The protocol is only helpful with a select group of people. I believe many diagnosed with Alzheimer's actually have other forms of dementia. My father was told he had Alzheimer's but his dementia started 30 years prior to his death. I believe he had ischemic dementia from decades of Central Sleep Apnea.

I know others with AD diagnoses who have a history of concussions. They say that people with a history of multiple concussion have an 18 fold increased risk of AD. I think they have an increased likelihood of a misdiagnosis of AD.

So, the few who improved likely did not have AD but rather a different malady.
