Abstract Cognitive and behavioral disorders are subgroups of mental health disorders. Both cognitive and behavioral disorders can occur in people of different ages, genders, and social backgrounds and they can cause serious physical, mental or social problems. The risk factors for these diseases are numerous, with a range from genetic and epigenetic factors to physical factors. In most cases, the appearance of such a disorder in an individual is a combination of his genetic profile and environmental stimuli. To date, researchers have not been able to identify the specific causes of these disorders and as such, there is urgent need for innovative study approaches. The aim of the present study was to identify the genetic factors which seem to be more directly responsible for the occurrence of a cognitive and/or behavioral disorder. More specifically, through bioinformatics tools and software as well as analytical methods such as systemic data and text mining, semantic analysis, and scoring functions, we extracted the most relevant single nucleotide polymorphisms (SNPs) and genes connected to these disorders. All the extracted SNPs were filtered, annotated, classified, and evaluated in order to create the “genomic grammar” of these diseases. The identified SNPs guided the search for top suspected genetic factors, dopamine receptors D and Neurotrophic Factor BDNF, for which regulatory networks were built. The identification of the “genomic grammar” and underlying factors connected to cognitive and behavioral disorders can aid the successful disease profiling, the establishment of novel pharmacological targets and provide the basis for personalized medicine, which takes into account the patient’s genetic background as well as epigenetic factors.
