More than 300 million people worldwide suffer from depression, according to the World Health Organization. Twice as many women than men have depression, and all ages are affected.
Depression is especially important to recognize in pregnant or postpartum women, patients who are elderly or have cancer and in children and teenagers, as it can often be overlooked and can lead to devastating consequences.
At its worst, depression can lead to suicide, with more than 800,000 people dying of suicide every year. Notably, people who have gone through unemployment, loss of a loved one, a divorce or separation or even suffered a heart attack can become depressed. Depression also runs in families, so it’s important to know your family history of mental illness.
When patients with depression go to their doctors’ offices, two-thirds will present with symptoms such as a headache, backache or another type of pain, rather than admit they have depression. Often, it takes a direct question, such as “are you depressed?” for it to be recognized.
Common symptoms of depression
The following symptoms are typically present for at least two weeks, and depending on the number of symptoms, one can classify depression as mild, moderate or severe:
- Feelings of worthlessness, guilt or failure. People interpret minor setbacks in their life as personal failures.
- Becoming more withdrawn, or not caring to participate in activities that once caused joy.
- Depression causes loss of energy in routine activities. Sometimes people with depression report feeling exhausted before the day even begins. Losing that “get up and go” is commonly found in depression.
- Crying spells, or becoming teary-eyed are easily recognized signs of depression.
- Eating too much or binge eating, or conversely not having an appetite, can all be signs of depression. While there is no absolute number in weight gain or loss that defines depression, losing or gaining an average of 5 percent of one’s body weight per month is concerning.
- Sleep is often affected in depression, both in sleeping too much or not being able to fall asleep or stay asleep. This is frequently one of the earliest signs of depression. Depressed persons can feel fatigued despite getting a full night’s sleep.
- Depressed people often experience a loss of concentration or become easily distracted.
The more we understand and talk about depression, the earlier we can recognize it in our friends, families and loved ones. And for someone who’s suffering from this very real and debilitating disease, talking with a doctor can be the first step toward recovery.
Treatment for depression
Treatment depends on the severity of the symptoms. It can range from simple recognition of the disease to medications and, sometimes, admission to a hospital for intensive treatment. Many patients with depression benefit from counseling and behavioral therapy. Regardless, neither counseling nor medications work instantly. It can take up to two weeks to begin to see the beneficial effects of medicine and up to four weeks to see the beneficial effects of counseling.
People with depression have a lower quality of life and a higher risk of suicide than those without depression. Additionally, depressed patients affect the quality of life of those who live and work with them. Recognizing the symptoms of depression and identifying ways to manage and alleviate it can have a profoundly positive impact for the patient and his or her loved ones.
