I look after a Parkinson's sufferer, they have had their disease for nearly 40 years now and subsequently have become very disabled, when combined with dementia/ alzheimers and so many years of prescribed drugs regularly becomes quite immobile, she slurs and mutters her speech, she can't move her head let alone her arms and her face often does seem to be lower on one side but that's just years of deterioration. other times shes bright as a button and is quite with it and im just concerned that if she were to have a stroke i wouldn't be able to distinguish it between one of her average bad days, are there any other things i could look out for except for the standard FAST symptoms.

Thanks in advance
