LEDESMA-AMAYA, LUIS I. et al. NEUROPSYCHOLOGICAL DISORDERS ASSOCIATED WITH PATIENTS WITH LACUNAR INFARCT. Act.Colom.Psicol. [online]. 2014, vol.17, n.2, pp.43-52. ISSN 0123-9155.  https://doi.org/10.14718/ACP.2014.17.2.5.

There is little evidence of cognitive impairment to define the profile of patients with Lacunar Infarction (IL). The purpose of this study was to identify the neuropsychological disorders in these patients. The sample consisted of 16 patients with IL and 16 healthy control participants with an average age of 63 ± 9.41 and 64.75 ± 9.06 years, and average schooling of 7.55 ± 4.34 and 7.94 ± 3.51, respectively. Cognitive function was assessed using a screening tool and a neuropsychological battery. Statistical analysis was carried out by the Kruskal-Wallis and Mann-Whitney U tests. Patients with IL are characterized by the alteration of domains such as planning, verbal fluency, attention switching, visoconstructive skill and information processing speed (p <0.050). The IL is related to the impairment of executive functioning and processing speed, due to the interruption of frontocortico-subcortical circuits associated with their proper performance.
