Clinical Manifestations.

Background: Subjective cognitive decline (SCD) is defined by the presence of cognitive complaints in cognitively unimpaired (CU) individuals. Despite being part of the continuum of a neurodegenerative disease, the cause of the cognitive complaint is quite heterogeneous. Sleep disturbances may be associated with cognitive complaints and even objective cognitive decline.

Clinical Manifestations.

Background: Mild Behavioral Impairment (MBI) is a construct developed to capture neuropsychiatric symptoms in individuals in early stages of neurodegenerative diseases. The assessment of MBI in individuals with preclinical cognitive manifestations in Brazil is still quite limited. The aim of this study is to evaluate the MBI-Checklist (MBI-C) in individuals with subjective cognitive decline (SCD) and mild cognitive impairment (MCI) in the Brazilian Subjective Cognitive Decline (BRASCODE) cohort in southern Brazil.

Association of education with occurrence of delirium in patients from an emergency department.

Background: Delirium is a neuropsychiatric syndrome with multiple etiological factors. Evaluation of delirium in different settings, especially the Emergency Department (ED) pertaining to different regions of the world with patients from different cultural and educational backgrounds is needed.

Objective: To determine the prevalence of delirium and its association with education in an ED in Brazil during a 6-month period.
