Louis Delasiauve

Louis Delasiauve is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Louis Delasiauve rather than just read about it. In short: Louis Jean François Delasiauve (14 October 1804, in Garennes-sur-Eure – 5 June 1893, in Paris) was a French psychiatrist. In 1830 he earned his doctorate in Paris, and for the next eight years practiced medicine in Ivry-la-Bataille.

Key takeaways

Louis Delasiauve belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Louis Delasiauve to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Louis Delasiauve from memory before moving on to harder problems.

Reference excerpt

Louis Jean François Delasiauve (14 October 1804, in Garennes-sur-Eure – 5 June 1893, in Paris) was a French psychiatrist. In 1830 he earned his doctorate in Paris, and for the next eight years practiced medicine in Ivry-la-Bataille. Afterwards he worked at the Bicêtre Hospital, and later became a director at the Salpêtrière, where he worked with epileptic and mentally handicapped patients. One of his better known assistants was Désiré-Magloire Bourneville (1840–1909). Delasiauve was a pioneer of child psychiatry, and an advocate of education for the mentally handicapped. He is best known for his research of epilepsy, being credited for describing three distinct types of the disease:

Idiopathic epilepsy: Absence of physical lesions; fundamentally a true neurotic disorder. Symptomatic epilepsy: Cerebral lesions being present; convulsions being a symptom and not the disease. Sympathetic epilepsy: Produced by the irradiation of abnormal impressions which can have their seat in all parts of the body except the central nervous system. His book Traité de l'épilepsie; histoire, traitement, médecine légale was translated into German by anatomist Friedrich Wilhelm Theile as Die Epilepsie (1855).

Worked examples

Example 1 — a first encounter with Louis Delasiauve

Start with the simplest possible case. Write down what Louis Delasiauve claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Louis Delasiauve 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 Louis Delasiauve 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 Louis Delasiauve

In research: Louis Delasiauve appears in science 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 Louis Delasiauve 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: Louis Delasiauve is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1804 births, 1893 deaths, French medical biography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Louis Delasiauve 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.
