INSTRUCTIONS TO THE AUTHORS

1. Language.
If the abstract is submitted in English, only one copy is required. If the abstract is submitted in Spanish or French, an additional copy translated to English must be sent.

2. Abstracts will be not shorter than 200 words and will not exceed 250 words.
A structured abstract should be organized by:
- Originals (free-topic communications, posters and Invited Conferences): Introduction, methods or case-report, results, and conclusions.
- Views & Reviews (Invited Conferences): Objective, development, and conclusions.

3. Key-words. The author must provide up to six key-words (both in English and in any of the other language of the Congress), in alphabetical order. Key-words should provide a clear reference of the content of the manuscript. Key words should be taken from Index Medicus (Medical Subject Headings) or, failing this, composed on the same principle.

4. Introduction. It should contain the background, purposes and reasons for doing the study.

5. Methods. It should describe clearly the selection criteria, the number and characteristics of the patients, and the design of the study. Sufficient information must be included to permit repetition of experimental work. When the manuscript refers to human beings it would be titled Patients and Method. Case-reports should be described clearly. Drug references should be done with generic (non commercial) names. Units and abbreviations of paraclinic and laboratory findings should be adjusted to international norms. It should be pointed the statistical procedure employed and the significance level established.

6. Results. These should be given concisely; the use of tables and figures to illustrate the same results will only rarely be allowed.

7. Discussion. This section should comment the most relevant conclusions of the study and should not repeat results. Clinical relevance of the results, limitations of the study, and references to previous similar works should be included in this section. Conclusions should be based only in the results derived from the work. Recommendations for future studies can be done.
8. Bibliography. References should be updated. We highly recommend the citation of manuscripts published in Spanish if considered relevant by the authors. References should appear as Arabic numerals in square brackets lined up with the text. Cite references in numerical order in the text. Authors should refer to the "Uniform requirements for manuscripts submitted to biomedical journals" (Rev Neurol 1997; 25: 795-803) for style and publication guidelines. The year of publication should follow the abbreviated name of the Journal, according to the system adopted by Index medicus. Papers that are "submitted" but not published yet may be mentioned as "in press" and should be included in the reference list stating the journal in which it is to appear. Personal communications are not allowed.

The following are sample styles:

    1. Journal articles. List all authors when there are six or fewer; when there are seven or more, list only the first three and add "et al."

    2. Monograph edited by Panel experts or Institutions.

    4. Book chapter

9. Tables. Tables should be brief and easily understood without referring to the text. The number of tables should not be more than one for every 600 words in the manuscript. Type each table, with a title, a legend and abbreviations, on a separate sheet. Use Arabic numerals to number tables in the order of their mention in the text. All tables must be double-spaced. If some Table had been previously published the author must obtain the reprinted permission and send it with the manuscript to the Scientific Secretary.

10. Figures. Figures must be sent apart from the manuscript (but with a clear reference of their position in the text). All figures should be labeled with the manuscript title, panel discussion assigned and author’s name. Figures should be numbered (Arabic numerals) in the order of their mention in the text.
Since Invited Conferences will be published in Revista de Neurología, all figures must be sent in agreement with the instructions for publication of that Journal. Briefly, photographs should be glossy bromide prints of good contrast, suitable for reproduction by lithography. We recommend an approximate size of 12x17cm, not larger than 20 x 25 cm (8" x 10"). Color photographs are only exceptionally published. Symbols, lettering, and numbering should be sufficiently large to remain legible after a figure has been reduced to fit the width of a single column. On the back of each figure, indicate with a post-it note, the name of the leading author, the figure number, the manuscript title and the top of the figure with an arrow. Do not print on the back of the figure. Avoid folding or tearing. Figures should be numbered (Arabic numerals) in the order of their mention in the text. Legends to figures should be double-spaced and must appear on a separate page indicating the title of the figure, and any observations or abbreviations, if needed. If some Figure had been previously published the author must obtain the reprint permission and send it with the manuscript to the Scientific Secretary.

11. Abbreviations. These are not allowed in the title of the manuscript. All abbreviations should conform to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (Ann Intern Med 1982; 96: 766-771). Any other abbreviation should be previously defined in the text when initially used.
