Twelve-year-old Mia Lucas tragically passed away in a psychiatric facility in England in January 2024, sparking an investigation that revealed a shocking twist. Initially believed to have succumbed to “acute psychosis,” new evidence presented at a hearing at Sheffield Coroner’s Court recently disclosed the real cause of her behaviours – a rare and potentially treatable brain disorder known as autoimmune encephalitis.

The revelation brought Mia’s mother, Chloe Hayes, to tears as she learned about her daughter’s underlying condition. Before her untimely death, Mia started exhibiting concerning symptoms such as hearing voices instructing her to harm herself and attempting to access knives from the kitchen, leading to her admission to the Becton Centre in Sheffield. Despite the efforts to monitor her closely, Mia was found unresponsive in her room on Jan. 29, 2024, eventually leading to her passing.


The initial narrative presented to the court suggested that there were no physical explanations for Mia’s psychosis. However, pathologist Marta Cohen’s updated findings from blood tests unequivocally pointed towards autoimmune encephalitis. This condition, as described by the Mayo Clinic, can have severe consequences, including psychiatric manifestations, shedding light on Mia’s distressing experiences.
The distressing journey began for Mia’s family on Dec. 31, 2023, when Mia’s behaviour escalated, prompting a visit to Queen’s Medical Centre in Nottingham due to concerns for her safety. Despite medical professionals initially attributing her symptoms to psychosis with no apparent physical cause, the subsequent turn of events tragically ended with Mia’s passing.
Dr. Mike Taylor, a pediatric neurologist consulted during the investigation, highlighted the challenges in diagnosing such a complex and rare presentation as AE, reflecting on the missed opportunities for further tests at Queen’s Medical Centre. The unprecedented nature of extreme psychosis in a child as young as Mia underscored the difficulties faced in recognising and addressing the underlying condition.
The impact of Mia’s case extends beyond her tragic passing, serving as a poignant reminder of the complexities surrounding mental health diagnoses in young individuals. As the Sheffield Coroner’s Court delves deeper into the circumstances surrounding Mia’s death, her family continues to honour her memory, recounting her passion for drawing, singing, and horseback riding, along with aspirations of owning a beauty salon or becoming a veterinarian.
The forthcoming conclusion of the hearing on Friday, Nov. 28, will hopefully provide further clarity and closure for Mia’s loved ones. Despite the heart-wrenching revelations surrounding her passing, the ongoing investigation serves as a critical step towards understanding and addressing the underlying factors that contributed to Mia’s tragic fate.
