Through Thick and Thin : The Meaning of Dementia for the Intimacy of Ageing Couples
2022
As the population ages, the number of people with dementia increases. An emerging body of research is focusing on living with dementia and understanding the experience of caring and the care burden. There is much less research on the meaning of dementia from the perspective of an older couple’s spousal relationship and related intimacy. This qualitative study explores the meanings of emotional and physical intimacy and the changes brought by dementia in the couplehood of persons with dementia and their spousal carers. The data comprise semi-structured interviews with 35 persons. The interviews were analysed using inductive qualitative content analysis. Four themes describing the meanings of…
Accuracy of the clinical diagnosis of dementia with Lewy bodies (DLB) among the Italian Dementia Centers: a study by the Italian DLB study group (DLB…
2022
Introduction: Dementia with Lewy bodies (DLB) may represent a diagnostic challenge, since its clinical picture overlaps with other dementia. Two toolkits have been developed to aid the clinician to diagnose DLB: the Lewy Body Composite Risk Score (LBCRS) and the Assessment Toolkit for DLB (AT-DLB). We aim to evaluate the reliability of these two questionnaires, and their ability to enhance the interpretation of the international consensus diagnostic criteria. Methods: LBCRS and AT-DLB were distributed to 135 Italian Neurological Centers for Cognitive Decline and Dementia (CDCDs), with the indication to administer them to all patients with dementia referred within the subsequent 3 months. We…
DCTN1 mutation analysis in Italian patients with PSP, MSA, and DLB
2020
Abstract DCTN1 encodes the largest subunit of dynactin complex essential in the retrograde axonal transport and cytoplasmic transport of vesicles; mutations in DCTN1 have been reported predominantly in individuals with Perry syndrome and, recently, in patients with progressive supranuclear palsy. Our genetic screening of DCTN1 in 79 patients with progressive supranuclear palsy, 100 patients with multiple system atrophy, and 28 patients with dementia with Lewy bodies from Italy revealed only synonymous and intronic variants, suggesting that DCTN1 mutations do not have a key role in the development of atypical parkinsonism in the Italian population.
Survival time and differences between dementia with Lewy bodies and Alzheimer’s disease following diagnosis: a meta-analysis of longitudinal studies.
2019
Objective: To synthesize the evidence across longitudinal studies comparing survival in dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Methods: We conducted a systematic review and meta-analysis of studies comparing survival in clinically diagnosed DLB to AD. Longitudinal cohort studies were identified through a systematic search of major electronic databases from inception to May 2018. A random effects meta-analysis was performed to calculate survival time and relative risk of death. Results: Overall, 11 studies were identified including 22,952 patients with dementia: 2029 with DLB (mean diagnosis age 76.3; 47% female) compared with 20,923 with AD (mean diagnosis age 77.2; 6…
Neuropsychiatric symptoms in 921 elderly subjects with dementia: a comparison between vascular and neurodegenerative types.
2008
Objective: i) to describe the neuropsychiatric profile of elderly subjects with dementia by comparing vascular (VaD) and degenerative dementias, i.e. dementia with Lewy bodies (DLB) and Alzheimer’s disease (AD); ii) to assess whether the severity and type of dementia are associated with clinically relevant neuropsychiatric symptoms (CR-NPS). Method: One hundred and thirty-one out-patients with VaD, 100 with DLB and 690 with AD were studied. NPS were evaluated by the neuropsychiatric inventory (NPI). Results: Vascular dementia had lower total and domain-specific NPI scores and a lower frequency of CR-NPS than AD and DLB, for which frequency of CR-NPS increased significantly with disease s…
Nasal chemosensory tests: biomarker between dementia with Lewy bodies and Parkinson disease dementia.
2020
BACKGROUND: Dementia with Lewy bodies (DLB) and Parkinson disease dementia (PDD) are progressive and disabling neurodegenerative disorders, which are often misdiagnosed due to theirs overlapping clinical and paraclinical features. Nevertheless, their adequate management requires an accurate differential diagnosis. The main aim of this study was to investigate the usefulness of olfactory and trigeminal nasal testing for the differential diagnosis between DLB and PDD. METHODS: Odor thresholds to three odorants differentially activating the olfactory and trigeminal systems were assessed in patients with DLB, PDD and healthy controls (n = 20 per group). RESULTS: Odor thresholds were significant…
Analysis of the LRP10 gene in patients with Parkinson's disease and dementia with Lewy bodies from Southern Italy
2020
Recently, the LRP10 gene has been associated with Parkinson's disease (PD), Parkinson's disease with dementia (PDD), and dementia with Lewy bodies (DLB). The aim of the present study was to evaluate the presence of mutations of the LRP10 gene in patients with PD or DLB from Southern Italy. Sequencing analysis revealed only 2 missense and 3 synonymous variants in patients and control subjects and a rare variant p.L622F in a PD case. These results suggest that LRP10 mutations are not a frequent cause of PD and DLB in Southern Italy.
Presence phenomena in parkinsonian disorders: Phenomenology and neuropsychological correlates.
2020
Introduction The feeling of a presence that occurs in the absence of objectively identifiable stimuli is common in parkinsonian disorders. Although previously considered benign and insignificant, recent evidence suggests that presence phenomena may act as the gateway to more severe hallucinations and dementia. Despite this, we still know relatively little about these phenomena. Objective To examine parkinsonian disorder patients' subjective experience of presence phenomena, and retrospectively analyse their cognitive correlates, in order to elucidate the emergence of information processing deficits in parkinsonian disorders. Methods/design 25 patients who endorsed presence phenomena were as…
Recognition by familiarity is preserved in Parkinson's without dementia and Lewy-Body disease.
2010
Objective The retrieval deficit hypothesis states that the lack of deficit in recognition often observed in patients with Parkinson's disease is because of the low retrieval requirements of the task, given that these patients have retrieval and not encoding deficits. To test this hypothesis we investigated recognition memory by familiarity in Parkinson's patients and in patients with Lewy Bodies disease and Parkinson with dementia. Method We analyzed to what extent the experimental groups were able to recognize by familiarity in a typical yes/no recognition memory task. The experimental groups were patients with early nondemented Parkinson's disease, advanced nondemented Parkinson's disease…
The Italian dementia with Lewy bodies study group (DLB-SINdem): toward a standardization of clinical procedures and multicenter cohort studies design
2017
Dementia with Lewy bodies (DLB) causes elevated outlays for the National Health Systems due to high institutionalization rate and patients' reduced quality of life and high mortality. Furthermore, DLB is often misdiagnosed as Alzheimer's disease. These data motivate harmonized multicenter longitudinal cohort studies to improve clinical management and therapy monitoring. The Italian DLB study group of the Italian Neurological Society for dementia (SINdem) developed and emailed a semi-structured questionnaire to 572 national dementia centers (from primary to tertiary) to prepare an Italian large longitudinal cohort. The questionnaire surveyed: (1) prevalence and incidence of DLB; (2) clinical…
