It's easy to dismiss dips in mood, sleep issues, or suppressed appetite. But these could be subtle symptoms of depression. People with mild depression are six times more likely to slip into major depression. So, if you notice these types of symptoms, or others like sadness and waning interests in activities lingering for a couple of weeks, see a mental health professional or your EAP. Major depression can have long-term effects on your body, even contributing to dementia and heart problems. A short assessment takes only a few minutes and it could help confirm or rule out the diagnosis.
