Overview
Syncope's differential diagnosis can be seen in the context of transient loss of consciousness. European Task Force created an algorithm to define whether or not there has been loss of consciousness, and from there, there could be a different possible diagnoses. [1]
Differentiating Syncope from other Diseases
Similar symptoms may be seen in other diseases such as:
There are some conditions incorrectly diagnosed as syncope, which can also be differential diagnosis. Those conditions can be divided on whether to not there was loss of consciousness. The conditions with loss of consciousness but without cerebral hypoperfusion are:[1]
| 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 | |||
