UNASSIGNED: Photodynamic therapy (PDT) is a commonly used and effective treatment option for @entity1489 . Apart from local side-effects such as @entity158 , @entity4 and erythema, no major adverse events occur in the majority of cases. Here we report on five @entity1 who developed @entity2414 such as @entity10931 immediately after PDT for @entity2517 . All PDT treatments were performed according to standard therapy protocols. The reported @entity1 had a memory gap for the entire procedure, as well as for the consecutive emergency medical care. Other common neurological causes such as @entity64 or @entity302 were excluded. No focal @entity51 were detectable. The symptoms had a fairly rapid onset following red-light illumination and were reversible without sequelae within 1-24 h. No correlation of the condition and @entity158 during the illumination could be revealed. Magnetic resonance imaging of the brain revealed @entity75 in the hippocampus as a potential morphological correlate in one @entity1 . The association between @entity2730 and PDT is novel and has not previously been reported. Even though PDT is considered a safe treatment modality, the possibility of neurological adverse events, albeit rare, should be kept in mind.
