[Impairments in neurocognitive functions in patients with long COVID: A systematic review].

Background: Studies have shown impairments in neurocognitive functions which persist more than 3 months after COVID-19 (long COVID). It remains unclear what these impairments entail, how long they persist and what proportion of the patients exhibit them.

Aim: To define the specific neurocognitive profile and to determine the proportion of deficits in at least one cognitive domain in patients with long COVID.

Effort discounting and its association with negative symptoms in schizophrenia.

Introduction: Deficits in the initiation and persistence of goal-directed behaviour are key aspects of schizophrenia. In this study, the association between these motivational deficits and discounting of reward value in function of increasing physical effort costs was investigated.

Methods: Effort-based decision-making was investigated in 40 patients with a DSM-IV diagnosis of schizophrenia and 30 age- and sex-matched healthy control subjects by means of an effort discounting task.
