A fellow support group member is trying to appeal a decision in Canada for getting a disability pension for her husband who has PD. She needs referenceable material that relates to the length of time that symptoms can be present before a formal diagnosis is made. Her point is that her husband was affected by the PD well before a formal diagnosis and this had impacted his ability to pay into the Canadian pension fund. I have searched the Internet for some references but there is little documentation about the onset of Parkinsons before formal diagnosis. Can any of you help to identify references she can find and bring to her husband's pension hearing? Norm Ichiyen, Ruth Ichiyen (PD), 49/7
