Could depression really be all in your head? New research reveals that brain inflammation may be to blame for your depressed feelings. Those who are depressed have 30 percent more markers of inflammation compared to those who do not. The study, which was performed by the University of Toronto’s Center for Addiction and Mental Health, used PET scans to measure immune cell activation and inflammatory responses. Those who were severely depressed were found to have the highest amount of inflammation. In the past, researchers had found that inflammation associated with other health conditions such as heart disease, diabetes, cancer, autoimmune disease and other chronic illnesses could trigger inflammation in the brain and depressed feelings.
This is the first link between inflammation in the brain without other illnesses and a depressed mood. While this new research shines a powerful light on what causes this perplexing, often disabling illness, we also know that it is a complex mental condition that involves biological changes such as hormones or variations in brain chemistry and environmental and genetic factors. Some people may have a single trigger, such as a job loss or death in the family, while others may experience a cycle, such as those who suffer from seasonal affective disorder.
Other factors in feeling blue can include diet, lack of sleep, too much sitting and cold weather or temperatures where you live. Smoking, excessive drinking and a poor diet can make it worse. Even social media can play a role in our mental and emotional wellbeing. If you are feeling depressed, you can take steps to feel better. Many people find relief in simple lifestyle changes. Try to spend some time outside in the sun every day, preferably while being physically active. Eat a nutrient-rich balanced diet, and kick the bad habits that may be holding you back.
Evaluate your sleeping habits to identify those things that could be keeping you from getting a good night’s sleep. Find a hobby, learn something new, get involved in your community and spend some time doing something you really love. Changing your lifestyle can help you feel better but may not be enough for all depressed people. You may benefit from anti-inflammatory supplements, such as vitamins A, B6, C, D, E and K. Talk to your doctor about prescription medications. Because about 25 percent of people experience no relief from the first medication they try, let your doctor know if your medication does not seem to be working within a reasonable amount of time.
