Rare Disease Day is held on the last day of February every year to raise awareness of rare diseases.
Idiopathic Hypersomnia is a rare disease. It is also one of the most misunderstood and under researched sleep disorders. Many (including doctors) incorrectly think it refers to any case of excessive daytime sleepiness (EDS) that cannot be explained by another preexisting medical condition or sleep disorder or by lifestyle or behavior. This is not correct; Idiopathic Hypersomnia is a rare neurological sleep/wake disorder. EDS is just one symptom of Idiopathic Hypersomnia. Idiopathic Hypersomnia is characterised by a number of symptoms and clinical features first defined by Bedrich Roth more than 40 years ago. Roth’s years of extensive research that led to his description of Idiopathic Hypersomnia as a separate disease entity was accepted and included in the first ICSD (International Classification of Sleep Disorders), the Diagnostic Classification of Sleep and Arousal Disorders in 1979. Since then it has been included as a “Rare Disease” on the Genetic and Rare Diseases Information Center (GARD) register and Orphanet.
For most people living with a rare disease, as well as their family members or carers, the reality of daily life can include any combination of the following: collecting and taking medicines, attending appointments, participating in physical therapy, using specialist equipment, and accessing various social and community support services and respite care. Managing these care-related tasks alongside their usual daily activities such as work, school, and leisure time can be challenging.
Organising care can involve researching local services, making phone calls, accessing treatments and rehabilitation, handling administrative procedures, and adapting the home or workspace. As a consequence, people living with a rare disease are often off work or school. It becomes a complex and frustrating process especially when a lack of coordination across services means having to repeat the same information over and over again. This is particularly hard for someone with Idiopathic Hypersomnia as the very nature of the disease means they lack quality wakefulness and battle against constant debilitating excessive daytime sleepiness.
"Imagine going to see your doctor only to be told that they don’t know what is happening to your body, that they don’t know what your disease is. Imagine that they can diagnose your disease but tell you that there is no cure... Or that the treatment available is not fully effective but it is the option available. You don’t know how you or your loved one will manage life from one day to the next, nor how the disease will affect your work, school or social life. This is the reality for many rare disease patients.” - Quote from Rare Disease Day 2017.
There are many misconceptions about Idiopathic Hypersomnia. This combined with inappropriate testing methods has resulted in Idiopathic Hypersomnia being one of the most misdiagnosed of all neurological sleep disorders. The impact of this as well as the patients that continue to go undiagnosed for these same reasons is immeasurable. Further research is desperately needed in all areas, ie: etiology, epidemiology, and the genetic aspects of the disease and to identify biomarkers that will lead to better more appropriate diagnostic tools.
