I do ageism in reverse- I ask for the PT with the most years of experience (usually the department head). They will have had the most exposure to people with neurological issues.
This is painting with a huge broad brush, but in my experience and observation, the education, practice, and interest of many younger PTs is in Orthopedics. Neuropathy is a land far away and rarely heard from.
I had to wait four months for an opening with the department head in the large practice near me, but it was totally worth it. I go back to see him every year and a half for a few visits to update my home program and address any bad habits I’ve gotten into with walking.
