Tumor region associated with specific processing speed outcomes [PDF]
Pediatric Blood & Cancer, 2023 AbstractObjectiveProcessing speed (PS) is a vulnerable cognitive skill in pediatric cancer survivors as a consequence of treatments and, less consistently, tumor region. Studies conventionally examine graphomotor PS; emerging research suggests other aspects of PS may be impacted.
