[Long COVID : which neuropsychological intervention ? The example applied at the Leenaards Memory Centre]. / Covid Long : quelle prise en charge neuropsychologique ? La filière proposée au Centre Leenaards de la Mémoire.

A "Long COVID" care management was created at the Leenaards Memory Centre (Lausanne University Hospital) to meet the high demand for neuropsychological examinations in the patients which have persistent symptoms for several months. A multidisciplinary evaluation specifically addressing aspects of fatigue and sleep as well as cognition has been developed to receive these patients. Depending on the severity of their symptoms, they are then oriented towards a holistic group treatment, integrating cognitive remediation including psycho-education, restorative and compensatory methods to cope with their cognitive difficulties, and tools to manage the various symptoms of COVID-long (fatigue, insomnia, stress, depression and reduced quality of life).

Une filière « Covid long ¼ a vu le jour au Centre Leenaards de la mémoire du CHUV pour répondre à une importante demande d'examens neuropsychologiques chez des patients aux symptômes persistant depuis plusieurs mois. Les patients bénéficient d'une évaluation multidisciplinaire qui inclut les aspects de la fatigue et du sommeil ainsi que la cognition. Ils sont ensuite orientés, selon la sévérité de leurs symptômes, vers une prise en charge groupale holistique qui intègre de la remédiation cognitive incluant de la psychoéducation, des méthodes restauratives et compensatoires pour faire face à leurs difficultés cognitives et des outils permettant de gérer les différents symptômes caractéristiques d'un Covid long (fatigue, insomnie, stress, dépression et diminution de la qualité de vie).

Emotional pre-eminence of human vocalizations.

Human vocalizations (HV), as well as environmental sounds, convey a wide range of information, including emotional expressions. The latter have been relatively rarely investigated, and, in particular, it is unclear if duration-controlled non-linguistic HV sequences can reliably convey both positive and negative emotional information. The aims of the present psychophysical study were: (i) to generate a battery of duration-controlled and acoustically controlled extreme valence stimuli, and (ii) to compare the emotional impact of HV with that of other environmental sounds. A set of 144 HV and other environmental sounds was selected to cover emotionally positive, negative, and neutral values. Sequences of 2 s duration were rated on Likert scales by 16 listeners along three emotional dimensions (arousal, intensity, and valence) and two non-emotional dimensions (confidence in identifying the sound source and perceived loudness). The 2 s stimuli were reliably perceived as emotionally positive, negative or neutral. We observed a linear relationship between intensity and arousal ratings and a "boomerang-shaped" intensity-valence distribution, as previously reported for longer, duration-variable stimuli. In addition, the emotional intensity ratings for HV were higher than for other environmental sounds, suggesting that HV constitute a characteristic class of emotional auditory stimuli. In addition, emotionally positive HV were more readily identified than other sounds, and emotionally negative stimuli, irrespective of their source, were perceived as louder than their positive and neutral counterparts. In conclusion, HV are a distinct emotional category of environmental sounds and they retain this emotional pre-eminence even when presented for brief periods.
