Clinical Manifestations.

Background: Post-COVID19 syndrome is characterized by signs and symptoms that occur within 3 months of the onset of COVID19 acute phase and last at least 2 months. In the past 3 years, cognitive impairment has frequently been associated with COVID19 with descriptions of attentional, executive, memory, and language disorders. Many studies have assessed these cognitive disturbances using online and telephone tests, often in isolated interviews on a cross-sectional design in high-income countries.

Clinical Manifestations.

Background: The Cognitive Domains and Functional Assessment Questionnaire (CDFAQ) assess cognitive and functional decline for Neurocognitive Disorders based on the DSM-5 criteria (1). It's accuracy to the Informant Questionnaire on Cognitive Decline in the Elderly - Long Version (IQCODE-LV) has been assessed (2), and was translated and validated into English. The informant version (CDFAQ-IV) assess: Complex Attention (CA), Executive Functions (EF), Learning and Memory (LM), Language (L), Perceptual-Motor (PM) and Social Cognition.

Clinical Manifestations.

Background: Alzheimer's disease (AD) is classically viewed as a predominantly amnestic syndrome, with other cognitive and neuropsychiatric symptoms (NPS) being non-integral associations. Emerging Evidence suggests that within typical AD, these symptoms are core features from the onset.

Methods: We employed K-modes clustering on 2483 cognitively impaired (CI) individuals (CDR ≥ 0.

Clinical Manifestations.

Background: The newly proposed criteria by the AA working group incorporates both biological and clinical stages to characterize the progression of AD. In this study, we aim to evaluate the agreement between these two complementary systems.

Methods: Using 188 participants from McGill TRIAD and 139 from the HEAD cohorts, we categorized participants into biological (0-4) and clinical (0-4) stages using amyloid PET, tau PET(MK-6240), and clinical measures as described by the working group.

Clinical Manifestations.

Background: Short screening tools designed to detect cognitive impairment are important for clinical and research. The Clinical Dementia Rating (CDR) is the main used categorization system, which classifies from no dementia, to questionable dementia/mild cognitive impairment (MCI) and three severities of dementia.

Objective: To conduct an accuracy analysis of different short screening tests to predict CDR scores on a cohort of a Memory Clinic.

Clinical Manifestations.

Background: Language is frequently affected in patients with sporadic amyotrophic lateral sclerosis (sALS), with reduced performance in naming, syntactic comprehension, grammatical expression, and orthographic processing. In a previous study, we demonstrated that the language profile of patients with familial type 8 ALS (ALS8), linked to p.P56S VAPB mutation, is similar to sALS.

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: Dementia and cognitive impairment, primarily linked to aging, are increasingly recognized as multifactorial conditions. Emerging research has pointed to early menopause as another potential risk factor. However, its relationship with cognitive impairment needs further investigation, especially in low- and middle-income countries.

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.

Stone Tool Use by Black-Horned Capuchin Monkeys (Sapajus nigritus cucullatus) in an Urban Park in Londrina, Brazil.

Tool use to crack open palm nuts has been observed extensively in some capuchin monkey species. However, for southern black-horned capuchin monkeys (Sapajus nigritus cucullatus), there is only one published record of stone tool use from the 1990s, from an urban park in Londrina, Brazil. In the present study, we returned to this urban park to systematically investigate the hammer-and-anvil sites used to crack nuts by this capuchin monkey population.
