WHAT IS DEPRESSION?
Depression is a real illness that impacts the brain. Anyone suffering from depression will tell you, it’s not imaginary or “all in your head.” Depression is more than just feeling “down.” It is a serious illness caused by changes in brain chemistry. Research tells us that other factors contribute to the onset of depression, including genetics, changes in hormone levels, certain medical conditions, stress, grief or difficult life circumstances. Any of these factors alone or in combination can precipitate changes in brain chemistry that lead to depression’s many symptoms.
Depression is a serious condition. It’s also, unfortunately, a common one. The World Health Organization characterizes depression as one of the most disabling disorders in the world, affecting roughly one in five women and one in ten men at some point in their lifetime. It is estimated that 21% of women and 12% of men in the U.S will experience an episode of depression at some point in their lifetime.
Depression does not discriminate. Men and women of every age, educational level, and social and economic background suffer from depression. There is no area of life that does not suffer when depression is present. Marriage, parenting, friendships, careers, finances – every aspect of daily living is compromised by this disease. Once an episode of depression occurs, it is also quite likely that it will recur. And the impact of depression can be even more severe when it occurs in combination with other medical illnesses such as diabetes, stroke, or cardiovascular disease, or with related disorders such as anxiety or substance abuse.
The problems caused by depression are made worse by the fact that most people suffering from the disease are never diagnosed, let alone treated. The good news is that when depression is promptly identified and treated, its symptoms are manageable and there are many effective strategies for living with the disease. Depression and bipolar disorder are both treated most effectively in their earliest stages when symptoms are less severe.
WHAT CAUSES DEPRESSION?
Although scientists agree that depression is a brain disorder, the debate continues about exact causes. Many factors may contribute to the onset of depression, including genetic characteristics, changes in hormone levels, certain medical illnesses, stress, grief, or substance abuse. Any of these factors alone or in combination can bring about the specific changes in brain chemistry that lead to the many symptoms of depression, bipolar disorder and related conditions.
WHAT ARE THE SYMPTOMS OF DEPRESSION?
Depression commonly affects your thoughts, your emotions, your behaviors and your overall physical health. Here are some of the most common symptoms that point to the presence of depression:
- Angry outbursts
- Loss of interest in friends, family and favorite activities, including sex
- Trouble concentrating
- Trouble making decisions
- Trouble remembering
- Thoughts of harming yourself
- Delusions and/or hallucinations can also occur in cases of severe depression
- Withdrawing from people
- Substance abuse
- Missing work, school or other commitments
- Attempts to harm yourself
- Tiredness or lack of energy
- Unexplained aches and pains
- Changes in appetite
- Weight loss
- Weight gain
- Changes in sleep – sleeping too little or too much
- Sexual problems
Of course, all of us can expect to experience one or more of these symptoms on occasion. An occurrence of any one of these symptoms on its own does not constitute depression. When healthcare professionals suspect depression, they commonly look for clusters of these symptoms occurring regularly for two weeks or longer, and impacting functional aspects of the person’s life.
