It is common for people to speak of how "depressed" they are. However, the occasional sadness everyone feels due to life's disappointments is very different from the serious illness caused by a brain disorder. Depression profoundly impairs the ability to function in everyday situations by affecting moods, thoughts, behaviors, and physical well-being.
Depression strikes about 17 million American adults each year, more than cancer, AIDS, or coronary heart disease, according to the National Institute of Mental Health (NIMH). An estimated 15 percent of chronic depression cases end in suicide. Women are twice as likely as men to be affected.
Many people simply don't know what depression is. A lot of people still believe that depression is a character flaw or caused by bad parenting. Depression cannot be overcome by willpower, but, fortunately, depression is treatable. In the past 13 years, the Food and Drug Administration has approved several new antidepressants, including Wellbutrin (bupropion), Prozac (fluoxetine), Zoloft (sertraline), Paxil (paroxetine), Effexor (venlafaxine), Serzone (nefazodone), and Remeron (mirtazapine).
According to the American Psychiatric Association (APA), 80 to 90 percent of all cases can be treated effectively. However, two-thirds of the people suffering from depression don't get the help they need, according to NIMH. Many fail to identify their symptoms or attribute them to lack of sleep or a poor diet, the APA says, while others are just too fatigued or ashamed to seek help.
Left untreated, depression can result in years of needless pain for both the depressed person and his or her family. And depression costs the United States an estimated $43 billion a year, due in large part to absenteeism from work, lost productivity, and medical costs, according to the National Depressive and Manic Depressive Association.
