depression1Major Depression is a prolonged, deep sensation of sadness or feeling "down", blue, hopeless, helpless or worthless.

The following are common symptoms associated with depression:

- Feelings of sadness, loneliness, hopelessness
- Loss of interest or pleasure in activities
- Changes in weight or appetite
- Changes in sleeping pattern
- Feelings of worthlessness or inappropriate guilt
- Difficulty concentrating, remembering things or making decisions
- Fatigue or loss of energy
- Restlessness or sluggishness
- Thoughts of death or suicide

About one in six Americans experience an episode of depression at some time during his/her adult life. (Approximately 1 in 6 of these will commit suicide in the course of his/her illness.)

Often, but not always, depression runs in families, and the course it takes is quite variable. Some people may only experience one significant depressive episode in their entire life, while others suffer with chronic depression which requires lifetime treatment.

Currently approved treatments may have side effects which some people cannot tolerate, may take 3 to 6 weeks to work, and may not work at all in one-third of patients treated.

Consequently, in collaboration with major pharmaceutical companies, Quantum Laboratories conducts monitored clinical testing on newer agents which offer the hope of minimizing these shortcomings.
