Doctors be trippin

Is it valid for a doctor to compare concussions to decades back? For example I went to a neurologist and he said concussions have become softer ya know, back in the day you had to black out for it to be considered a concussion. Like wtf okay well we’re not back in the day. I’m sure smart phones and other things don’t help.

Just frustrated trying to look for some diagnosis because I’ve been struggling for so long with head trauma symptoms. On anti depressants, done all the clinics, etc. Sometimes I get hopeless and feel invalidated. Please be respectful and know that my situation is real.
