Overview

Obsessive-compulsive disorder (OCD) may be classified into three categories based on co-morbiditiy into OCD simole complex, OCD co-morbid tic-related class, and OCD co-morbid affective-related class.

Classification

Subclassification Based on Co-morbidity

  1. An OCD simplex class, where major depressive disorder (MDD) is the most common additional disorder.
  2. An OCD co-morbid tic-related class, where tics are prominent and affective syndromes are considerably rarer.
  3. An OCD co-morbid affective-related class where panic disorder and affective syndromes are common.

Overview

There is no established system for the classification of [disease name].

OR

[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].

OR

[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].

OR

Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.

OR

If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].

OR

The staging of [malignancy name] is based on the [staging system].
