Causes of death in world.

Top 10 causes of death worldwide

Of the 56.4 million deaths worldwide in 2015, more than half (54%) were due to the top 10 causes. Ischaemic heart disease and stroke are the world’s biggest killers, accounting for a combined 15 million deaths in 2015. These diseases have remained the leading causes of death globally in the last 15 years.

Chronic obstructive pulmonary disease claimed 3.2 million lives in 2015, while lung cancer (along with trachea and bronchus cancers) caused 1.7 million deaths. Diabetes killed 1.6 million people in 2015, up from less than 1 million in 2000. Deaths due to dementias more than doubled between 2000 and 2015, making it the 7th leading cause of global deaths in 2015.

Lower respiratory infections remained the most deadly communicable disease, causing 3.2 million deaths worldwide in 2015. The death rate from diarrhoeal diseases almost halved between 2000 and 2015, but still caused 1.4 million deaths in 2015. Similarly, tuberculosis killed fewer people during the same period, but is still among the top 10 causes with a death toll of 1.4 million. HIV/AIDS is no longer among the world’s top 10 causes of death, having killed 1.1 million people in 2015 compared with 1.5 million in 2000.

Road injuries killed 1.3 million people in 2015, about three-quarters (76%) of whom were men and boys

Weather and stroke

Sudden drops in temperature can lead to a sharp increase in the risk of potentially-deadly brain clots.
Scientists have discovered that for every 2.9C (5.2F) decline in outside air temperature over a 24-hour period, the number of strokes in the general population goes up by 11 per cent.

Stroke problems- smell and taste

Our sense of taste and smell are very closely linked. Problems with either of them can have a real impact, especially on the way we eat and drink.

How can your taste and smell change after stroke?

A stroke can affect your taste in a number of different ways, so you may:

not be able to taste things as well as you did before, so flavours may not be as obvious or strong
get a salty, bad or metallic taste in your mouth
lose your sense of taste completely.

If a stroke affects your sense of smell you may:

not be able to smell things as well as you did before, so smells may not be as strong
become oversensitive to smell, so that smells become really strong
have a distorted sense of smell
lose your sense of smell completely.
Why does it happen?
Your taste and smell can change because of damage to your brain.

If the part of your brain that controls and receives information from your senses is affected by your stroke, then this can cause problems with your taste and/or smell.

Other problems can also add to these changes. Although it can be difficult to maintain good oral hygiene when you’ve had a stroke, if your teeth and mouth aren’t clean and healthy this can affect your sense of taste. A virus or infection can also have an effect on your sense of taste and smell.
