Thanks Sandy for the useful snippet of information:
(Many of our most
immune damaged children seem to be electrosensitive).
This ties in with a lot of the evidence accumulating in this and other
groups that immune system problems and related illnesses are often a trigger
to electrosensitivity (in adults as well). Conversely, treating the
underlying illnesses (when identified, which is often difficult) seems to
have helped reduce ES for many people in the group.
This might link to possible treatments to alleviate autism.

Dear Bill and Emil,
Thanks for very useful replies. Would you mind if I copied your
replies amongst our "treating autism" friends/. (Many of our most
immune damaged children seem to be electrosensitive).
With thanks,
Sandy
