Hilary Dawn Cass OBE FRCN FRCGP is a British honorary physician in paediatric disability at the Evelina Hospital, part of Guy's and St Thomas' NHS Foundation Trust, and former president of the Royal College of Paediatrics and Child Health. [1] She is known for establishing the UK's Rett Clinic for children with the neurodevelopmental disorder Rett syndrome, developing palliative care for children, and leading the Cass Review, completed in 2024.
Prior to Cass's appointment at the Evelina, she had been consultant at Great Ormond Street Hospital (GOSH) for 15 years. Her research and interests have included autistic spectrum disorders, cognitive impairment due to epilepsy, children with visual loss, and care of children with multiple disabilities.
In 2015 Cass received an OBE for services to child health. She was subsequently appointed chair of the British Academy of Childhood Disability.
Hilary Cass completed her early education at the City of London School for Girls. [2] [3] She studied at the Royal Free hospital medical school, graduating with a degree in medicine in 1982. [4]
Cass spent her early medical career in a general practice training scheme, during which she changed to paediatrics. [5] From 1992 to 2018, she was a consultant in neurodisability at three tertiary centres in the UK. [1] Her research and interests have included autistic spectrum disorders, cognitive impairment due to epilepsy, children with visual loss, and care of children with multiple disabilities, particularly where there are difficulties with feeding and communication. [4] In this field she has higlighted that medical innovations have resulted in a greater survival rate of children with severe incurable diseases, with the result that there are a greater number of children with severe disabilities. [6]
In 1992 Cass founded the Rett clinic, a national outpatient service for children with the neurodevelopmental disorder Rett syndrome, based at the Evelina Hospital, part of Guy's and St Thomas' NHS Foundation Trust. [7] [8] She later reported that self-injurious behaviour in Rett Syndrome had a prevalence of 73.8%. [9]
From 1994 to 2009 Cass was consultant in paediatric disability at Great Ormond Street Hospital (GOSH). [3] There, she was appointed director of Postgraduate Medical Education and held the post of deputy medical director. [4] During that 15-year period she also held some regional and national positions in medical education and policy development, including head of the London School of Paediatrics. [4] [10] At GOSH, she authored a book titled Snakes and Ladders , based on a programme she led that used role play to understand patient journeys in the NHS and to better skills of staff. [4] [11] [12] The book addresses communication between doctors and patients, and primary and secondary care. [12] Other topics covered include informed consent, medical negligence, medical paternalism, randomised controlled trials, and unlicensed treatments. [12]
In 2008 she published findings that did not support the opioid excess theory. [13] She reported on a large study she led that found no difference in urinary opioid peptide levels between those with autism and control subjects, and concluded that "opioid peptides can neither serve as a biomedical marker for autism nor be employed to predict or monitor response to a casein- and gluten-free diet". [13] [14]
Cass left GOSH after raising concerns about patient safety at the hospital. [15]
Cass joined the Evelina Hospital as consultant in 2009. [16] There, she developed palliative care services for children. [1]
In September 2020, Cass accepted an appointment to lead the independent Cass Review for the NHS into gender identity services for children and young people. [1] [17] The interim report of the Cass Review was published in March 2022. [18] It said that the rise in referrals had led to the staff being overwhelmed, and recommended the creation of a network of regional hubs to provide care and support to young people. The report noted that the clinical approach used by the Gender Identity Development Service (GIDS) "has not been subjected to some of the usual control measures" typically applied with new treatments, and raised concerns about the lack of data collection by GIDS. [19] [20] [21] The recommendations resulted in the closure of GIDS. [22] The final report was published on 10 April 2024. [23]
Cass said after the publication of the review that she had received ‘vile’ emails and that she was not travelling by public transport after receiving security advice. She also said that she would not participate in the forthcoming review of adult gender clinics. [24]
In May 2024 she made her first US media interview, on WBUR-FM's OnPoint, whom she told "'The evidence was disappointingly poor". [25] According to the New York Times, she said that US doctors were ‘out of date’ on gender care. [26]
In 2012 Cass was appointed president of the Royal College of Paediatrics and Child Health for a three-year tenure. [27] [28] Between 2017 and 2020 she was chair of the British Academy of Childhood Disability. [1] She is a trustee of Noah’s Ark Children’s Hospice, and was formerly chair of the charity Together for Short Lives. [1] [8]
Cass was appointed an Officer of the Order of the British Empire (OBE) in the 2015 New Year Honours for services to child health. [29] [30] In the same year the Royal College of Nursing awarded her an honorary fellowship (FRCN), and the following year she received one from the Royal College of General Practitioners (FRCGP). [1]
The diagnostic category pervasive developmental disorders (PDD), as opposed to specific developmental disorders (SDD), was a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication. It was defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM), and the International Classification of Diseases (ICD).
Great Ormond Street Hospital is a children's hospital located in the Bloomsbury area of the London Borough of Camden, and a part of Great Ormond Street Hospital for Children NHS Foundation Trust.
Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. FTT is usually defined in terms of weight, and can be evaluated either by a low weight for the child's age, or by a low rate of increase in the weight.
Neurodevelopmental disorders are a group of conditions that begin to emerge during childhood. According to the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5) published in 2013, these conditions generally appear in early childhood, usually before children start school, and can persist into adulthood. The key characteristic of all these disorders is that they negatively impact a person's functioning in one or more domains of life depending on the disorder and deficits it has caused. All of these disorders and their levels of impairment exist on a spectrum, and affected individuals can experience varying degrees of symptoms and deficits, despite having the same diagnosis.
The epidemiology of autism is the study of the incidence and distribution of autism spectrum disorders (ASD). A 2022 systematic review of global prevalence of autism spectrum disorders found a median prevalence of 1% in children in studies published from 2012 to 2021, with a trend of increasing prevalence over time. However, the study's 1% figure may reflect an underestimate of prevalence in low- and middle-income countries.
Intellectual disability (ID), also known as general learning disability and mental retardation, is a generalized neurodevelopmental disorder characterized by significant impairment in intellectual and adaptive functioning that is first apparent during childhood. Children with intellectual disabilities typically have an intelligence quotient (IQ) below 70 and deficits in at least two adaptive behaviors that affect everyday, general living. According to the DSM-5, intellectual functions include reasoning, problem solving, planning, abstract thinking, judgment, academic learning, and learning from experience. Deficits in these functions must be confirmed by clinical evaluation and individualized standard IQ testing. On the other hand, adaptive behaviors include the social, developmental, and practical skills people learn to perform tasks in their everyday lives. Deficits in adaptive functioning often compromises an individual's independence and ability to meet their social responsibility.
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism, Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life.
Autism, formally called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder marked by deficits in reciprocal social communication and the presence of restricted and repetitive patterns of behavior. Other common signs include difficulties with social interaction, verbal and nonverbal communication, along with perseverative interests, stereotypic body movements, rigid routines, and hyper- or hyporeactivity to sensory input. Autism is clinically regarded as a spectrum disorder, meaning that it can manifest very differently in each person. For example, some are nonspeaking, while others have proficient spoken language. Because of this, there is wide variation in the support needs of people across the autism spectrum.
Puberty blockers are medicines used to postpone puberty in children. The most commonly used puberty blockers are gonadotropin-releasing hormone (GnRH) agonists, which suppress the natural production of sex hormones, such as androgens and estrogens. Puberty blockers are used to delay the development of unwanted secondary sex characteristics in transgender children, so as to allow transgender youth more time to explore their gender identity. The same drugs are also used to treat other conditions, such as precocious puberty in young children and some hormone-sensitive cancers in adults.
Developmental regression is when a child who has reached a certain developmental stage begins to lose previously acquired milestones. It differs from global developmental delay in that a child experiencing developmental delay is either not reaching developmental milestones or not progressing to new developmental milestones, while a child experiencing developmental regression will lose milestones and skills after acquiring them. Developmental regression is associated with diagnoses of autism spectrum disorder, childhood disintegrative disorder, Rett syndrome, Landau-Kleffner syndrome, and neuro-degenerative diseases. The loss of motor, language, and social skills can be treated with occupational therapy, physical therapy, and speech therapy.

Mary Dorothy Sheridan, OBE, FFCM was an English paediatrician and public health officer who pioneered the study of child development.
Otto Herbert Wolff, was a German born medical scientist, paediatrician and was the Nuffield Professor of Child Health at Great Ormond Street Hospital. Wolff was notable for being one of the first paediatricians in Britain to set up a clinic for obese children. Later research into plasma lipids with Harold Salt pioneered the techniques of lipoprotein electrophoresis. He later conducted research into the role of lipid disturbance in childhood as a precursor of coronary artery disease and his recognition in 1960 of the rare condition of abetalipoproteinaemia. Wolff was also co-discoverer of the Edwards syndrome in abnormal chromosomes.

The diagnosis of autism is based on a person's reported and directly observed behavior. There are no known biomarkers for autism spectrum conditions that allow for a conclusive diagnosis.
The Independent Review of Gender Identity Services for Children and Young People was commissioned in 2020 by NHS England and NHS Improvement and led by Hilary Cass, a retired consultant paediatrician and the former president of the Royal College of Paediatrics and Child Health. It dealt with gender services for children and young people, including those with gender dysphoria and those identifying as transgender. The final report was published on 10 April 2024, and its recommendations were endorsed by NHS England and both the Conservative and Labour parties. The review has been criticised by some international medical organisations.
