Abstract

It is generally believed that early detection of neurodegenerative diseases will provide a much more sustainable framework for dealing with age-related diseases in the future. This chapter presents a strategic framework for the early diagnosis of neurodegenerative disease from gait discrimination to neural synchronization. Here, we propose and present a new classifier fusion strategy that combines classification algorithms and rules (voting, product, mean, median, maximum, and minimum) to measure specific behaviors in people with neurodegenerative diseases. On the other hand, it is now evident that electroencephalographic (EEG) signals of patients with Alzheimer disease usually have less synchronization than those of healthy subjects. Computing neural synchronization of EEG signals to detect any perturbation will help diagnose this fatal disease at an earlier stage. Three neural synchrony measurement techniques, phase synchrony, magnitude-squared coherence, and cross-correlation, are applied to analyze three different databases of mild Alzheimer disease patients and healthy subjects to compare the right and left temporal lobe of the brain with the rest of the brain area. Results are compared using Mann–Whitney U statistical test.

Introduction

Advancements in machine learning provoke new challenges by integrating data mining with biomedical sciences in the area of computer science. This emergent research line provides a multidisciplinary approach to combine engineering, mathematical analysis, computational simulation, and neuro-computing to solve complex problems in medical science. One of the most significant applications of machine learning is data mining. Data mining provides a solution to find out the relationships between multiple features, ultimately improving the efficiency of systems and designs of the machines. Data-mining techniques provide computer-based information systems to find out data patterns, generate information for the hidden relationships, and discover knowledge that unveils significant findings that are not accessible by traditional computer-based systems.

Neurodegenerative diseases (NDDs) are accompanied by the deterioration of functional neurons in the central nervous system. These include Parkinson, Alzheimer, Huntington, and amyotrophic lateral sclerosis (ALS) among others. The progression of these diseases can be divided into three distinct stages: retrogenesis, cognitive impairment, and gait impairment. Retrogenesis is the initial stage of any NDD which starts with the malfunctioning of the cholinergic system of the basal forebrain that further extends to the entorhinal cortex and hippocampus [1]. During retrogenesis, the patient’s memory is severely affected as a result of the accumulation of pathologic neurofibrillary plaques and tangles in the entorhinal cortex, hippocampus, caudate, and substantia nigra [2]. This stage is known as cognitive impairment. Finally, a patient cannot maintain his or her healthy, normal gait because of disturbances in the corticocortical and corticosubcortical connections in the brain, for example, frontal connection with parietal lobes and frontal lobes with the basal ganglia, respectively [3].

Early detection or diagnosis of life-threatening and irreversible diseases such as NDDs (Alzheimer, Parkinson, Huntington, and ALS) is an area of great interest for researchers from different academic backgrounds. Diagnosing NDDs at an earlier stage is hard, where symptoms are often dismissed as the normal consequences of aging. Moreover, the situation becomes more challenging where the symptoms or data patterns of different NDDs turn out to be similar, and discrimination among these diseases becomes as crucial as the treatment itself.
