ADHD Drugs Can Affect Later Generations

“Because of this male-specific effect, we investigated the effects of MPH through the paternal line and observed the same behaviors in several generations of their descendants not directly administered the drug.”

By studying guppies, scientists at the University of Toronto and Florida State University found that behaviors affected by methylphenidate hydrochloride (MPH) – the active ingredient in stimulants such as Ritalin and Concerta used to treat ADHD—can be passed along to several generations of descendants.

“We exposed male and female Trinidadian guppies to a low, steady dose of MPH and saw that it affected the anxiety and stress-related behavior of males, but not females,” said Alex De Serrano, a Ph.D. candidate in the department of ecology and evolutionary biology (EEB) in the Faculty of Arts & Science and lead author of a study published recently in Scientific Reports.
