IN another letter about supposed Wi-Fi allergy M L Edmunds (letters December 16) cites the ruling of a French court awarding a disability pension to a woman claiming her allergy to Wi-Fi and other signals made her unable to work.

Just to clarify, the court was merely required to rule on whether Marine Richard’s symptoms made her unable to work.

Her belief as to the origin of those symptoms was not relevant.

The award (which is being appealed) was in respect of the disabling symptoms and no judgement was made as to their cause.

The situation would be similar to an English benefits appeal relating to severe back pain where cause is often impossible to pin down but the symptoms can be convincingly demonstrated.

In the absence of any convincing evidence regarding the existence of EHS, other origins, including psychosomatic, remain more likely.

None of which is intended to imply that the symptoms are not real but randomly attributing a cause is not helpful.
