What Researchers Did
Researchers reported on a case of a 27-year-old patient with late neuropsychiatric sequelae from carbon monoxide poisoning who received hyperbaric oxygen therapy 14 months post-injury.
What They Found
After 20 hyperbaric oxygen treatments, the patient's Parkinsonism and dystonia improved. Further improvements in mental speed, verbal fluency, and fine motor movements were observed after 40 sessions. Following 100 treatments, the patient regained independence, including the ability to drive and become gainfully employed.

Study Limitations
The primary limitation of this study is its design as a single case report, which provides a low level of evidence and cannot be generalized to a broader patient population.
