Abstract Alzheimer’s disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the socalled Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does not seem sufficiently severe to interfere in independent abilities of daily life, so it is usually diagnosed inappropriately. Thus, its detection is a crucial challenge to be addressed by medical specialists. This paper presents a novel proposal for such early diagnosis based on automatic analysis of speech and disfluencies, and Deep Learning methodologies. The proposed tools could be useful for supporting Mild Cognitive Impairment diagnosis. The Deep Learning approach includes Convolutional Neural Networks and nonlinear multifeature modeling. Additionally, an automatic hybrid methodology is used in order to select the most relevant features by means of nonparametric Mann–Whitney U test and Support Vector Machine Attribute evaluation.

1 Introduction Alzheimer’s disease (AD) is characterized by a progressive and irreversible cognitive deterioration, which includes memory loss and impairments in emotion, language, and judgment, along with other cognitive deficits and symptoms in behavior. Its prevalence keeps increasing mainly
among the elderly, and as highlighted by the last World Alzheimer Reports, AD is becoming epidemic as 900 million people can be regarded as the world’s elderly population, living most of them in developed countries [1]. Therefore, an early and accurate diagnosis of AD helps patients and relatives to plan the future and offers the best possibilities that symptoms could be treated.
