Dementia after Three Months and One Year from Stroke: New Onset or Previous Cognitive Impairment?

OBJECTIVE: Stroke is an important risk factor for dementia, but the exact mechanism involved in cognitive decline remains unclear. METHODS: Patients were divided into 2 groups: poststroke dementia group (PSD) and poststroke nondementia group (PSND). Variables and neuroradiological hallmarks were compared between 2 groups at 3 months (114 subjects) and 1 year (105 subjects) after stroke. RESULTS: Older age (OR 1.11, 95% CI 1.0-1.2; P < .05), education (OR .6, 95% CI .4-.8; P < .05), prestroke IQCODE (Informant Questionnaire on Cognitive Decline in the Elderly; OR .78, 95% CI .1-5.9; P < .05), premorbid apathy (OR 2.03, 95% CI 1.1-3.7; P < .05), and medial temporal lobe atrophy (MTLA) (OR 6.14, 95% CI 1.4-26.2; P < .05) were independently associated with PSD at 3 months after a cerebrovascular event, whereas at 1-year follow-up older age (OR 1.1, 95% CI 1.0-1.2; P < .05), prestroke IQCODE (OR .05, 95% CI .0-.9; P < .05), MTLA (OR 1.3, 95% CI 1.0-1.6; P < .05), and APACHE II (Acute Physiology and Chronic Health Evaluation; OR .6, 95% CI .4-.9; P < .05) were independently associated with PSD. CONCLUSIONS: Acute cerebrovascular disease could not be the only one mechanism explaining PSD. Neurodegenerative pathology must be taken into account.

Diagnosis disclosure and advance care planning in Alzheimer disease: opinions of a sample of Italian citizens.

BACKGROUND AND AIMS: In current Alzheimer disease (AD) research there is growing asymmetry between the modest benefits of the currently available treatments, in contrast to the possibility to diagnose AD early in its natural history. This complex situation brings along a number of important ethical issues about diagnosis disclosure and end-of-life decisions that need to be addressed. The principal aim of the study was to investigate the attitudes towards disclosure of a diagnosis of AD and disposition towards completion of advance care planning, in a sample of Italian citizens. METHODS: A convenience sample of 1,111 Italian citizens recruited from a community hospital in Brescia were interviewed using a structured questionnaire with both yes/no and multiple choice format questions about AD. RESULTS: The majority of the sample (83 %) wanted disclosure for themselves. Women and caregivers were significantly less likely to agree that their hypothetically afflicted relative should be informed of a diagnosis of AD. The majority of the sample (81 %) was in favor of advance care planning completion, most of all younger participants and non-caregivers. Less than a third of the sample (24 %) was aware of the existence a judicially appointed guardian for patients affected by dementia. CONCLUSION: The majority of the participants wanted a potential diagnosis of AD to be disclosed to them and to their relatives if they were to be afflicted. The utility of completion of advance care planning and designation of a judicially appointed guardian is frequently endorsed by the sample.

Amoebic colitis and liver abscess: A rare case of autochthonous invasive infection due to Entamoeba histolytica.

We report an unusual and confirmed case of invasive amebiasis in a non-endemic area where the source of infection remains unknown. During her admission, the patient developed amebic colitis and extraintestinal liver abscess with a favorable outcome following the antiparasitic therapy.

The impact of cognitive deficit on self-reported car crashes in ultra-octogenarian population: data of an Italian population-based study.

OBJECTIVE: To examine the usefulness of specific neurocognitive tests for predicting the crash involvement in ultra-octogenarian population. METHODS: A total of 800 subjects (mean age 82.4 + 3.1 years) underwent a battery of neuropsychological tests. Global intellectual functioning was assessed using the Mini Mental State Examination, mental flexibility and information processing speed were assessed using the Trail Making Test parts A and B (TMT-A and TMT-B), long-term memory was evaluated with the short story, and visuo-spatial skills were tested with Clock Drawing Test. One year after this evaluation, 343 (43%) participants have been interviewed by a telephone call to know if they were currently driving and if they had a car crash during this period. RESULTS: Two hundred ninety-seven subjects had their driving license renewed and completed the follow-up 1 year after. Data shows that less than 11% of this group had a car crash during the first year of observation (Crash Involved). Older subjects involved in a car crash showed significant worse performances on TMT-B (TMT-B pathological Crash Involved vs. Noncrash Involved 47% vs. 27%; p = 0.02) and on short story (short story pathological Crash Involved vs. Noncrash Involved 19% vs. 5%; p = 0.02). CONCLUSIONS: Trail Making test B and short story have been demonstrated to provide a predictive value of driving performance of older people. Therefore, we suggest that a simple and standardized battery of neuropsychological tests, lasting about 30 min and administered by an experienced staff, is a good diagnostic instrument for risk prevention of driving activity of older drivers.

COVID-19 vaccine uptake among family caregivers of people with dementia: The role of attitudes toward vaccination, perceived social support and personality traits.

People with dementia have an increased risk of contracting severe forms of COVID-19. Although in worldwide vaccination programs priority has been given to older people, having taken the vaccine does not totally eliminate the risk of contracting COVID-19 when one is in close contact with unvaccinated people. Thus, family caregivers' choices to remain unvaccinated against COVID-19 could have potentially lethal consequences for their relatives. To our knowledge, this study represents the first attempt within the international literature to analyze COVID-19 vaccine uptake among family caregivers of people with dementia and to identify some of the psychological factors, related to COVID-19 and vaccination behavior, that could facilitate or hinder vaccine uptake. Contact information for family caregivers was obtained from five different centers and associations throughout the Italian territory. Data were collected from 179 respondents during July-September 2021 using a cross-sectional web-based survey design. More than 75% of the respondents indicated that had been vaccinated against COVID-19 and reported receiving vaccine information mainly from print or electronic newspapers (86%), followed by TV (81%) and families (64.2%). In multivariable logistic regression analyses, worries about unforeseen future effects was significantly related to COVID-19 vaccine uptake, indicating that family caregivers concerned about potential side effects of vaccines were less likely to have been vaccinated against COVID-19 (OR = 0.60, CI = 0.40-0.89). Openness to experience was also related to COVID-19 vaccine uptake, with family caregivers higher on this trait being less likely to have been vaccinated against COVID-19 (OR = 0.83, CI = 0.71-0.98). Implications for targeting of vaccine-related messages are discussed.
