One thing worth noting is that some specialists believe that Alzheimer's has multiple subtypes, eg: https://www.foundmyfitness.com/episodes/dale-bredesen
"1. The inflammatory subtype of Alzheimer’s disease.
A type characterized by systemic inflammation, reflected in such laboratory results as a high hs-CRP (high-sensitivity C-reactive protein), low albumin:globulin ratio, and high cytokine levels such as interleukin-1 and interleukin-6.
2. The atrophic subtype of Alzheimer's disease — a reduction in support for synaptogenesis.
A type characterized by an atrophic profile, with reduced support from molecules such as estradiol, progesterone, brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), testosterone, insulin, and vitamin D, often accompanied by increased homocysteine and insulin resistance, the last feature of which Dr. Bredesen refers to as type 1.5 or glycotoxicity.
3. The cortical subtype of Alzheimer's disease — an environmental toxin-related type associated with chronic Inflammatory response syndrome (CIRS) that presents with more general cerebral atrophy and frontal-temporal-parietal abnormalities, resulting in an emphasis on executive deficits, rather than the more amnestic quality of hippocampal impairment."
