Additional Information

Often the exact cause of a degenerative brain condition only becomes known after death. For this reason, when there is any doubt as to the underlying cause of a brain condition, it is considered safest not to accept a donation. It is thought that degenerative brain disease in the form of vCJD has been transmitted by blood transfusion.

Transient global amnesia is a temporary and isolated disorder of memory. Affected individuals are usually over 50 years of age and there is an association with migraine. There is no association with cerebrovascular disease.

Reason for Change
To clarify that CNS disease of unknown origin, and clinically isolated syndrome, are reasons for obligatory deferral and to permit individual risk assessment where appropriate.

Update Information

This is a requirement of the EU Tissue & Cells Directive.
