Prevalence and implications of psychopathological non-cognitive symptoms in dementia

ACTA PSYCHIATRICA SCANDINAVICA, Issue 2 2009
P. Saz
Objective:, Clinical experience and recent population studies suggest that psychopathological, non-cognitive symptoms are both frequent and relevant in dementia. Method:, A representative community sample (n = 4,803 individuals, 55 + years) was interviewed in a two-phase design. The Geriatric Mental Sate (GMS) was used for assessment and cases were diagnosed according to DSM-IV-TR criteria. Results:, The prevalence of non-cognitive symptoms (1 + symptoms) in cases of dementia (n = 223) was 90.1%, and negative-type symptoms were most frequently found. A GMS ,apathy-related symptom cluster' (anergia, restriction of activities and anhedonia) was significantly more frequent in the demented (55.6%) than in non-cases (0.7%; specificity = 99.2%). In both dementia of Alzheimer's type and vascular dementia, number of symptoms tended to be inversely related to severity of dementia, but psychopathological profiles differed. Conclusion:, Non-cognitive, negative-type symptoms are very frequent in cases of dementia living in the community. They have powerful specificity in the distinction with non-cases, and might change current concepts of dementia. [source]

Frontotemporal dementia: patient characteristics, cognition, and behaviour

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 10 2002

Abstract Objectives To describe sociodemographic data of patients with frontotemporal dementia (FTD), to compare the cognitive profile of patients with FTD with that of severity-matched patients with Alzheimer's disease using the CERAD neuropsychological battery (CERAD-NP), to investigate the frequency of behavioural disturbances, and to examine the relation between FTD-specific non-cognitive behavioural symptoms of patients with FTD with age and sex. Methods Fifty outpatients were diagnosed with FTD according to the Lund-Manchester consensus criteria. Cognitive impairment was assessed in 30 patients using the CERAD-NP. Severity of dementia was rated on the Clinical Dementia Rating (CDR). Eleven non-cognitive symptoms were rated by severity. To compare CERAD-NP results between patients with FTD and AD, 30 patients with AD were matched for age, sex, and global severity of cognitive performance. Results The average age at onset of first symptoms was 57.8 years. Eighteen patients (36%) had a positive family history of dementia. On the CERAD-NP patients with FTD performed significantly better than patients with AD on word list learning, delayed verbal recall and visuoconstruction (p<0.05). There were no significant differences between FTD and AD on naming and verbal fluency tasks. The most frequent non-cognitive behavioural symptoms in FTD were loss of insight, speech abnormality, and apathy. Non-cognitive behavioural symptoms were more frequent in younger and in male than in older patients and in female patients. Conclusions The CERAD-NP is a valuable clinical instrument for the cognitive evaluation of patients with suspected FTD. Complementary short tests of attention and executive function may be recommended. To enhance diagnostic sensitivity informant interviews should focus on non-cognitive behavioural changes, taking advantage of standardised questionnaires. Copyright © 2002 John Wiley & Sons, Ltd.

Cognitive Impairment Questionnaire (CIMP-QUEST): reported topographic symptoms in MCI and dementia

Åstrand R, Rolstad S, Wallin A. Cognitive Impairment Questionnaire (CIMP-QUEST): reported topographic symptoms in MCI and dementia. Acta Neurol Scand: 2010: 121: 384,391. © 2009 The Authors Journal compilation © 2009 Blackwell Munksgaard. Objective,,, The Cognitive Impairment Questionnaire (CIMP-QUEST) is an instrument based on information obtained by key informants to identify symptoms of dementia and dementia-like disorders. The questionnaire consists of three subscales reflecting impairment in parietal-temporal (PT), frontal (F) and subcortical (SC) brain regions. The questionnaire includes a memory scale and lists non-cognitive symptoms. The reliability and validity of the questionnaire were examined in 131 patients with mild cognitive impairment (MCI) or mild dementia at a university-based memory unit. Methods/Results,,, Cronbach alpha for all subscales was calculated at r = 0.90. Factor analysis supported the tri-dimensionality of CIMP-QUEST's brain region-oriented construct. Test,retest reliability for a subgroup of cognitively stable MCI-patients (n = 25) was found to be r = 0.83 (P = 0.0005). The correlation between the score on the cognitive subscales (PT + F + M) and Informant Questionnaire on Cognitive Decline in the Elderly was r = 0.83 (P = 0.0005, n = 123). The memory subscale correlated significantly with episodic memory tests, the PT subscale with visuospatial and language-oriented tests, and the SC and F subscales with tests of attention, psychomotor tempo and executive function. Conclusions,,, CIMP-QUEST has high reliability and validity, and provides information about cognitive impairment and brain region-oriented symptomatology in patients with MCI and mild dementia.
