Decisione estratta
No relevant change was shown; the remaining work capacity stayed at 50% and the invalidity degree remained 55%.
Motivazione estratta
The medical evidence, especially the RAD assessment, showed no worsening in the combined somatic and psychiatric situation during the comparison period. The psychiatric limitations did not increase the previously assessed impairment, and the income comparison was not shown to be unlawful.
