Exciting new developments are happening in Medicine every day but patients are flooded with information and cannot keep up with the latest evidence. A close family member of mine has been suffering from Crohn’s Disease for over 15 years.
Doctors are overburdened with patients and (understandably) cannot dedicate the appropriate time and attention to each individual case. I am the co-developer of MedNexus, a medical search engine for patients – think “Google for Medicine”. Through our search engine, you can find the most relevant content from a variety of sources: medical journals, government health sites, patient forums, etc.
Dr Todd Hardy, BSc (Hons), PhD, MBBS, FRACP, is a Consultant Neurologist at Concord Hospital, Sydney, Australia. The diagnosis of Susac’s syndrome has been facilitated greatly by appreciation of distinctive magnetic resonance imaging (MRI) findings. Susac’s syndrome is the triad of sensorineural deafness, branch retinal artery occlusions (BRAOs) and encephalopathy. In the majority of cases, Susac’s syndrome is a monophasic self-limiting disease that remits after one or two years.1 A polycyclic course has also been described in which patients have exacerbations of symptoms over several years.
A feature of Susac’s syndrome is visual field loss due to BRAOs (Figure 1).  Affected patients may be asymptomatic but equally others may be too encephalopathic to notice or report difficulties with vision. Figure 1: Fundus photograph (A) showing branch retinal artery occlusion (white arrow) with associated pale area due to focal retinal infarction (black arrow). In a recent cross-sectional observational study, nine patients with Susac’s syndrome with retinal involvement were assessed by optical coherence tomography and found to have a significant reduction in retinal nerve fibre layer thickness and macular volume compared to either healthy controls or patients with MS with or without a previous history of optic neuritis.6 The reduction in thickness was present in a sectorial distribution, particularly at the macula, as might be expected with retinal microvascular damage, and different to the generalised thinning seen in MS patients.
While hearing loss and tinnitus are common in Susac’s syndrome, vestibular symptoms such as vertigo and nausea are also frequent.7 Pure tone audiometry usually reveals bilateral sensorineural hearing loss which is asymmetric and is thought to reflect sequelae of microinfarction in the apical cochlea (Figure 2).
Susac’s syndrome is associated with pathognomonic MRI lesions in the central fibres of the corpus callosum referred to as ‘snowball’ lesions12 (Figure 3). Many patients with Susac’s syndrome are more disabled than their limited lesion load on imaging would indicate.
It is now widely held that Susac’s syndrome occurs as a result of an endotheliopathy of small vessels due to underlying autoimmune dysfunction.
Immunofluorescence studies have identified anti-endothelial cell antibodies (AECAs) in patients with Susac’s syndrome.2,15 Serum from eleven patients with Susac’s syndrome (among whom six of the patients had the full triad) was assessed by indirect immunofluorescence using generic cutaneous microvascular cells. It is not yet clear if AECAs have a pathogenic role in Susac’s syndrome or are merely an epiphenomenon. Susac’s syndrome is sufficiently rare that randomised controlled therapeutic trials have not been possible and treatment is based on the results of physician experience supported by individual reports and case series.
For patients in the ‘recurrent BRAO’ group, less aggressive therapy may be warranted as the clinical sequelae are usually less significant.4 In this group, treatment is the same as in the ‘encephalopathic form’ except that oral corticosteroid taper is more rapid and that cyclophosphamide can be withheld in favour of monthly IVIg alone for six months.
For patients that deteriorate, continue to relapse, or are intolerant of this regimen then treatment with monoclonal antibodies has been attempted with some success. Intratympanic injection of dexamethasone in the acute phase of hearing loss and tinnitus may provide transient benefit and may help justify more aggressive immunotherapy on the grounds of potential for reversibility. The aim of treatment of visual deficits is prevention of further damage with immunotherapy as, once established, retinal infarcts are permanent. Prognosis is to some extent determined by whether patients have an ‘encephalopathic form’ of Susac’s syndrome or a clinical picture more in keeping with a ‘recurrent BRAO’ subtype (see Clinical and Epidemiologic Considerations and Immunotherapy). This simple technique recently discovered by scientists at leading medical universities is the best way to permanently silence the noise blaring inside your ears. There are three current developments on tinnitus reduction in terms of risk and elimination that is worth the while of people suffering from the problem.
While no conclusion has been made on whether caffeine can cure tinnitus, people are encouraged to drink coffee as a preventive measure for the health malady.
Vagus nerve stimulation is a device that promises to eliminate the sounds brought about by tinnitus through brain re-training. Chronic tinnitus sufferers currently turn to state of the art hearing aids for tinnitus reduction.
Because chronic tinnitus is a result of signal changes sent from the ear to the auditory cortex neurons in the brain, the device intends to retrain those neurons to discard the annoying noise. This tinnitus reduction program starts with the chronic sufferer wearing headphones and listening to computer-generated sounds.
He first listens to tones that trigger the tinnitus, after which he listens to different frequencies close to the problematic tone. The device, meanwhile, stimulates the vagus nerve with small pulses that trigger the release of chemicals increasing the ability of the brain to reconfigure itself.
It is based on the theory that regular suppression may train the brain to switch off hyperactive auditory signals.


However, the reproduction of a suppressing sound, unique to each sufferer, outside a laboratory, remains the unanswered challenge to tinAway developers. Tinnitus Control is a homeopathic remedy for tinnitus, consisting of two products, an all natural spray and dietary supplemental capsules. It is made up of all natural ingredients, making it safe to use at home sans side effects and purchasable without a prescription. Serious tinnitus sufferers can experience relief via tinnitus reduction with regular use of Tinnitus Control. Not only does Tinnitus Control eliminate the annoying sounds, it is also able to provide overall improvement in the health condition of its regular user.
Together with the annoying sounds, tinnitus symptoms including lack of focus, feeling of emptiness and insomnia go away all together with regular use of Tinnitus Control. Tinnitus Control eliminates the tinnitus sounds from the roots rather than masking the sounds with music or other audio recordings, which what hearing aids do. Tinnitus Control offers a more effective and longer lasting solution to the problem compared to sleeping pills that offer temporary help to sufferers by dozing them off to sleep. Navigating the sea of information available online can be daunting at best, and dangerous at worst. Patients not only have the ability but a responsibility to do their own research and learn about their diagnosis and the available treatments.
Whether you are looking for the latest evidence, or to learn from fellow patients, you can find reliable and actionable answers at MedNexus. He trained in Neurology in Sydney and London and was formerly Locum Consultant Neurologist in the Department of Neuroinflammation at the National Hospital for Neurology and Neurosurgery, Queen Square. As a result there is now increased recognition of what was once thought to be a very rare disease. The ‘encephalo-pathy’ refers to a range of cerebral manifestations including cognitive impairment, psychiatric disturbance, headache, seizures and focal neurologic deficits. Rarer still, is the chronic continuous phase characterised by fluctuating symptoms without true periods of remission. If Susac’s syndrome is suspected it is important to perform fluorescein angiography as BRAOs may be diagnostic. Low-to-moderate range frequencies are preferentially affected and poor speech discrimination is common. Pure tone audiometry assessing (A) the right ear and (B) the left ear in a patient with Susac’s syndrome. It is conceivable, therefore, that fluctuations in circulating hormones may be relevant to the underlying mechanism of the disease, perhaps by inducing a hypercoaguable state, and may also be relevant to the overall female preponderance.
Sagittal T1 MRI sequences (A) and (B) showing corpus callosal ‘punched out’ holes (arrows). Newer studies using diffusion tensor imaging (DTI) have demonstrated evidence of widespread axonal damage not visible on conventional MRI which may account for this mismatch13.
Brain biopsy specimens in patients with Susac’s syndrome show areas of microinfarction due to thickening of arteriolar media and loss of capillary networks. Nine patients were positive for AECAs and eight patients had a characteristic 50-kDa protein detected by western blot that was not present in comparator samples from patients with other autoimmune diseases. AECAs are not specific to Susac’s syndrome but have been identified in other autoimmune diseases including scleroderma, systemic lupus erythematosis and Behcet’s disease.2 In support of an antibody-mediated aetiology for Susac’s syndrome, more than 50% of capillaries in brain biopsy specimens stain strongly for the complement protein C4d2. There is broad agreement that treatment with high dose corticosteroids should be first line therapy. There is increasing recognition that early, aggressive treatment of the ‘encephalopathic form’ of Susac’s syndrome is necessary. Patients with a first ever episode of BRAO should probably be treated aggressively from the outset as their disease subtype remains undeclared and the potential neurological sequelae of a relapse may be devastating meaning that the potential benefits arguably outweigh the risks of immunomodulatory therapy.
It may be that these agents will become the preferred therapeutic option as an adjunct to corticosteroids for early aggressive treatment of Susac’s syndrome as further data emerge. In those patients with profound sensorineural hearing loss consideration of cochlear implants is warranted7. Prior to the recognition of the need for aggressive treatment of the encephalopathic form of Susac’s syndrome, approximately 50% of patients suffered ongoing cognitive impairment.1 However, if treated early, many patients with Susac’s syndrome are now able to make an excellent recovery despite significant encephalopathy at presentation. Recent research developments have led to improved diagnosis and growing insights into its underlying immunopathogenesis. On the other end of the rope, ecaffeinated coffee had no effect on tinnitus risk whatsoever. As such, it is intended only for people whose lives are extremely affected by the tinnitus condition. His journey from doctor to doctor, hospital to hospital without any relief highlights the lack of consensus on courses of treatment and the heterogeneity of care.


The question is, how can someone without the benefit of a formal medical education make sense of and vet all the information they come across? The aim of this review is to provide an update on the latest developments in Susac’s syndrome and to highlight the importance of early and aggressive immunotherapy.
Because Susac’s syndrome is commonly misdiagnosed as various conditions including acute disseminated encephalomyelitis, multiple sclerosis (MS), neuro-Behcet’s disease, cerebral vasculitis, temporal arteritis or Cogan’s syndrome3 it may be more prevalent than originally supposed. Retinal arterial wall atheromatous plaques (Gass plaques) may also be present at mid-arteriolar segments away from retinal artery bifurcations.
Note, peripheral BRAOs can be missed with fundoscopy underscoring the need to perform a fluorescein angiogram if Susac’s syndrome is suspected.
Later, as callosal lesions become chronic they assume the appearance of ‘punched out’ holes best seen on T1 sequences (Figure 4). In particular, microstructural degeneration in the genu of the corpus callosum on DTI appears to be characteristic of Susac’s syndrome. Initial treatment with intravenous corticosteroids is recommended followed by slowly tapering oral corticosteroids and addition of a steroid sparing agent such as MMF.
Neovascularisation resulting from retinal ischaemia has been treated with laser photocoagulation with some success8.
Treatment with early aggressive immunotherapy is warranted in many cases and a role for monoclonal antibody therapy is emerging as an adjunct to more traditional immunosuppression.

After years of looking for a long-term solution to help manage recurring infections, he came upon an online article highlighting a simple day-to-day approach that immediately provided relief. We want to provide a viable alternative to WebMD and all the pseudo-science you can find online, and enable patients to engage in meaningful conversations with their doctor. He is Australian Co-ordinator of the International Collaborative Study of Susac’s syndrome. In addition to these findings, punctate subcortical and infratentorial lesions are usually present and these may coalesce (Figure 3). Immunomodulatory agents most commonly used include intravenous immunoglobulin (IVIg), plasma exchange, azathioprine, mycophenolate mofetil (MMF), methotrexate, cyclosporin A and cyclophosphamide.
Both IVIg and cyclophosphamide are also suggested on a monthly basis for at least six months.4,5 Maintenance immunomodulatory treatment may be necessary for at least two years from remission11. This was not a recommendation from his doctors but information he had uncovered through his own extensive online research. The commonest areas affected are the periventricular regions, centrum semiovale, cerebellum, brainstem and middle cerebellar peduncles.
Ideally, an agent, or combination of agents, which can improve disability due to acute lesions but is also able to exert a sustained disease modifying effect is desirable. Risk of developing drug-induced hearing loss is greater in those with impaired kidney health or inner ear disorders (Ligezinski 2002). Gray and white matter lesions often enhance (70%) with leptomeningeal enhancement less common4,12.
