Losing my mind, Canadian neurologists are completely incompetent

I am reaching my breaking point. Despite having a grossly abnormal PET MRI showing atrophy and hypometabolism (consistent with encephalopathy), nobody in this supposedly first world country I live in can be bothered to do a diagnostic CSF lumbar puncture. This is a basic 5 min procedure that can diagnose conclusively.

I am 7 months into this odyssey. Losing my mind and all hope. I am going to self refer to Mayo Clinic as a last ditch attempt before I give up.
