I have been watching my husband slowly deteriorate over the weeks and months but suddenly last night it really hit home that this is dementia and is only going to get worse not better. He had taken himself off the the bedroom to put on his pjs. That in itself was surprising because normally he would only do that when we went together. Came back into the lounge wearing pajama shorts but still in the shirt he had been wearing all day. I suggested we go to bed and when we got there I handed him his pajama top to put on. He got really sharp with me insisting that he was wearing his pajama top and the item in my hand was the shirt he’d been wearing all day. I calmed things but was left feeling desperately sad. Of course he has no memory of it this morning.
