Long Neurocognitive and Neuropsychiatric Sequelae in Participants with Post-COVID-19 Infection: A Longitudinal Study.

Objective: To evaluate and characterize the cognitive changes in COVID-19 participants at 6-month follow-up, and to explore a possible association with clinical symptoms, emotional disturbance and disease severity.

Methods: This single-center longitudinal cohort study included participants aged 20 and 60 years old to exclude cognitive impairment age-associated with confirmed COVID-19 infection. The initial evaluation occurred 10 to 30 days after hospital or ambulatory discharge, with a subsequent follow-up at 6 months.

Neurocognitive and Neuropsychiatric Sequelae in Long COVID-19 Infection.

: To characterize the cognitive profile of long COVID-19 subjects and its possible association with clinical symptoms, emotional disturbance, biomarkers, and disease severity. : We performed a single-center cross-sectional cohort study. Subjects between 20 and 60 years old with confirmed COVID-19 infection were included.

Impact of COVID-19 infection on cognition and its association with neurological symptoms.

Objective: To characterize the cognitive profile following COVID-19 infection and its possible association to clinical symptoms, emotional disturbance, biomarkers, and disease severity.

Methods: This was a single-center cross-sectional cohort study. Subjects between 20- and 60-year old with confirmed COVID-19 infection were included.

Ikos Test: New Tool for the Assessment of Semantic Knowledge in Early Alzheimer Disease.

Background: Semantic memory (SM) constitutes a cognitive system that is seriously affected by Alzheimer's disease (AD). There are several tests for assessing SM, but a tool is needed to assess AD in the early stages of the illness.

Objective: The study aimed to create, validate, and normalize a new test to assess SM, called the Ikos test, for AD and early AD in clinical practice.

In-Out-Test: A New Paradigm for Sorting the Wheat from the Chaff in Prodromal Alzheimer's Disease.

Background: Assessment of hippocampal amnesia is helpful to distinguish between normal cognition and mild cognitive impairment (MCI), but not for identifying converters to dementia. Here biomarkers are useful but novel neuropsychological approaches are needed in their absence. The In-out-test assesses episodic memory using a new paradigm hypothesized to avoid reliance on executive function, which may compensate for damaged memory networks.
