Key legal question
When did the invalidating work incapacity begin for pension purposes?
Extracted holding
The beginning of the relevant work incapacity was not shown earlier than February 2007.
Extracted reasoning
The court relied on later medical assessments and clinic reports showing no concentration or memory deficits in 2004 and 2006, while the first clearly documented cognitive impairment appeared during the 2007 hospitalization. The 2008 MEDAS opinion was not convincing on the onset question because it lacked support in the file and conflicted with earlier findings.
