While there are many similarities among people affected by depressive condition, there are some noteworthy differences between women and men when it comes to depression.  Female specific depression conditions include pregnancy and infertility, premenstrual problems, postpartum depression, and menopause.

To complicate matters, women often experience what is called atypical depression.  This means that instead of eating less, women eat more, and instead sleeping less, women sleep more.


Men are typically less willing to seek help for depression or admitting to being depressed.  This is mainly due to when a man seeks help for depression, it can be seen as a weakness.  When looking for indications or symptoms of depression in men, it is important to know that not all signs and symptoms are the same as common depression symptoms.  For example, instead of feeling sad for an extended period of time, men often get angry and irritable for an extended duration.  Instead of using friends and food for support, men often turn to TV, alcohol, and sports to self medicate.


When women and men move into their golden years, there are many changes seniors experience in which many people are not prepared for.  With these changes, it’s not uncommon for a senior to experience a major depressive episode.  Common changes among seniors that can lead to depression include medical problems, retirement, loss of loved ones and friends, and isolation.   Some of the common signs and systems of depression in seniors include; social withdrawal, sadness, fatigue, weight loss or loss of appetite, loss of self worth, sleep problems, and suicidal thoughts or attempts.


During the teenage years, there are a number of changes that teens must cope with and adapt to. These changes can include; puberty, social pressures, and trying to find out who they are and where they fit into society.   When looking into signs of depression in teens and adolescents, it’s important to know they also have a different set of signs and symptoms compared to adults.

While sadness is common among many adults who are depressed, teens are more likely to show anger, aggressiveness, and hostility.  Teens who are depressed sometimes deal with these pressures by using alcohol and drugs, running away, participating in reckless behavior, and sometimes violence.

What Causes Depression?

While there may one event that triggers a depressive episode,  there are usually a number of underlying factors that need to be addressed as well.  Depression is generally a combination of environmental, biological, genetic, and psychological factors.

Major depressive episodes can be caused by situational events such as a loss of a loved one, relationship problems, divorce, loss of a job, financial trouble, personal trauma, social pressures, and other instances that can affect a person’s overall well being.

While depression is usually genetic, it can also happen to those who have no family history of depression.

How to Treat Depression

After being diagnosed with depression, a combination of psychological sessions / treatments and medication is common when treating people for depression. Unlike other illnesses that can be treated with prescribed medication or surgery, changes in choices that led to the depressive episode and therapy are both instrumental in treatment and recovery.
