Dual diagnosis is a common phenomenon affecting the modern day societies of the world. What is really responsible for the syndrome? There are a few reasons why many societies are witnessing the problem. But what is the meaning of dual diagnosis? How do we deal with the challenges associated with dual diagnosis? To start with, Dual diagnosis can be referred to as that condition that brings about the simultaneous existence and mental illness at the same time, a problem which assumes a dual nature. This condition appears to look like something that can further lead to more heterogeneous problem. However, the issue has led to many debates whether it is possible for someone to suffer similar faith of dual problems and yet still be referred to as a single problem. Experience has however shown that it is very possible for an individual to suffer problems that assume a dual nature other than a single problem. In the distant example we have problems associated with dual diagnosis to be seen to manifest in critical conditions like alcoholism and depression. This is a very good example of a problem that has to do with dual diagnosis. The condition can also be seen in a more serious mental illness like schizophrenia and psychosis. It can also manifest in conditions that has to do with substance misuse when it leads to development of certain disorders too, for instance, when an individual over use cannabis. Other forms of disorders that can lead to dual diagnosis problems are panic disorders, generalized anxiety disorders, and over dependence on drugs. It is however to be noted that substance abuse can on its own lead to a problems which can be regarded as self induced and it exist separately from a pre-existing mental illness or psychiatric. Persons with dual diagnosis problems always face complexities of problems such as a high rate of relapse, frequent hospitalization is a common phenomenon for some parts of the world, it can further lead to homelessness and can even further worsen to non-conforming societal behavior which is abhorred in contacting dreadful diseases such as HIV AIDS, Hepatitis and other sexually transmittable diseases. The causes of co-occurring disorders are yet to be fully determined, but there are several propositions and theories that have been put forward by experts in the field of diagnosis.
