Long-term Neurocognitive and Psychiatric Consequences in Severe COVID-19 Survivors.

Conditions
Neurocognitive Dysfunction
Covid19
Registration Number
NCT05019300
Lead Sponsor
Pontificia Universidad Catolica de Chile
Brief Summary

Long-term neurocognitive and psychiatric consequences of COVID-19 remain mostly unknown to date. It has been reported that coronaviruses cause direct central nervous system infection (Needham et al. 2020). Besides that, new or worsening cognitive impairment commonly occurs and persists in survivors of intensive care unit (ICU) stay (Hosey \& Needham. 2020). The purpose of our study is to search and describe the cognitive and psychiatric long-term consequences of COVID-19 on patients who have been discharged from critical care units. This is an ambidirectional cohort study, that attempts to follow adults discharged from critical Care Units Adults due to COVID-19 up to 12 months after discharge, to evaluate the presence of cognitive impairment, linguistic and phonation function, depression, fatigue, functional gastroenterological symptoms, anxiety, or post traumatic disorder, and performance in activities of daily living and physical response to exercise as well.

Min score: 0 Max score: 100 highest score means worst quality of life.

Setting: online

Neurological Soft Signs12 months

Test: Heidelberg Neurological Soft Signs Scale

16 items on five factors ("motor coordination": Ozeretzki's test, diadochokinesis, pronation/supination, finger-to-thumb opposition, speech and articulation; "sensory integration": gait, tandem walking, two-point discrimination; "complex motor tasks": finger-to-nose test, fist-edge-palm test; "right/left and spatial orientation": right/left orientation, graphesthesia, face-hand test, stereognosis; "hard signs": arm holding test, mirror movements). All items except for gait, tandem gait, Ozeretzki's test, speech and articulation and right/left orientation are assessed separately for both, right and left sites respectively. Ratings are given on a 0-3 point scale (no/slight/moderate/marked abnormality).

Higher scores mean worse outcomes. Min score: 0 Max score: 48 No cut-off point established in the literature.

Scales: Scales for outcomes in Parkinson's dysfunction-autonomic (SCOPA-AUT), Orthostatic hypotension symptom assessment (OHSA) and Orthostatic hypotension activity scale (OHACT).

Setting: online

Fatigue12 months

Measured by the Modified fatigue impact scale (MFIS). The MFIS is a modified version of the 40-item Fatigue Impact Scale (FIS), which was originally developed to assess the effects of fatigue on quality of life in patients with chronic diseases. The FIS has patients rate the extent to which fatigue has affected their life in the past 4 weeks on a questionnaire consisting of 10 "physical" items, 10 "cognitive" items, and 20 "social" items, with 0 indicating "no problem" and 4 indicating "extreme problem."

The cut-off point suggested is of ≥38 Min score: 0 Max score: 160

Setting: online

Post-Covid-19 functional scale 5 levels of severity, where o is non impairment and 5 is the highest level of impairment.

Setting: online

Anxiety12 months

Test: Generalized Anxiety Disorder-7 score
