Absent without leave - passive seizures

Dad has been very quiet for a few days. He thumbs a few pages of the newspaper but doesn't really read it, despite having read one every day of the 29 years that i have known him. He often stares at the television for long periods but we can't say how much he is actually interested and how much he is drawn to look in its direction simply because of the sound and motion. He is not interested in food, but mostly puts up with us spoon-feeding him and seems annoyed almost at our insitence that he tries to drink more too. He told me the other day "Stop trying to pump me full of water"
After Dad's recent seizures i realised that he has, i think, been having seizures for a while, but seizures of absence rather than active physical seizures. There are periods where he stares at nothing and it is impossible to get his attention through talking and waving at him. They tend to only last 10 - 20 seconds each time, but it has happened several times most days. He often says a few words of a sentence and then suddenly stops without finishing it. We had noticed that he 'zoned-out' every so often, but it was only after seeing him have an active seizure that i really thought about it. I'm sure he was only confused last night though, when he hiccupped loudly while the nurses were here and i said "Been on the sauce again Dad?" and he replied "No you've been on it for me!" Serves me right for being cheeky.

Lazy Bones

When i arrived last night Mum told me Dad had been in bed all day and the whole of the day before. I jokingly refer to him as 'lazy bones' when i see him in bed and on arriving last night, popped my head around the bedroom door to ask if he'd be joining us for dinner and eventually he did. With the return of his other symptoms (headaches and confusion) i think Dad's staying in bed is a result of his increasing passivity, rather than stubbornness. He seems to find it difficult to judge the passing of time. He can sit in one spot, with nothing to read, or without conversation, for a lot longer than he ever would have done before. Mum initially mistook Dad's reluctance to get up for stubbornness. She has the bedside manner of an angry elephant at the best of times, so there have been a few tense moments. We have learnt to give Dad oodles of extra time to get ready to go anywhere, especially appointments.
Dad had a measuring-session with the radiotherapy department today, in preparation for his next radiotherapy for the metastasis on his left side. He couldn't remember his birth date when asked (and laughed naughtily!) but was quick to recite the first line of his address. They have tattooed a tiny dot under his skin which they will align with other markers to ensure the radiotherapy is precisely targeting the metastasis. The radiotherapy will take place over 3 days next week.
Dad is mostly cheerful at the moment. He gets more pain in his head, but the oramorph seems to take care of that, for several hours at a time fortunately, so he is not taking much. He is sporting a bit of a silver-fox beard at the moment, which is strange to us as well as him as he has been clean-shaven his whole life. He is increasingly confused. Mum said she returned home from shopping yesterday to find him speaking on the phone. He said he was talking to the health insurance company and passed the phone to her. Mum found herself explaining the situation to a very confused insurance company employee as apparently Dad had called her, but behaved as if she had called him. He called his mother in the middle of the night a few months ago when he first had these symptoms too. In fact, Dad is sitting with me looking through the paper as i type this and he has just reached out, grabbed the phone and pressed a few buttons before putting it down again, so clearly it is something that attracts his interest. If you receive any strange late night calls from us we apologise in advance!
