Our study aims to contribute to the development of computer-aided diagnosis (CAD) systems to aid in the early diagnosis of Alzheimer's disease (AD) and frontotemporal dementia (FTD) by examining Electroencephalogram (EEG) signals. EEG signals of 36 AD, 23 FTD and 29 healthy control (HC) participants were analyzed and entropy measurement approaches were used to analyze the connectivity between EEG channel pairs. The cross-permutation entropy (CPE) method and the cross conditional entropy (CCE) method were analyzed separately and the fused cross entropy (FCE) method was also tested by combining these techniques to determine the most appropriate method for feature extraction from EEG signals. The features obtained from these techniques were then evaluated in the classification phase using two separate machine learning algorithms. According to the performance evaluation criteria, the FCE and artificial neural network (ANN) model showed the most successful performance in the classification of all groups. In terms of area under the curve (AUC) and accuracy rates, 99.85% AUC and 98.46% accuracy were obtained in AD&HC groups, 99.71% AUC and 98.10% accuracy in FTD&HC groups and 99.39% AUC, 96.61% accuracy in AD&FTD groups.

Specifically, we argue that when experiencing obsessions, weak cognitive control is favored due to the affective cost of disregarding anxiety-provoking obsessions (akin to ignoring a fire alarm). This affective cost leads to the overvaluation of the cost of cognitive control (deeming it expensive), favoring automatic responses in the form of compulsions. We also exercise other ways by which OCD symptoms can be explained within the same theoretical framework. We ground our EVC-based neuroeconomic account in different neural systems implicated in OCD, including the orbitofrontal cortex, dorsal anterior cingulate cortex (dACC), dorsolateral prefrontal cortex, and basal ganglia, which refer to different EVC constituents.
