I am new to this forum, and am looking for advice for a problem which I understand is quite common in dementia sufferers. My husband was diagnosed with vascular dementia in January 2014. Since last winter his mental state has deteriorated quite rapidly. He doesn't recognise me as his wife, and he is constantly looking for ways to get 'home'. We live on a busy road, and as he has wandered several times I keep the front door locked. Of course, this increases his frustration and distress, but I am at a loss to know what else to do to keep him safe. In a way, he is aware of his situation, and distraction techniques don't work. His language is becoming very abusive - and I can see why. In his eyes I am keeping him imprisoned and he regards me as his jailer. Usually he isn't too bad in the morning, but becomes increasingly distressed as the day progresses. He has been prescribed half a tablet of Lorazepam 1 mg up to twice daily, and today for the first time I have had to to give him the second dose. Can anyone advise me how to deal with this?
