Doctors Diagnose OCD From A Manual Called The DSM

Its Editors Group Conditions By What They Resemble

Obsessive Compulsive Disorder Was Grouped With The Anxiety Disorders

That Grouping Lasted Until The Most Recent Revision

Editors Then Gave The Condition A Class Of Its Own

The Editors Pointed To Evidence For The Change

Researchers Have Not Finished Arguing About It

This Part Covers The Move And The Case Against It

OKAY BACK FROM THE ARCHIVE 🗂️

Every Diagnosis In The DSM Belongs To A Disorder Class

That Class Is Printed Beside The Diagnosis Itself

Under DSM Four The Disorder Class Was Anxiety Disorders

Before DSM Five It Was Categorised As An Anxiety Disorder

Placement Has Consequences Beyond The Order Of The Pages

It Determines Which Conditions Get Compared During Research

Funding Bodies Use Those Classes Too

Clinicians Learn That Comparison Early In Training

The Anxiety Grouping Had Real Support Behind It

OCD And Anxiety Commonly Co Occur

Each Responds To Evidence Based Pharmacologic Approaches

Psychosocial Intervention Approaches Work On Both As Well

Fear And Worry Symptoms Overlap Across The Two

Some Cognitive Features Appear On Both Sides

An Inflated Sense Of Responsibility Is One Of Them

Thought Action Fusion Is Another

Reassurance Seeking Completes The Set

None Of That Is A Weak Basis For Grouping Two Things

The Editors Still Decided To Separate Them

Their Reasons Are Printed In The Revision Itself

DSM Five Put The Condition In A New Disorder Class

That Class Is Obsessive Compulsive And Related Disorders

The Class Was Created To Reflect Increasing Evidence

That Evidence Concerns How These Disorders Relate To One Another

It Also Concerns Their Distinction From Other Anxiety Disorders

Helping Clinicians Identify And Treat People Was The Stated Aim

The Criteria Changed Alongside The Class

DSM Four Required Either Obsessions Or Compulsions

The Newer Wording Requires Obsessions Or Compulsions Or Both

Three Older Requirements Were Dropped From The List

One Stated That The Thoughts Are Not Simply Excessive Worries

Those Worries Concerned Real Life Problems

A Second Required Recognising The Thoughts As Ones Own Product

Recognising Them As Excessive Or Unreasonable Was The Third

Dropping That Third One Matters For People Who Lack It

DSM Four Offered A Single Insight Specifier Reading With Poor Insight

Three Of Them Appear In DSM Five Instead

With Good Or Fair Insight Is The First

Poor Insight Is The Second Of Them

Absent Insight Or Delusional Beliefs Closes The List

A Tic Related Specifier Was Added As Well

It Applies To A Current Or Past History Of A Tic Disorder

Reclassification Did Not Settle The Underlying Question

Some Preliminary Support Exists For A Distinct Neurobiology

Those Hedges Were The Researchers Own Words

Other Researchers Argue The Opposite Position

Their Case Is That OCD Should Be Retained With The Anxiety Disorders

Co Occurrence Throughout The Lifespan Is The First Reason

Shared Treatment Response Supports It Further

The Same Symptom Overlap Completes That Case

Evidence For The Split Comes From Somewhere Else

Some OCD Symptoms Have Salient Sensory Components

Those Symptoms Overlap Strongly With Tic Disorder

That Overlap Prompted The Tic Specifier In DSM Five

Two Reasonable Readings Come From The Same Evidence

The Editors Had To Pick One Of Them Anyway

Picking One Does Not Make The Other Disappear

Assigning A Class Is A Decision Rather Than A Fact

Decisions Get Revised When The Evidence Changes

This Condition Has Already Changed Classes Once

The Current Class Is Not Permanent Either
