Neurology and public health
Neurology is the branch of medicine that deals with the nervous system. Common neurological disorders include epilepsy, headache, Parkinson disease, and dementia, as well as neurological problems caused by other disorders, such as cerebrovascular disease and infections.
Hundreds of millions of people worldwide are affected by neurological disorders: more than 50 million people have epilepsy; around 47 million are affected by dementia globally.
Moreover, the extension of life expectancy and the ageing of the general populations in both developed and developing countries are likely to increase the prevalence of many chronic and progressive physical and mental conditions including neurological disorders.
