A new study has found that there are different effects of ADHD on brains of boys and girls.
The research shows the unique ways that ADHD affects boys and girls.
“The findings showed differences in the white matter microstructure between boys and girls,” said study co-author Lisa Jacobson. She is a pediatric neuropsychologist at the Kennedy Krieger Institute, in Baltimore.
“These structural differences were associated with observed behavioral differences,” Jacobson said. “Taken together, our findings provide preliminary evidence for unique differences in the brain’s white matter structure and function between boys and girls with ADHD.”
White matter enables regions of the brain to connect with each other.
According to Kathryn Moore, a psychologist at Providence Saint John’s Child and Family Development Center in Santa Monica, California, “Females are more likely to present with the inattentive symptoms of ADHD, while males are more likely to present with hyperactive and impulsive features of ADHD.”
Moore was not involved with the research. She noted that study authors could not explain reasons for their findings, and that the study does not explain why ADHD is diagnosed nearly twice as much in boys as it is in girls.
“The most striking finding in this study is that there are differences in brain functioning between boys and girls with ADHD,” she said. “Perhaps the disorder of ADHD is caused by these neurological differences, or perhaps ADHD causes these neurological differences.”
