Background: People with dementia and their family caregivers may face a great burden through social isolation due to the COVID-19 pandemic, which can be manifested as various behavioral and clinical symptoms. Objective: To investigate the impacts of social isolation due to the COVID-19 pandemic on individuals with dementia and their family caregivers. Methods: Two semi-structured questionnaires were applied via telephone to family caregivers of people diagnosed with dementia in three cities in Argentina, Brazil, and Chile, in order to assess clinical and behavioral changes in people with dementia and in their caregivers. Results: In general, 321 interviews were conducted. A significant decline in memory function has been reported among 53.0%of people with dementia. In addition, 31.2%of individuals with dementia felt sadder and 37.4%had increased anxiety symptoms. These symptoms of anxiety were greater in individuals with mild to moderate dementia, while symptoms of agitation were greater in individuals with severe dementia. Moreover, compulsive-obsessive behavior, hallucinations, increased forgetfulness, altered appetite, and increased difficulty in activities of daily living were reported more frequently among individuals with moderate to severe dementia. Caregivers reported feeling more tired and overwhelmed during this period and these symptoms were also influenced by the severity of dementia. Conclusion: Social isolation during the COVID-19 pandemic triggered a series of negative behavioral repercussions, both for people with dementia and for their family caregivers in these three South American countries.
Introduction Health systems in numerous countries around the world are suffering a serious burden as a consequence of the COVID-19 pandemic. As a result of this situation, the follow-up of such chronic diseases as dementia may be at risk. Similarly, neuropsychiatric complications related to lockdown measures may also be neglected; Argentina’s lockdown has been the longest implemented in Latin America. This study aims to determine the frequency of the different types of medical consultations for neurocognitive disorders and the predictors for requiring consultation since the beginning of the lockdown. Methods We performed a descriptive, observational, cross-sectional study based on data collected through an online survey. Results Data were collected on 324 participants, with 165 (50.9%) having had at least one medical consultation. Consultations were held by telephone in 109 cases (33.6%), by e-mail in 62 (19.1%), by video conference in 30 (9.3%), and at the emergency department in 23 (7.1%). Predictors of requiring consultation were Clinical Dementia Rating scores ≥1 ( P < .001) and diagnosis of Alzheimer disease ( P = .017). Higher Neuropsychiatric Inventory scores were found in the group of respondents who did require medical consultation ( P < .001), but no significant differences were found between groups for Zarit Burden Interview scores. Conclusion We identified a high prevalence of behavioural disorders and caregiver burden during lockdown. Nevertheless, only 50% of respondents had sought medical consultation (by telephone or email in 52.7% of cases). Care of people with dementia must be emphasised, guaranteeing follow-up of these patients.
Introducción Varios países del mundo padecen una grave carga en sus sistemas de salud como consecuencia de la pandemia por COVID-19. Esta realidad pone en riesgo el seguimiento de patologías crónicas como las demencias. Asimismo, la atención de las posibles complicaciones neuropsiquiátricas relacionadas con el aislamiento preventivo de la población (cuarentena), que en el caso de Argentina se considera la más prolongada de Latinoamérica. El objetivo del presente trabajo es determinar la frecuencia de las distintas modalidades de consulta médica en relación con la patología neurocognitiva del paciente y las variables predictoras de consulta desde el inicio de la cuarentena. Métodos Estudio descriptivo observacional y transversal basado en la recolección de datos a través de una encuesta. Resultados Hubo 324 participantes, 165 (50,9%) de los cuales realizaron al menos una consulta médica. Frecuencia de modalidades de consulta: teléfono, 109 (33,6%); correo electrónico, 62 (19,1%); videoconsulta, 30 (9,3%); servicio de emergencias, 23 (7,1%). Predictores de consulta: Clinical Dementia Rating ≥ 1 (p < 0,001); diagnóstico: Alzheimer (p = 0,017). Se encontraron puntajes más altos del Inventario Neuropsiquiátrico (NPI) en el grupo que ha realizado consultas médicas (p < 0,001). Dicha diferencia no fue observada en el puntaje de la escala de carga del cuidador (Zarit). Conclusión Evidenciamos alta prevalencia de trastornos conductuales en pacientes y de sobrecarga en cuidadores durante la cuarentena. Solamente el 50% accedió a una consulta médica (52,7% por modalidad telefónica y correo electrónico). Es necesario extremar los cuidados en personas con demencia, garantizando el seguimiento de su patología.
ABSTRACT. The 12-item version of the Boston Naming Test (BNT) was adapted to Argentina for the detection of dementia due to Alzheimer's disease (AD), with scores similar to the original 60-item version (sensitivity and specificity of 85 and 94%, respectively) without demographic influence (age and educational level). To date, no publications on the use of abbreviated BNT in other degenerative pathologies with language impairment have been reported. Objective: The objective of this study was to evaluate the usefulness of 12-item BNT in primary progressive aphasia (PPA), the behavioral variant of frontotemporal dementia (FTDbv), and AD. Methods: Notably, 47 patients with probable AD (NIA-AA 2011) — clinical dementia rating (CDR) 0.5–1, 55 with FTDbv, 17 with PPA, and 46 controls were evaluated and matched for age and education. Exclusion criteria were as follows: alcoholism, other previous neurological or psychiatric illnesses, and education <4 years. All were assessed with a full neuropsychological battery and a 12-item version of BNT. Results: Median scores of 12-item BNT were as follows: PPA: 3.87 (SD=2.99), AD: 6.13 (SD=3.03); FTDbv: 8.41 (SD=2.53); and controls: 10.22 (SD=1.82). Receiver Operating Characteristic (ROC) curves were plotted. Conclusions: The 12-item version of BNT can be useful, simple, and fast to identify and differentiate PPA, FTDbv, and AD from controls while retaining the discriminative ability of the original version.
