Men's health information relating to attention deficit hyperactivity disorder (ADHD) may need to take into account the different effect of the condition on their movement.
Research from the American Academy of Neurology indicates that female ADHD sufferers and a control group exhibited similar levels of motion control during testing.
However, boys were up to twice as likely to have difficulty balancing, walking on their heels or tapping their toes.
Study author Dr E Mark Mahone suggests that the discrepancy may be due to the age at which the female brain reaches maturity - and that younger girls may experience similar difficulties to the boys tested.
As such, he argues that future studies may need to consider different age and gender groups in order to ensure that men's health information about ADHD reflects the specific response to the condition apparent in male patients.
Meanwhile, in other health-related news for ADHD patients, Massachusetts General Hospital recently found evidence that the condition has a number of effects on the likelihood that an individual will become nicotine dependent.
Sufferers are more likely to begin smoking than the population in general, the medical facility discovered, with the effect intensified among those whose friends and family smoke.
