Brain HealthCombined Exercise and Cognitive Training Boosts Brain Recovery in Older ICU Survivors
Surviving a serious ICU stay often leaves older adults with lasting cognitive decline, physical weakness, anxiety, and reduced quality of life — a syndrome sometimes called post-intensive care syndrome. This completed Indiana University trial enrolled 249 adults aged 50 and older who had been discharged from the ICU and randomized them to 12 weeks of combined physical exercise plus cognitive training, either intervention alone, or an attention control. The primary goal was to measure cognitive recovery using validated neuropsychological testing at 3 and 6 months. Secondary outcomes included physical performance, mood, anxiety, and quality of life. Researchers also explored whether the combined intervention reduced inflammatory markers and stress proteins while boosting neuroprotective growth factors like BDNF and VEGF — providing a potential biological explanation for any cognitive benefits observed.
