JOINT REPORT OF DR MERIMA ISAKOVIC (CLINICAL NEUROPSYCHOLOGIST) AND DIANA LE CLERCQ (PSYCHOLOGIST) DATED 25 SEPTEMBER 2022
"Mr O'Neill's estimated overall intellectual abilities fell in the extremely low range which were significantly and clinically unusually lower that expected (difference found in less than 1% of the population). Mr O'Neill's ability to comprehend language and express himself verbally fell in the very low range which was significantly and unusually lower than expected (difference found in less than 1% of the population). His ability to organise and manipulate visual information fell in the very low range and was significantly and unusually lower than expected (difference found in 1.2% of the population). His verbally based attentional abilities fell within the extremely low range and were significantly and unusually lower than expected (difference found in less than 1% of the population). His ability to work quickly and efficiently with visual information fell within the extremely low range and was significantly and unusually lower than expected (difference found in less than 1% of the population)."
"Mr O'Neill meets the DSM-5 diagnostic criteria for 332.0 (G20) Parkinson's disease 294.11 (F02.81) major neurocognitive disorder most likely due to Parkinson's disease without behavioural disturbance that appeared chronic, progressive, and with the onset likely to precede the time of the initial diagnosis."
"Major neurocognitive disorder: according to the diagnostic and statistical manual of mental disorders (DSM-5) Mr O'Neill's cognitive functioning had declined from premorbid functioning in several cognitive domains (complex attention, executive function, learning and memory, language, and perceptual motor) which is demonstrated above."
"Due to the impact of neurocognitive disorder further escalated by severity of major depression, PTSD, general anxiety, and devastation in adjusting to what he described as lost honour and integrity due to the accusations brought by Mr MC and the subsequent court conviction, Mr O'Neill has suffered widespread deterioration in his cognitive functioning. He has been having significant difficulties with complex attention, executive function, learning and memory, perceptual motor, and language skills and abilities that would best be explained as being a result of his acquired disability. This was evidenced by standardised assessments, clinical observations and collateral information.
All of Mr O'Neill's cognitive abilities are identified to be significantly and abnormally lower than his premorbid level of functioning, which means that he will experience significant difficulties keeping pace with other men his age on most tasks or participating in critical situations when he might be expected to articulate well or advocate for himself.
Mr O'Neill had significant difficulty demonstrating his verbal abstract reasoning skills. He had difficulties perceiving, integrating and organising visual information. Mr O'Neill took longer to complete tasks, required additional time to learn new material, and was unable to quickly complete two tasks simultaneously. Mr O'Neill presented with difficulty keeping verbal information in mind while performing a task and was unable to maintain his attention whilst filtering out irrelevant information. His ability to sequence digits was an area of weakness on his overall cognitive profile.
While Mr O'Neill was able to retrieve verbal and visual information immediately after a presentation, he had significant difficulty recalling this information after 20 to 30 minute delay. Further, Mr O'Neill was unable to use 'cues' to spark his verbal or visual memory."
- Under the heading of "Recommendations" the report informs me:
"…Given his extremely vulnerable health status, severe loss of weight, inability to manage CPAP machine, inability to walk or stand up independently as well as marked deterioration in cognitive abilities and severe intensity of his depressive state with active suicidal desires and attempts, the life expectancy for Mr O'Neill would likely be below the age of 90 years.
Mr O'Neill presented with extreme hopelessness and risk of self‑harm by suicide. His marked cognitive decline presented at the level of disability and has been affected by health deterioration initiated by the neurocognitive disorder, but further escalated by severity of major depression, PTSD, general anxiety and devastation in adjusting to what he described as lost honour and integrity due to the accusations brought by Mr MC and the subsequent court conviction.
The finding of this through clinical and neuropsychological assessment strongly supported the clinical opinions of Dr David Williams, neurologist, as well as Dr Michael F Dwyer, consultant psychiatrist, that Mr O'Neill has not been capable of adequately representing himself, advocate or defend himself in the court proceedings of any kind where he would be required to comprehend the verbal information, process it reasonably, and provide directions to his legal representatives. In addition, his severe depression and suicidality would likely escalate to the level of undoubtable suicidal execution. The participation to the expected court proceedings in New South Wales would therefore represent the life-threatening risk for Mr O'Neill."
