There isn’t any one thing that we can point to as the cause of depression. It’s a complicated issue really. Depression might be something brought about by a problem with a person’s genes. But at the same time, a person might get clinically depressed even if none of his family members or relatives have gotten depressed. Depression could also be something that arises because of experiences which are stressful or traumatic. But for some people, there’s no major event or turning point in their lives which signals the start of their depression.
While we may not know exactly what causes the changes in our brains which bring about depression, we at least know that there are certain factors that make depression more likely. So these are some things to watch out for. For instance, it’s been found that some types of medication may increase the likelihood of depression. This is why it’s important to talk with your doctor about the possible negative side effects of any medicines which are prescribed for you. Steroids, in particular, might help bring about depression. So at least, if you know that your medication might have this type of side effect, then you can prepare yourself mentally and in other ways for it.
