Questione giuridica chiave
Whether the appellant proved a disabling health impairment entitling her to an invalidity pension.
Decisione estratta
No sufficiently established health impairment was proven with the required probability, so no pension entitlement arose.
Motivazione estratta
The file did not undermine the administrative expert opinion: no independent psychiatric disorder causing lasting substantial incapacity was established, and the alleged CFS/neurasthenia symptoms were not reliably attributable to a disabling condition.
