Purpose: The loss of olfactory function is known to occur in patients suffering from (behavioral variant) frontotemporal dementia ((bv)FTD) and Alzheimer's disease (AD), although different pathophysiological mechanisms underpin this clinical symptom in both disorders. This study assessed whether brain metabolism of the olfactory circuit as assessed by positron emission tomography (PET) imaging with 2-[fluorine-18]fluoro-2-deoxy-d-glucose ([F]-FDG) can distinguish these entities in different subsets of patients.

Methods: Patients presenting with cognitive decline were included from a prospectively kept database: (1) bvFTD patients, (2) AD patients and (3) patients with logopenic primary progressive aphasia (PPA).

Background: Different 3D-printed materials polyactic acid (PLA), polyamide (PA), polycarbonates (PC), acrylonitrile butadiene styrene (ABS) and GreenTEC Pro® have been considered for surgical templates, but there is a sparity of data about how these materials are affected by steam sterilization. The aim of the current study was to test if and how these materials change morphologically when high temperature, pressure and humidity are applied during the steam sterilization process. The overall aim is to create patient-specific sawing templates for performing corrective osteotomies.

A 61-year-old woman with suspected schizophrenia has been attending an outpatient geriatrics service for some time, initially with memory complaints and panic attacks. During treatment, the diagnosis schizophrenia was rejected and psychopharmaceuticals were largely phased out, which improved cognitive functions. Eventually, flashbacks of incest experienced in childhood remained together with REM sleep pathology.

This study examined the utility of the recently published MMSE-2:SV in detecting cognitive impairment. We used receiver operating characteristics to test the discriminative power of the MMSE-2:SV for distinguishing between older adults without mild cognitive impairment (MCI) or dementia (n=67) and patients with MCI (n=76) or dementia (n=79). The results show that the MMSE-2:SV had excellent discriminative ability in distinguishing older controls from patients with dementia, with cut-off scores of 26 and 27 (max=30) yielding appropriate sensitivity (0.

Background: The seasonal influenza epidemic poses a significant burden on hospitals, both in terms of capacity and costs. Beds that are occupied by isolated influenza patients result in hospitals temporary being closed to admissions and elective operations being cancelled. Improving hospital and emergency department (ED) patient flow during the influenza season could solve these problems.

Cognitive training has been shown to result in improved behavioral performance in normal aging and mild cognitive impairment (MCI), yet little is known about the neural correlates of cognitive plasticity, or about individual differences in responsiveness to cognitive training. In this study, 21 healthy older adults and 14 patients with MCI received five weeks of adaptive computerized working-memory (WM) training. Before and after training, functional Near-Infrared Spectroscopy (fNIRS) was used to assess the hemodynamic response in left and right prefrontal cortex during performance of a verbal n-back task with varying levels of WM load.

Working memory (WM) is one of the cognitive functions that is susceptible to ageing-related decline. Interventions that are able to improve WM functioning at older age are thus highly relevant. In this pilot study, we explored the transfer effects of core WM training on the WM domain and other cognitive domains in 23 healthy older adults and 18 patients with amnestic mild cognitive impairment (MCI).

A multidisciplinary workgroup has revised the 2004 practice guidelines on 'Delirium' on the initiative of the Dutch Geriatrics Society. In comparison with the previous version, the new guidelines place more emphasis on screening and non-pharmaceutical prevention and treatment. They recommend a degree of restraint when prescribing medication.

The revised practice guideline 'Delirium' of the Dutch College of General Practitioners (NHG) provides recommendations about the prevention, early detection, diagnosis and treatment of delirium in elderly patients in general practice. The guideline now also offers tools for the treatment of delirium in terminally-ill patients. A patient with delirium can only be cared for at home if a safe environment and the continuous presence of carers can be guaranteed.

Dementia with Lewy Bodies (DLB) is a well-described clinical entity. DLB patients can be treated with acetylcholinesterase inhibitors (AChEI's). However, should we also treat patients who have but part of the symptoms and who are currently described as MCI-DLB? Will these MCI-DLB patients benefit from AChEI's in terms of direct effect on cognition and behaviour and final outcome? Two cases are presented to demonstrate the clinical features of MCI-DLB and the effect of treatment with rivastigmine (AChEI).
