Neuropsychiatric symptoms are common in patients with cognitive impairments, mediated by both neurodegenerative processes and cerebrovascular disease. Previous studies have reported that Behavioral and Psychological Symptoms of Dementia (BPSD) might correlate with severity of cognitive decline. Thus far, the impact of the association between white-matter hyperintensities (WHM) and hippocampal atrophy (HA) on the incidence of these symptoms has beenless studied.
Objective:
This cross-sectional study aimed to describe the clinical profile of a sample with large extensions of WMH, examining the association between different degrees of HA and cognitive, functional, and behavioral status.Methods:
Fifty outpatients (mean age: 76.86±8.70 years; 58% female; mean schooling: 7.44±4.69 years) with large extensionsof WMH (modified-Fazekas scale=3) on MRI and different degrees of hippocampal atrophy (according to de Leon Score)underwent cognitive, functional, and behavioral assessments.Results:
Patients with mild-moderate to severe HA had worse performance on the Mini-Mental State Examination, Cambridge Cognitive Examination, Clinical Dementia Rating and Pfeffers Functional Activities Questionnaire, compared to the group with none or questionable HA. Appetite/Eating Behavior wasthe only cluster of neuropsychiatric symptoms associated with presence of HA in Vascular Cognitive Impairment patients.Discussion:
Although HA may exhibit distinct impact on cognitive performance and functional status, it appears to havelittle effect on behavioral symptoms in patients with high severity WMH.
Sintomas neuropsiquiátricos são comuns em pacientes com déficits cognitivos associados aprocessos neurodegenerativos e à doença cerebrovascular. Estudos apontaram que os Sintomas Comportamentais ePsicológicos da Demência (SCPD) podem ter relação com a gravidade do declínio cognitivo. Até o presente, o impacto daassociação entre hiperintensidades da substância branca (HSB) e atrofia hipocampal (AH) sobre esses sintomas foi poucoexplorado na literatura.
