    Transcript

    00:01 Now, why do we want to study and examine psychological disorders? Well, it’s kind of important because one, you need to identify and better understand what are the symptoms associated with each, and then next figure out sort of well, what is the prevalence or how common is this because as we’ll see today, there is a whole slew of different psychological disorders.

    00:22 It’s not so cut and dry.

    00:23 You have lots of overlap, you have a whole bunch of variety, and it is almost overwhelming to try and to asses somebody and try and establish what physical disorder they might have because you need a good understanding of the symptoms associated with each.

    00:40 And then you need to figure out well, how do I treat that once you’ve identified it, and then how common is this.

    00:47 So how do we do that and how is this all documented? Well, we have the bible, which is the DSM or the Diagnostic and Statistical Manual of Mental Disorders and it’s put up by the American Psychological Association.

    00:58 And they’ve had several renditions and this has been around for years, and the most recent one that’s out right now is the DSM 5 or the DSM V.

    01:06 And what it does is it actually tries to categorize and outline all the different types of psychological and mental disorders and it defines them.

    01:15 It’ll talk about the pathogenesis, it’ll talk about what are some of the characteristics that you see, treatment options, might even mention prevalence.

    01:22 And so it’s a way to say well, it’s in the DSM so this is, you know, A) legitimate and B) because it’s documented I’d have some better understanding of the variables and characteristics around it and it might also have some treatment options.

    01:35 So the DSM is adapted to align with current evidence and practice.

    01:39 And what we’re saying here is that they keeping out with newer versions as we begin to understand more.

    01:45 So that being said, the DSM really hasn’t changed a lot over the last few years.

    01:51 I think this, the gap between the most recent version of the DSM 5 and the IV was I believe almost 20 years, so I think 19 years.

    01:59 So in that 19 years it’s not like we’ve rewritten the book.

    02:03 We’ve simply added a few things, rejigged the organization because of our understanding, but the idea is we have one placed where somebody can go to and really try to figure out what it is that’s ailing you.

    02:17 We also have something else called the International Statistical Classification of Diseases and Related Health Problems called the ICD, a lot easier to say ICD than that whole name, and was put out by the World Health Organization.

    02:29 And so for that, the most common or recent version is the ICD 10.

    02:34 And again, what we do here is we have different codes and a map of all the different disorders and how they’re linked.

    02:40 And so as a psychologist or a physician, you can write down the ICD 10 code for, say for example, somebody is suffering from generalized anxiety disorder, that would have an ICD 10 code.

    02:51 You can see where it fits in the grand scheme of things.

    02:54 You could refer to the DSM 5 and look at some of the characteristics and symptoms to make sure they they align with your assessment of your patient who’s in front of you.
