Well, applying and waiting to get rejected makes about as much sense as going before a Board of inquiry with no Prep. Yeesh.
There is a long list of stuff you need:
If you have never been placed on an anti seizure med and never had one:
2 years down
Mri optimized for hemosiderosis
Usually a carotid doppler study and Echocardiogram.
Summary letter from your doc discussing your ASCVD risk factors and their mgmt.
Stress treadmill run.
Current neurologist's detailed evaluation
Depending on location, current Humphrey 24-2 or 30-2 visual fields and 8500-7.
FAA neuro- cognitive evaluation IAW current spec sheet.
Whatever operational assessment of any weaknesses per the AME or an occupational med doc.
The shops doing the neuroCog are just used to having the letter. But actually if you do it right, and someone in the know provides the referral and specs (Usually a knowedgable AME), and have everything done and favorable, you can get the agency issuance in about 2 months
