Depression can lead to permanent changes in the structure of the brain. In a study conducted at the University of Edinburgh, researchers found alterations in parts of the brain known as white matter – the key component of the brain and spinal cord consisting mainly of nerve fibres. White matter is critical for normal functioning of the brain, and its disruption has been linked to problems with emotion processing and thinking skills.
You have probably come across people using the word “depressed” to describe someone with mere sadness or the normal, everyday blues that last only a couple of days and get better on their own. But that’s just wrong. Depression is a serious mental health condition accompanied by feeling of extreme despondency that can result in reduction in person’s vitality, vigor or spirits.
