You have my heartfelt sympathy. It is so heavy a cross to bear, may the Lord console your father and you and your family.
Alzheimer's runs in my family, my grandmother and great grandmother both had it. Even now I am praying for my for my mother, hoping it will pass her by as I notice signs of forgetfullness and hope it is not the beginnings of what it may be. May the Lord have mercy on her please.
He chooses our crosses for us. There is no better one to choose our crosses than Our Lord however hard they are to bear. May God have mercy on your father and help him through this time.
I will look a little to recommend a book to you shortly, God willing, please look in your message box here.
Perhaps take up the practice of repeating with love the Holy Name of Jesus, and short prayers and aspirations with the Holy Names of Jesus, Mary and Joseph.
INFANT JESUS PRAYERInfant Jesus meek and mild
look on me a little child.
Pity mine and pity me,
suffer me to come to Thee.
Heart of Jesus I adore Thee,
heart of Mary I implore thee,
heart of Joseph pure and just,
in these three hearts I place my trust.
