Visited mam at the home and arrived just in time to see her taking off her pyjama top and sitting on the sofa naked from the waist up and fighting off the care workers as they tried to persuade her to cover up. She was very angry and kept shouting at the carers and pushing them away. Eventually I persuaded her to put a slip on and she calmed down a little bit. It was a very distressing 15 minutes. She had been asleep all day on the sofa (hardly surprising as she had not slept in the previous 92 hours!) She has started taking mild anti-depressants and hopefully they will help calm her down and help her to sleep on a night time.
