Can you smell that?

The sense of smell is very important. Did you know that this sense often gets affected due to depression? Many observe during pregnancy that their sense of smell heightens often making nausea worse so why is it that many suffer a loss of smell in the postanatal stage due to postnatal depression or other mental illness post baby?

"Personally, my husband did not believe me that my sense of smell had gotten so bad due to my postnatal depression and anxiety. Unfortunately now many smells go unnoticed or the degree of the smell needs to be greater in order to sense it..."

So here is why?

Depression, schizophrenia and seasonal affective disorder all suppress the sense of smell. The olfactory bulbs is the part of the brain that gives us our sense of smell. Researchers have found that the more severely depressed a person was, the smaller their olfactory bulb.  Therefore this suggests that depression may cloud, but not damage, a person's sense of smell. The reduced brain response to odours found in depressed persons may be tied to problems in two closely connected parts of the brain that play an important role in processing emotional information and smell, known as the orbitofrontal cortex and amygdala.

The effects were present whether or not an individual was taking antidepressant drugs.

It has also been noted that once the depression has been successfully treated the sense of smell/response to smells returned back to their normal levels.
