SARS-CoV-2 infection and cognition in community-dwelling and nursing home residents in southern Switzerland.

Background: COVID-19 patients can report 'brain fog' and may exhibit cognitive symptoms for months after recovery (Cognitive COVID). However, evidence on whether and the extent to which SARS-CoV-2 infection impacts cognition irrespective of COVID-19 course and severity is limited to clinical samples and mainly comes from prognostic studies. We aimed to explore the association between serologically confirmed SARS-CoV-2 infection and cognitive functioning in community-based and institutionalized older adults, irrespective of COVID-19 symptoms.

Associations of multilingualism and language proficiency with cognitive functioning: epidemiological evidence from the SwissDEM study in community dwelling older adults and long-term care residents.

Background: We explored whether number of languages spoken and language proficiency are associated with cognitive performance among older adults living in the community and in long-term care (LTC) in Switzerland.

Methods: Among study participants, 664 lived in the community in the Canton of Zurich (Mean age = 72.97 years; SD = 6.

Association between serologically confirmed COVID-19 infection and cognitive functioning in community dwelling older adults.

Introduction: COVID-19 infection can impact the central nervous system, and is often associated with cognitive decline. However, there are no studies linking serologically confirmed COVID-19 infection with objectively assessed cognitive functioning. We explored whether presence of SARS-CoV-2 antibodies account for variability in participants' scores on a neuropsychological assessment.

Transcranial Magnetic Stimulation Improves Executive Functioning through Modulation of Social Cognitive Networks in Patients with Mild Cognitive Impairment: Preliminary Results.

(1) Background: Patients with mild cognitive impairment (MCI) often present impairment in executive functions (EFs). This study aimed to investigate the effect of high-frequency repetitive transcranial magnetic stimulation (rTMS) on EFs in patients with MCI. (2) Methods: A prospective trial was conducted on 11 patients with MCI.

The role of disability and depressive symptoms in the relation between objective cognitive performance and subjective cognitive decline.

Background: Subjective cognitive decline (SCD) and subjective memory decline (SMD) are common among older people. Evidence linking SCD and SMD with cognitive and memory impairment is inconsistent. Moreover, little is known about the associations of SCD and SMD with disability.

Dementia is (not) a natural part of ageing: a cross-sectional study on dementia knowledge and misconceptions in Swiss and Italian young adults, adults, and older adults.

Background: Increasing public awareness and understanding of dementia is the second key action area of the 2017 WHO Global action plan on a public health response to dementia. To achieve this aim, the first indispensable step is to understand the average level of dementia knowledge and to identify areas of low dementia knowledge. We aimed to quantify dementia knowledge in the general population, and to explore the extent to which it differs by age, sex, education, and indirect experience with dementia.

Relationship between cognitive disturbances and sleep disorders in multiple sclerosis is modulated by psychiatric symptoms.

Background: Multiple sclerosis (MS) patients with cognitive impairment (CI) frequently suffer from sleep disturbances and emotional symptoms. The aim of this study was to investigate the relationship between CI and sleep disturbances and the role of anxiety and depression on this relationship in MS patients.

Methods: Prospective cross-sectional study including 80 MS patients that underwent neurologic, cognitive, psychiatric assessment, and polysomnographic registration.
