Answer:
You'll have to look to state law to determine if the POA document is sufficient. In most states, the Notary Public is supposed to ensure that the principal has the capacity to grant a POA. It may only be that the principal was physically unable to use a "normal" signature, yet all the mental faculties were there. You can always contact the Notary to inquire.
