Hi my parents live up north my sister and I both live on south coast with our families dad has recently been diagnosed with Alzheimer's (January 2013) although we believe it started lot earlier having looked after his mum with it we are aware of how difficult it is and how it will get worse, however lately dad has been very verbally abusive towards mum several times daily which is now becoming a problem as in upsetting her, my concern is her health is now starting to suffer under investigation for high bp, my sister and I phone daily and my brother who lives local sees them as often as possible, unfortunately they do not have internet access so she cannot access this type of support,they do get out almost daily for walks and lunches out but his mood swings often spoil these now.does anyone have any suggestions as to how we can help from so far away it's bad enough having dad the way he is now we don't want mum ill too. We do try and visit as often as we can work commitments make it difficult to do as often as we would like. Any advice would be welcomed.
