I posted a little while back. My husband's behaviour has changed in that he rarely leaves the house, is constantly either watching or on the internet regards horse racing, is verbally aggressive and has physically barged both my son and I. He is not interested in anything else and shows no empathy. He talks about the past a lot and of horse racing. I could go on but to cut a long story short he rang the DRS for the results of his CT Brain Scan today and they came back as satisfactory, no further action required. I had wrote to his GP and this is how he was initially referred for the CT Brain Scan. I am at a loss to what his behaviour (it is this that worry's me more than the memory loss) down to and I am really asking are the CT Scans reliable in showing Dementia? Of course he thinks there is now nothing wrong with him and his behaviour is not normal. Before all this he was a successful businessman and very active in politics.
