What this trial studies

This project aims to evaluate the feasibility, acceptability, and efficacy of an attention training intervention called Attention Process Training (APT-3) for treating brain fog symptoms in individuals suffering from Long COVID. The study will assess whether this program can be effectively delivered virtually and whether it can improve cognitive function in participants. Previous evidence suggests that APT-3 is effective for individuals with acquired brain injuries, but its application for Long COVID brain fog is still under investigation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 who have a confirmed history of SARS-CoV-2 infection and are experiencing cognitive symptoms related to Long COVID.

Not a fit: Patients with pre-existing neurological conditions or severe depression may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve cognitive function and quality of life for patients experiencing brain fog due to Long COVID.

How similar studies have performed: While APT-3 has shown promise in treating attention deficits in acquired brain injuries, its efficacy for Long COVID brain fog is still being explored and is considered a novel approach.
