"The important implications of this are that the optimal treatment may be different for each group, there may be different causes, and, for future clinical trials, it may be helpful to study specific groups separately."
The subtypes are:
- Inflammatory, in which markers such as C-reactive protein and serum albumin to globulin ratios are increased.
- Non-inflammatory, in which these markers are not increased but other metabolic abnormalities are present.
- Cortical, which affects relatively young individuals and appears more widely distributed across the brain than the other subtypes of Alzheimer's. It typically does not seem to cause memory loss at first, but people with this subtype of the disease tend to lose language skills. It is often misdiagnosed, typically affects people who do not have an Alzheimer's-related gene and is associated with a significant zinc deficiency.
