Picture yourself waking up one morning with a severe, relentless itch that no clinician or diagnostic tool can understand. Your life would be thrown off kilter. Quality of life would suffer financially, psychologically, and socially as you try to look for a glimmer of light at the end of the tunnel. This is what life is like for most people living with a rare disease.
Often barraged with terms like ‘unknown’ or ‘undiagnosed’, matters can get even more challenging when the condition becomes more elusive or develops life-threatening consequences. And all of this is exacerbated by inequities in treatment and high costs of the few existing drugs that are available.
By EU standards, a rare disease is one that affects fewer than one in 2,000 individuals. And these ‘less common’ ailments are difficult to raise monies for to research, leaving large gaps in scientific and medical literature. One such disease is the poorly understood Idiopathic Hypogonadotropic Hypogonadism (IHH).
Characterised by the absence of puberty and infertility, IHH can be compounded by potentially severe characteristics such as congenital heart disease, osteoporosis at a young age, and early onset of Alzheimer’s disease.
Its cause is usually a genetic anomaly, but a single genetic change can affect two people very differently. This gives rise to an unparalleled complexity that makes the cause harder to decipher. Symptoms are not clear-cut and sometimes mask the actual underlying cause, bringing about misdiagnosis and delayed treatment. Timely diagnosis is crucial for successful treatment that enables the patient to achieve puberty and induce fertility. But this is not always possible.
Under the guidance of Dr Rosienne Farrugia, I am currently analysing and expanding upon a preliminary assessment of IHH in Malta using high-throughput sequencing (HTS) technology (conducted by Adrian Pleven). With HTS, we can read a person’s entire DNA sequence and attempt to identify differences in the DNA code which lead to such diseases.
What the team has found is that some genetic variants typical of IHH are more common in the Maltese population when compared to mainland Europe and African populations. This is likely due to the reduced genetic variation of our population, shaped by successive events of population reduction and expansion throughout our history.
By mapping the genetic cause of diseases prevalent on our islands, we can help medical consultants to employ specific screening tests that are tailored for local patients suffering from IHH. Such advancements in genomic technology and personalised medicine can make a huge impact on people’s lives. And not only to those suffering from IHH; researching one disease, however rare it may be, can shed light on mechanisms that prove useful in treating many others, ensuring that when it comes to health, no one is left behind.
This research project is being carried out as part of a Ph.D. program in Applied Biomedical Sciences at the Faculty of Health Sciences.
How does the loss of memory change a person? Can media replace memory? Giulia Bugeja asks several researchers to find out the affect on cultural memory and she also touches on dementia
When Mike* went to the nursing home that evening to visit his grandmother Maria*, she was worried that he wouldn’t be able to find her because the caretakers had changed her room. Mike tried explaining to her that her room on the 4th floor had been refurbished a year ago, but she couldn’t remember.
Dr James Corby
‘Can life without memory be considered a meaningful existence?’ asks Dr Charles Scerri (Malta Dementia Society, and Department of Pathology, University of Malta). Dr Scerri researches dementia. He is currently examining which physical environments and what sort of psychosocial wellbeing can improve life in local dementia hospital wards. In fact, Dr Scerri reports that today there are over 44 million people suffering from some form of dementia. That is around 100 times the Maltese population. He asks, ‘what type of society can we end up with if we are wholly made up of individuals with no past and an uncertain future?’
With more people relying on new media technology to record information and experiences, Dr Scerri’s question faces a future society where media could replace memory. ‘It would be short-sighted to think that new media will have no long-term influence on the complex nexus of personal and cultural memory’, says Dr James Corby (Department of English, UoM).
Photography already acts as a surrogate for memory. But, it does not stop there; theorist Roland Barthes goes one step further saying how photography can capture details missed by the human eye. As developers of new media strive to enhance experiences, more users are adopting them. In the final quarter of 2012 alone, Apple sold 37.4 million iPhones. This smartphone, equipped with HD video, an in-built camera, calendar, and interactive 3D map helps people capture memories and avoid having to remember appointments or directions. It even comes with Siri, your own ‘personal assistant’, to use Apple’s words.
Despite these abilities, Dr Corby is sceptical. As a researcher working on the interfaces between literature, philosophy and culture, Dr Corby thinks that the rich tradition of the humanities should inform debates about cultural memory. ‘The idea that a facility to record memories leads to the diminishment of personal memory is by no means a new idea. Indeed, it is precisely the accusation that, in Plato’s Phaedrus, Socrates makes against writing.’ Writing did not steal our ability to remember and neither should new technologies.
“You can never really know if what she’s saying is true because her memories are not always real”
So what would happen if old or new media failed us? When the accounts office of the family business burned down, Mike could relate to his grandmother’s anxiety due to her lack of personal memory. All the accounting records, invoices, transaction records, and overseas payments were destroyed. The accountant was so shocked that he still will not enter his old office after 15 years.
The accountant had to keep paper records. There was too much information to remember and they couldn’t memorise it all. Although they recorded the information they still lost it in the fire.
More about Alzheimer’s in Malta
Dr Scerri has collaborated with the Department of Pathology to launch the Alzheimer’s Disease Research Group (University of Malta). Their objective is to gather several multidisciplinary professionals to ‘promote and facilitate research and scientific collaboration in Alzheimer’s disease and other forms of dementia’. Together with Trevor Zahra, he recently released the publication X’ħin hu? Fatti dwar id-dimensja (What time is it? Facts about dementia).
We all risk losing both valuable information and the recollection of experiences. So what would happen if Malta became a nation of people without a memory of important events? For Dr Corby, a society which relies on new media and less on memory ‘might then lead to a complete eliding of any difference between personal memory and an increasingly undifferentiated surfeit of readily available cultural memory — a sort of technologised and globalised cultural eidetic memory’.
There’s also the possibility that media such as photographs could lead to the creation of cultural memories which never took place. ‘I imagine false memory to be the norm—it would be naïve to think that the visual representation of a culture […] is free from ideology’ says Dr Corby. Our national identity will instead be formed around uncertain events.
Joe Rosenthal’s photograph of American soldiers raising the American flag on Mount Suribachi on the island of Iwo Jima signifies a moment of national pride for Americans. Few Americans are aware that the photograph shows the flag being raised for a second time. The first flag was too small but the second larger flag would be seen by incoming ships.
Similarly, on the 4th floor of a nursing home, an old woman recalls how the nurses refused to take down the Christmas decorations. In her room, there was only a lone poppy. ‘She often creates stories in her head’, says Mike. ‘You can never really know if what she’s saying is true because her memories are not always real.’
‘Memories are created by altering a set of connections between brain cells so that one cell stimulates the others,’ says Jonah Lehrer, Wired Magazine. By creating memories, we are literally rewiring our brains. Every time a memory is recalled, the connection between brain cells is restructured and the memory altered depending on the stimuli of the current situation. This means that whilst media may fail us, so might our memories.
Will a nation inevitably make the same mistakes because its people cannot remember past experiences or because they replace them with false ones? When asked how memory recall can be assisted, Dr Scerri acknowledges that media is a useful tool in improving memory, as ‘memory albums are extremely valuable for individuals with dementia in facilitating memory events and in reducing anxiety and confusion’. Perhaps these tools can help Mike’s grandmother.
