The claimant witnessed an individual being struck and killed by a bus. He applied to the LAT for a catastrophic impairment designation, and disputing entitlement to ACBs and various medical benefits. The insurer argued that the claimant’s severe psychological impairments were the result of pre-existing schizophrenia that was already worsening prior to the accident. Adjudicator Neilson agreed with the insurer. Although she accepted that the claimant suffered a psychological injury from witnessing the incident, she found that the schizophrenia and severe psychological impairments demonstrated by the claimant were not a result of the accident, and that it would have developed regardless. The claimant showed a prodromal stage of schizophrenia from a young age, and he was at high risk from developing schizophrenia due to drug use and family history of psychosis. The evidence of the claimant’s mother was rejected as being non-credible as it was contradicted by the medical records of the claimant’s treating psychiatric team. Adjudicator Neilson also noted that she rejected the opinion of the claimant’s catastrophic impairment experts, as it was a chiropractor that provided the AMA ratings following assessment and diagnosis by a psychiatrist. Even using the opinion of the claimant’s psychiatrist, Adjudicator Neilson found that the claimant failed to prove that he suffered a Class 4 marked impairment or Class 5 extreme impairment in any of the four spheres of function as a result of the accident. Adjudicator Neilson did not need to address the claims for ACBs or medical benefits as the claimant had exhausted his medical benefits limits. However, in the event she was overturned with regard to the catastrophic impairment decision, she would have held that the unpaid ACBs related to transportation for the service provider, which was not payable under the SABS. She also found the claimed transportation to be inconsistent with the claimant’s ability to drive himself. Adjudicator Neilson also would have rejected the denied rehabilitation support worker services, as they were duplicative of services the claimant was already receiving at CAMH. Finally, Adjudicator Neilson would have rejected the claims related to the hotel stays, because they were claimed as medical benefits and incurred without a treatment plan. There were also procedural matters addressed at the outset of the hearing. Adjudicator Neilson allowed the insurer’s IE psychiatrist to observe the testimony of the claimant’s psychiatric expert; she allowed a defence medical report completed in the tort matter to be admitted as the insurer had access to the report and it had been provided to other expert witnesses; she allowed the insurer’s IE psychiatrist to testify to matters not contained in the report, while giving the claimant’s expert an opportunity to respond by way of reply evidence; and she restricted the claimant’s catastrophic impairment chiropractor to limiting his testimony to matters pertaining to the spine and musculoskeletal system only.
