What this trial studies

This study evaluates the feasibility of using home-based transcranial photobiomodulation (tPBM) combined with remote cognitive training to enhance cognitive performance in survivors of acute lymphoblastic leukemia (ALL) and Hodgkin's lymphoma (HL). Participants will be randomized to receive either active tPBM at alpha or gamma frequencies, or a sham treatment, three times a week for two months. The study aims to assess improvements in cognitive functions such as attention and memory, as well as self-reported symptoms related to executive dysfunction, sleep, and mood. The intervention targets specific brain networks associated with cognitive processing.

Who should consider this trial

Good fit: Ideal candidates are survivors of ALL or HL who are at least 18 years old, have completed treatment for at least two years, and exhibit signs of executive dysfunction.

Not a fit: Patients with major psychiatric conditions or those currently taking medications for neurocognitive impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve cognitive function and quality of life for childhood cancer survivors.

How similar studies have performed: While the use of tPBM is a novel approach in this context, similar studies have shown promise in improving cognitive function in other populations.

Inclusion Criteria:

* Completed treatment for acute lymphoblastic leukemia (ALL) or Hodgkin's Lymphoma (HL) at SJCRH.
* Enrolled in SJLIFE, and less than 21 years of age at diagnosis.
* 18 years of age or older at time of enrollment.
* 2 years or greater post-treatment completion of cancer directed therapy and not currently receiving any cancer directed therapy.
* English language proficiency.

* Executive dysfunction defined as having an age-adjusted standard score less than 16th percentile on objectively assessed cognitive test or patient-reported executive dysfunction defined as having a standard score greater than 84th percentile within 3 years of time of enrollment.

Exclusion Criteria:

* History of neurologic condition or genetic disorder associated with neurocognitive impairment unrelated to cancer diagnosis or treatment.
* Enrolled on another independent cognitive intervention protocol within the last year.
* Female participants who are pregnant or lactating (determined by participant self-report due to the remote nature of this study)
* Tattoo or artificial marking in the area where the device will be positioned.
