Depression is the most common of all psychiatric illnesses. It is estimated that at any one time worldwide, 300m—400m people suffer from depression. Depression cuts across all socioeconomic and racial barriers. Like most medical illnesses, we are learning that depression sometimes has a genetic component. Social and personal factors also play a role, but you often find that depression will run in families. Most depressions come with a certain amount of anxiety, which is why anti-depressants treat both depression and anxiety. Like most illnesses, depression can be seen as a spectrum, and those depressions can sometimes be treated with ECT in a hospital. Today, ECT is nothing like the ECT seen in One Flew Over the Cuckoo’s Nest. ECT is a safe and effective treatment for depression with minimal side effects.
