Table 2: Neuropsychological data.
Data were analyzed using non parametric statistics (Mann-Whitney test). SRT = Selective Reminding Test; LTS = Long Term Storage; CLTR = Consistent Long Term Retrieval; SPART = 10/36 Spatial Recall Test; SDMT= Symbod Digit Modalities Test; PASAT = Paced Auditory Serial Addition Task; WLG = Word List Generation; WCST= Wisconsin Card Sorting Test; te = total error; pe = perseverative error.
