How would a computer function without a CPU (Central Processing Unit)? The brain is arguably the most important organ in the entire body, being the master coordinator of many vital body systems. The rest of the nervous system is an extension of the brain that takes in information from the environment and coordinates organ functions. When the nervous system becomes diseased, the brain tends to be affected as well as other organ systems throughout the body.

The following overview describes the most common neurological diseases, including what they are, symptoms, specific risk factors, and current treatment options.


Neurological diseases affect people of all ages. Many types are often thought of as being synonymous with aging; however, while a potential risk factor, aging is not a true cause of neurological disease.

According to a WHO report (2006), approximately 55% of the most common non-transmissible neurological diseases are cerebrovascular, 12% are a form of dementia and close to 8% comprise of epilepsy and migraine disorders respectively[1]. The rest have a relatively low incidence rate, which have seen an increase in years following the report.

Common types of neurological conditions include types of dementia, cerebrovascular diseases, conditions pertaining to malnourishment, and those caused by neuro-infections. There are also some secondary neurological conditions that are often symptoms of other diseases, but may present as chronic stand-alone health conditions too.

In this series, we discuss a range of neurological diseases. This includes dementia, cerebrovascular diseases and demyelinating diseases, infectious diseases that affect the nervous system, as well as tumors, secondary neuro syndromes and malnutrition diseases.
