Cognitive symptoms after COVID-19.

Area of Science:

• Neurology
• Infectious Diseases
• Cognitive Science

Background:

• SARS-CoV-2 infection frequently leads to neurological symptoms, with cognitive alterations being particularly common.
• These cognitive changes can persist beyond the acute phase of infection, impacting patients long-term.

Purpose of the Study:

• To review the literature on post-COVID-19 cognitive symptoms.
• To highlight the unique characteristics and challenges associated with cognitive impairment after SARS-CoV-2 infection.

Main Methods:

• A narrative review of existing literature was conducted.

Main Results:

• Cognitive symptoms are prevalent in hospitalized and critically ill patients but also occur in mild COVID-19 cases, presenting atypical features.
• Post-COVID-19 cognitive issues may be prolonged, affect younger individuals more frequently, and share similarities with chronic fatigue syndrome.
• Current screening tests have suboptimal performance, necessitating standardized diagnostic criteria for cognitive impairment.

Conclusions:

• Post-COVID-19 cognitive impairment significantly affects quality of life and functional independence.
• Neuropsychological evaluation is crucial for diagnosis, severity assessment, and prognosis.
• Individualized treatment plans, potentially including cognitive stimulation, are needed.
