title: Neurological disorders and travel.
abstract: Travel is associated with a number of neurological disorders that can be divided into two categories: (1) Neurological infections including encephalitides, neurotuberculosis, neurobrucellosis, cysticercosis and trichinosis. Some of these disorders can be prevented by vaccinations, such as Japanese B encephalitis and rabies, some by the use of insect repellents and some by avoiding raw milk products and undercooked meat. (2) Non-infective neurological disorders, such as acute mountain sickness and high altitude cerebral oedema, problems occurring during air travel such as syncope, seizures, strokes, nerve compression, barotrauma and vertigo, motion sickness and foodborne neurotoxic disorders such as ciguatera, shellfish poisoning and intoxication by cassava. This group of diseases and disorders could be prevented if the traveller knows about them, applies simple physiological rules, takes some specific medications and knows how to avoid intoxications in certain geographical areas. Meningococcal meningitis, malaria and jet lag syndrome are extensively discussed in other articles of this issue. The discussion in this paper will be limited to the other disorders.
