Mother get restless

My Mother these last couple of days in the evening hours gets very restless and wants to go some place and will not sit still she wants to get up and all of a sudden she has alot of engery and wants to just go. I have had a hard time with this because she won't sit still as she will do anyother time . I don't know what may cause this to happen , she will don't take her pills , but I give them to her in ice cream and that seems to work well. After she gets tried then she is clam and will sit still very well. The news programs she does not like so I don't watch them with her . I will watch I love lucy and full house these work well for her.Please give me some advice on this matter. Thank you for all your support. Rose Mary
