Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 21 and older who have been diagnosed with a hematologic malignancy and are experiencing mild to moderate cognitive impairment.

Probably not a fit

Patients with pre-existing neurological disorders, significant sensory impairments, or those who have participated in similar interventions recently may not benefit from this study.

What this trial studies

This clinical trial aims to evaluate the feasibility of a combined intervention program that includes a modified ketogenic diet and online cognitive training for survivors of hematologic malignancies. Participants will be randomized into two groups: one receiving the combined intervention for 12 weeks and a waitlist control group that will start the cognitive training after the wait period. The study will assess whether this intervention improves cognitive functioning compared to the control group and how long any effects may last. Safety and tolerability will be monitored throughout the trial.

Why it matters

Potential benefit: If successful, this intervention could enhance cognitive functioning in survivors of blood cancers, potentially improving their quality of life.

How similar studies have gone: While the combination of dietary interventions and cognitive training is innovative, similar approaches have shown promise in other populations, suggesting potential for success.
