Three-part Clinical Question:
For patients with cognitive deficit following brain irradiation, dose the
application of HBOT result in any improvement in function?
Search Terms: Cognitive disorders, Brain irradiation, Late radiation
effects
The Study: Single-blinded randomised controlled trial without
intention-to-treat.
The Study Patients: Adult patients with cognitive impairment at least
1.5 years after radiation
Control group (n= 3) Nil specific treatment
Experimental group (n=4) 30 hyperbaric treatments at 3ATA for 115 minutes

Comments:
1.The one test outcome that significantly improved was a self-assesment test,
and could have been influenced by not being blinded
2. Multiple comparisons in small sample size means high probability that this
finding could be due to chance
3. Differences between control group and experimental group in tumour type,
localization and radiation field
