Mental Disorders

Despite the fact that it’s the 21st century, there is still significant stigma attached to mental illness.

The derogatory term "mentally ill" is often associated only with the most serious conditions, such as schizophrenia and bipolar disorder.

However, the Diagnostic and Statistical Manual of Mental Disorders (DSM) actually lists a wide range of psychiatric conditions, including everything from primary insomnia to nicotine dependence. Yet most people would never regard someone who’s been having trouble sleeping for the past month or a two-pack-a-day smoker as having a “mental disorder”.

Cause of Mental Disorders

Mental disorders are quite prevalent; they affect far more people than you might think. Granted, some disorders, like stress disorder, last for only a few days to a few weeks and then subside. Some mental disorders are recurring – which is often the case with disorders like major depressive disorder. But some, like schizophrenia, typically last a lifetime – even with treatment.

Despite all the advances of science, we still don’t know exactly what causes the vast majority of mental disorders In most cases it is believed to be a combination of factors including genetics, environmental influences such as childhood trauma, and imbalances in brain chemistry. Some believe that spiritual factors may also play a role.

Treating Mental Disorders

The traditional treatment of most mental disorders usually involves psychotropic medication, psychotherapy or a combination of both. Lifestyle changes – such as getting regular exercise, practicing meditation and/or yoga, using relaxation techniques, making dietary changes, or taking certain supplements – are also often beneficial, at least to some degree.

With regards to both our understanding and treatment of mental disorders, we’ve certainly made significant progress in the past century. It wasn’t really that long ago that individuals with serious mental illness were treated inhumanely – subject to horrific treatment such as witch hunts, imprisonment, exorcism, barbaric medical procedures and even human sacrifice.

We still have a long way to go and much to learn, however. Hopefully there will come a day when mental illness is not only truly understood, but advances in science will allow even those on the most severe end of the spectrum to live completely normal, happy lives with treatment – or better yet, to be cured from their illness entirely.
