Abstract

Gray level co-occurrence texture characteristics of digital drawings were compared between persons with early dementia of Alzheimer’s disease and healthy controls. It was hypothesized that texture characteristics contribute to the differentiation between these subject groups. The study population consisted of 67 healthy subjects and 56 patients with early dementia of Alzheimer’s type. Between subject groups comparisons of texture entropy, homogeneity, correlation and image size were conducted with Mann-Whitney-U tests. The diagnostic power of combining all texture features as explanatory variables was analysed with a logistic regression model and the area under curve (AUC) of the corresponding receiver operating control (ROC) curve was calculated. The gray level co-occurrence characteristics differed significantly between healthy and demented subjects and the logistic regression model resulted in an AUC of 0.86 (95% CI [0.80, 0.93], sensitivity=.80, specificity=.79).
