Depression and Suicide Prevention Toolkit
Major Depressive Disorder (MDD) is the most prevalent psychiatric disorder in the world. MDD is also known as clinical depression, unipolar depression or, simply, depression. The World Health Organization (WHO) predicts that by the year 2030 depression will be the leading cause of disability worldwide (World Federation for Mental Health, 2012). People with depressive illnesses carry out the majority of suicides. MDD is also the most common co-occurring disorder with other disorders, (Substance Use Disorder [SUD], for example) in precipitating suicide (Mood Disorders Society of Canada, 2013). Note: Bipolar Disorder (and Related Disorders) and Anxiety Disorders will not be examined in this Toolkit. The complexity and prevalence of these disorders cannot be sufficiently covered in the limited space available here.
