Cy Walsh was detained in December last year after being found not guilty of murder because he was mentally incompetent when he fatally stabbed his father at the family’s Adelaide home in July 2015.
In an application to the Supreme Court on Wednesday, Walsh asked to be allowed to attend hospital for treatment and rehabilitation after being diagnosed with MS.
He also asked for permission to be allowed to visit the local area around his detention facility.
The court heard the 29-year-old’s prognosis was uncertain.
The Director of Public Prosecutions asked for three expert reports to be prepared, given the seriousness of the case, and wants clarification on what type of MS Walsh has.
The application was adjourned until March.
Walsh was suffering a psychotic episode as a result of undiagnosed schizophrenia when he stabbed his father 20 times with a hunting knife, the court ruled in September last year.
Court documents revealed the extent of his mental health problem, which started in 2011 as he was backpacking around the world.
He heard voices he believed were from another dimension and, at times, he believed his father was the devil.
But he was not intoxicated by any drugs at the time of the stabbing, forensic reports showed.
In statements to the court, Phil’s wife Meredith said that she and her daughter were left heartbroken but she would continue to love and support her son.
She said there was a lack of information available to families like hers and called for increased mental health research and awareness.
