Last week I posed the question to the AFTD helpline to see if there was any research investigating a possible relationship between FTD and Autism. The AFTD helpline is a free service for FTD Patients, Caregivers and the public to get accurate answers to FTD questions. The following answer was given to me by Sharon Denny, the AFTD Program Director:
These examples are two ways that researchers are trying to learn why and how social thinking and behavior symptoms occur in different disorders. It's interesting stuff, but does not indicate that the various disorders are linked through a common cause, gene, or pathology.
Somehow I just lost the rest of what I wrote here. (NAFW) is in effect and I didn't curse out loud. Oh well, there will always be a tomorrow.
