Keywords: internet; computer communication networks; neurology
The internet has become inescapable and increasingly essential in the everyday practice of neurology, largely because of the unparalleled medical resources on the world wide web (www). The ebb and flow of internet content calls for an update of older reviews of neurology and neuroscience resources.1,2
Rather than attempt a comprehensive summary, which is precluded by the proliferation of the internet,3 we have distilled internet content down to a manageable list of high quality portals for easy reference (table 1
). Uniform resource locators (URLs) are provided in the text if they are not mentioned in table 1.

Portals (also known as directories) are more reliable gateways to smaller selections of neurology resources because they are repositories of websites chosen or edited by humans for their quality. Google’s directory yields a mere 1850 websites using the same search criterion, and the websites are ranked by their perceived order of relevance.
Neurology portals
Neurologists and their patients are likely to find that portals specifically dedicated to neurology have a higher yield of pertinent websites than general directories. Neurology portals are distinguished from each other by various attributes including the comprehensiveness of their selection of websites, any bias in their compilation (in language, country of origin, funding, or disease category), the sophistication of software for searching the directory, and their presentation.
Recognising that readers are likely to use at most a handful of portals to direct their further browsing, we have been rather selective. Although the dot.com world is now relatively impoverished, forcing medical website developers to take recourse to advertising (especially from the pharmaceutical industry), we have tried to avoid recommending sponsored sites because they are unsightly and may be biased in their content. Despite the global nature of the internet, reviews of www resources are inevitably biased towards the authors’ country/continent of origin,2 and we suspect that ours is no exception.
Evidence based neurology portals
The Trip database is perhaps the most user friendly evidence based resource for neurologists. It is dedicated to bringing together all the evidence based healthcare resources available on the internet, and has a dedicated neurology "clinical area" which issues monthly updates that can be received by email. The Trip database includes coverage of the Cochrane Library, which has review groups dedicated to dementia and cognitive impairment, epilepsy, movement disorders, multiple sclerosis, neuromuscular disease, and stroke. Although the Cochrane Library operates on a subscription basis, free access is provided to low income countries, and many countries have arranged national provisions (www.update-software.com/cochrane/provisions. htm); for example, in England the full text of the library can be accessed through the National Electronic Library for Health (www.nelh.nhs.uk). The Cochrane neurological network (www.cochraneneuronet.org) functions as a link between neurologists and the Cochrane collaboration.
Guidelines for the practice of clinical neurology are not as yet united on one website, presumably because they tend to vary by region. The American Academy of Neurology (AAN) practice guidelines, which are kept updated, are freely available as pdf files on the AAN website. Other
high quality guideline repositories, not dedicated to clinical neurology, are the Scottish Intercollegiate Guidelines Network (www.sign.ac.uk) and National Guideline Clearing House (www.guidelines.gov).
General neurology portals
Without doubt the single most useful directory for neurologists is Neurosciences on the Internet. This website was established in late 1994 and it is strong on clinical neuroscience (including lists of other portals, disease related websites, patient organisations, mailing lists and discussion groups, educational resources, and useful software), although it has a slight north American bias.1,8 Other directories simply do not compare, so we suggest it should be the starting point for a survey of www resources in any particular area of neurology. While many websites devoted to particular categories of neurological disorder are worthy of mention (for example, www.wemove.org, dedicated to worldwide education and awareness for movement disorders), the majority are indexed by www.neuroguide.com.2
Journals
Almost every neurology journal has a website that can provide the full text of latest and recent issues. Exceptionally, only abstracts or tables of contents are available. Table 2 lists a small selection of clinical neurology journals, ranked by their impact factor; a more complete list is available from Neurosciences on the Internet and from PubMed’s journal database (www.pubmed.org). Most online journals are reproductions of their print counterparts. However, some peer reviewed journals only exist in electronic format, BioMed Central Neurology being the main example (www.biomedcentral.com/bmcneurol). One of the many advantages of the electronic format is the cross referencing of bibliographies using citation linking backbones.

e-Textbooks
There are two www based general neurology textbooks.9 eMedicine Neurology is a North American multiauthored work which is freely accessible with registration, searchable, well designed, and comprehensive. MedLink Neurology is a subscription only north American electronic textbook (available on the www and a CD-ROM updated quarterly), which also includes neurosurgery topics, videos, and a discussion board, but it costs at least $299 per year. The Neuromuscular Diseases Textbook is an unrivalled speciality resource, which provides up to date, comprehensive, intuitively indexed medical and patient information.10
Many of the resources above offer text and picture content suitable for creating lectures. Additional teaching resources include www.neuroexam.com, which illustrates the various stages of the neurological examination with streaming video. Neurologists wishing to test their knowledge on a regular basis can attempt to diagnose the Baylor College of Medicine case of the month, using the history and examination provided with an interactive battery of tests, and then return to the website the following month for the dénouement (www.bcm.tmc.edu/neurol/case.html).
News and discussion
NeurologyLinx is a website dedicated to providing news about both general and specialised neurology. Although the website is sponsored its advertisers do not influence content. News is updated daily on the website and in email bulletins, which mostly comprise information from journals and conferences.
Newsgroups offer an often unrestricted, interactive, www based means of exchanging news and (mostly) views.4 At the time of writing, the index of newsgroups—Google Groups (http://groups.google.com)—dating back to the Usenet discussion groups of 1981, did not list a dedicated neurology group, although at first glance bionet.neuroscience appeared to qualify. However, bionet.neuroscience contained around 29 500 discussion threads at the time of writing, most of which were unscientific, unsurprisingly generating a thread devoted to the creation of a scientific neuroscience newsgroup. There are newsgroups dedicated to particular diseases (for example, sci.med.diseases.als, sci.med.diseases.alzheimer, sci.med.diseases.lyme, and sci.med.diseases.mult-sclerosis), although neurologists are unlikely to find them informative. Some patients may benefit from discussions with others in the alt.support.disorders.neurological newsgroup.
Email discussion lists provide a more secure forum for neurologists to discuss professional issues by email. One of the longest established lists of this nature is the Neurologist Discussion List, vetted by a neurologist at the medical college of Georgia; members admitted to this list can control the frequency and content of emails updating them about ongoing discussions. Neurosciences on the Internet (www.neuroguide.com/neurolist.html) has compiled the contact details of many other email discussion lists (ranging from special interests in neurology, to paediatric neurology and clinical neurophysiology).
Patient information
Portals supplying patient information of uniformly high quality about the whole breadth of neurological diseases are hard to find, but the United States’ National Institute of Neurologic Disorders and Stroke (NINDS) comes close. The National Organisation for Rare Disorders (NORD) is a useful supplement to the NINDS website, especially for physicians based in the USA. MEDLINEplus (www.nlm.nih.gov/medlineplus/neurologicdiseasesgeneral.html) provides comprehensive patient information (mostly from the NINDS website), with further links to news, diagrams, research, organisations, and medical dictionaries. In the United Kingdom, the Neurological Alliance has collated links to the major patient support organisations, one of which is the Brain and Spine Foundation that publishes a growing number of well written and freely downloadable information leaflets.
Patients’ further need for communication and discussion can be fulfilled in disease specific online support groups through some of these websites. Where this is lacking, many patients—particularly those in the USA—join the www based BrainTalk communities or the Massachusetts General Hospital neurology chat rooms, to interact with nearly 55 000 others about general and specific neurological conditions.
