“Inquest Reveals Tragic Misdiagnosis in Girl’s Mental Health Death”

The mother of a 12-year-old girl who passed away weeks after being admitted to a specialized children’s mental health facility became emotional during an inquest where new information was presented.

Mia Lucas, residing in Arnold, Nottinghamshire, tragically ended her life at the Becton Centre for Children and Young People in Sheffield in January of the previous year. Following her sectioning under the Mental Health Act, Mia was discovered unresponsive and later declared deceased, sparking investigations into her case.

During the inquest, a pathologist disclosed that Mia was afflicted by a potentially treatable brain disorder. Her mother, Chloe Lucas, was visibly distraught as Professor Marta Cohen shared the results of blood tests, confirming Mia’s diagnosis of autoimmune encephalitis when she was found unresponsive on January 29, 2024.

The focus of the inquest revolved around determining whether Mia had autoimmune encephalitis, an inflammatory brain condition known to trigger severe psychiatric symptoms. Professor Cohen’s revelation of the conclusive new findings shed light on the cause of Mia’s tragic demise.

An expert neurologist, who initially deemed Mia’s condition as “possible” but not “probable”, was summoned back to the witness stand following the presentation of the new evidence. He affirmed that Mia did indeed have autoimmune encephalitis, attributing it as the root cause of her psychosis.

The sequence of events leading to Mia’s admission to the Becton Centre began when her family sought medical assistance at Queen’s Medical Centre in Nottingham on December 31, 2023. Mia’s escalating behavior, including attempting to access knives and experiencing hallucinations, culminated in her being sectioned under the Mental Health Act and subsequently transferred to the specialized facility.

The consultant neurologist expressed concerns over the diagnostic procedures conducted prior to Mia’s transfer, emphasizing the importance of comprehensive assessments in such cases. He acknowledged the challenges faced by the medical team but highlighted the potential risks associated with premature treatment for autoimmune encephalitis.

Reflecting on Mia’s deteriorating condition before her hospitalization, medical experts underscored the rarity and complexity of autoimmune encephalitis, especially in young individuals. Mia’s mother, Chloe Hayes, and other family members were present during the inquest, visibly moved by the unfolding revelations.

Describing Mia’s interests and aspirations, Ms. Hayes recalled her daughter’s passion for singing, arts, and horse riding, with dreams of pursuing a career in beauty or veterinary services.
