Can a sibling legally change an incapacitated parent's Will and POA?

Question Details:

My mother had a Will and POA created 5 years ago. Within the last 4 years she was diagnosed with dementia. A sibling within the last 3 months took it upon herself to change the Will and POA. No other siblings were told she was doing this. Is this legal? Especially since my mother was already diagnosed with a debilitating disease?
