Globalisation, or the increased interconnectedness and interdependence of peoples and countries, is generally understood to include two inter-related elements: the opening of international borders to increasingly fast flows of goods, services, finance, people and ideas; and the changes in institutions and policies at national and international levels that facilitate or promote such flows. Globalisation has the potential for both positive and negative effects on development and health.

Non Communicable Diseases (NCDs)

Non communicable Is a medical condition or disease that is non-infectious or non-transmissible.

The social determinants of health are the conditions in which people are born, grow, live, work and age.

A stroke is caused by the interruption of the blood supply to the brain, usually because a blood vessel bursts or is blocked by a clot. This cuts off the supply of oxygen and nutrients, causing damage to the brain tissue.

The most common symptom of a stroke is sudden weakness or numbness of the face, arm or leg, most often on one side of the body. Other symptoms include: confusion, difficulty speaking or understanding speech; difficulty seeing with one or both eyes; difficulty walking, dizziness, loss of balance or coordination; severe headache with no known cause; fainting or unconsciousness.

The effects of a stroke depend on which part of the brain is injured and how severely it is affected. A very severe stroke can cause sudden death.

Urbanisation is where an increasing proportion of the population live in towns and cities. As a consequence of urbanisation, there is a reduction in the population living in rural areas.
