Left neglect dyslexia: Perseveration and reading error types.

Right-brain-damaged patients may show a reading disorder termed neglect dyslexia. Patients with left neglect dyslexia omit letters on the left-hand-side (the beginning, when reading left-to-right) part of the letter string, substitute them with other letters, and add letters to the left of the string. The aim of this study was to investigate the pattern of association, if any, between error types in patients with left neglect dyslexia and recurrent perseveration (a productive visuo-motor deficit characterized by addition of marks) in target cancellation.

(Un)awareness of unilateral spatial neglect: a quantitative evaluation of performance in visuo-spatial tasks.

Right-brain-damaged patients with unilateral spatial neglect are usually unaware (anosognosic) about their spatial deficits. However, in the scientific literature there is a lack of systematic and quantitative evaluation of this kind of unawareness, despite the negative impact of anosognosia on rehabilitation programs. This study investigated anosognosia for neglect-related impairments at different clinical tasks, by means of a quantitative assessment.

Memantine in Alzheimer's disease: experience in an Alzheimer's disease assessment unit.

Background And Aims: Memantine is an uncompetitive N-methyl-D-aspartate receptor antagonist. Clinical and observational studies have demonstrated its efficacy on both cognitive and behavioral symptoms of moderate-to-severe Alzheimer's disease (AD) and described its good safety and tolerability profile. We report here our experience with memantine in patients with AD during a two-year follow-up.

Spatial neglect and perseveration in visuomotor exploration.

Objective: Right-brain-damaged patients with left spatial neglect make perseveration errors in target cancellation tasks. A recent study (Ronchi, Posteraro, Fortis, Bricolo, & Vallar, 2009) showed that perseveration occurred more frequently in star than in letter cancellation, possibly due to different stimulus disposition. In this study we investigated the role of the spatial organization of targets (scattered vs.

Caregiver burden and coping in early-stage Alzheimer disease.

This study was set out to describe caregiver-perceived burden and coping in early-stage Alzheimer disease (AD). A total of 163 consecutive pairs of patients with AD and their principal caregivers were initially recruited. The caregivers completed the Caregiver Burden Inventory (CBI) and the Coping Orientations to Problems Experienced scale, and also provided sociodemographic information; the patients with AD were assessed by means of the Mini Mental State Examination and the Neuropsychiatric Inventory.

Differences between physician and caregiver evaluations in Alzheimer's disease.

In Alzheimer's disease (AD) differences are often reported between caregivers' and physicians' aims and evaluations. The aim of this study was to investigate the presence of discrepancies between the evaluations of caregivers and physicians. Two hundred and eighteen caregivers of outpatients diagnosed with mild-to-moderate AD, referred to our Alzheimer's Disease Assessment Unit, entered the study.
