We are interested in finding out if research has established any heredity connections between the presence of PD in the family and a higher incidence of Attention Deficit and/or Hyperactivity Disorder in future generations. Our son has recently been diagnosed as ADD and he has a paternal grandfather and maternal great-grandfather with PD. There are also other occurrences of ADD in cousins and uncles. Brian R.
