Brain Awareness Week 2016 Dementia Awareness Webinar – did you log in? The incidence of Dementia is increasing and is prominent in the news cycle. To address community concerns, Brain Foundation held an online presentation – “Dementia: How to Beat the Odds” to provide more medically authoritative information. As the population ages, dementia is increasing in the older cohorts. But Dementia need not be a normal part of ageing. It is a syndrome caused by a variety of brain illnesses that affect memory, behaviour and ability to perform everyday activities. Despite research so far, very few breakthroughs are happening because the funding is limited. Dementia will continue to affect many of the population. Our free online presentation was moderated by Professor Steve Robinson from RMIT School of Health and Biomedical Sciences and a director of Brain Foundation Victoria. Questions addressed were: • Why dementia is on the rise? • How to minimise your risks and implement preventative strategies;
There was also an interactive Q&A session at the end of the presentation. Offered to our supporters through email, social media and the National Headache Register, hundreds of people attended in what was an extremely informative and entertaining expert presentation. We have had many positive responses. Those who attended in took away valuable information.
More for us. Less for them. To help us give more to research and less to administration costs, Brain Foundation is implementing e-mailed receipts. If you would like your receipt e-mailed, please ensure we have your current details. You can fill out the section on the enclosed letter, make a donation on-line or e-mail us so we can update your information.

The information was very beneficial.” Due to the success of this Webinar, we will be holding another one in June on the topic of Dystonia. I’m sure most of our supporters may know a little about Dystonia but in order to learn more, then please log in. See our Dystonia section for the details. In the meantime, see Healthy Brain for some puzzles to stimulate those brain cells.

Valé John King It was with sadness that the Brain Foundation learned of the passing of John earlier this year. John, a former Senior Partner of PricewaterhouseCoopers, presided as the Foundation’s Treasurer for over 10 years and remained very close and
committed to the board and management of the Foundation. During John’s term, the Foundation grew significantly in size and John helped ensure that we were to remain strong well into the future. John recruited his successor, our current Treasurer, Bill Kuchta who is
also a former Senior Partner of PricewaterhouseCoopers. Tributes flowed from John’s many friends and these will go towards research into Parkinson’s in John’s name.

This will take place on June 7. People who suffer from a condition often learn a lot about it and potential treatment options. But, you never know what more you may learn. Many attendees from our Webinars on Dementia and the recent Migraine World Summit have expressed that they “learned more in a few days than they have in years”. So, sign up to attend! Ask family and interested friends to attend as well – it will help with their understanding of your everyday lives.
Great Wall of China: Great fundraising effort. In October this year, Nicole Botica will be taking on a personal challenge to walk a section of the Great Wall of China to raise funds and awareness of Dystonia. “My aim is to raise as much money as I can for Brain Foundation and specifically for the neurological condition Dystonia. My amazing family has felt, first hand, the heart breaking effects Dystonia has on people and their lives. So, in Loving Memory of John Aldrick from the extended family, I hope I can do great things for the people who battle this disease every day and for the fabulous researchers at the Brain Foundation.” This sounds like such an exciting challenge to do to raise awareness of Dystonia we all wish we were going too!

Headache Australia Migraine World Summit
As reported in the last Brainwaves newsletter, updated information on worldwide disability rated Migraines as the 6th highest cause of disability worldwide in terms of years lost to disability. A severe migraine can be as disabling as quadriplegia or active psychosis. Migraines are more common than diabetes, epilepsy and asthma combined. There are around 71,000 migraine attacks every day in Australia with around 3 million Australians affected. Yet, despite the prevalence of migraine, it remains under
diagnosed and under treated with less than 50% of patients consulting a doctor. And, for those who do, finding the right doctor can be difficult. Studies have shown only 4 hours are committed to headache disorders in undergraduate medical training worldwide. In April this year, Headache Australia took part in the first Migraine World Summit, a free online event where migraine patients had the opportunity to get access to the world’s top migraine experts. Over 30 doctors, professors and specialists gathered from world leading institutions, clinics, universities and hospitals – including Australia – to help answer some of the most difficult questions for patients in desperate need of relief. As
sufferers would know, there can be a significant wait to get good advice via a specialist. The Migraine World Summit provided unprecedented access to dozens of experts for those suffering from this debilitating disorder. It was a great opportunity to jump the queue and hear straight from the doctor about the latest best practices and approaches being used by leading physicians.

If you were not available to access the free talks in April, don’t worry. You can get access to 3 free talks from the Summit via migraineworldsummit.com or you can order all the talks from the Summit at headacheaustralia.org.au/ summit and 50% or your order will be donated to Headache Australia. Over $1600 has already been raised for Headache
“I thought I knew a LOT and I still learned a lot. So this was great.” Anny F
Below are a few comments from people who attended the Summit: “Thirty two years of migraine and I learned more in 5 days than I have in all those years with experts of my own. I am so glad I got the message to attend” Sharon N
“This is absolutely a.m.a.z.i.n.g! Thank you so much for putting this together. I have learned something from every talk I’ve listened to so far…those I thought would probably not be relevant were actually much more relevant than I could have imagined.” Helen P
Headache Awareness Week
– 12 to 16 September 2016
Headache Australia continues to offer Cefaly Devices to our Register members at a special rate.
In 2015 Headache Australia ran a series of face to face lectures about headache and migraine in the eastern states. The talks were given by prominent neurologists and proved to be extremely popular with our Register members who could attend. So, in 2016, we will be running another series of these talks in each state. Look out for the email advice with further information. The dates for these talks are as follows: Monday, September 12: Brisbane with Dr Nicole Limberg Perth with Dr John Cunningham Tuesday, September 13: Sydney with Dr Karl Ng Wednesday, September 14: Melbourne with Dr David Williams Thursday, September 15: Adelaide, Dr TBA
Cefaly is a TENS machine which works particularly well on headaches toward the front of the head. Latest data from Cefaly suppliers show that a significant reduction in headache and migraine is experienced by up to 75% of users. It is a drug free alternative and can also work well in conjunction with a reduced usage of your existing drugs. Give it a go!

Fabulous Fundraisers Callum paddles up a storm In January this year, Callum Smith paddled his way from Sorrento SLSC to Port Melbourne on a heavy Surf Lifesaving Board. Why do this some of you may ask?
Thanks to Chris Hartmann and her family for their stunning Christmas light display. The many visitors who came along to share the spirit were asked to donate to Brain Foundation for research into Aneurysms. The town has lost two members from the same family to this condition recently and so it was a cause close to many hearts.
He was raising funds for Brain Tumour research after his sister Jacinta suffered from a tumour in her brain stem. Successfully treated, Callum, a keen surf life saver, wanted to increase knowledge in the community and funds for research. As we had advertised this inspirational endeavour in previous newsletters, many of our donors supported Callum towards a very generous total. He also picked up donations on the overnight stops at Surf Clubs up the Bay and achieved his goal to increase awareness of this terrible condition.
Goondiwindi lights up the Christmas sky
Thank you to everyone from Goondiwindi who supported Chris and for your generous donations to this worthy cause. Brain Foundation Victoria President, Prof. Robert Medcalf (right) was there at the start and the ‘finish line’ and is pictured with Callum (left) and his family.
Abbey Dynasty gallops to a fine finish Brain Foundation sends a very sincere thank you to the organising committee and all the participants in the Abbey Dynasty Campdraft Carnival who travelled long distances to make this event such an outstanding success. The Campdrafting Carnival, held in September last year, was a memorial to the great horseman, Theo Hill, his mate Harry Ball and the champion Australian Stock Fiona with Coral Ball and the Brain Foundation ‘cheque’ at the Abbey Memorial, Willawarrin Horse, Abbey. Each of the 700 entrants on Showground. the weekend was descended from Abbey. Local farmers and owner drivers made the event possible by providing and transporting 2,000 head of cattle. In 1955, Abbey was born in the small NSW North Coast town of Willawarrin. In February this year Fiona from the Brain Foundation travelled back to Willawarrin where Abbey’s owner, Mrs Coral Ball, presented a cheque for research into Dementia. The Garvin Institute and Can Assist Narrabri were also recipients of donations from this very successful weekend.

A heartfelt thank you to Coriana Boothey, who organised a very successful trivia quiz night – the “Nutty Quiz Night”, earlier this year. Held in honour of her very dear friend and work colleague, Deborah Nuttall, the night raised significant funds to go to Aneurysm research.
Thank you both so much for your support at a time of great loss.
Football is certainly a popular sport and in March this year, this popularity was put to very good use.
Everyday Hero, Heroes
And a very special thank you to Erica Williams, who is running in the Brisbane City 2 South Running Festival in June. The loss of a loved one to a Brain Tumour has inspired this magnificent effort from Erica and her supporters. Best of luck on the day!
Everybody loves a good game of Football!
Early in 2016, the Foord family lost a son and brother, Braiden, to an Aneurysm. As is usually the way with Aneurysms, it was sudden and unexpected.

2016 Progress Reports A diagnostic profile of Vestibular Migraine using semicircular canal and otolith fundtion tests 2013 Brain Foundation Grant
Chief Investigator: Dr Sally Rosengren Vestibular migraine (VM) is a manifestation of migraine in which patients experience recurrent episodes of vertigo, which may coincide with a migraine headache, aura, phonophobia or photophobia (Lempert et al., 2012). Vertigo is a false sensation of movement of the self or surrounds and is a common and disabling symptom afflicting at least one million Australians each year. Vestibular migraine is the second most common cause of recurrent vertigo, but is often left undiagnosed and untreated due to the lack of clear diagnostic criteria and clinically applicable laboratory tests. Our project therefore aimed to improve the diagnosis of patients with vestibular migraine. Unlike other episodic vestibular disorders, the duration and quality of vertigo in VM is so diverse that it can mimic many other common vestibular disorders. Very short episodes lasting seconds to minutes can be difficult to distinguish from benign positioning vertigo (BPV), intermediate episodes lasting several hours are similar to Meniereâ&#x20AC;&#x2122;s Disease (MD) and long episodes lasting more than a day can be confused with vestibular neuritis (VN). We therefore aimed to investigate the diagnosis of VM by comparing it to the conditions it mimics, based on the duration of episodes. Preliminary results We planned to recruit 100 consecutive patients with definite or probable VM from the neuro-otology clinic of the Institute of Clinical Neurosciences at Royal Prince Alfred Hospital. Funding from the Brain Foundation of Australia has enabled us to recruit and collect data from 129 patients in total. Patients with clinically probable or definite migraine were recruited. Of the patients whose data has thus far been classified and analysed, 11 had probable or definite VM with short vertigo attacks (4 M, 7 F, aged 37-62 years) and 20 patients had intermediate duration attacks (6 M, 14 F, 15-68 years). We have not yet recruited patients with long duration attacks. In terms of patients with conditions mimicked by VM, we
have recruited and test 21 patients with definite MD (7 M, 14 F, 27-85 years) and are currently recruiting patients with BPV. Clinical characteristics of patients in these groups are shown in Tables 1 and 2. Table 1. Clinical Features (%) Sponta- Posineous tional vertigo vertigo
Table 2. Symptoms during vertigo attack (%) Headache
*HL was either worse during the attack or was reduced but no longer fluctuated Intermediate-duration episodes of VM versus MD Patients with VM with attacks lasting minutes to hours can be difficult to distinguish from those suffering from MD. While more than half of the VM group analysed so far describe having migraine at the time of vertigo (65%), a significant proportion do not, leading to a diagnosis of probable VM instead of VM. Patients with MD are less likely to describe headache as a feature of their episodes, though this does occur 26% of the time. Patients with MD report more aural symptoms, including fluctuating tinnitus and hearing loss, as expected due to the diagnostic criteria for MD. However, while the presence of tinnitus and hearing loss seem to be relatively good discriminators between the diseases, a feeling of fullness of the ear is less discriminative, as 40% of migraine sufferers also describe a sense of fullness. The other major difference is that MD patients mostly describe their vertigo as true spinning vertigo (84%),
while patients with VM are more likely to complain of rocking, tilting, or other manifestations of vertigo. In contrast to previous reports, both groups of patients with VM (short and intermediate duration) are only slightly more likely to report being sensitive to self-motion (55% and 60%) or visual motion (45% and 55%) compared to patients with MD (47% and 42%). The pilot data has shown higher rates of otolith abnormality in the patients with MD than VM (i.e. cVEMP and oVEMP asymmetry ratios). cVEMPs were abnormal in 40% of MD patients compared to 20% of VM patients, and oVEMPs were abnormal in 20% of MD patients and only 5% of VM patients. This is consistent with preliminary data collected by the Dr Welgampola, suggesting that VEMPs are robust in patients with VM (Taylor et al., 2012). oVEMPs were significantly smaller in affected vs unaffected MD ears (P<0.05), even after exclusion of frankly abnormal responses, suggesting the presence of subclinical damage to the otoliths. Semicircular canal function (i.e. the gain of the vHIT in each canal plane) fell in the normal range for all patients with VM, while 17/20 patients with MD had normal results. Two patients had canal paresis of all three canals in the affected ear, while another had reduced function of the right posterior canal on the affected side. Group analysis (excluding the 3 patients with frank abnormalities) additionally showed that the gain for the affected posterior canal was significantly lower (P = 0.002) in the MD patients (0.83) than the VM patients (0.94), suggesting that MD produced subclinical abnormalities that might become significant over time. Short- versus intermediate-duration episodes of VM There are already interesting differences emerging between the migraine patients who report having short (<5 mins) compared to intermediate length (mins-
hours) vertigo attacks. Patients with very short episodes are less likely to describe their vertigo as occurring spontaneously and more likely to complain of positional vertigo (64% vs 35%). The positional component of vertigo, along with the short duration of attacks, is the feature that most resembles BPV and causes difficulty in diagnosis. In the short episode group, the temporal link between migraine and vertigo is relatively weak (18%), while the patients report surprisingly high rates of tinnitus (36%) and fullness of the ear (64%) during attacks, features more usually associated with MD. Hypothesis vs Findings The proportions of patients with short (up to 5 min) and intermediate (5 min to 24 hours) vertiginous episodes in our sample are likely to ultimately match the rates expected based on previous reports (40% and 30%, respectively), but we have not yet recruited any patients with long duration (greater than 24 hours) episodes (Dieterich and Brandt, 1999; Lempert et al., 2012). This might be due to the fact that patients with long episodes are often initially diagnosed with vestibular neuritis, and only present for follow-up once a new episode occurs, which may be some time after the first attack. We have encountered higher rates of vestibular abnormality in the patients with MD than VM, as expected based on previous research on otolith reflexes (e.g. Taylor et al., 2012). However, the findings concerning semicircular canal function, as assessed by head impulse testing in all three canal planes for each ear, are novel. As expected, there are already differences emerging in the clinical characteristics and test results of patients with different durations of VM and between VM and one of its mimics, MD. However, as the number patients with definitive diagnosis and classification in our study is currently small, it is premature to conduct full regression analysis to determine the clinical and test factors that most discriminate between patients.

2013 Brain Foundation Grant Hypothesis vs Findings We hypothesised that genes frequently altered in human medulloblastoma contribute to the initiation and progression of this disease. Moreover, based on evidence from mouse models, we hypothesised that normal human neural stem cells are the cell of origin for this disease. Thus, we proposed that the introduction of genes/ mutations recurrently found in human medulloblastoma to normal human neural stem cells will recapitulate tumorigenesis upon intracranial implantation into mouse brains. Based on the findings of our collaborators at Johns Hopkins Hospital, our hypothesis was correct in the case of C-MYC overexpression in a Group 3 model of Figure 1: Research plan for the oncogenic transformation of human neural stem cells and subsequent generation of mouse models of medulloblastoma. medulloblastoma using human neural stem cells. We are currently in the process of determining if this is also the case using our genes of interest in the remaining three subtypes of medulloblastoma in our laboratory.

Tumour tissue will be subjected to routine histopathological analyses to examine the types of tumours formed and confirm the expression of each oncogene. Furthermore, DNA and RNA will be harvested from resulting tumours to enable molecular profiling to determine if the tumours match the molecular characteristics of the human disease.
