Overview
Syncope should be differentiated from other conditions causing partial or complete loss of consciousness. These disorders may include, coma, dizziness, seizure, and vertigo. There are conditions that may mistakenly be diagnosed as syncope. These conditions include epilepsy, hypoglycemia, intoxication, cataplexy, and transient ischemic attacks.
Differentiating Syncope from other Diseases
Syncope should be differentiated from other conditions causing partial or loss of consciousness. These disorders may include:[1]
A quick algorithm to differentiate syncope from other causes of altered mental status is demonstrated below:
| Syncope | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Loss of conscoiusness | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| No | Yes | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| • Transient? • Rapid onset? • Short duration? • Spontaneous recovery? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Falls | Altered consciousnes | Yes | No | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Coma | Aborted SCD | Others | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| T-LOC | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Traumatic | Non-traumatic | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Syncope | Epileptic seizure | Psychogenic | Rare causes | ||||||||||||||||||||||||||||||||||||||||||||||||||||||
Abbreviations: SCD: Sudden cardiac death;LOC: Loss of consciousness.
| The above table adopted from ESC guideline [2] |

| Conditions Incorrectly Diagnosed as Syncope |

| Disorders with partial or complete loss of consciousness |
|
|
| Conditions without loss of consciousness |

| The above table adopted from ESC guideline [2] |

Syncope, must be differentiated from other diseases that may cause, altered mental status, motor and or somatosensory deficits. The table below, summarizes the neurologic differential diagnosis for syncope:
| Diseases | History | Symptoms | Physical Examination | Diagnostic tests | Other Findings | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Headache | ↓ LOC | Motor weakness | Abnormal sensory | Motor Deficit | Sensory deficit | Speech difficulty | Gait abnormality | Cranial nerves | CT/MRI | CSF | Gold standard test | |||
