Neurally mediated syncope may also occur when an area in the neck known as the carotid sinus is pressed. The third type of syncope is due to a drop in blood pressure when changing position such as when standing up. This is often due to medications that a person is taking but may also be related to dehydration, significant bleeding or infection. There also seems to be a genetic component to syncope.A medical history, physical examination, and electrocardiogram (ECG) are the most effective ways to determine the underlying cause. The ECG is useful to detect an abnormal heart rhythm, poor blood flow to the heart muscle and other electrical issues, such as long QT syndrome and Brugada syndrome. Heart related causes also often have little history of a prodrome. Low blood pressure and a fast heart rate after the event may indicate blood loss or dehydration, while low blood oxygen levels may be seen following the event in those with pulmonary embolism. More specific tests such as implantable loop recorders, tilt table testing or carotid sinus massage may be useful in uncertain cases. Computed tomography (CT) is generally not required unless specific concerns are present. Other causes of similar symptoms that should be considered include seizure, stroke, concussion, low blood oxygen, low blood sugar, drug intoxication and some psychiatric disorders among others. Treatment depends on the underlying cause.
As a result, the cervical spine become misaligned and produces direct spinal cord irritation creating tighter muscles on one side of the body Neck braces can help temporarily. Surgery is required if needed. Non-surgical treatment, to realign spinal misalignment, is corrected by a chiropractor. Diagnosis
Once there is an onset of the symptoms in the patient, the patients are screened through cervical-spinal imaging techniques: X-ray, CT, MRI. [2] The scanning technique points out any cervical vertebrae defects and misalignments. (Image 1. and 2.) When cervicocranial syndrome is caused as a result of a genetic disease, then family history and genetic testing aid in making an accurate diagnosis of cervicocranial syndrome. Prevention/Treatment
The treatment options vary since there are numerous causes of cervicocranial syndrome. General treatments include:

Pressure release via realignment of the vertebrae
Pain medication: acetominophen, aspirin, or ibuprofen
Manipulation of neck by Chiropractor : For example, vertigo symptoms can be relieved
Neck braces to avoid movement of neck and provide stability
Physical therapy
Injection: Combination (anesthetic and cortisone) drug to help alleviate the pain
Surgery to restore function and form of the spine
Cervical spinal cord stimulation (cSCS) When cervicocranical syndrome is caused by a mutation in genes and it runs in the family due to other co-morbidities, genetic counseling helps patients cover risks, prevention and expectations of caring and passing genes to a newborn. Prognosis
The prognosis of an individual living with cervicocranial syndrome varies because of the multiple causes such as co-morbidities and varied trauma. Instability of the cervical spine can cause endangerment of patients and their neurological integrity.
