===== Diagnostic results =====
The following result of [investigation name] is confirmatory of [disease name]:
* Result 1
* Result 2
 
===== Sequence of Diagnostic Studies =====
The [name of investigation] should be performed when:
* The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
* A positive [test] is detected in the patient, to confirm the diagnosis.


=== Diagnostic Criteria ===
=== Diagnostic Criteria ===
* Here you should describe the details of the diagnostic criteria.
Many times, because there is no single test that can diagnose restless leg syndrome, the diagnosis of restless leg syndrome may be missed.
*Always mention the name of the criteria/definition you are about to list (e.g. modified Duke criteria for the diagnosis of endocarditis / 3rd universal definition of MI) and cite the primary source of where this criteria/definition is found.
* Restless leg syndrome is mainly diagnosed based on [[clinical]] presentation.  
*Although not necessary, it is recommended that you include the criteria in a table. Make sure you always cite the source of the content and whether the table has been adapted from another source.
*Be very clear as to the number of criteria (or threshold) that needs to be met out of the total number of criteria.
*Distinguish criteria based on their nature (e.g. clinical criteria / pathological criteria/ imaging criteria) before discussing them in details.
*To view an example (endocarditis diagnostic criteria), click [[Endocarditis diagnosis|here]]
*If relevant, add additional information that might help the reader distinguish various criteria or the evolution of criteria (e.g. original criteria vs. modified criteria).
*You may also add information about the sensitivity and specificity of the criteria, the pre-test probability, and other figures that may help the reader understand how valuable the criteria are clinically.
* [Disease name] is mainly diagnosed based on clinical presentation. There are no established criteria for the diagnosis of [disease name].
* There is no single diagnostic study of choice for [disease name], though [disease name] may be diagnosed based on [name of criteria] established by [...].


* The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
* Restless leg syndrome may be diagnosed at any time if one or more of the following criteria are met:  
* The diagnosis of [disease name] is based on the [criteria name] criteria, which includes [criterion 1], [criterion 2], and [criterion 3].
*# An urge to move the legs, accompanied with or caused by unpleasant [[sensations]] in the legs. Sometimes the urge is present without unpleasant [[sensations]], and sometimes these [[sensations]] are present in arms.
*# Urge to move the legs is present when resting or inactive.
*# Urge to move the legs is partially or totally relieved with movement.
*# Urge to move or unpleasant [[sensations]] are worse at night time as compared to day or only occur at night.


* [Disease name] may be diagnosed at any time if one or more of the following criteria are met:  
* Diagnosis of restless leg syndrome may be confirmed with:
** Criteria 1
** [[Family history]]
** Criteria 2
** Positive response to [[dopaminergic]] drugs.
** Criteria 3


IF there are clear, established diagnostic criteria:
* False positive diagnosis of RLS have been reported in more than 10% of the investigated populations and include conditions such as:
*The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
** Nocturnal cramps
*The diagnosis of [disease name] is based on the [criteria name] criteria, which include [criterion 1], [criterion 2], and [criterion 3].
** Various neuropathies
*The diagnosis of [disease name] is based on the [definition name] definition, which includes [criterion 1], [criterion 2], and [criterion 3].
IF there are no established diagnostic criteria:
*There are no established criteria for the diagnosis of [disease name].


* Reatless leg syndrome may be underdiagnosed because of poor recognition of symptoms.
* No guideline has been published describing how the criteria should be applied, and there is a lack of information about how essential and supportive criteria or associated features are related.

Overview

Diagnostic Study of Choice

Study of choice

  • Restless leg syndrome is mainly diagnosed based on clinical presentation.

Diagnostic Criteria

Many times, because there is no single test that can diagnose restless leg syndrome, the diagnosis of restless leg syndrome may be missed.

  • Restless leg syndrome is mainly diagnosed based on clinical presentation.
  • Restless leg syndrome may be diagnosed at any time if one or more of the following criteria are met:
    1. An urge to move the legs, accompanied with or caused by unpleasant sensations in the legs. Sometimes the urge is present without unpleasant sensations, and sometimes these sensations are present in arms.
    2. Urge to move the legs is present when resting or inactive.
    3. Urge to move the legs is partially or totally relieved with movement.
    4. Urge to move or unpleasant sensations are worse at night time as compared to day or only occur at night.
  • False positive diagnosis of RLS have been reported in more than 10% of the investigated populations and include conditions such as:
    • Nocturnal cramps
    • Various neuropathies
  • Reatless leg syndrome may be underdiagnosed because of poor recognition of symptoms.
  • No guideline has been published describing how the criteria should be applied, and there is a lack of information about how essential and supportive criteria or associated features are related.
