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). A rare cause is a cerebrospinal fluid leak.
[2] [3] Causes of a primary CSF leak are those of trauma including from an accident or intentional injury, or arising from a medical intervention known as iatrogenic. A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. [4] A lumbar puncture can give the symptom of a post-dural-puncture headache.
Glossopharyngeal neuralgia, a rare disorder, usually begins after age 40 and occurs more often in men. Often, its cause is unknown. However, glossopharyngeal neuralgia sometimes results from an abnormally positioned artery that compresses the glossopharyngeal nerve near where it exits the brain stem. Rarely, the cause is a tumor in the brain or ...
Occipital headaches; Orthostatic intolerance; Photophobia; Syncope; Tenderness at base of skull; Tinnitus; Tremors; Palpitations; Vertigo or dizziness; Weakness of limbs; Symptoms are frequently worsened by a Valsalva maneuver, or by being upright for long periods of time. The reason that being upright is problematic is that gravity allows ...
Problems with the greater occipital nerve may be a cause of cervicogenic headaches. [1] These may be referred to as occipital neuralgias. A common site, and usually misdiagnosed area of entrapment for the greater occipital nerve, is at the obliquus capitis inferior muscle. [2] These may be treated with a temporary nerve block. [1]
[1] [7] [8] [9] However, it is thought that the majority of NTS cases are due to genetics, in which loose ligaments cause temporary misalignments with the atlanto-axial joint while the neck is rotating. [3] Subsequently, numbness of the tongue is due to either subluxation of the atlanto-axial joint or restriction of the second cervical nerve. [2]
Triggers can include turning off lights, and going between dark to light or light to dark areas. [6] It is not uncommon to experience postictal headache, extremely similar to migraines after these seizures. Occipital epilepsy can cause many seizures per day and often in multiple clusters. The seizures may also spread to other areas in the brain.
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
