On May 21, 2004, employee's work for employer exposed her to noxious fumes that caused her to experience a burning sensation in her nose and lungs, some minor burns on her face, an episode of temporary blindness, and sensations of extreme fear and panic. She settled her claim arising from this event with employer for permanent partial disability of 12.5 % of the body as a whole referable to psychiatric injury. She pursues this claim against the Second Injury Fund.
Employee suffers from nightmares related to the May 2004 work injury. Her recollection of the event is so upsetting that she avoids thinking or talking about it, even with her therapist. She believes her psychiatric problems are considerably worse following the work injury. Dr. Liss and Dr. Pribor disagree over the issue whether employee sustained any permanent psychiatric disability as a result of the work injury.
Dr. Liss has been board-certified in psychiatry since 1974 and is an expert in posttraumatic stress disorder (PTSD). Dr. Liss serves as a consultant to the Veterans Administration in the area of PTSD, and regularly treats a number of veterans with the disorder in his own practice. Dr. Liss opined that the work injury caused employee to suffer PTSD with panic disorder and a general anxiety disorder with depression. Dr. Liss
Improve her PTSD symptoms until at least 2008.

testified that employee suffered a panic attack in his office while recounting the events of May 21, 2004, for him, and that her recall of the event approached an almost hallucinatory level.
Dr. Pribor obtained her board-certification in psychiatry in 1991 and is a former student of Dr. Liss's. Dr. Pribor disagrees with Dr. Liss regarding the diagnosis of PTSD. Dr. Pribor believes the work injury did not cause employee to develop PTSD because employee's symptoms are more consistent with her preexisting psychiatric conditions. Dr. Pribor believes the work injury temporarily aggravated employee's preexisting panic disorder with agoraphobia, but otherwise did not cause her any psychiatric injury, and that employee ultimately suffered no permanent disability as a result of the work injury.
The administrative law judge reasoned that Dr. Liss lacks credibility because Dr. Liss acknowledged that employee missed some work and actively treated for psychiatric problems before the work injury, but nevertheless opined that employee's preexisting psychiatric problems were not a "hindrance." Award, page 4. We disagree with this analysis for two reasons. First, Dr. Liss is a medical expert, not a lawyer. That Dr. Liss may not understand the workers' compensation term of art "hindrance or obstacle to employment" does not, in our view, diminish his extensive qualifications in the area of researching, diagnosing, and treating PTSD. Second, the administrative law judge's credibility determination rests on the mistaken assumption that, for purposes of § 287.220.1 RSMo, the issue whether employee's preexisting conditions were hindrances or obstacles to her employment turns upon the extent of her past difficulties. This is not the proper focus of the inquiry, as we will discuss in more detail below.
We find Dr. Liss more credible than Dr. Pribor on the issue whether employee sustained PTSD and permanent disability as a result of the work injury. We find that employee's work was a substantial factor causing employee to suffer PTSD as diagnosed by Dr. Liss, along with an associated permanent partial disability to the extent of 15% of the body as a whole.
The parties have failed to suggest a date that employee reached maximum medical improvement from the effects of the work injury. As a result, we have been constrained to search the medical record for evidence relevant to this critical finding. Employee, in her brief, asks for permanent total disability benefits commencing on June 21, 2004, but fails to explain why we should find that she reached maximum medical improvement on that date. That date corresponds to employee's last treatment with Dr. Wudel, but the record reveals employee thereafter sought additional psychiatric treatment which helped to improve her PTSD symptoms until at least 2008.
We note that Dr. Chen, employee's treating psychiatrist from 2005 to 2008, recorded a gradual improvement in employee's PTSD symptoms with subsequent visits, until his note from April 24, 2008, in which he recorded employee's PTSD symptoms as follows: "residual PTSD sx nightmares." On May 22, 2008, in the last treatment note we have from Dr. Chen, the doctor recorded the same complaint: "residual PTSD sx nightmares." In light of this evidence, we find employee reached maximum medical improvement from the work injury on April 24, 2008, the last day that the treatment record reveals an improvement in her PTSD symptoms.
