Kernrechtsfrage
Whether the MEDAS medical assessment was unreliable and required further neuropsychological/radiological/rheumatological investigations.
Extrahierter Entscheid
The MEDAS report retained evidentiary value; the lack of additional examinations did not render it unusable.
Extrahierte Begründung
Whether further tests were needed was left to the expert physicians' discretion; the claimant's objections attacked only the evidence evaluation and did not show an obviously incorrect factual finding.
