Hello... I wonder if anybody can advise me?? My dad has an Alzheimer's diagnosis ...this is fairly recent...he is 77. He has gone downhill very rapidly in the last 18 months....seems like he's hardly with us....almost no short term memory. Anyway, he was rushed into hospital with sepsis recently and was put on oxygen and antibiotics and 24 hours later he was ringing all the family members ...he was back to his old self...it was unbelievable . However as soon as he went home he was back to being non-communicative and quiet again. I've asked his GP to look into this.... whether the increased oxygen or the antibiotics or the medical monitoring of his medications whilst in hospital could be the factor ? He appeared normal for 24 hours. The GP monitored his oxygen levels in his blood for a few weeks, and they were a little bit borderline... but no one is interested in investigating this further? My mum is so worn down that she doesn't want to pursue this .....she doesn't feel able to cope with getting him to appointments or anything. Maybe it's wrong for me to interfere... I feel at a loss....I don't live in the same part of the country, so it's really complicated for me to chase up anybody or be on hand to take my dad to appointments. Any advice would be appreciated
