As limiting as vertigo is, it’s is considered a pretty harmless annoyance. In the worst case, it will cause broken bones after a bad fall. Right?
In fact, it may actually indicate you are suffering from a fatal disease that is not so obvious to spot.
Chronic depression is a very dangerous disease with a high fatality rate. Add hyperthyroidism to the mix and the results are even more devastating.
All the studies researching the connection have found that people with vertigo are more likely to suffer from depression than people without vertigo.
But does the connection go the other way around? Does depression potentially cause vertigo?
This is what a group of Taiwanese researchers decided to explore.
Almost all Taiwanese citizens use the National Health Insurance program for healthcare, so that was the perfect place to start.
From this database, they identified 10,297 people who were diagnosed with depressive disorders between the years of 2000 and 2009.
They drew the records of a further 41,188 people that did not have depressive orders with whom to compare the first group against.
After a few years, they noticed that people diagnosed with depressive disorders were 1.55 times more likely to develop vertigo than their psychologically healthy peers.
People with both depression and hyperthyroidism had a further increased risk of vertigo, which was 3.75 times more likely to occur than the healthy population.
Those with both depression and systemic lupus erythematosus together were 3.47 times more likely to develop vertigo than their healthy peers.
In other words, depression is a vertigo risk, and if it co-occurs with hyperthyroidism or systemic lupus erythematosus, the risk increases even more.
