In plain language
Cardiologists and nurses working in cath labs scored lower on some memory and verbal fluency tests than unexposed controls. No dose-response was found, so radiation has not been shown to cause the difference.

What it found
Cath lab cardiologists and nurses scored significantly lower than unexposed controls on delayed recall, visual short-term memory and semantic lexical access.
Key figures: 83 exposed vs 83 controls
No dose-response relationship was detected.
The authors suggest the reduced skills point to alterations in left hemisphere structures, which are more exposed in interventional cardiology staff.
The authors recommend head protection as mandatory good practice for invasive cardiology personnel.
Limits to keep in mind
This is an observational comparison of exposed and unexposed groups, so confounding cannot be excluded, and no dose-response was found. The abstract gives no detail on country, how controls were matched or how exposure was measured.
