The constellation of symptoms caused by craniocervical instability is known as "cervico-medullary syndrome" [4] and includes: [5] [6] [7] Anxiety disorder; Bobble-head doll syndrome, a sensation that the skull may fall off the cervical spine; Clumsiness and motor delay; Cognitive and memory decline; Double or blurred vision; Dysphagia, or the ...
Cervical spinal nerve C7 controls triceps and wrist extension. Cervical spinal nerve C8 helps control the hand. [18] The cervicocranial syndrome occurs when symptoms arise due to cervical vertebrae damage (misalignment, collapse, shift or disease, such as tumor) resulting in the improper functioning of the cervical spinal nerves.
The lateral corticospinal tract is a descending motor pathway that begins in the cerebral cortex, decussates in the pyramids of the lower medulla [1] (also known as the medulla oblongata or the cervicomedullary junction, which is the most posterior division of the brain [2]) and proceeds down the contralateral side of the spinal cord.
[27] [28] [40] [41] Syringomyelia of cervical or cervicothoracic spinal cord can be seen. Sometimes the medullary kink and brainstem elongation can be seen. Can be congenital, or acquired through trauma. When congenital, may be asymptomatic during childhood, but often manifests with headaches and cerebellar symptoms.
Lesions in the brain stem or upper cervical spinal cord can cause respiratory insufficiency. Lesions in the area postrema of the medulla oblongata can cause vomiting or hiccups , as well as pain and tonic spasms .
Occipito-cervical junction This disorder may result from rheumatoid arthritis, causing the hypermobility of the connection between the neck and head, resulting in paralysis or pain. [ 6 ] Cerebrovascular disease Cerebrovascular disease is a type of cervical spine disorder that can cause tetraplegia .
Cervical spinal stenosis is one of the most common forms of spinal stenosis, along with lumbar spinal stenosis (which occurs at the level of the lower back instead of the neck). Thoracic spinal stenosis, at the level of the mid-back, is much less common. [2] Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.
Medial medullary syndrome, also known as inferior alternating syndrome, hypoglossal alternating hemiplegia, lower alternating hemiplegia, [1] or Dejerine syndrome, [2] is a type of alternating hemiplegia characterized by a set of clinical features resulting from occlusion of the anterior spinal artery.
