بسم الله الرحمن الرحيم
(Fatwa: 272/245/H=2/1439)
Your mother should read Ayatul Kursi three times after each salah with durood 3-3 times before and after and blow over her hands and pass her hands over her body wherever they reach. Also she should go to bed in the state of wudhu and read the dua of sleeping and lie on her right side.
Allah knows Best!
