Do not refer to ‘hidden disabilities’(medical model), the term ‘invisible impairment’ is preferred if you want to make the point that impairment is not always apparent.
Peidiwch â chyfeirio at “anableddau anweladwy” (model meddygol) – mae’r term “nam anweladwy” yn cael ei ffafrio er mwyn gwneud y pwynt nad yw’r nam bob amser yn weladwy.
