My Dad is 74 and was diagnosed with Alzheimer's August 2017. He lives with my mum. He has in the past taken to wander off and get lost. We recently acquired a tracking GPS device which helps us keep peace of mind. His condition has deteriorated so that he cannot really make himself understood or understand us, although there are decreasing moments of clarity. He has recently become increasingly aggressive with my mum, and after a recent missing period, I witnessed this. On advise from health advisors, I taken him to A & E. Here he became extremely aggressive and is now there is talk of a nursing home. Does anyone know how the long the aggression lasts over time? Mum is understandably at her wits end, but myself and my brothers are wondering if the period will pass
