Does a wife have the right to dispose of the money and properties of her husband who is ill with Alzheimer's, and is it permissible for the children to eat and drink from this money as before?

If the father is ill and has authorized his wife to manage his wealth, the authorization remains valid unless he revokes it, and the wife is permitted to manage his wealth for the benefit of the family. However, if the illness causes him to lose his mind, then his insanity invalidates the authorization. In this case, the mother is not permitted to manage the father's wealth, and any management must be by order of the judge. If obtaining a judge's order is not possible, she may manage it with integrity and according to what is in the best interest, bearing in mind that a guardian is not permitted to manage the wealth of an interdicted person except in ways that benefit him.
