Do CBD and THC gummies help Alzheimer's patients?

My mother is 77 years old and has had Alzheimer’s for about two years. She comes from a family with a strong history of genetic Alzheimer’s. Thankfully, her cognitive decline has been slower than expected, but we’re facing a different challenge.

She becomes extremely hyper and agitated, with some days being so restless that she doesn’t sleep at all. Her doctors have changed her medications several times and prescribed strong anti-anxiety medicines, but nothing seems to help.

My father and I are her primary caregivers. We’re managing, but it does take a toll on us. She also lost her son—my brother—six months ago, which may have added to her anxiety and restlessness.

I’ve read that CBD oil may help reduce agitation in some Alzheimer’s patients. Has anyone in India tried it for a loved one? If so, what was your experience? I’d also be grateful for any other suggestions that have genuinely helped with severe agitation or sleep.
