and for detection of early-stage disease. The method is based on longitudinal data from structural MRI scans. The algorithm performs in-depth regional analysis to localize the most predictive areas, in addition to analyzing whole brain volumes. This technology can be used to classify states of mild cognitive impairment as well as predict the likelihood of progression to Alzheimer’s disease.
This technology was able to accurately classify patients that already had mild cognitive impairment, as well as predict the likelihood of progression to AD.
Applications:
- Automated deep learning-based MRI tool for classification of Alzheimer’s disease and detection of early-stage disease
- Automated tool for monitoring of patients for early-stage disease progression
- Research tool for development of machine learning-based imaging modalities for detection of
other diseases
Advantages:
- Utilization of 3D deep convolutional neural networks
- In-depth regional analyses
- Increased predictive accuracy in detecting mild cognitive impairment
