More than half of the society's members had joined the Army. She spoke of them \"heroically ministering to the wounded amongst our valiant soldiers and freely dispensing their science, their talent, their courage, their fraternal devotion, their joyous bravery.\" Nobody knew then how long the war would last—or how profoundly it would change neurology forever.\u003c\/p\u003e\n\n\u003cp\u003eJust a few months later, the eminent neurologist Pierre Marie (1853–1940) foresaw the transformation clearly: \"The war will have been an inexhaustible source of new knowledge for us in the most varied of fields. In particular, neurologists must recognise that they have learned a great deal, in a domain where they had much to discover, that of war neurology.\"\u003c\/p\u003e\n\n\u003cp\u003eThe conflict created conditions never seen before in medical history. For the first time, large numbers of neurologists were concentrated in specialised wartime neurology centres, confronted with more neurological patients than any generation of doctors had ever encountered. This concentration produced a flood of scientific papers covering every field of neurological science, published in journals like \u003cem\u003eLa Revue Neurologique\u003c\/em\u003e during the war and the post-war years.\u003c\/p\u003e\n\n\u003cp\u003eTwo factors made the neurological toll especially severe:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShrapnel injuries\u003c\/strong\u003e affecting the spine and skull were common, especially in the early years of the war\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeuropsychiatric disturbances\u003c\/strong\u003e occurred in high numbers but were greatly under-estimated at first—a phenomenon that came as a \"totally unexpected surprise\" to military medical services\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe French health service was initially disorganised and had not anticipated the nature of these injuries. The metal \"Adrian\" helmet, which reduced the severity of head injuries, was not introduced until the spring of 1915, and even then only gradually. Managing soldiers with psychological and neurological symptoms remained problematic throughout the entire conflict.\u003c\/p\u003e\n\n\u003cp\u003eSpecialised neurology centres were officially created in October 1914 at the headquarters of military regions, at regional hospitals, and in university cities where the most well-known neurologists were mobilised. By the spring of 1915, additional neurology centres were established near the front lines to treat patients more efficiently and avoid needless transfers to rear facilities.\u003c\/p\u003e\n\n\u003ch2 id=\"civil-hospitals\"\u003eNeurologists in Militarised Civil Hospitals\u003c\/h2\u003e\n\n\u003cp\u003eThe university neurologists in France's major cities were generally too old to be officially mobilised, yet most continued to serve in the militarised neurology departments of large hospitals. In Paris, Jules Dejerine (1849–1917), Pierre Marie, Achille Souques (1860–1944), and Henry Meige (1866–1940) all treated injured soldiers.\u003c\/p\u003e\n\n\u003cp\u003eIn October 1914, the famous \u003cstrong\u003eLa Salpêtrière hospital\u003c\/strong\u003e was transformed into a military neurology centre. Jules Dejerine and his wife Augusta Dejerine-Klumpke worked there tirelessly. By the end of 1915, the centre had close to \u003cstrong\u003e300 beds\u003c\/strong\u003e. Despite his fragile health, Dejerine refused to rest. As one colleague recalled: \"He refused to rest, a necessity at his age, and because he overworked himself, at a time when the symptoms of the disease that would take his life were making themselves felt, he, too, could be considered a victim of national duty, a war victim.\" He suffered his first attack of uraemia (kidney failure) on 26th January 1916, returning from a meeting of military neurologists in Doullens. Dejerine, suffering from terminal kidney failure, died of acute pulmonary oedema on 26th February 1917.\u003c\/p\u003e\n\n\u003cp\u003ePierre Marie took over as head of the militarised department at La Salpêtrière. Working with his chef de clinique Charles Chatelin (1884–1948) and the surgeon Thierry de Martel (1875–1940), he focused on skull injuries. The numbers were staggering: \u003cstrong\u003e\"In my department at La Salpêtrière, we examined nearly 5,000 cases of skull injury in 1915 and 1916,\"\u003c\/strong\u003e Marie reported. He recognised that these war injuries opened a unique window into brain function: \"War injuries have shown us a different set of facts: lesions of the cortex, with more or less complete exclusion of white matter. Consequently, this new pathology is infinitely closer to the data of experimental physiology than was the old cerebral pathology.\"\u003c\/p\u003e\n\n\u003cp\u003eAcross Paris, the militarised neurology department of \u003cstrong\u003eLa Pitié hospital\u003c\/strong\u003e was directed by Joseph Babiński (1857–1932), a name still familiar to medical students today for the \"Babinski sign.\" He also served in the military hospital set up in the Lycée Buffon, where he worked alongside neurologist Jules Froment (1878–1946). Their collaboration produced several publications, particularly on nervous disturbances involving autonomic disorders (problems with the body's automatic functions like heart rate and digestion). Many of Babiński's internes and colleagues left for the front lines; some never returned.\u003c\/p\u003e\n\n\u003cp\u003eDespite the death and disruption, the Société de Neurologie—which had been dormant—progressively resumed its activities at the beginning of 1915. Babiński and his Parisian university colleagues played a major role in these meetings, which focused essentially on war neurology and were presided over by Augusta Dejerine-Klumpke.\u003c\/p\u003e\n\n\u003ch2 id=\"guillain-barre\"\u003eGuillain and Barré: A Wartime Partnership That Changed Medicine\u003c\/h2\u003e\n\n\u003cp\u003eFew medical discoveries have a more direct link to World War I than \u003cstrong\u003eGuillain-Barré syndrome\u003c\/strong\u003e, a condition in which the body's immune system attacks the peripheral nerves, causing weakness and sometimes paralysis. The story begins with two French neurologists brought together by the war.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGeorges Guillain\u003c\/strong\u003e (1876–1961) had trained under Fulgence Raymond (1844–1910) and Pierre Marie. Unusually for the time, he supplemented his Parisian education by visiting neurology departments at major American universities. He became a hospital physician in 1906 and passed the difficult agrégation examination (the gateway to professorship) in 1910.\u003c\/p\u003e\n\n\u003cp\u003eWhen war was declared, Guillain was 38 years old. Although he had been exempted from military service in 1899 for \"weakness,\" he voluntarily enlisted on 21st September 1914 as a médecin aide-major de 2e classe (a junior medical officer). His wartime career was remarkably active:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJanuary 1915:\u003c\/strong\u003e Assigned to the Val-de-Grâce hospital in Paris\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMarch 1916:\u003c\/strong\u003e Transferred to the hospital in Amiens and other hospitals in northern France during the Battle of the Somme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJune 1917:\u003c\/strong\u003e Became director of the medical and scientific department of the Bouleuse evacuation hospital in Marne (north-western France)—a mobile hospital that also served as a school for war medicine and surgery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd of the war:\u003c\/strong\u003e In charge of the Longvic medical centre for aviation units\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eJean-Alexandre Barré\u003c\/strong\u003e (1880–1967) had a parallel path. After serving as an interne in Nantes and completing military service in 1901, he was accepted as an interne in Parisian hospitals in 1906. Working alongside Joseph Babiński, he discovered neurology and abandoned his initial plan to become a surgeon. He finished his training with Pierre Marie and Achille Souques and defended an innovative thesis in 1912. When war broke out, Barré was Babiński's assistant. As a reserve military physician since 1902, he first served in ambulance unit 12\/11, then in various military hospitals in the Nord region. In October 1917, he was transferred to the neurology centre in Nantes, and in September 1918, having attained the rank of médecin major, he became director of the Centre de neuro-psychiatrie of the Eastern Region.\u003c\/p\u003e\n\n\u003cp\u003eThe war brought Guillain and Barré together in the same medical units. Their collaboration was remarkably productive. Their collected papers, published in 1920 as \u003cem\u003eTravaux Neurologiques de Guerre\u003c\/em\u003e, reflected a unique opportunity: \"We were able to study the injuries of the nervous system at a very early stage and collate an exceptional body of documents on certain physiological and clinical questions.\"\u003c\/p\u003e\n\n\u003cp\u003eThe landmark moment came in \u003cstrong\u003eOctober 1916\u003c\/strong\u003e, when they drew on the physics knowledge of André Strohl (1887–1977)—a doctor of both physics and medicine—to describe what they called the \"syndrome of radicular neuritis with hyperalbuminosis of the cerebrospinal fluid without cellular reaction.\" Today, we know this condition as \u003cstrong\u003eGuillain-Barré syndrome\u003c\/strong\u003e. After the war, Guillain and Barré returned to this publication, which would bring them much of their lasting fame.\u003c\/p\u003e\n\n\u003cp\u003eBeyond this famous discovery, the pair also improved techniques of neurological examination and developed new tests of spinal reflectivity that helped doctors determine exactly where along the spine lesions had occurred. They were particularly interested in spinal cord injuries, which carried considerable mortality. Their experience led them to emphasise early management, including systematic surgical exploration, treating associated vertebral fractures, and improving diagnosis of spinal lesions. However, the two physicians admitted they could do little against secondary bacterial meningitis, a frequent cause of death in these patients.\u003c\/p\u003e\n\n\u003cp\u003eGuillain and Barré also pushed back against the common practice of labelling mysterious nervous problems as \"hysteria.\" They contested the hysterical aetiology attributed to nervous problems that developed following exposure to exploding munitions. Guillain was careful not to deny that genuine hysteria existed, but he argued it was relatively uncommon: \"Like all neurologists, I have observed what are known as hysterical or functional disturbances that can be cured rapidly through suggestion and persuasion; I have also seen exaggerated or simulated disturbances, but one mustn't confuse the matter with overly simplistic diagnostics. These disturbances are far from frequent.\"\u003c\/p\u003e\n\n\u003cp\u003eGuillain's philosophy of war neurology was summed up in his own words: \"In our neurological work, we attempted to wed the lessons of physiology with those of clinical medicine and to perfect our investigative methods by the study of new signs and thereby construct a rational foundation for establishing a prognosis; we also tried to determine in patients with nervous system injuries, the indications for and against surgery.\"\u003c\/p\u003e\n\n\u003ch2 id=\"cruchet\"\u003eRené Cruchet and the Controversy Over Encephalitis Lethargica\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eRené Cruchet\u003c\/strong\u003e (1875–1959) was an interne in the Bordeaux hospitals who became an assistant professor in 1907. A paediatrician by training, he had long been fascinated by abnormal movements. In his doctoral thesis, he was the first to propose a possible organic (physical) origin for \u003cstrong\u003eGilles de la Tourette syndrome\u003c\/strong\u003e—the condition characterised by involuntary tics and vocalisations. His 1907 book on dystonia (a movement disorder causing involuntary muscle contractions) was the first of its kind.\u003c\/p\u003e\n\n\u003cp\u003eDuring World War I, Cruchet served as a regiment physician in the emergency units at the front. On \u003cstrong\u003e23rd February 1916\u003c\/strong\u003e, during the Battle of Verdun, he was injured when a shell exploded nearby, rupturing his eardrums. His citation for bravery read: \"Working under fire, organised the reception and evacuation of the numerous injured soldiers that filled his emergency unit. Calm, courageous and competent leader.\" After his injury, he was assigned to various neurology centres and then put in charge of reorganising the Bar-le-Duc military hospital. While stationed in Meuse (north-eastern France), he met the médecin auxiliaire \u003cstrong\u003eAndré Breton\u003c\/strong\u003e (1896–1966)—who would later become famous as a writer and theoretician of Surrealism.\u003c\/p\u003e\n\n\u003cp\u003eCruchet's most significant wartime contribution was the identification of a new neurological disease. With the help of François Moutier (1881–1961) and Albert Calmette (1863–1933), he brought to light a condition with all the appearances of an epidemic. On \u003cstrong\u003e1st April 1917\u003c\/strong\u003e, he submitted a paper on forty cases of subacute encephalomyelitis to the Société Médicale des Hôpitaux de Paris; it was published on 27th April 1917. He wrote: \"In the successive centres where I directed neuropsychiatric departments as a specialised médecin major, I remarked the undeniable frequency of a different type of encephalomyelitis than the forms usually observed.\"\u003c\/p\u003e\n\n\u003cp\u003eJust \u003cstrong\u003ethirteen days later\u003c\/strong\u003e, the Viennese neurologist \u003cstrong\u003eConstantin von Economo\u003c\/strong\u003e (1876–1931) published his own article on what would become known as \u003cstrong\u003eencephalitis lethargica\u003c\/strong\u003e—a mysterious disease that caused sleepiness, eye movement disorders, and sometimes permanent Parkinsonism-like symptoms. A bitter controversy followed over who deserved credit for the discovery.\u003c\/p\u003e\n\n\u003cp\u003eHistorians note that Economo's description was documented by exceptional anatomo-pathological examinations and was probably more relevant. He indicated \"a precise and constant symptomatology\" in his first description, which \"undoubtedly explains why his work caught the attention of the medical public.\" Cruchet and his French colleagues \"more accurately showed the polymorphous symptomatology of the disease\" but did not initially seem to correspond to a well-defined morbid state. Economo also suspected—without being able to prove it—that lesions in the pre-optic area of the hypothalamus caused the sleeplessness (agrypnia) he observed in some patients. It was not until after World War II that the type of lesions Economo described would be interpreted as affecting an anatomical sleep induction centre in the brain.\u003c\/p\u003e\n\n\u003cp\u003eCruchet, for his part, could identify patients suffering from psychomotor slowing and somnolence following an influenza-like illness. He emphasised the variability of the disease's neurological signs and its progression, which was most often spontaneously favourable without treatment. However, the lack of means for biological and anatomo-pathological exploration limited him to clinical descriptions alone.\u003c\/p\u003e\n\n\u003cp\u003eCases of lethargy itself were nothing new; the condition had been described under various names by Albrecht von Hildesheim in 1695 and then by Angelo Dubini (1813–1902) in 1846. What was truly novel during World War I was the \u003cstrong\u003escale\u003c\/strong\u003e of the epidemic.\u003c\/p\u003e\n\n\u003ch2 id=\"vincent\"\u003eClovis Vincent: The Intrepid Neurologist\u003c\/h2\u003e\n\n\u003cp\u003eFew figures in wartime medicine were as daring—or as controversial—as \u003cstrong\u003eClovis Vincent\u003c\/strong\u003e (1879–1947). Born into a family of physicians in the region around Orléans in north-central France, he became an interne in 1903, studying under Fulgence Raymond, Achille Souques, and Babiński. He defended his thesis in 1910 and became a hospital physician in 1913.\u003c\/p\u003e\n\n\u003cp\u003eAlthough exempted from military service in 1900 for \"weakness,\" Vincent completed a short service in 1901–1902 as a medical student. He was mobilised on \u003cstrong\u003e2nd August 1914\u003c\/strong\u003e at age 35, serving as a médecin auxiliaire for the stretcher-bearers of the Fifth Army Corps. The famous surgeon Henri Mondor (1885–1962) described Vincent's battlefield reputation: \"He was already known throughout an entire infantry division for his reckless intrepidity and his singular personality.\"\u003c\/p\u003e\n\n\u003cp\u003eVincent treated the injured—French and German alike—without regard for danger. One night, he found himself metres from German lines, surrounded by grenade explosions, throwing himself into digging out soldiers buried alive by a mine explosion. Witness André Ravina (1892–1973) saw him pause, take out his watch, smile strangely, and exclaim: \"And to think that there are people who, at this time in Paris, are just leaving the theatre!\"\u003c\/p\u003e\n\n\u003cp\u003eIn October 1914, Vincent was assigned to the 46th infantry regiment and participated in the Battle of Vauquois during the winter of 1914–1915. During one attack, after all the officers of his battalion had been killed, the physician led the troops into battle, dragging hesitant soldiers forward while caring for the wounded. This heroic conduct earned him the \u003cstrong\u003eLégion d'Honneur\u003c\/strong\u003e and his first citation: \"An admirable officer and one admired by the entire regiment on the days from 28th February to 1st March; under intense bombing, bandaged those seriously wounded including one killed at his side by artillery fire; followed attacking troops to a heavily fortified position and headed up the sections which had lost their officers.\"\u003c\/p\u003e\n\n\u003cp\u003eIn April 1915, Vincent took over direction of the neurology centre of the ninth military region in Tours from Maxime Laignel-Lavastine (1875–1953). He was promoted to médecin major de 2e classe in January 1916. At Tours, he was \"struck by the specific characteristics of war-related hysterical phenomena: intensity, tenacity, tendency for relapse.\" Borrowing a principle from his teacher Babiński, he developed a method he believed was \"much more powerful and effective than the methods used up to that point.\"\u003c\/p\u003e\n\n\u003cp\u003eThis aggressive treatment method, nicknamed \u003cstrong\u003e\"torpillage\" (\"torpedoing\")\u003c\/strong\u003e by the soldiers who endured it, was designed to \"shock\" patients out of hysterical symptoms. It proved deeply controversial. Both soldiers and many of Vincent's physician colleagues objected to it. The situation reached a public crisis with the case of \u003cstrong\u003eBaptiste Deschamps\u003c\/strong\u003e, a soldier who refused torpillage and went before a military court in May 1916. Vincent left the Tours neurology centre following the widely publicised affair—not only because of objections to his therapy but also because his superiors refused to provide the new equipment he requested for his department, which had been set aside for persistent, difficult-to-treat cases of hysteria.\u003c\/p\u003e\n\n\u003cp\u003eEver the fighter, Vincent requested a return to the front and was assigned as a regiment physician to the 44th infantry battalion in April 1917, then the 98th infantry regiment in June 1917. He once again distinguished himself in battle, earning the \u003cstrong\u003eCroix de guerre\u003c\/strong\u003e with a second citation: \"20th August 1917; throughout the day on the battlefield, gave proof of a remarkable dedication, successively moving between all the emergency units of the front line, seeking out those units closest to the action, monitoring the transport of injured soldiers, and all of this in spite of the barrages and machine gun fire of the enemy.\"\u003c\/p\u003e\n\n\u003cp\u003eAfter a brief assignment to the Zuydcoote military hospital in November 1917, Vincent was sent to the military hospital at the Lycée Buffon in Paris on 28th January 1918, where he rejoined his mentor Babiński. He would play an active role in fighting the devastating Spanish influenza epidemic. Vincent always maintained that his experience as a front-line regiment physician gave him a credibility no one else possessed in interpreting hysteria attacks following shell explosions.\u003c\/p\u003e\n\n\u003ch2 id=\"sollier\"\u003ePaul Sollier: The Moderate Voice\u003c\/h2\u003e\n\n\u003cp\u003eIn sharp contrast to Vincent's aggressive approach stood \u003cstrong\u003ePaul Sollier\u003c\/strong\u003e (1861–1933), a respected neuropsychiatrist who advocated gentleness and empathy. After training under Désiré-Magloire Bourneville (1840–1909), Jules Dejerine, and Victor Cornil (1837–1908), Sollier became chef de clinique for mental diseases in 1891 under Auguste Voisin (1829–1898).\u003c\/p\u003e\n\n\u003cp\u003eIn 1897, Sollier founded a hydrotherapy facility in Boulogne-Billancourt, on the edge of the Bois de Boulogne west of Paris, where he experimented with new therapeutic methods—techniques now considered \u003cstrong\u003eprecursors of modern cognitive behavioural therapy\u003c\/strong\u003e. His most famous patient was the writer \u003cstrong\u003eMarcel Proust\u003c\/strong\u003e (1871–1922), treated in 1905.\u003c\/p\u003e\n\n\u003cp\u003eWhen World War I began, the 53-year-old Sollier was theoretically no longer subject to military obligations. He had completed his military service in 1880 in an infantry regiment. Yet he chose to enlist voluntarily, serving with distinction in the reserve army and the Territorial Army, reaching the rank of médecin major de 2e classe.\u003c\/p\u003e\n\n\u003cp\u003eIn April 1915, Sollier became director of the neurology centre of the 14th region in Lyon, attaining the rank of médecin major de 1ère classe. He organised the centre and its annexes across cities between Lyon and Grenoble. In addition to conventional departments for hydrotherapy, isolation, electrotherapy, and rehabilitation, he applied the principles of behavioural therapy he had developed before the war.\u003c\/p\u003e\n\n\u003cp\u003eSollier took an interest in all fields of neurology and neurosurgery. In 1918, he published a comprehensive treatise on war neurology that became a standard reference in the field. His training led him to a special interest in war-induced hysteria, but his approach was fundamentally different from Vincent's. Sollier adopted an \u003cstrong\u003eempathetic approach\u003c\/strong\u003e toward these patients. He called for returning to the therapeutic approach of Guillaume Duchenne de Boulogne (1806–1875), who used gentle faradisation (a mild form of electrical stimulation).\u003c\/p\u003e\n\n\u003cp\u003eFor Sollier, the hysteric was not a malingerer: \u003cstrong\u003e\"The true, complete simulation of nervous disturbances is very rare; exaggeration is much less rare.\"\u003c\/strong\u003e This view placed him in direct opposition to harsher methods and reflected a more compassionate understanding of soldiers' psychological suffering.\u003c\/p\u003e\n\n\u003ch2 id=\"legacy\"\u003eWhat This Means for Patients Today\u003c\/h2\u003e\n\n\u003cp\u003eThe work of these French neurologists during World War I left an enduring legacy that touches patients even today. Here are the most important takeaways:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGuillain-Barré syndrome\u003c\/strong\u003e, described by Guillain, Barré, and Strohl in 1916, remains one of the most important neurological emergencies.

The debates between Vincent and Sollier prefigure modern discussions about PTSD (post-traumatic stress disorder) and how best to treat psychological trauma—with compassion and evidence-based therapy versus harsh, confrontational methods.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEncephalitis lethargica\u003c\/strong\u003e research highlighted how a viral-like illness can affect the brain's sleep centres, contributing to today's understanding of sleep disorders and the links between infection and neurological disease.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThe importance of specialised neurological centres\u003c\/strong\u003e was proven during the war.

It was first described in October 1916 by Georges Guillain, Jean-Alexandre Barré, and André Strohl as 'radicular neuritis with hyperalbuminosis of the cerebrospinal fluid without cellular reaction.' It remains one of the most important neurological emergencies, and early recognition and treatment are critical.\u003c\/p\u003e\n\u003ch3\u003eHow is Guillain-Barré syndrome treated today?\u003c\/h3\u003e\n\u003cp\u003eModern treatments for Guillain-Barré syndrome include intravenous immunoglobulin and plasma exchange. These have dramatically improved outcomes. The fundamental clinical description from the war years still guides diagnosis. Early recognition and treatment are critical because the condition is one of the most important neurological emergencies. If you or someone you know develops sudden weakness, seek medical attention promptly.\u003c\/p\u003e\n\u003ch3\u003eWhat did doctors learn from brain injuries in World War I?\u003c\/h3\u003e\n\u003cp\u003ePierre Marie studied nearly 5,000 cases of skull injury at La Salpêtrière in 1915 and 1916. He found that cortical lesions, damage to the brain's outer layer, produce specific neurological deficits. This helped establish a foundation of modern neurology and neurosurgery. The concentration of patients in specialised centres accelerated research in ways that dispersed care could not match.\u003c\/p\u003e\n\u003ch3\u003eWhat was 'shell shock' and how was it treated?\u003c\/h3\u003e\n\u003cp\u003eShell shock referred to nervous problems following exposure to exploding munitions. Some doctors, like Clovis Vincent, used an aggressive method nicknamed 'torpillage' to shock patients out of symptoms. Others, like Paul Sollier, advocated gentleness and empathy, calling for mild electrical stimulation. Sollier argued that true simulation of nervous disturbances is very rare. These debates prefigure modern discussions about PTSD and its treatment.\u003c\/p\u003e\n\u003ch3\u003eWhat is encephalitis lethargica?\u003c\/h3\u003e\n\u003cp\u003eEncephalitis lethargica was a mysterious disease that caused sleepiness, eye movement disorders, and sometimes permanent Parkinsonism-like symptoms. It appeared in epidemic form during World War I. René Cruchet described cases in 1917, and Constantin von Economo published his own description thirteen days later. The condition highlighted how a viral-like illness can affect the brain's sleep centres, contributing to today's understanding of sleep disorders and infection-neurology links.\u003c\/p\u003e\n\u003ch3\u003eWhy are specialised neurological centres important?\u003c\/h3\u003e\n\u003cp\u003eDuring World War I, the concentration of expertise and patients in dedicated neurological facilities accelerated research in ways that dispersed care could not match. This lesson continues to shape how modern healthcare systems organise stroke units and specialised neurological services. Specialised centres allow doctors to see more cases, develop new tests, and improve diagnosis and treatment for conditions like spinal cord injuries and brain injuries.\u003c\/p\u003e\n\u003ch3\u003eWhat are the limitations of historical accounts like this?\u003c\/h3\u003e\n\u003cp\u003eHistorical records from wartime are often incomplete. Military archives, letters, and journals may not capture the full scope of clinical work, especially at the front lines. The encephalitis lethargica controversy shows how scientific credit can be difficult to assign. Descriptions of treatments like torpillage come from neurologists' perspective; patients' experiences complicate the picture. Modern diagnostic categories should not be imposed on historical patients.\u003c\/p\u003e\n\u003ch3\u003eWhen should a patient with Guillain-Barré syndrome seek a second opinion?\u003c\/h3\u003e\n\u003cp\u003eGuillain-Barré syndrome is a neurological emergency in which the immune system attacks the peripheral nerves, causing weakness and sometimes paralysis, and early recognition and treatment are critical. Because the diagnosis rests on a distinctive clinical picture first described in 1916, a second opinion can be valuable when the presentation is atypical, when the diagnosis is uncertain, or when treatment options such as intravenous immunoglobulin or plasma exchange are being weighed.
