Questione giuridica chiave
Whether the claimant is entitled to a helplessness allowance under invalidity insurance.
Decisione estratta
No entitlement was shown because the claimant's condition had not materially worsened since the last final denial and the required level of helplessness was not established.
Motivazione estratta
The Federal Court upheld the cantonal findings based on medical reports and the home assessment; the arguments about continuous help from the spouse did not prove legally relevant helplessness.
