No "other" question answer in disease type section for Alzheimers

[Rahul-Brito]

In both Alzheimers.tsv and the larger redcap csv or phenotype tsv, there should be a field called ""diagnosis_alz_dementia_mci_dt_other" according to this: https://github.com/sensein/b2aiprep/blob/4ca121b1e755c6cede7a9a7abf05f92534b423bf/src/b2aiprep/prepare/resources/column_mapping.json

which maps to the question from the clinical validation (https://github.com/eipm/bridge2ai-redcap/blob/main/data/en-us/instrument_pdfs/D%20Neuro%20Alzheimers%20Disease%20Mild%20Cognitive%20Impairment.pdf) that asks "If you selected "other", please specify:"

However, that field does not exist in any of our data exports. This field is important for clinical validation quantification; I was asked to quantify the number of AD patients we have, and the initial number I found was less than expected. According to a data collector, "Other" is often entered for subtypes that don't exist as a formal diagnosis e.g. "Alzheimer’s dementia"; these patients would still count as AD.

Is there a reason this field is missing? If not, we should add it back.

Thank you!
