Reference excerpt

Judith Helen Cross (born 1961) is a British physician who is the Prince of Wales's Chair of Childhood Epilepsy and Honorary Consultant in Paediatric Neurology at Great Ormond Street Hospital for Children NHS Foundation Trust. She is also director of the UCL Great Ormond Street Institute of Child Health, London and a trustee of Young Epilepsy, in Lingfield. Cross has published on seizure, neuropsychological and behavioural outcomes in children who have undergone surgical resection for treatment of their epilepsy. Her research has focused on improving outcomes for children with early onset epilepsy. Cross' early research was into improving imaging techniques to determine areas of likely seizure onset in children with drug resistant focal epilepsy and has developed an epilepsy surgery programme based on her research. Cross conducted the first randomized controlled trial of the ketogenic diet in the treatment of children with drug resistant focal epilepsy and is endeavouring to conduct the same in the very young and adults. Recognising there was little in the way of control data with regard to neurodevelopmental progress, she initiated the North London Epilepsy in Infancy study, where a cohort of children was recruited at diagnosis in the first two years of life, and has been followed to at least three years. Cross planned to conduct a similar study over a wider geographical area, also examining phenotypes and genotypes. In 2015, Cross received an Order Of The British Empire for her services to childhood epilepsy. She was elected a Fellow of the Academy of Medical Sciences in 2026.

Early career Cross graduated with honours with a Bachelor of Medicine, Bachelor of Surgery from the University of Birmingham Medical School in 1984. She did her paediatric training in Birmingham and joined Great Ormond Street Hospital in 1990.

Worked examples

Example 1 — a first encounter with Helen Cross (physician)

Start with the simplest possible case. Write down what Helen Cross (physician) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Helen Cross (physician) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Helen Cross (physician) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Helen Cross (physician)

In research: Helen Cross (physician) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Helen Cross (physician) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Helen Cross (physician) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Alumni of the University of Birmingham, British neurologists, so understanding it makes those chapters shorter.
In everyday life: Look for Helen Cross (physician) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
