March 27, 2026 updated by: Shira Cohen-Zimerman, Shirley Ryan AbilityLab

Intensive Attention Training to Treat Brain Fog in Individuals With Long-Covid

This study is to find out if the Attention Processing Training program is a potential treatment for brain fog symptoms, reported by people with Long-Covid. Also investigating the feasibility of completing this program virtually.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The goal of this project is to test the feasibility, acceptability and efficacy of an attention training intervention (Attention Process Training; APT-3) as a potential treatment for brain fog symptoms experienced by people with Long-Covid. There already is good empirical evidence to support the idea that the APT-3 treatment is feasible and effective in improving attention in people with acquired brain injuries, but information about its efficacy and acceptability in people with Long-Covid brain fog is lacking.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Continuation or development of Long-Covid brain fog 3 months after the initial SARS-CoV-2 infection, with these symptoms lasting for at least 2 months with no other explanation.
  • Objective attentional deficits as measured by the Conners CPT-312, and/or the Digit Span subtest (WAIS- III13).

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Attention Training
The computer based APT-3 intervention will be delivered in a hybrid model that will combine in-person therapy sessions at Shirley Ryan AbilityLab and practice sessions which will be completed remotely. The dosing of each intervention training will be 30 minutes per day, 5 days a week, for 4 weeks (10 hours total over 4 weeks). The difficulty of the tasks in both interventions will increase progressively as the participants improve in their skills. APT-3 treatment will be administered by a trained and certified speech-language pathologist.
Other: Attention Training
The APT-3 is an evidence-based, standardized computer-based training program that was designed to improve attention skills that underlie higher level cognitive processes (e.g., executive functions and memory).
Other Names:
  • APT-3
Experimental: Music Program
This group will receive an enhanced music experience. They will listen to pre determined music for 30 minutes per day, 5 days a week, for 4 weeks (10 hours total over 4 weeks). This will be delivered in a hybrid model that will combine, in person, remote, and independent sessions, similar to the Attention Training group. Once they complete the music program, they will have the option to complete the Attention Training.
Other: Music Group
This group will listen to a pre-determined playlist of music following the same dosing as the attention training group as stated in the arms.
No Intervention: Delayed Attention Training
This group will not be provided any program for the initial 4 weeks. After they complete the week 5 assessments, they will have the option to complete the Attention Training.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of participants who successfully completed at least 80% of the study tasks sessions
Time Frame: 2 years
Recording the number of participants who completed at least 80% of the study sessions out of the number of all participants who enrolled in the study.
2 years

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment.
