Cognition claims rest on Sagol trials that critics call small and contested — and HBOT for cognition failed a 2025 sham-controlled RCT, which is why ARK delists it for cognitive goals.
Extreme cost per session relative to every other HBOT provider in this directory.
Published on every entry, including the top-ranked ones. A clinic with no red flags listed has not been proved clean — it has not had one found in this research pass.

ARK never bills treatment and takes no share of what a clinic charges you — you pay the clinic or vendor directly. Prices shown are their own published prices, labelled with how they were verified.
What they do
12-week Aviv Medical Program: ~60 hard multiplace HBOT sessions (M–F, 2 hrs/day) plus cognitive training, neuropsychology, nutrition, physiotherapy and imaging.
The evidence behind the primary service
HBOT — FDA-cleared indications — grade D-, carried unchanged from the ARK Protocol Library. A clinic's score cannot exceed 20 of 100 on service evidence, so no clinic can rank well on an unproven therapy.
Delisted for cognition: HBOT failed its 2025 sham-controlled randomised trial, with more serious adverse events in the treated arm. ARK will not show it for cognitive goals.
The cleared indications are specific conditions — decompression sickness, non-healing wounds, certain infections. Wellness use sits outside them.
