The claimant appealed the Tribunal’s decision that she did not suffer a catastrophic impairment. The Tribunal found a 51 percent WPI. The claimant argued that the Tribunal’s refusal to rate her sleep impairment was unreasonable. The Court dismissed the appeal, concluding that the Tribunal did not err by not rating the sleep impairment. The Tribunal did not conclude that sleep disorder was not a rateable condition, but that the claimant and her experts did not give persuasive evidence that the claimant herself suffered a sleep impairment that warranted rating under the AMA Guides.
