Opponents of Chiropractic have attempted a smear campaign over the last several years by suggesting that chiropractic adjustments to the neck increase the risk of a certain type of stroke.
With countless hours of research, studies and documentation supporting Chiropractic, it is time to put those false accusations to rest and educate the public on how and why Chiropractic does not increase the risks of these types of problems. Dissection of intracranial blood vessels is rare and has a worse prognosis than extracranial dissections. Patients with dissection of the arteries in the neck may present with any combination of craniocervical pain (in 50-80% of cases), cerebral ischaemia, cranial nerve palsy, Horner's syndrome, and pulsatile tinnitus.
Studies reveal the slight correlation between Chiropractic patients and stroke is likely due to patients experiencing headache and neck pain from VAD and seeking care before their stroke.

A 37-year old lady was referred from an optometrist with a two-week history of mild frontal headache and transient loss of vision. A 37-year-old recently married lady was referred by her optometrist with a two-week history of mild frontal headaches and transient visual obscurations. Humphrey visual field tests 24-2 showed bilateral enlargement of the physiological blind spots (Figure 2), and some mild scattered peripheral field defects. The patient was commenced on oral acetazolamide (Diamox) 250mg qid for 2 weeks, tapering down to 250mg daily over 3 months.
The optic nerve head swelling and blind spot enlargement were resolving by 5 weeks, and had completely resolved by 3 months (Figure 3). Idiopathic intracranial hypertension (IIH), presents with symptoms and signs of raised intracranial pressure.
Previously the condition had been called “benign intracranial hypertension” or “pseudotumour cerebri”.
Adult patients who present with papilloedema and symptoms of raised intracranial pressure need urgent multidisciplinary assessment including neuroimaging to exclude life-threatening causes. All patients with optic disc swelling should be suspected of having an intracranial mass until proven otherwise.
Idiopathic intracranial hypertension (IIH) is a diagnosis of exclusion: There is raised intracranial pressure in the absence of an intracranial mass lesion or hydrocephalus, with normal cerebrospinal fluid constituents (on lumbar puncture).
Visual loss such as blindspot enlargement in IIH may occur either early or late in the disease process and is usually insidious. Case Of The MonthEvery month Retina and Macula Specialists will publish an interesting case of a retinal condition. A patient presented with a right internal jugular venous hum causing audible tinnitus and a right sensorineural hearing loss, both of which resolved after high ligation of the right internal jugular vein. Unfortunately, because so little is known about the causes of tinnitus, little therapy is available to eliminate the problem.
This simple technique recently discovered by scientists at leading medical universities is the best way to permanently silence the noise blaring inside your ears. Dissection of the internal carotid and vertebral arteries in the neck accounts for about a fifth of strokes in the young compared with about 2.5% in older patients. Arterial dissection occurs when blood tracks into the vessel wall along a specific line of cleavage. Pain often precedes neurological features, usually by hours or days but occasionally by weeks.

Bilateral optic disc swelling with blurring of the disc margins and retinal nerve fibre layer haemorrhages. Magnetic resonance imaging (MRI) and venography (MRV) of the brain was normal, with no intracerebral abnormality or cerebral venous sinus thrombosis. She was also told about the importance of weight loss in the treatment of this condition, and saw a dietitian and her general practitioner to assist with this. Resolution of the optic disc swelling, 3 months after commencement of acetazolamide (Diamox). Restoration of normal visual fields, 3 months after commencement of acetazolamide (Diamox). Over a 10-week period OCT of the retinal nerve fibre layer showed a reduction in thickness from 125?m to 101?m (right eye) and 132?m to 97?m (left eye). Headache, nausea and vomiting are common, and additional complaints may include transient visual obscurations (secondary to papilledema), diplopia (secondary to sixth nerve palsy), visual field loss, pulsatile tinnitus, and dizziness. Our patient was very fortunate in that she responded well to Diamox and having her Implanon® implant removed.
A practical approach to, diagnosis, assessment and management of idiopathic intracranial hypertension. The role of weight loss and acetazolamide in the treatment of idiopathic intracranial hypertension. There are other causes of hearing loss in divers and, even if obvious acute causes, such as decompression sickness and inner ear barotrauma, can be excluded, repetitive subclinical episodes of these same conditions must be considered. This may be subintimal, causing luminal narrowing or occlusion, or subadventitial, when a pseudoaneurysm may form. The pain has been described as stabbing, pulsating, aching, "thunderclap," sharp, or "unusual." It is usually localised to the neck, head, eye, or face, with some tendency for the pain of carotid artery dissection to localise anteriorly and that of the vertebral artery to localise posteriorly. There were no other associated symptoms such as diplopia, vomiting, fevers, speech disturbance or limb weakness. Both eyes were quiet with severely swollen optic discs causing blurring of the disc margins (Figure 1). She had some mild paraesthesiae in her hands from the acetazolamide tablets, but otherwise had no other side effects. Over a 10-week period, OCT of the retinal nerve fibre layer showed a reduction in thickness from 125?m to 101?m (right eye) and 132?m to 97?m (left eye) (Figure 5). Most patients (>90%) with IIH have papilloedema (optic disc swelling secondary to raised intracranial pressure). Neuroimaging, best in the form of a MRI brain and orbits, and MRV (venogram), is done to exclude a space occupying lesion or cerebral venous sinus thrombosis.
Some patients are intolerant of the Diamox, or have progressive visual loss or severe headache despite maximal medical therapy. Follow-up of 57 patients from five to 41 years and a profile of 14 patients with severe visual loss.
That tinnitus which arises from and within the internal jugular vein is particularly important, as it may be loud enough to interfere with sleep, and result in some loss of hearing. If in fact contralateral problems are present, both muscles should be cut at the same time.
The sufferer might hear the pulsatile flow of the carotid artery or the continuous hum of normal venous outflow through the jugular vein when in a quiet setting.

Dissection of the major arteries in the neck is an important and probably underdiagnosed cause of stroke and craniocervical head pain.
Nerve fibre layer haemorrhages were present at both optic discs and spontaneous venous pulsations were absent.
Serum electrolytes were monitored, as sodium and potassium levels can be lowered by acetazolamide.
Hydrocephalus and cerebral haemorrhage are other important differential diagnosis to exclude. Dural venous sinus stenting and optic nerve sheath fenestration are potential surgical alternatives for such patients.
Objective tinnitus is uncommon and results from noise generated by structures near the ear.
Many operations have been described for the treatment of venous hum tinnitus and carotid arterial tinnitus; Although pulsatile tinnitus can be audible, objective demonstration of this. She had an Implanon® (etonogestrel, a steroidal progestin) contraceptive implant, but was on no other medications. A neurologist was consulted to perform a lumbar puncture, which showed an elevated intracranial pressure at 34cmH2O.
As is typical with acute papilledema, visual acuity is most often normal; visual fields may show an enlarged blind spot but usually no additional defects.
A lumbar puncture should also be performed by a neurologist, which usually shows a cerebrospinal fluid pressure greater than 20cm H20 and the fluid to be cytologically and chemically normal.4 When there is no apparent underlying cause found for the elevated intracranial pressure, IIH can be diagnosed.
Dehiscence of the jugular bulb is a normal venous variant, in which a superolateral extension of the jugular bulb extends into the middle ear cavity through a dehiscent sigmoid plate. Analysis of the cerebrospinal fluid showed normal protein and glucose and no white blood cells, red blood cells or organisms. In longstanding, untreated, or severe cases, optic nerve function may deteriorate, with the development of visual field defects.
However, tinnitus arising from and within the internal jugular vein has been reported only infrequently. Central Venous Pressure (CVP) : Use the right Internal Jugular to estimate CVP because it is straighter. In tinnitus, they may falsely relay information at a certain frequency that an externally audible sound is present, when it is not. Ototoxic drugs can cause tinnitus either secondary to hearing loss or without hearing loss, and may increase the damage done by exposure to loud noise, even at doses that are not in themselves ototoxic.
When tightening the muscles in my temple by blinking hard or by closing my eyes it causes a loud ring that fades the instant I stop squeezing the muscle.
Mind you, I have a constant ringing right now, quite loud, that intensifies when I do this.
For venous tinnitus, possibilities include jugular vein ligation, occlusion of the sigmoid sinus, or closure of a dural fistula.
