Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
Neck-tongue syndrome (NTS), which was first recorded in 1980, [1] is a rare disorder characterized by neck pain with or without tingling and numbness of the tongue on the same side as the neck pain. [2] Sharp lateral movement of the head triggers the pain, usually lasting from a few seconds to a few minutes. Headaches may occur with the onset ...
Lack of CSF pressure and volume can allow the brain to sag and descend through the foramen magnum (large opening) of the occipital bone, at the base of the skull. The lower portion of the brain is believed to stretch or impact one or more cranial nerve complexes, thereby causing a variety of sensory symptoms.
A basilar skull fracture is a break of a bone in the base of the skull. [1] Symptoms may include bruising behind the ears, bruising around the eyes, or blood behind the ear drum. [1] A cerebrospinal fluid (CSF) leak occurs in about 20% of cases and may result in fluid leaking from the nose or ear. [1] Meningitis occurs in about 14% of cases. [2]
Occipital horn syndrome (OHS), formerly considered a variant of Ehlers–Danlos syndrome, [1] is an X-linked recessive mitochondrial and connective tissue disorder. It is caused by a deficiency in the transport of the essential mineral copper , associated with mutations in the ATP7A gene.
The occipital bone overlies the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord. Like the other cranial bones, it is classed as a flat bone. Due to its many attachments and features, the occipital bone is ...
Seizures originate in the occipital lobe and account for 5 to 10 percent of all epileptic seizure types. Generally, this type of epilepsy can have an onset anywhere from 1–17 years old in children, but the patient prognosis is good. Since the event is located in the occipital lobe, symptoms may occur spontaneously and include visual stimuli.
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
