Purpose: The Tailored Activity Program (TAP) is a home-based occupational therapy intervention shown to reduce behavioral symptoms and caregiver burden in a randomized trial. This article describes TAP, its assessments, acceptability, and replication potential.; Design and Methods: TAP involves 8 sessions for a period of 4 months. Interventionists identify preserved capabilities, previous roles, habits, and […]
Cued recall and other cognitive tasks to facilitate dementia recognition in primary care
Objectives: To compare the accuracy of commonly used tasks with that of the Visual Association Test (VAT), a conceptually different test involving cued recall of pictorial stimuli, in the recognition of dementia within primary care.; Design: A cross-sectional diagnostic study of concurrent validity.; Setting: Twenty-nine German primary care practices.; Participants: Four hundred twenty-three individuals in […]

Brain magnetic resonance imaging (MRI) studies have demonstrated regional patterns of brain macrostructural atrophy and white matter microstructural alterations separately in the three major subtypes of frontotemporal lobar degeneration (FTLD), which includes behavioral variant frontotemporal dementia (bvFTD), semantic dementia (SD), and progressive nonfluent aphasia (PNFA). This study was to investigate to what extent the pattern […]
Comparing registration methods for mapping brain change using tensor-based morphometry
Measures of brain changes can be computed from sequential MRI scans, providing valuable information on disease progression for neuroscientific studies and clinical trials. Tensor-based morphometry (TBM) creates maps of these brain changes, visualizing the 3D profile and rates of tissue growth or atrophy. In this paper, we examine the power of different nonrigid registration models […]
Adaptive cognitive testing in cerebrovascular disease and vascular dementia
Wouters, Hans,
de Koning, Inge,
Zwinderman, Aeilko H.,
van Gool, Willem A.,
Schmand, Ben,
Buiter, Maarten,
Lindeboom, Robert
Background/aims: To examine whether brevity can be combined with precision in measuring global cognitive ability in patients with cerebrovascular disease (CVD) or vascular dementia (VaD). Longer tests (e.g. the CAMCOG) are precise but inefficient, whereas brief tests (e.g. the MMSE) are efficient but imprecise.; Methods: A simulated computerized adaptive testing (CAT) algorithm using existing CAMCOG […]
Detecting frontotemporal dysfunction in ALS: utility of the ALS Cognitive Behavioral Screen (ALS-CBS)
Woolley, Susan C.,
York, Michele K.,
Moore, Dan H.,
Strutt, Adriana M.,
Murphy, Jennifer,
Schulz, Paul E.,
Katz, Jonathan S.
Up to half of patients with ALS develop cognitive impairment during the course of the illness. Despite this, there is no simple tool for screening patients in the clinical setting. This study examines the sensitivity, specificity and accuracy of the ALS Cognitive Behavioral Screen (ALS-CBS). We administered the measure to 112 ALS patients, including 31 […]
The northwestern anagram test: measuring sentence production in primary progressive aphasia
Weintraub, S.,
Mesulam, M.-M.,
Wieneke, C.,
Rademaker, A.,
Rogalski, E. J.,
Thompson, C. K.
Primary progressive aphasia (PPA) is a clinical dementia syndrome with early symptoms of language dysfunction. Postmortem findings are varied and include Alzheimer disease and frontotemporal lobar degeneration (FTLD), both tauopathies and TAR DNA binding protein (TDP-43) proteinopathies. Clinical-pathological correlations in PPA are complex but the presence in the clinical profile of agrammatism has a high […]
Midlife cardiovascular risk factors and late cognitive impairment
Virta, Jyri J.,
Heikkilä, Kauko,
Perola, Markus,
Koskenvuo, Markku,
Räihä, Ismo,
Rinne, Juha O.,
Kaprio, Jaakko
Cardiovascular risk factors increase the risk of dementia in later life. The aims of the current study were to assess the effect of multiple midlife cardiovascular risk factors on the risk of cognitive impairment in later life, and to assess the validity of the previously suggested CAIDE Study risk score predicting dementia risk 20 years later. […]
Detection of disease-associated α-synuclein in the cerebrospinal fluid: a feasibility study

With the aim to evaluate the significance and reliability of detecting disease-specific α-synuclein in the cerebrospinal fluid (CSF) we developed an ELISA and bead-assay. We used a commercial antibody (5G4) that does not bind to the physiological monomeric form of α-synuclein, but is highly specific for the disease-associated forms, including high molecular weight fraction of […]
