Machine Learning Holds Promise in Neurodegenerative Disease Research
Machine learning methods are proving to be valuable tools in the field of neurodegenerative disease research, offering insights into diagnosis, prognosis, and treatment prediction. A recent scoping review published on the medRxiv preprint server delves into the growing utility of these methods for the study of prevalent neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, amyotrophic lateral sclerosis, and Huntington’s disease.
Neurodegenerative diseases are age-related conditions characterized by the progressive deterioration of the nervous system, resulting in debilitating symptoms that ultimately lead to loss of independence and, in some cases, death. With Alzheimer’s disease and Parkinson’s disease being the most common neurodegenerative diseases in the United States, affecting millions of people, the need for improved management strategies is urgent, especially as life expectancy continues to rise.
To gain deeper insights into these incurable diseases, researchers are increasingly turning to machine learning methods to analyze disease-related data with speed and accuracy, essential for driving diagnostic and therapeutic innovations. The reviewed studies covered the period from January 2016 to December 2020 and revealed a steady increase in the use of machine learning methods, with a 185% rise in incorporation from 2016 to 2020.
Imaging emerged as the most commonly analyzed data type, followed by functional, clinical, biospecimen, genetic, electrophysiological, and molecular analyses. Notably, imaging data played a significant role in Alzheimer’s disease research, while functional data took precedence in Parkinson’s disease studies. Machine learning methods were primarily employed for disease diagnosis, prognosis, and treatment effect prediction, with imaging data being the go-to choice for diagnosis and prognosis, while functional data was widely used for treatment effect prediction.
The data from the reviewed studies revealed an extensive array of machine learning methods, including support vector machine, random forest, and convolutional neural network. Undoubtedly, machine learning is paving the way for advancements in neurodegenerative disease research, as it aids in the identification of prognostic biomarkers and the discovery of novel therapeutic approaches.
It is important to note that the findings presented in this scoping review are preliminary and not yet peer-reviewed, meaning they should not be considered conclusive or used as evidence to guide clinical practice or healthcare decisions.
As the field of machine learning continues to evolve, its potential in neurodegenerative disease research is becoming increasingly evident. By harnessing the power of this technology, researchers can accelerate progress towards the development of effective treatments and proactive management strategies for these devastating diseases.
