Answer:
Depression is not a fleeting emotion. It is a persistent disturbance of mood with complex roots in an individual's physiology and psychology, and it has marked symptoms. People with MS experience depression more than the general population or people with other chronic illnesses.
Step-by-step explanation:
Although psychiatric conditions are highly prevalent among individuals living with MS, many persons with MS do not exhibit clinically significant levels of depression, anxiety, or other serious mental illness.
When you're managing the symptoms of multiple sclerosis (MS), it's natural that you might find there are times you feel down. If you notice you're getting depressed, let your doctor know. He'll help you get the support and treatment you need to get back on track.
But MS itself might also cause depression. The disease may destroy the protective coating around nerves that helps the brain send signals that affect mood.
Depression is also a side effect of some the drugs that treat multiple sclerosis, such as steroids and interferon.
