From Data to Diagnosis: Utilizing Deep Belief Networks for Early Parkinson's Disease Detection

Parkinson's disease is a progressive neurodegenerative disorder characterized by progressive deterioration of symptoms, whereby the afflicted individuals' standards of living are significantly diminished. Ideally, identification is the best practice for control and intervention; nevertheless, traditional approaches used in diagnosing may fail to detect the disease during its early stage. This paper aims to determine whether DBNs are suitable for detecting PD early since they can assess complicated and high-dimensional medical information. During the DBN modelling, the data used here were trained and tested using publicly available datasets, and the accuracy level recorded was 92 percent. In comparison, the sensitivity was 90 percent, and the specificity was 94 percent. The ROC-AVC of the timing of task execution was calculated to be 0. 95 percent in the diagnostic capacity, which indeed indicates the high level had been maintained. According to the above results, the DBN model provided superior performance to other diagnostic methods, which include a low false-negative rate. Traditional techniques, where the diagnosis depends on a doctor's assignment and imaging techniques, are usually less accurate and take more time to detect diseases early. It is crucial to note that this research proves the DBN model's feature of recognizing little deviations that hint at early-stage Parkinson's disease, making for a robust and practical diagnostic application. In clinical practice, the DBN model has been used numerous times, all of which pointed to the identification of early-stage Parkinson's disease patients who had not been diagnosed at all or were diagnosed with other disorders.
