Insight Impairment in Patients with Cognitive Impairment

Objective: To investigate the insight impairment in patients with cognitive impairment and the influencing factors.Methods: Eighty-one patients with cognitive impairment were recruited.The clinical dementia rating(CDR),anosognosia questionnaire-dementia(AQ-D),mini-mental state examination(MMSE),activities of daily living(ADL) and geriatric depression scale(GDS) were used to assess the patients and the scores were analyzed.Results: Insight impairment was documented in 28 patients(34.5%) in this study.Furthermore,extent of insight impairment was associated with the degree of cognition impairment.The score of AQ-Dd correlated with the scores of MMSE,ADL and CDR,but was independent of the sex,age,length of education,and score of GDS.Types of dementia had no influence on the insight impairment.Conclusion: Insight impairment is evident in a part of patients with cognitive impairment.The severity of insight impairment is closely correlated with cognitive ability,action ability and severity of dementia.
