Enuresis and ADHD may seem to run together in children but there is no actual proof to support it. According to the following study: Clinical correlates of enuresis in ADHD and non-ADHD children by Biederman J, Santangelo SL, Faraone SV, Kiely K, Guite J, Mick E, Reed ED, Kraus I, Jellinek M, Perrin J. carried by the Pediatric Psychopharmacology Unit (ACC 725), Massachusetts General Hospital, Boston 02114, USA, the following conclusions were drawn:
1. Bed-wetting did not increase the risk of psychopathology in children. The risk for developing bed-wetting was equal in ADHD children and normal children
2. Bed-wetting did not cause any psychosocial hardship or developmental problems
3. Bed-wetting was associated with an increased risk of developing learning disabilities, weakened intellectual functioning, as well as a lesser school achievement record in normal children but not in children with ADHD; and
4. The identical model of results was derived after comparing bed-wetting children of primary versus secondary and of nocturnal versus diurnal variants. The results suggested that the clinical results of bed-wetting differed in ADHD and non-ADHD children
