ADHD Symptoms Not Associated with Age, Study Finds

A study looking at the association between ADHD symptoms and age and biological measures of maturity has found no relationship between the two.

Researchers from several universities and hospitals in Sweden recently released results of a study that attempted to determine whether there was an association between age and other measures of biological maturity with ADHD.

ADHD symptoms were obtained from teacher and parent questionnaires for 251 elementary school students. Motor function, body weight and height, and skeletal age were calculated as non-behavioral measures of maturity.

The researchers found significant correlations between biological maturity and age, but not between maturity and ADHD symptoms. They also failed to find a correlation between ADHD and age. Although more research needs to be done, this study suggests that biological immaturity is not a factor in ADHD symptoms and diagnosis.
