Depression is an extreme mood disorder that can cause immense amounts of sadness and loss of activity/ participation in life. Depression is very serious and can change an individual completely. When people are depressed they don’t know to do anything or socialize. It alters your behavior and you no longer see the good in most things. There obviously are a lot of causes of depression, but I came across a very interesting article that questions whether or not depression can be triggered by viruses.
On the Harvard Health Blog, there was a paragraph stated about a group of researchers looking into this hypothesis. They carefully dissected a Danish data base that contains every person born in the country by a registration number.The data base consists of information and records of peoples health related issues. In the blog post “Infection, Autoimmune Disease Linked to Depression” by Patrick Skerrett, he says the following: “Among Danes born between 1945 and 1995, almost 92,000 had a mood disorder. Of these, 36,000 had suffered a severe infection or developed an autoimmune disease (such as type 1 diabetes, celiac disease, lupus, and the like) at some point before being diagnosed with the mood disorder… The researchers estimated that in the Danish population, severe infection and autoimmune disease account for 12% of mood disorders.” (Infection, 1).
Infections and viruses, along with the medication provided to help cure the, can cause inflammation in many parts of the body. Cytokines in our body become active when we swell up or inflame. Studies show that cytokines change how brain cells communicate. Cells begin to attack nerves and healthy parts of the body instead of fighting off the unhealthy cells that make people sick. This can also show that a virus can cause depression.
