“…The validity of the GDS-15 for other age groups, like younger and adults, has already been reported in the literature (19) . The cognitive abilities were assessed by the Instrument of Brief Neuropsychological Assessment (NEUPSLIN) (20) , which is an instrument with a brief administration time aiming at verifying preserved and impaired abilities in components of eight different cognitive functions, giving support to a neuropsychological diagnosis. It includes the following tasks, all of them administered in this study: Concentrated attention (inverted counting and digit repetition); Visual perception (verification of similarities and differences of lines, hemineglect, faces perception and recognition); Working memory (ascendant ordering of digits and auditory span of words in sentences); Episodic-semantic verbal memory (delayed and immediate recall and word list recognition); Long-term semantic memory; Short-term visual memory (figures); Prospective memory; Arithmetic abilities (simple addition, subtraction, multiplication and division calculation); Oral language (objects and figures' naming, words and non-words' repetition, automatic language, inference comprehension and processing); Written language (reading aloud of words and non-words, written comprehension, spontaneous writing, copying, words and non-words dictation); Apraxia (ideomotor, constructive and reflexive), and Executive functions (simple problems' resolution and orthographic verbal fluency -letter F).…”
