A recent study published in JAMA Network Open suggests that early-onset asthma in children may lead to memory difficulties and cognitive development issues. Children with asthma performed worse in memory tasks and executive functions compared to those without asthma, with those who developed the disease early scoring lower on memory tests. Memory deficits in children with asthma may have longer-term consequences, including an increased risk of developing conditions like dementia. The study did not investigate the mechanism responsible for memory difficulties associated with asthma, but potential factors include prolonged inflammation and oxygen deprivation to the brain. Further research is needed to understand the impact of asthma on cognitive development in children.
