COVID-19 pandemic in Argentina has affected the care of older adults with dementia deeply. Our objective was to study how the obligatory social isolation affected stress caregiver and burden of care of family members of subjects living with dementia in the community after the initial 4 weeks of quarantine in our setting. We did a questionnaire survey among 80 family caregivers of persons with Alzheimer’s disease (AD) or related dementia collected on April 2020. We designed a visual analog scale to test the level of the burden of care. Characteristics of people with dementia and their caregivers were analyzed with descriptive (mean, standard deviation, frequency and percent) and inferential statistics (chi-square test). The sample included older adults (mean age: 80.51 ± 7.65) with different stages of dementia. Family was the primary provider of care in 65%. Overall, COVID-19 confinement increased stress caregiver independently of the dementia stage, but those caring for severe cases had more stress compared to milder forms of the disease. Other findings were that half of the subjects with dementia experienced increased anxiety and that most family members discontinued all sort of cognitive and physical therapies. Family members’ main concerns were for severe dementia cases, fear of absence of the paid caregiver during the epidemic, and for mild cases fear of spreading the disease while assisting patients with instrumental activities. A partnership between departments of public health, care workers and families must be planned to guarantee continuity of care during these unique COVID-19 times.

necessary to develop a plan of action to help dementia subjects deal with the increased stress that this epidemic imposed on them.

As life expectancy increases, there is a marked increase in the elderly population eager to continue driving. A large proportion of these elderly drive safely, however, patients with mild dementia are high-risk drivers. Objective: to identify the cognitive tests that best predict driving ability in subjects with mild dementia. Methods: 28 drivers with mild dementia and 28 healthy elderly subjects underwent an extensive cognitive assessment (NACC Uniform Data Set Neuropsychological Battery), completed an adapted On Road Driving Test (ORDT) and a Driving Simulator assessment. Results: drivers with mild dementia made more mistakes on the ORDT and had slower responses in the simulator tasks. Cognitive tests correlated strongly with on road and simulator driving performance. Age, the Digit Symbol Modalities Test and Boston Naming Test scores were the variables that best predicted performance on the ORDT and were included in a logistic regression model. Conclusion: the strong correlation between driving performance and performance on specific cognitive tests supports the importance of cognitive assessment as a useful tool for deciding whether patients with mild dementia can drive safely. The algorithm including these three variables could be used as a screening tool for the detection of unsafe driving in elderly subjects with cognitive decline.

Purpose To describe results of the Amyloid, Tau, Neurodegeneration (ATN) research framework classification in the Argentine‐Alzheimer's Disease Neuroimaging Initiative (arg‐ADNI) cohort. Methods Twenty‐three patients with mild cognitive impairment (MCI), 12 dementia of Alzheimer's type (DAT), and 14 normal controls were studied following the ADNI2 protocol. Patients were categorized according to presence or absence of the biomarkers for amyloid beta (Aβ; A: amyloid positron emission tomography [PET] scan or cerebrospinal fluid [CSF] Aβ42), tau (T: CSF phosphorylated‐tau), and neurodegeneration (N: CSF total‐tau, fluorodeoxyglucose [FDG]‐PET scan, or structural magnetic resonance imaging [MRI] scan). Results A+T+N+ biomarker profile was identified at baseline in 91% of mild dementia patients, 20% of early MCI patients, 46% of late MCI patients, and 14% of control subjects. Suspected non‐AD pathophysiology (SNAP, A‐T‐N+) was found in 8% of mild dementia, 20% of early MCI, 15% of late MCI, and 7% of control subjects. Conversion rates to dementia after 5‐year follow‐up were 85% in A+T+N+ MCI patients and 50% in A‐T‐N+ patients. Conclusions We present initial 5‐year follow‐up results of a regional ADNI based on AD biomarkers and the ATN classification.
