INTRODUCTION The history of neurology in Latin America developed in parallel with the leading European centers, most importantly in France and Germany, where most prominent Latin American neurologists were trained. Nevertheless, it is difficult to follow this puzzle of country-specific scattered data, which have hardly been included in international publications or were included in local journals without being referenced in bibliography indices. In fact, given lost records and the difficulties of publishing in Spanish in most international journals (Gibbs, 1995; Famulari, 2003) there are only limited data available on the history of neurology in some of these Latin American countries. Neurology in Latin America emerged toward the end of the 19th century, following the origin of the specialty in Europe and its official baptism with Charcot at the Salpeˆtrie`re Hospital in Paris. The first steps took place almost simultaneously in five countries: Argentina, Brazil, Uruguay, Chile, and Peru. In the other countries, the development of neurology took place later in the 20th century. In all cases, one can discern three fundamental stages: 1. Stage of neurology as part of internal medicine: doctoral theses and publications about neurological topics are found early in the history of medicine, but only within internal medicine. 2. Foundation stage of clinical neurology: under the typical European influence, mainly French, the first neurologists appear. With the founding of chairs of neurology, the birth of scientific societies, and specialized journals, clinical neurology consolidated. *

3. Stage of neurological sub-specialties: in the more recent North American-influenced years, there is a new paradigm favoring the atomization of the sciences. Specialists in epilepsy, headache, stroke, dementia, among others, appear.

SOUTH AMERICA Argentina The history of neurology in Argentina began in 1827 at the University of Buenos Aires School of Medicine (university names will be given in English throughout this chapter) with a doctoral thesis about epilepsy (Epilepsia: su naturaleza y curación) submitted by Martı´n Garcı´a (Bardeci, 1948). The foundation stage started in 1885, with the creation of the Hospital San Roque de Buenos Aires’ first nervous diseases ward. Its first chair, Jose´ Marı´a Ramos Mejı´a, had a solid humanistic education; he was a writer, a sociologist, a person of science, and an outstanding public man. His thesis was Apuntes clínicos sobre el traumatismo cerebral (Clinical Notes on Traumatic Brain Injury), including two reports on cranial trepanations. In 1887, only 5 years after Charcot was awarded the chair of neurology in Paris, Ramos Mejı´a became the first professor of neurology in South America, this being at the University of Buenos Aires. In his double capacity as chair and professor, he was a pioneer of neurology in Argentina (Somoza and Gualtieri, 1998). Ramos Mejı´a was the most important positivist in Argentina. His classical articles, more sociological and psychiatric than neurological, were La neurosis en los hombres públicos de la historia argentina

(Neurosis in Public Men in the History of Argentina), Las multitudes argentinas (The Argentinian Masses) and Estudios clínicos sobre las enfermedades nerviosas y mentales (Clinical Studies on Mental and Nervous Diseases). In 1888, Federico Papi, an Italian neurologist and neuropathologist, took over the Department of Neurology at the University of Co´rdoba School of Medicine, which he headed until 1890, when he returned to Italy (Brunetti and Palacio, 1998). Three assistants collaborated with Ramos Mejı´a at the University of Buenos Aires and were essential for the development of neurology in Argentina. Christofredo Jakob specialized in neuropathology. He trained in Germany with Strumpell and published an atlas of the nervous system with him. Jakob is considered the founder of neuropathology in Argentina and was important in the systematization of brain slicing and for efforts to study the myelin sheath (Hano´n, 1956). Jose´ A. Este´vez, in contrast, favored a clinical approach. He was hired in 1913 and became known for his bedside clinical acumen. He published articles about facial progressive hemiatrophy, epidemic meningitis, Sydenham’s chorea, and hydatid cysts. Hydatid disease, endemic in South America, is a parasitic infestation caused by Echinococcus. Symptoms depend upon where hydatid cysts form in the brain. Seizures and headaches are common symptoms. The third important assistant was Jose´ Ingenieros, who made sociological contributions. In 1924, Mariano Alurralde succeeded Este´vez, and he gave his lectures an anatomo-pathologic orientation (Somoza and Gualtieri, 1998). Alurralde wrote articles about neurosyphilis. In Este´vez, Jakob and Alurralde’s times, the focus was on anatomy and histopathology; unsubstantiated opinions not backed by hard data were no longer as important as they had been in Ramos Mejı´a’s era (Somoza and Gualtieri, 1998). In 1941, Vicente Dimitri was designated professor of neurology at the University of Buenos Aires. Dimitri was the first physician with neuropathological and neurological training, which he acquired with Jakob and by visiting European hospitals. With Dimitri, neurology par excellence began (Figini, 1964). He greatly influenced those who surrounded him, including Jose´ Pereyra Ka¨fer, who became chairman of the Hospital Ramos Mejı´a Neurology Service (formerly Hospital San Roque) and then took over as professor of neurology at the University of Buenos Aires. In 1952, he founded the Sociedad Neurolo´gica de Buenos Aires, which later became the Sociedad Neurolo´gica Argentina (SNA), a part of the World Federation of Neurology (WFN). During the 1970s, the stage of neurological sub-specialties began, reflecting a greater North American influence (Somoza and Gualtieri, 1998). The new era

at the University of Buenos Aires Department of Neurology began with Roberto E.P. Sica, neurologist and neurophysiologist, whose most important articles were on motor neuron disease and on Chagas’ disease (also called American trypanosomiasis). The latter is a mammalian disease occurring only in the Americas. It is caused by the protozoan Trypanosoma cruzi, transmitted to humans in most cases by insects of the Triatominae subfamily, known in Argentina as “vinchuca.” Sica became chairman of the Hospital Ramos Mejı´a Neurology Service, the most recognized department of neurology in Argentina. FLENI (Fundacio´n para la Lucha contra las Enfermedades Neurolo´gicas de la Infancia) Neurological Institute in Buenos Aires dates back to 1959, when the creator Rau´l Carrea (a neurosurgeon) returned after several years in the US. The Centre for Neurological Research was the first scientific research laboratory to open in 1968 in the “Ricardo Gutierrez” children’s hospital, but it was closed in 1976. In 1978, Carrea opened the first Computed Tomography Center in Latin America at FLENI. At that point, he invited Ramo´n Leiguarda (a neurologist trained in London) to join him. In 1978 Carrea passed away unexpectedly and Leiguarda followed his work in maintaining and developing FLENI. Nowadays it is the most important non-profit neurological organization in Latin America, delivering preventive medicine, diagnostics, health care services, and research on neurological disease (www. The first journal in Argentina was the Revista Neurológica de Buenos Aires created by Dimitri in 1936 (Fig. 49.1). In 1972, Pereyra Ka¨fer renamed it the Revista Neurológica Argentina with He´ctor Figini as its first editor. This journal is still published. Among the reviews and case studies in the early period of the journal, we find (in Spanish) Jakob’s “Contribution to pituitary neoplasm histogenesis” (Jakob, 1936), Dimitri’s “Retinal telangiectasis, angioma of the protuberance and cerebellum glioma” (Dimitri et al., 1936), and notices and summaries of international congresses and lectures. These notices and summaries were very important, since few physicians had a good command of non-Spanish languages and even fewer had access to international journals.

Brazil The history of neurology in Brazil centered on developments in Rio de Janeiro and Sa˜o Paulo, and each will be treated in turn. Neurology in Rio de Janeiro has been considered the foundation of Brazilian neurology. In 1878, Joa˜o Vicente de Torres Homem wrote the first Brazilian book exclusively devoted to neurology, Lições Sobre as

Molestias do Sistema Nervoso (Lessons about Nervous System Diseases) (Gomes, 1999a). The University of Rio de Janeiro School of Medicine created the first Brazilian department of neurology in 1912. Its first full professor was Anto˜nio Austrege´silo Rodrı´gues Lima, a politician, a writer, and a skilled physician, now considered Pai da Neurología Brasileira (the father of Brazilian neurology). He was the first to study movement disorders in Brazil, publishing several works on this subject, primarily in Revue Neurologique and L’Encéphale, including an alternate to the Babinski sign (Fig. 49.2), and the first description of a post-traumatic dystonia (Teive et al., 1999). In 1944, Deolindo Augusto de Nunes Couto took over as chairman and consolidated Brazilian neurology. In 1946 he founded the Instituto de Neurologı´a da Universidade Federal do Rio de Janeiro, with extensive research activity in neurology, neurophysiology, and neurosurgery. This institute, later renamed Instituto de Neurologı´a Deolindo Couto da Universidade Federal do Rio de Janeiro, became the international face of Brazilian neurology. His first assistants were Antoˆnio Rodrı´gues de Mello, Ismar Fernandes, and A´lvaro Jose´ de Lima Costa, who published a book on neuroparasitosis in 1967. Neuropathology was further developed by Paulo Elejalde, followed by Alexandre

Alencar, both known for Chagas’ disease research. Bernardo Henrique de Nunes Couto headed the Institute and was followed by Clo´vis Oliveira, He´lcio Alvarenga, and Gianni Temponi (Gomes, 1999a). In 1925, Enjolras Vampre´ was appointed by the School of Medicine of the University of Sa˜o Paulo to take over the Department of Psychiatry and Neurology. Vampre´, through his training at the Salpeˆtrie`re, introduced the fundamentals of French neurology to Sa˜o Paulo and is considered the founder of the Sa˜o Paulo School of Neurology (Reima˜o and Alonso Nieto, 1996; Morato-Leite, 1999). In 1935, the Department was divided into Psychiatry and Neurology. Successive generations of neurologists and neurosurgeons at the Sa˜o Paulo school were associated with Vampre´. They include Adherbal Tolosa, Paulino Watt Longo, Oswaldo Lange, and Carlos Gama (MoratoLeite, 1999). Following a competitive examination, Tolosa was appointed chair of neurology at the University of Sa˜o Paulo. He wrote several semiotic articles (including studies on the cremasteric reflex) that were published in local journals. Longo became the chair of the Paulista School of Medicine, and Lange remained clinical chief of the University of Sa˜o Paulo School of Medicine until 1969. Lange was known outside Brazil for his activity as director of the Arquivos

CLINICAL NEUROLOGY IN LATIN AMERICA 805 Jacinto de Leo´n aspired to be appointed to the Neurology Department of the University of Montevideo, although this never happened (Wilson, 1991, 1992). Jose´ Verocay, another important physician at this time, provided a good neuropathological description of neurofibromatosis or von Reckinghausen’s disease, now also known as Verocay neurinoma (Verocay, 1910). In 1925, the creation of the Department of Neurological Diseases was approved in the School of Medicine of Montevideo, with Ame´rico Ricaldoni as its chairman. Ricaldoni’s acceptance was conditional on financial assistance and the creation of a teaching and research facility. Subsequently, the government created the Instituto de Neurologı´a de Montevideo (in 1927; Fig. 49.3), and Ricaldoni was designated Director of the Institute and Professor of Neurological Disease. This was the first neurological institute in Latin America – preceding the Montreal Neurological Institute by several years. Ricaldoni published articles in journals from Uruguay and Argentina, wrote about Landry’s palsy in Archives Générales de Médicine de Paris, and bilateral cranial nerve VI and VII palsies in the Revue Neurologique. He died in 1928. The creation and abrupt growth of his institute, however, did not mean the birth of neurology as a specialty in Uruguay; the practice of neurology, other than for Jacinto de Leo´n, continued within internal medicine. At the beginning of 1937, Alejandro Schroeder, a neurologist and neurosurgeon, was appointed university professor and institute director. In 1925, he traveled to Germany to work with Jakob and Nonne in Hamburg, and Fo¨rster in Breslau. He then wrote the first book of neurology in Uruguay. Since Schroeder took over, the Institute – renamed Instituto de NeuroUruguay logı´a Prof. Dr. Ame´rico Ricaldoni – has been ranked Neurology in Uruguay started with Francisco Soca, very highly in South America. who graduated in Paris at the end of 1888 with his docThe Institute’s third director, Roma´n Arana In˜iguez, toral thesis Étude clinique sur la maladie de Friedtook over in 1957 and was moved to the second floor of reich (Clinical Study of Friedreich’s Disease) the Hospital de Clı´nicas (Wilson, 1991, 1992).

Antoˆnio Branco Lefe`vre, Hora´cio Martins Canelas, Antoˆnio Spina Franc¸a Netto, and Gilberto Scaff continued this school (Reima˜o and Alonso Nieto, 1996; Morato-Leite, 1999). Antoˆnio Branco Lefe`vre was recognized as the father of child neurology and neuropsychology for his research and articles (Lefe`vre, 1999). Martins Canelas, who did research on Wilson’s disease, wrote articles in Brazilian journals and in international journals, such as Journal of Neurology, Neurosurgery and Psychiatry and Acta Neurologica Scandinavica. The Academia Brasileira de Neurologia was created in 1962, and Deolindo Couto was its first president. The first neurological journal published in Brazil was Neurobiologia, created in 1938 by Ulysses Pernambucano in northern Brazil (Recife). The first articles included not only theory; they incorporated clinical research in psychology, neurology, and psychiatry (Codeceira, 1999). In 1943, Tolosa, Longo, and Lange created – under Oswaldo Lange’s direction – the Arquivos de Neuropsiquiatria in Sa˜o Paulo. This is the most important journal of neurosciences in Latin America and it is found in Index Medicus, WHO, Bireme, Lilacs, and Latindex (Spina Franc¸a, 1999). In 1949, in Rio de Janeiro, Deolindo Couto created the third neurological journal to come out of Brazil, Jornal Brasileiro de Neurologia, renamed Revista Brasileira de Neurologia in 1983 (Gomes, 1999b).

Arana retired in 1974, the year he decided to separate neurology from neurosurgery. He´ctor Deffe´minis was appointed professor of neurology. After his retirement, he was succeeded by Marı´a A. Rebollo and, in 1987, by Carlos Chouza (Wilson, 1991, 1992). The Sociedad de Neurologı´a y Neurocirugia de Montevideo was set up in 1939 with Schroeder as its first president. In 1951, the Acta Neurológica Latinamericana was created. The objective was to have a common Latin American neurological journal, preserving the language and making it easier for Spanish-speaking neurologists to publish their work (Wilson, 1991).

Peru Neurology in Peru took its first steps with Carlos Krumdieck, who in 1928 spent a year at the Salpeˆtrie`re. When he returned from Paris, he taught neurology until 1930, but increasingly devoted himself to pediatrics. Juan B. Lastres, who was chief of clinical neurology between 1931 and 1934, later became professor of the history of medicine. The first true neurologist was Oscar Trelles Montes, considered the “father of neurology of Peru.” He worked in Paris from 1930 to 1935, where he acquired neurological training under Jean Lhermitte. He published 35 scientific

papers in collaboration with Lhermitte. He also published a notable book, Précis d’Anatomophysiologie Normale et Pathologique du Système Nerveux, with Franc¸ois Masquin (Cubas, 2002; Escalante Sa´nchez, 2004). In 1935, he returned to Peru and in a few years he joined the elite of doctors in Latin America. In 1940, he was recognized as professor of neuropathology at the Universidad Nacional Mayor de San Marcos School of Medicine (Escalante Sa´nchez, 2004). By this time, he was attending the Refugio de Incurables, a ward under the administration of the Beneficencia Pública of Lima (Escalante Sa´nchez, 2004). The “Refugio” was renamed Hospital Santo Toribio de Mogrovejo thanks to his efforts (Escalante Gavancho, 2004). During the 30-year leadership of Trelles, almost all neurologists in Peru had this hospital as their alma mater. In 1941, Trelles co-authored (with Lazartes) a book titled Cisticercosis Cerebral. Brain cysticercosis is an endemic infection in Latin America caused by the pork tapeworm, Taenia solium (Escalante Gavancho, 2004). Infection occurs when the tapeworm larvae enter the body and form cyst cerci. Neurological symptoms of cysticercosis depend upon where and how many cyst cerci are found in the brain. In 1963, the Hospital Santo Toribio was recognized as Hospital Neurolo´gico and in 1981 it became the



Instituto de Ciencias Neurolo´gicas (Institute of Neurological Sciences) of Peru, headed by Silvio Escalante Sa´nchez, Ernesto Rı´os Montenegro, and then Luis Trelles Montero (son of Oscar Trelles Montes) (Cubas, 2002). The Sociedad de Neuropsiquiatrı´a y Medicina Legal of Peru was created in 1938 by Honorio Delgado, a prominent psychiatrist, and Oscar Trelles Montes. In 1945, it was renamed the Sociedad Peruana de Psiquiatrı´a, Neurologı´a y Neurocirugı´a. As time went by, the Sociedad Peruana de Neurocirugı´a and the Sociedad Peruana de Psiquiatrı´a were divided, so the Sociedad Peruana de Psiquiatrı´a, Neurologı´a y Neurocirugı´a consisted largely of neurologists. In 1990, it became the Sociedad Peruana de Neurologı´a. In 1937 Honorio Delgado and Oscar Trelles cofounded the Revista de Neuropsiquiatría, which continues to publish quality scientific articles. The Revista Peruana de Neurología was created in 1995 under Jose´ del Carmen’s direction, and it is the official journal of the Sociedad Peruana de Neurología.

Chile Neurology in Chile goes back to 1869, with Jose´ Ramo´n Elguero del Campo, the first professor of mental diseases of the University of Chile. Three years later, however, he devoted himself to medical pathology (Escobar, 2000). The chair remained unoccupied until 1882, when Carlos Sazie´ Heredia took over. Sazie´’s neurological training started when he won a government scholarship to specialize with Magnan, Voisin and Charcot in France (from 1874 to 1879). Fe´lix Vulpian sponsored his doctoral thesis on intellectual problems of aphasics. Sazie´ taught neuropsychiatry at the Hospital San Juan de Dios and then at the Hospital San Vicente de Paul until he was dismissed in 1891, following political problems (Escobar, 2001). In 1892, his disciple Augusto Orrego Luco (Fig. 49.4) took over as professor of nervous diseases at the University of Chile. Orrego Luco graduated in 1873 with a thesis on Alucinaciones mentales (Mental Hallucinations). Trained in France by Charcot, he published in the Iconographie de la Salpêtrière. In 1902 he wrote the book (translated as) Hysterical Hemiplegia and Organic Hemiplegia, in which differences between hysterical and organic symptoms were discussed. He was the most prominent figure in Chilean neurology during the second half of the 19th century, and was nicknamed the “Charcot of America” (Escobar, 2002a). In 1907, Orrego Luco retired and his chair was taken over by his disciple, Joaquı´n Luco Arriagada. The school decided to divide the department, and psychia-

try and neurology were coordinated by his assistants, Oscar Fontecilla and Hugo Lea Plaza, respectively. Luco Arriagada was also trained in Europe, in his case by Babinski, showing once again the influence from the French school. In 1925, he created the Hospital del Salvador Neurology Service. He began to serve as clinical chief at the Manicomio Nacional (Neuropsychiatric Hospital) in 1931. When Luco Arriagada retired, Lea Plaza was made chair of neurology at the University of Chile and Jorge Oyarzun became chief of neurology at the Hospital del Salvador (Escobar, 2002b). In 1929, the Hospital San Vicente de Paul’s Neurology Service was created in Santiago, and Oscar Fontecilla took over as chairman. Lea Plaza was succeeded by Guillermo Brinck, Emilio Morales (a neurosurgeon) and then Archibaldo Donoso. At the Hospital del Salvador, he was followed by Jorge Gonza´lez Cruchaga. Later on, the teaching and clinical care sections separated. Alfonso Asenjo Go´mez, trained in the United States by Walter Dandy and in Germany by Toennis, stimulated the creation of the Chilean Service of Neurosurgery. Asenjo worked with He´ctor Valladares, Carlos Villavicencio, Mario Contreras and A. Lepe. In 1953, the Instituto de

Colombia Miguel Jime´nez Lo´pez, who specialized in psychiatry and internal medicine in France, was the first to lead the National University’s Department of Mental and Nervous Diseases (Rosselli and Otero, 2000). By this time, Luis Lo´pez de Mesa, who would become Professor, had trained in neurology, psychopathology and neuropsychology at Harvard (Rosselli, 1985). In the first half of the 20th century, several professors of the National University were showing an interest in neurological diseases, among them Pablo A. Llina´s, Alfonso Uribe Uribe, and Edmundo Rico Tejada (Rosselli and Otero, 2000). The true foundation stage of neurology started with Andre´s Rosselli Quijano (Fig. 49.5), who in 1954 traveled to the Massachusetts General Hospital to study neurology. In 1956, he collaborated in the foundation of a neurology unit annexed to the Neurosurgery Department at Hospital Militar Central de Bogota´ (Rosselli, 1985; Rosselli and Otero, 2000). In 1961, Ignacio Vergara founded the Hospital San Juan de Dios Neurology Service and Jaime Potes founded the Hospital Universitario Del Valle Neurology Service. The first Hospital San Vicente de Paul Department of Neurosurgery and Neurology was created by the neurosurgeon Ernesto Bustamante. Jorge Holguı´n, who trained in France, created the first neuropediatrics service in Medellı´n in 1965 (Rosselli and Otero, 2000). The Sociedad Neurolo´gica de Colombia, which included both neurosurgeons and neurologists, was created in 1963. Neurologists decided to become independent in 1982, creating the Asociacio´n Colombiana de Neurologı´a. In 1985 the journal Acta Colombiana de Neurología was founded (Rosselli and Otero, 2000).


Bolivia Neurology in Bolivia had largely been the domain of neurosurgeons, and it was not until the second half of the 20th century that neurologists took a more active role. In 1966, the Sociedad de Psiquiatrı´a, Neurologı´a y Neurocirugı´a de Bolivia was at its height, with formal and regular meetings. There were three groups that catalyzed these institution activities, and they were led by Jose´ Marı´a Alvarado, from psychiatry, and Mario Michel Zamora and Hugo Rodrı´guez Serrano, two neurosurgeons who covered neurology and neurosurgery. The only two neurologists then in the city of La Paz had neither independent services nor society affiliations (Trigosso, 2003). In 1975, the Sociedad Boliviana de Neurologı´a was created. The board of directors was constituted by Mario Barraga´n and Adria´n Trigo (Trigosso, 2003). Inactivity led to the creation of a new leadership with Harry Trigosso as president, Luis Fernando Zegada as vice-president, and Humberto Molina as general secretary (Trigosso, 2003). After the Hospital de Clı´nicas and Hospital Obrero neurology and neurophysiology services were created, more neurologists began to be trained in Bolivia (Zegada, 2003). The Sociedad Boliviana de Neurologı´a was itself created in 1975.

Ecuador In 1960 the Sociedad Ecuatoriana de Neurologı´a, Neurocirugı´a y Ciencias Afines was created in Ecuador. Its founding president was Alfonso Martı´nez Arago´n. Until 1967, neurology in Ecuador was practiced within internal medicine and neurosurgery. Rafael Vargas Ortiz, the first neurologist, returned to the country that year, after being trained at the Centro Me´dico Nacional de Me´xico. In 1974 Toma´s Alarco´n, who founded the Hospital Regional de Guayaquil’s Neurology Service, returned from Mexico, and in 1975 Marcelo Cruz, who developed the Hospital Carlos Andrada Marı´n’s Neurology Service, returned from the USA. In 1982 the Sociedad Ecuatoriana de Neurologı´a became a WFN member (Leo´n de Ponce, 1988).

broke away to start a separate organization, the Academia Mexicana de Neurologı´a (http://www.neurologia. The first journal published at the INNN was the Revista del Instituto Nacional de Neurología y Neurocirugía, created in 1966, with Gu¨ido Belsasso and Francisco Escobedo as its first editors. In 1980, it was renamed Archivos del Instituto Nacional de Neurología y Neurocirugía and, in 1996, it was further renamed Archivos de Neurociencias (Escobedo and Corona, 2004). The Revista Mexicana de Neurociencias was created in 2000 under Lilia Nun˜ez Orosco’s direction and is the official journal of the Academia Mexicana de Neurologı´a (2006).

Puerto Rico The formal history of neurology started in Puerto Rico in 1958, when Luis Sanchez Longo was hired by the School of Medicine of Puerto Rico to start training in clinical neurology. Rosa Fiol, Iva´n Pe´rez Nazario, and Judith Roman were among his collaborators. In 1968 the Academia Portorriquen˜a de Neurologı´a was founded (Leo´n de Ponce, 1988).

Dominican Republic The Instituto Dominicano de Seguros Sociales Neurology Service was taken over by Mario Tolentino upon

his return from France in 1957. In 1965, the Hospital Moscoso Puello Neurology Service started under Juan Santoni. A year later, the Sociedad Dominicana de Psiquiatrı´a, Neurologı´a y Neurocirugı´a was created. In 1982 Psychiatry became independent, resulting in the Sociedad Dominicana de Neurologı´a y Neurocirugı´a (Leo´n de Ponce, 1988).

Cuba Neurology started in 1925 in Cuba, with the creation of the University of Havana Department of Neurology and Psychiatry and the birth of the Sociedad Cubana de Neurologı´a. But despite advances in neurology and neurosurgery, these disciplines were not officially recognized as specialties for many years. In 1960, when the University of Havana School of Medicine’s Department of Functional Neuroanatomy was created, there were only three neurologists practicing the specialty. With the aim of regrouping existing resources, the Department of Public Health created the Hospital de Neurologı´a, which opened in 1962. This institution provided nationwide neurological care and allowed Cuba to start a postgraduate teaching program. Five years later, it was renamed Instituto de Investigacio´n de Neurologı´a (Severa Ortega and Lo´pez Espinosa, 1997).



PAN AMERICAN CONGRESSES The idea of organizing a Pan American congress that would meet every 4 years was initially conceived within the framework of the World Federation of Neurology. The first Pan American Congress of Neurology was held in October 1963, in Lima, chaired by J. Oscar Trelles Montes (Fig. 49.7), who was then the Prime Minister of Peru. Official languages were Spanish and English. A.E. Walker, P. Bailey, R. Garcin, and F. Lhermitte were given the decoration Comendador El Sol del Peru by the President of the Republic, Belaonde Terry. The Second Pan American Congress was held in October 1967 in San Juan de Puerto Rico under the direction of Luis P. Sanchez Longo (Culebras, 1998). Subsequent congresses have since been held in Sa˜o Paulo (1971), Mexico City (1975), Caracas (1979), Buenos Aires (1983), San Juan, Puerto Rico (1987), Montevideo (1991), Guatemala City (1995), Cartagena, Colombia (1999), and Santiago, Chile (2003).

CONCLUSION The consistent and long-standing admiration for European training led to the birth of neurology as a discipline in some South American countries, namely Argentina, Chile, Uruguay, Brazil and Peru (Fraiman, 2000). This was followed by greater interest in North American training, which led to further developments in these countries and the start of the specialty in others. Among the most significant landmarks are: ●

The first neurology service in South America, which was created in 1885 at the Hospital San Roque de Buenos Aires and headed by Jose´ Marı´a

Ramos Mejı´a, who took over as professor of neurology at the University of Buenos Aires School of Medicine in 1887. ● The first institute of neurology in Latin America, the Instituto Neurolo´gico de Montevideo, created in 1926 under Ame´rico Ricaldoni’s direction. ● The creation of the most important Latin American journal, the Arquivos de Neuropsiquiatria from San Pablo, started in 1943 and it is still in existence. Unfortunately, the lack of access to scientific, Englishwritten and indexed publications has limited what has come out of Latin America, as have clinical demands and additional responsibilities of neurologists in official positions. Even today, articles written in Spanish are not considered by many international journals, most of which will only accept articles in English (Famulari, 2003). In a recent article published in Scientific American, which is appropriately titled “Lost Science in the Third World,” Gibbs (1995) wrote that investigators who want to become known outside of their own countries are strongly advised to publish in English, despite the fact that Spanish is spoken by more than 400 000 000 individuals worldwide (Famulari, 2003). The major research contributions from Latin America have thus far been those related to regional endemic diseases. From Brazil and Argentina, there have been important studies on Chagas’ disease; neurologists from Peru, Ecuador, Mexico and Colombia have researched cysticercosis; Venezuela stands out for genetic studies of Huntington’s disease; while retrovirus-induced neurological diseases have been studied in Panama. In the last 10 years, “globalization” has been positive for Latin American countries, as cooperative projects among them, as well as with first world countries, are now resulting in a more rapid development of Latin American neurology. This review was aimed at giving an overview of the initial stages of neurology in the Latin American world, highlighting the setting in which it was developed, who its pioneers were, how it was perceived locally and elsewhere, and developments in care, teaching, communications, and research. Given the space constraints, interested readers are encouraged to explore this subject further, possibly beginning with the references that follow.
