But if the malformation is severe, type I may cause symptoms such as: Pain in the lower back of the head into the neck; it usually develops quickly and intensifies with any activity that increases pressure in the brain, such as coughing and sneezing. [webmd.com]
The pain is many times worsened, or may be started by, sneezing, coughing, or straining. These activities are referred to as, 'valsalva maneuvers.' [disabled-world.com]
- Inspiratory Stridor

Ears
- Tinnitus
Helpful Definitions Tinnitus = "ringing in the ears" Nystagmus = irregular eye movements Dysphagia = difficulty swallowing Syncope = fainting Atrophy = "wasting away" (usually of muscles) Analgesia = inability to feel pain Dysesthesia = burning sensation [web.archive.org]
Since the age of 35, the patient had experienced headaches, oculomotor symptoms like blurred vision and diplopia, tinnitus and vertigo. [f1000research.com]

Urogenital
- Incontinence
Adults may also have nausea that is not exacerbated by head movements; incontinence (urinary first, fecal later if condition remains untreated) indicates significant destruction of the frontal lobes and advanced disease. [emedicine.medscape.com]
The degree of deficit depends on the location of the defect. (1) Low sacrum: bowel and bladder incontinence, perineal anesthesia. (2) Mid-lumbar/High lumbo-thoracic: lower extremity flaccid paralysis and deformities (clubfeet, hip subluxation), absence [hawaii.edu]
Neurologic
- Headache
[…] of chronic daily headache (CDH). [doi.org]
Coughing, laughing, bending forward, sneezing or looking up can worsen the headache. Headache may be confused with migraine. Neck Pain – often pressure like and radiating down the spine and across the shoulders. [web.archive.org]
Accordingly, headache and neck pain in Chiari I are often exacerbated by cough and Valsalva maneuver. Hydrocephalus occurs less frequently. [emedicine.medscape.com]
One of the more common reasons for a patient to see a chiropractor is for treatment of headaches. [dynamicchiropractic.com]
Painkillers can help relieve any headaches and neck pain. If your headaches are severe or you have problems caused by the pressure on your spinal cord (such as movement difficulties), surgery may be recommended. [nhs.uk]

Mission The mission of The Wisconsin Chiari Center is to advance the diagnosis, understanding of and treatment of the Chiari 1 malformation and related disorders in the hope of eliminating delay in diagnosis and treatment in the future. [wichiaricenter.org]
Frankly symptomatic patients should be offered surgical treatment. [emedicine.medscape.com]
The objective of any treatment is to stop the progression of symptoms and hopefully to relieve the symptoms. [neurosurgerydallas.com]
Prognosis
The prognosis otherwise depends on severity of the malformation, associated neurological abnormalities and complications. There has been some improvement in prognosis with improved diagnostic and surgical techniques. [patient.info]
Prognosis and Outcomes The key to good prognosis of Chiari II malformation is early recognition of symptoms and early treatment. Patients with less severe symptoms at diagnosis are much more likely to improve with surgical intervention. [csfinfo.org]
Diagnosis - Arnold-Chiari malformation- type 2 Prognosis - Arnold-Chiari malformation- type 2 Not supplied. Treatment - Arnold-Chiari malformation- type 2 Resources - Arnold-Chiari malformation- type 2 [checkorphan.org]
Prognosis Long-term prognosis for persons with Arnold-Chiari I malformations is excellent. Full recovery from surgery may take several months. [encyclopedia.com]
Etiology
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]
Without an obvious CM-I, other etiologies of a spinal syrinx must be conclusively ruled out. Only then can one reasonably expect to ameliorate the clinical course of these patients via posterior fossa decompression. [doi.org]
Although studies of etiology are few, an increasing number of specific genetic syndromes are found to be associated with Chiari malformations. Management primarily targets supportive care and neurosurgical intervention when necessary. [medlink.com]
Contraindications Surgical decompression of foramen magnum is contraindicated when tonsillar herniation is caused by etiologies other than Chiari malformation, such as mass lesions in the posterior fossa or CSF hypotension syndrome. [emedicine.medscape.com]
Epidemiology
Pascual J, Colás R, Castillo J: Epidemiology of chronic daily headache. Curr Pain Headache Rep 2001, 5 :529–536. PubMed Google Scholar 5. [doi.org]
Epidemiology Chiari type I Retrospective investigation of brain MRIs has found a prevalence of 1 in 1,280 individuals [ 5 ]. It tends to present earlier if there is syringomyelia. [patient.info]
Epidemiology It used to be said that Chiari malformations are rare, but with routine use of MR imaging Chiari malformation is discovered with increasing frequency. [physio-pedia.com]
Epidemiology The most common Chiari malformation is type I and has been estimated to occur in 1 in 1000 births. The majority of these cases are asymptomatic. [emedicine.medscape.com]
Pathophysiology
While the final outcome of CM-I may be the same, the strength of the correlation and pathophysiological mechanisms of each differs greatly and some may be spurious associations. [doi.org]
Renewed effort to address current deficits in Chiari research involves work groups targeted at pathophysiology, symptoms and diagnosis, engineering and imaging analysis, treatment, pediatric issues, and related conditions. [medlink.com]
