News Round-Up: February 2010 2nd Edition

The draft changes for DSM-V have been published by the American Psychiatric Association Draft Development Team for DSM-V here. I might have overlooked something but it looks as though it is an overview of the changes being suggested for specific conditions that are being presented.

Dementia Reclassification?

Firstly I was interested in what amounts to a wholescale reclassification of the dementias and related conditions into major and minor neurocognitive disorders. There are some nice ideas contained within this move including the consideration that it is not only memory which needs to be affected. However I was unclear on reading the descriptions of whether it would include the subtypes as I could find no mention of this. However it would be unusual if the various subtypes of dementia for which there is an abundance of evidence were not included as subtypes within this framework as this could be considered a step backward. Additionally I couldn’t find any mention of the term Mild Cognitive Impairment (although there are some broad similarities with minor neurocognitive disorder) and the various subtypes for which there is an emerging evidence base and which is the focus of research in the hope that a better understanding could lead to prevention or amelioration of subsequent dementia.

Mental Disorders Due to a General Medical Condition

There were very few changes here. One suggestion was to use a catatonia specified elsewhere instead of catatonia secondary to a medical disorder.

Personality Disorders

There are some big changes in the Personality Disorders. These have been reduced from 10 to 5. One of the difficulties with the current Personality Disorder types is the diagnostic overlap. A person may fulfill the criteria for more than one type of personality disorder. There are a number of changes to the criteria which should improve reduce the number of comorbid personality disorder diagnoses. A simple likert-scale is used for quantifying personality and personality traits and the five types are Borderline Personality Disorder, Antisocial/Psychopathic Type, Avoidant Type, Obsessive-Compulsive Type and Schizotypal Type.

Substance-Related Disorders

There are a large number of new diagnostic labels being considered for inclusion and subsuming current labels. For instance alcohol dependence syndrome may be subsumed under alcohol-use disorder. Cannabis withdrawal is another diagnosis being introduced. The discussions around the terms ‘addiction’ and ‘dependence’ are discussed below.

Schizophrenia and Other Psychotic Disorders

There are big changes to the diagnosis of Schizophrenia with a proposal for removing subtypes including paranoid schizophrenia, disorganised and catatonic schizophrenia. Changes are being suggested in order to bring DSM-V into closer alignment with ICD-10. Proposed changes to the criteria for Schizoaffective Disorder are meant to increase reliability. ‘Psychosis Risk Syndrome‘ is being introduced (see further discussion below) and a Catatonia Specifier is being suggested. This is apparently because catatonia is ‘often not recognised’.

Mood Disorders

Mixed anxiety and depression disorder is being introduced with criteria that avoid ambiguity. This is currently included in the appendix of DSM-IV. There is a proposal to rename Dysthymic Disorder as chronic depressive disorder. There is a proposal to replace Bipolar Disorder Most Recent Episode Mixed with a mixed specifier. There are a number of changes in the criteria of Manic Episode particularly around energy levels.

Anxiety Disorders

The proposal is to include Obsessive-Compulsive Disorder under a new category of ‘Anxiety and Obsessive-Compulsive Spectrum Disorders’. The changes here are further discussed in the ‘PsychBrownBag’ Blog and the ‘OCD Center of Los Angeles’ Blog below.

Somatoform Disorders

There is a proposed amalgamation of four conditions into ‘Complex Somatic Symptom Disorder‘ but for further discussion see the ‘OCD Center of Los Angeles’ Blog below.

Factitious Disorders

The proposal is to reclassify Factitious Disorders under Somatic Symptom Disorders.

Dissociative Disorders

Theere is a proposal to subsume Dissociative Fugue under Disssociative Amnesia. Similarly there is a proposal to remove Dissociative Trance Disorder and integrate the criteria into the diagnosis of Dissociative Identity Disorder which has a number of other proposed changes.

Sexual and Gender Identity Disorders

There are a number of new diagnoses.

Eating Disorders

A new diagnosis of Binge-Eating Disorder is recommended (for further discussion see below). In Anorexia Nervosa there is the proposal to remove the criterion of amenorrhoea whilst in Bulimia Nervosa there are some proposed changes to the frequency of binge eating episodes and the purging criteria.

Sleep Disorders

There are a number of new conditiosns (a number of which subsume other conditions) including Klein-Levin Syndrome, Primary Central Sleep Apnoea, Primary Alveolar Hypoventilation, Rapid Eye Movement Behaviour Disorder and Restless Leg Syndrome amongst others. There are a number of changes to the criteria for narcolepsy including hypocretin deficiency.

Childhood disorders

There are a large number of suggested changes including the removal of Rett’s Disorder, a number of proposed changes to the Attention Deficit and Hyperactivity Disorder criteria, the inclusion of Post-Traumatic Stress Disorder in school age children and Temper Dysregulation Disorder with Dysphoria which is further discussed below. Interestingly the wording for Separation-Anxiety Disorder may be changed so that it can be used with adults also. This is because there is evidence for an adult separation-anxiety disorder.

Impulse Control Disorders Not Elsewhere Classified

There is a proposal to include Pathological Gambling with substance-related disorders. There are proposed changes for Trichotillomania further discussed below.

Adjustment Disorders

There is a proposal to move Adjustment Disorder to a grouping of Trauma and Stress-Related Conditions.

Discussion of the Draft DSM-V Changes Elsewhere in the Media

Links to some of the discussions elsewhere in the media are given below.

General

The Time article looks at a number of proposed changes for DSM-V which includes the criteria for making a diagnosis of depression,use of a continuum and the case for autistic spectrum disorders, the possible grouping of non-dependence inducing substances together with dependence inducing substances in the addiction and related disorders, reducing the number of personality disorder types and making some amendments to some of the sexual disorders. Over at PsychCentral, Dr Grohol looks at a number of features of the DSM-V draft. He is encouraging of the inclusion of Binge Eating Disorder, but is critical of the criteria used in minor neurocognitive disorder, behavioural addictions and also temper dysregulation disorder whcih has a narrow time period fo 6 to 10 years for diagnosis. Over at the ‘Psyche Brown Bag‘ blog, Joyce Anestis comments on the restructuring of the multiaxial system as well as the arrival of a number of new disorders including ‘hoarding disorder’, ‘olfactory reference syndrome’, ‘skin picking disorder’ and ‘psychosis risk syndrome’ amongst others and is also confused by the proposed changes to the personality disorders. The Times has a look at a number of the proposed changes including ‘sluggish cognitive tempo disorder’. Web MD has an article on the changes and features an interview with Dr First who is critical of the utility of the diagnosis of ‘Psychotic Risk Syndrome’.

Dr Dan Carlat has a discussion of the proposed criteria on his blog and seems fairly positive on these (however I would just add that there are neurobiological criteria for a number of disorders in DSM-IV/DSM-V draft e.g hypocretin deficiency in narcolepsy above). He notes that temper dysregulation disorder is being favoured as it would avoid a diagnosis of bipolar disorder in children in a number of cases. He’s in favour the use of addiction in place of dependence or abuse and also the use of the concept of binge-eating disorder. The New York Times has a piece featuring interviews with several psychiatrists and 230 comments at the time of writing. Integral Options cafe has links to a number of posts including those on the NPR site. An article at the NPR website examines the limits of the checklist approach and how severity might be measured when using a dimensional approach. The Economist has a piece on the history of the diagnostic criteria but also cover some of the disputes that have taken place. ‘DSM-V and ICD-11 watch’ have some interesting links as well as a brief look at suggestions for medically unexplained symptoms. Dr Finnerty has an overview of proposed changes as well as some useful links. Mind Hacks has coverage here and here. The APA have a facebook site that interested readers can join.

‘Addictions’

Stanton Peele covers the proposed use of the term addictions in this ‘The Huffington Post’ article.  The ‘Join Together‘ website features an interview with Dr Charles O’Brien who is chair of the APA’s DSM substances related disorders workgroup. He explains the distinction between dependence and addiction and the consideration of including the term addiction in DSM-V. They also discuss the possibility of collecting behavioural addictions together with alcohol and other drug related disorders.

Anxiety Disorders and OCD

Tom Corboy director of the ‘OCD Center of Los Angeles’ writes about a number of proposed changes over at the ‘OCD Center of Los Angeles’ blog. Thus Corboy discusses the suggested use of an ‘Anxiety and Obsessive Compulsive Disorder Spectrum’. Corboy is also critical of the suggestion of agaraphobia without panic disorder, in favour of moving Body Dysmorphic Disorder into the ‘Anxiety and Obsessive Compulsive Disorder Spectrum’ and adding a muscle dysmorphia variant, critical of the aggregation of 4 somatoform disorders including hypochondriasis, in favour of the relabelling of trichotillomania as ‘hair pulling disorder’ and also for the inclusion of skin picking disorder.

Intellectual Disability

Over at the blog ‘Mental Incompetence and the Death Penalty‘ there is a guest post by Dr Watson. He criticises the proposed criteria for intellectual disability on the basis that there doesnt appear to be a consideration of the standard error for IQ testing meaning that there is what he describes as a ‘bright light’ cut-off point of 70 or below whereas in practice there is a group that are scored over 70 who would still be included amongst a number of criticisms.

Bipolar Disorder in Children

Over at the NPR website, there is a wider discussion of the diagnosis of bipolar disorder in children as well as the more recent ‘temper dysregulation disorder’.

Autistic Spectrum Disorders

The Left-Brain Right-Brain blog compares the criteria in DSM-IV with those in DSM-V for autistic disorder and autistic spectrum disorders respectively and links to a number of other articles on the subject. There is another discussion of the autistic spectrum disorders proposition here. There is further coverage here and here.

Eating Disorders

Time has a piece on orthorexia which hasn’t made it into the draft version of DSM-V. There is also coverage of the proposed changes at the Ed-Bites blog (with 15 comments at the time of writing).

    Excellent morning. I wanted to write you a quick comment to express my thank you. I’ve been reading your blog page for a month or so and have picked up a huge amount of good data as properly as loved the way you have setup your website. I am attempting to run my own website but I feel it is considerably too general. I’d like to concentrate far more on narrower topics. Being all issues to all people isn’t all that its cracked as much as be. Several many thanks.
