I just had to comment on this....

Yes, I would agree that sometimes we don't make those connections with other people, but this study seems to be only about PD impairment, and interactions with people are more than one-way......

There is another much more widely acknowledged aspect to communication, and that is that people who do not have PD do not 'read' us well, because of the way we look, or because they are unaware that our lack of facial expression is not a mood but a symptom, or their own reactions to disability, and to social fears. I would say this is much more disabling. I have poor facial recognition for people who have aged or changed their look, hair, etc. I can recognize this in myself, as I can any speech communication issues. And apologize if I have goofed up.

People with disabling conditions do more often than not feel socially awkward to some degree, and it is not all about their condition.

Disability is a two way street.......
