Scientists have discovered new evidence that inflammation during early childhood may affect how the brain develops.
The findings could help explain why some children later develop conditions such as autism or schizophrenia. The research was carried out by scientists at the University of Maryland School of Medicine and published in the journal Science Translational Medicine.
The human brain begins developing before birth and continues growing well into the teenage years. During this time, billions of brain cells must grow, connect, and communicate with each other in the right way. If this process is interrupted, it may affect learning, behavior, emotions, and social skills throughout life.
Conditions known as neurodevelopmental disorders occur when the brain does not develop typically. Autism spectrum disorder, attention-deficit/hyperactivity disorder (ADHD), and schizophrenia are examples of disorders linked to changes in brain development.
Although researchers know that both genes and the environment play important roles, many questions about their causes remain unanswered.
The researchers focused on a part of the brain called the cerebellum. This region is best known for helping control balance, movement, and coordination, but studies over the past several years have shown that it is also important for thinking, memory, emotions, language, and social behavior.
The team wanted to understand whether inflammation during early childhood could interfere with normal brain growth. Inflammation is the body’s natural response to infection or injury, and it is an important part of healing. However, when inflammation is severe or lasts too long, it can damage healthy tissues, including the brain.
To investigate this question, the scientists studied brain tissue donated from children who had died. Some of the children had illnesses that caused inflammation, such as infections or asthma, while others had died in accidents and showed no signs of widespread inflammation. The researchers used advanced technology that allowed them to examine individual brain cells in great detail.
The study found that two important types of brain cells, known as Golgi neurons and Purkinje neurons, did not mature normally in children who had experienced inflammation. These cells help the cerebellum process information and communicate with other parts of the brain. If they do not develop properly, important brain networks may not function as they should.
Purkinje neurons are especially important because they send signals from the cerebellum to many other brain regions involved in thinking, emotions, and behavior. Golgi neurons help organize signals within the cerebellum itself, allowing brain activity to remain balanced and well coordinated. Problems affecting either cell type could have lasting effects on brain function.
The findings suggest that inflammation during critical stages of childhood may interrupt the normal development of these brain cells. This does not mean that every child who has an infection or asthma will develop autism or schizophrenia.
Instead, the research points to inflammation as one possible factor that may increase risk in some children, together with many other genetic and environmental influences.
The discovery may eventually help researchers develop new ways to protect the developing brain. In the future, doctors may be able to reduce harmful inflammation during serious illnesses or create treatments that help vulnerable brain cells continue to develop normally. More research is needed before these ideas can become part of routine medical care.
This study represents an important step toward understanding how early-life experiences shape brain development. By learning more about how inflammation affects growing brain cells, scientists hope to find better ways to prevent or treat neurodevelopmental disorders in the future.
