Hi, few weeks ago brother (early onset alzheimers) was more confused, rambling on, had few accidents (wee) said about getting taxi to airport, very poor movement and co ordination and swore at carer, never been aggressive before. GP checked him over all ok but couldn't provide urine sample, took me 6 days to get sample which was checked with dipstick all ok. He's been put on Risperidone for 1 month very low dose which makes him very tired. He's much better, I still think he had infection and think they should've issued antibiotics either way. How do we ever know if its just progression of the alzheimers or was infection 🤔
