"Abandoned from family"

Mum in ward 24 monklands hospital where was sectioned because of dementia. Ward having very limited visits and on many occasions can't book visits and can go many days where can't visit mum. When we see her she settles and get more relaxed and gets a lot from visits but is being denied this family time. Have read lots about NHS Lanarkshire having John's campaign about family contact for dementia patients so why not in place in the dementia ward. Mum can't leave cause of the order and we can't visit. Where is mum's human rights. How can NHS Lanarkshire breach people's human rights in this way. Understand they don't want everyone in at same time but only having visit times between 2 and 6 doesn't work with most working families. Surely it's better to spread visits throughout the day
