Best regards

I suggest you can apply to ADNI dataset to get access to that website

The Montreal Neurological Institute has an open science platform that has scans for AD/MCI, MS, ASD, and others.

There are numerous databases that you can use depending on what approach you would like to employ in your study.

I would recommend the following:

1. NG00024 - ADC3- Alzheimer Disease Center Dataset 3: NIA ADC cohort included subjects ascertained and evaluated by the clinical and neuropathology cores of the 39 past and present NIA-funded Alzheimer's Disease Centers (ADC).  Data collection is coordinated by the National Alzheimer’s Coordinating Center (NACC).

You can have access to a variety of datasets such as GWASs.

2. AD neuroimaging initiative (ADNI):

4. The Global Alzheimer’s Association Interactive Network (GAAIN):

Appreciating your wish for a compact dataset - if you do not include a detailed social and medical history you'll miss the opportunity to detect false positives. Spouses and others close to the client will have observations that can prove that positive signs have the long history required for a diagnosis of SDAT. Medical history will rule out the many other possible causes for early cognitive decline.

Good fortune on your work, Psychologist Paul McGaffey, PhD(ABD)
