Relation between frontal lobe symptoms and dementia severity within and across diagnostic dementia categories.

Background: To study frontal lobe symptoms in relation to dementia severity within and across diagnostic dementia categories, a cross-sectional analysis of behavioural data was performed.

Methods: Patients with probable Alzheimer's disease (AD) (n = 456), frontotemporal dementia (FTD) (n = 55) and dementia with Lewy bodies (DLB) (n = 48) were included. Dementia severity and frontal lobe symptoms were assessed by means of the global deterioration scale and the Middelheim frontality score (MFS).

Verbal cued recall as a predictor of conversion to Alzheimer's disease in Mild Cognitive Impairment.

Objective: This study was set up to investigate whether neuropsychological tests are able to predict conversion to AD among Mild Cognitive Impairment (MCI) patients.

Methods: At baseline the cognitive part of the Cambridge Examination for Mental Disorders of the Elderly (CAMCOG), the Mini Mental Status Examination (MMSE), the Geriatric Depression Scale (GDS), a Dutch variation of Rey's Auditory Verbal Learning Test, the Memory Impairment Screen plus (MISplus) and the Visual Association Test (VAT) were administered to 40 patients diagnosed with MCI. After 18 months, MCI-patients were reassessed and a follow-up diagnosis was established.

Is the geriatric depression scale a reliable screening tool for depressive symptoms in elderly patients with cognitive impairment?

Objective: To determine the reliability of the 30-item Geriatric Depression Scale (GDS-30) for the screening of depressive symptoms in dementia and mild cognitive impairment (MCI) using the Cornell Scale for Depression in Dementia (CSDD) as the 'gold standard'.

Methods: Diagnosed according to strictly applied clinical diagnostic criteria, patients with MCI (n = 156) and probable Alzheimer's disease (AD) (n = 247) were included. GDS-30, CSDD, Mini Mental State Examination (MMSE) and Global Deterioration Scale were assessed in all patients at inclusion.

Differentiation between dementia and depression among older persons: can the difference between actual and premorbid intelligence be useful?

We wanted to investigate whether the difference between actual and premorbid intelligence can be useful to make an early differentiation between Alzheimer's disease (AD) and depression among elderly. A Dutch version of the National Adult Reading Test (NLV), a measure of premorbid IQ and the Raven Coloured Progressive Matrices (RCPM), a measure of actual intelligence were administered to patients with mild (34) and moderate (27) AD, depressed elderly (36) and healthy control subjects (51). Logistic regression analyses revealed that intellectual decline (i.

The dopaminergic neurotransmitter system is associated with aggression and agitation in frontotemporal dementia.

To identify neurochemical correlates of behavioral and psychological signs and symptoms of dementia (BPSD), we set up a prospective study. Patients with probable Alzheimer's disease (AD) (n=181), mixed dementia (MXD) (n=28), frontotemporal dementia (FTD) (n=25) and dementia with Lewy bodies (DLB) (n=24) were included. At inclusion, all patients underwent lumbar puncture, neuropsychological examination and behavioral assessment (battery of behavioral assessment scales).
