Neurological disorder

A neurological disorder is any disorder of the nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. 

Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness.  Many neurological conditions cannot be cured.  Some can be prevented

Conditions such as stroke, dementia and migraine are the biggest global cause of ill-health. 3.4 billion people suffered a nervous system condition in 2021. The number of disability-adjusted life years due to neurological problems from 375 million in 1990 to 443 million in 2021. That is because the population has increased and people are living longer. The problems are much worse in poorer countries.
