A new study suggests that asthma, a common chronic respiratory condition in children, may be linked to memory problems. Published in JAMA Network Open, this is the first research to show an association between childhood asthma and cognitive deficits, particularly in memory. According to the findings, the development of memory-related skills may be slower in children with asthma, which could potentially impact long-term cognitive health.

“This study underscores the importance of looking at asthma as a potential source of cognitive difficulty in children,” said Simona Getty, senior researcher and professor of psychology at the University of California-Davis Center for Mind and Brain. “We are becoming increasingly aware that chronic diseases, not just asthma but also diabetes and heart disease, can put children at risk for cognitive difficulties,” Ghatti said. The study reflects the need to better understand the factors that may either increase such risks or protect against them.

Researchers analyzed data from more than 2,000 children ages 9 and 10 with asthma across the United States, where about 4.6 million children live with this respiratory condition. During childhood, cognitive functions, including memory, typically undergo rapid development. However, Nicholas Christopher-Hayes, the study’s lead researcher and a doctoral candidate in psychology at UC Davis, found that children with asthma score lower on tests of episodic memory – a type of memory associated with specific experiences and emotions.

In a follow-up with a small group of about 500 children tracked for two years, researchers observed that those who had an earlier onset of asthma had slower progress in memory development. This finding raised concerns about possible long-term effects. “Asthma can set children down a path that increases their risk of developing more serious diseases later on.” dementia As adults,” Christopher-Hayes explained. Studies done on older adults have actually shown an association between asthma and an increased risk of dementia and Alzheimer’s disease.

Researchers suggest that the cognitive deficits seen in children with asthma may be due to chronic inflammation associated with asthma or persistent blockage of oxygen flow to the brain during an asthma attack. Supporting this, laboratory studies on rats have shown that common asthma medications can affect the hippocampus, a brain area that is important for memory and learning.

How to reduce the risk of asthma in children

Given the potential cognitive risks associated with asthma, you may be wondering how to protect your child’s health. The following preventive measures can help manage asthma and aid in overall cognitive development.

1. Reduce allergen exposure: Common triggers of asthma, such as dust mites, pet dander and mold, can often be reduced. Clean and ventilate living spaces regularly to reduce allergen build-up, and consider using hypoallergenic bedding.

2. Encourage a healthy diet: Antioxidant-rich foods, such as fruits and vegetables, can help support respiratory health and reduce inflammation. Omega-3 fatty acids, found in foods like fish and flaxseed, may also have anti-inflammatory properties that benefit the lungs.

3. Promote regular physical activity: Exercise is important for lung function, although it should be adapted to each child’s ability to avoid triggering asthma symptoms. Activities like swimming, which can enhance respiratory health without putting too much strain on the lungs, may be particularly beneficial.

4. Maintain a consistent sleep routine: Maintaining a consistent sleep routine is essential for both asthma management and memory function. Disrupted sleep can worsen asthma symptoms and impair cognitive abilities.
