What people never understand is that depression isn’t about
the outside; it’s about the inside.
To say that depression is complex would be an understatement. Not only does it produce a variety of emotional, physical, and mental symptoms, but it can also be brought on by a host of different factors. Indeed, the intersection of chemical, lifestyle, and even genetic factors that contribute to this mental illness can make effective diagnosis and treatment challenging.
Yet, as one of the most common mental illnesses in the world, depression is a major public health issue that demands a comprehensive treatment approach. Not only is it associated with intense emotional pain, but it is also the number one cause of injury or illness for men and women across the globe and the leading cause of disability in the U.S. Moreover, people with depression face an increased risk of death from suicide and certain other illnesses including heart disease. 
At certain stages in life, most people experience feelings of:
These are normal and typically pass with time. Yet, for 322 million people worldwide, these feelings linger and manifest as a severe form of low mood, resulting in a diagnosis of depression as a psychiatric disorder. 
While many people with depression seek medication to treat their condition, only 6% use medication alone. For the majority of individuals living with depression, treatment through both medication and health professionals is pursued  – with the knowledge that, just as depression touches multiple areas of life, there are also many different strategies that can be used to alleviate its symptoms.
For adults in their middle ages and beyond, specific age-related factors can impact the way depression is brought on or managed. It therefore takes clinicians with a keen understanding of adult physiology to develop coping strategies that work for each individual, whether that’s alongside or independent of medications.
At Cenegenics, our age management specialists are acutely aware of not only the physical factors that influence the mental and physical wellbeing of adults, but also how conditions like depression can be significantly improved by optimizing health in key areas like:
In this guide, we’ll take a closer look at depression and how our specialists can help you meet its many challenges to improve your quality of life. Let’s start by discussing some of the symptoms of depression.
Depression is complex in the fact that it cannot be diagnosed simply based on a physical exam, lab tests, a psychiatric evaluation, or by using criteria listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).  It is commonly defined as feelings of sadness, emptiness, or hopelessness that persist for two weeks or longer and prevent someone from pursuing regular activities.  In addition, symptoms may include:
Oftentimes, people who have depression don’t experience every symptom. Its effects can also vary in intensity but are commonly experienced nearly every day.
Each person experiences depression differently and, in fact, there are multiple types of depression, some of which are brought on by distinct causes or circumstances.
The DSM-5 lists nine different types of depression, of which major depression is the most common. Major depression, often referred to simply as depression, may be experienced as recurring episodes over the course of an individual’s life. Some additional forms include:
Although conditions like postpartum depression and SAD are associated with specific circumstances, the culprit behind major depression isn’t always so easy to identify.
While sadness can be triggered by a multitude of circumstances, there are certain life events that can actually trigger depression. Illnesses, including chronic pain and cancer, as well as bereavement, social isolation, and stressful events including money troubles or divorce, can bring on the mental illness. Conversely, it’s also possible that a person to experience depression suddenly and without any discernible cause.
Although it’s not always precisely known what causes depression, experts suspect a variety of factors could be involved, as with most types of mental disorders, including:
In addition to direct causes, scientists suspect that there are several factors that could explain why certain individuals may be more likely to be diagnosed with depression. The following factors are thought to play a role in a person’s risk:
Depression is a very complex mood disorder that can affect multiple facets including a person’s emotional, physical and mental state. Depression can not only increase risk of death by suicide, it can also increase risk of certain chronic diseases including heart disease.
Depression can be triggered by multiple causes including:
