In Jan my father developed vascular dementia - and was a handful for us to take care of - a visiting geriatric doctor put us in touch with a doctor in Wpg that was knowledgeable in cannabis treatment for elderly dementia patents and prescribed for my father the proper combination to use and dosage - 2 weeks after starting this (before and during this time he was agitated and hard to control 24/7) he started sleeping more than 3 hours a night and by the third week he slept all the way through - and with exception of maybe 4 times since then he has not reverted back to his dementia and has stayed in our reality most of the time - doctor treating his said if he didn't see the change himself he wouldn't have believed it
