Cognitive impairment in HSCT recipients

There was no significant difference in the prevalence of global cognitive deficit between RIC allo-HSCT recipients and controls before HSCT (17.2% for both; P=1.0), at 6 months (22.0% vs 16.5%; P=0.35), 1 year (24.1% vs 19.5%; P=0.46), or 2 years (30.6% vs 16.4%; P=0.05) after HSCT.

However, the prevalence was significantly higher for RIC allo-HSCT recipients 3 years after HSCT (35.4% vs 8.7%; P=0.0012).

There was no significant difference in the prevalence of global cognitive deficit between myeloablative allo-HSCT recipients and controls before HSCT (22.3% vs 17.2%; P=0.37) or at 1 year after (28.4% vs 19.5%; P=0.20).

However, the prevalence was significantly higher for myeloablative allo-HSCT recipients at 6 months (31.1% vs 16.5%; P=0.03), 2 years (34.6% vs 16.4%; P=0.02), and 3 years after HSCT (36.0% vs 8.7%; P=0.0015).

“From this data, it’s clear that we have to make strides in supporting allogeneic [HSCT] recipients in their recovery to ensure that we are educating patients and their families on signs of cognitive impairment,” Dr Sharafeldin said. “This data will help us identify patients at highest risk of cognitive impairment and inform the development of interventions that facilitate a patient’s recovery and return to normal life.”
