Intelligence Loss in Phatic Disorders

Overview

Background.
Certain level of aphasia is considered to be an integral component of dementia. More controversial isthe question whether every -e .g. also strictly focal - aphasia must be accompanied with dementia.Methods and Results. 41 persons hospitalized after the cerebral stroke (17 men, 24 women, average age 64.6, 47to 89 years old) were tested to correlate the level of aphasia with mental and intelligence scores. 35 patients had anischaemic stroke, 6 had a hemorrhagic one; according to CT/MRI there were 37 patients with left sided impairment,one patient with a right sided one and 3 patients with bilateral lesions. As an aphasiologic test the Western AphasiaBattery (WAB) was used, to determine the general mental performance as an equivalent of IQ test the non-verbalRaven‘s and verbal Euro-ADAS test were used. Correlation analysis using non-parametric Spearman’s coefficientshowed a significant relation between results in phatic functions and the score in intelligence tests. Phatic performancehad in all elementary tests closer relation to verbal IQ in Euro-ADAS than with non-verbal IQ in Raven‘s test. Thehighest correlation was found in the relation between „apprehension vs. Euro-ADAS“ (-0,842) and „apprehensionvs. Raven“ (0,782), while the lowest correlation was found for „repetition vs. Euro-ADAS“ (-0,769), and „repetitionvs. Raven“ (0,646). The correlation was in all cases significant (p
