Narcolepsy is often misunderstood, with persistent stigma surrounding this and other 睡眠 disorders. Incorrectly dismissed as “睡眠iness,” narcolepsy is a chronic neurological condition impacting up to an estimated 170,000 people in the United States1 that impairs regulation of the 睡眠-wake cycle and takes an immense toll on daily life. The journey to diagnosis can be long and can be marked by skepticism from authority figures and low self-esteem2 before finally reaching an accurate answer.
As we recognize World Narcolepsy Day, we join the 睡眠 community in efforts to raise awareness and end common misperceptions about this disease. One way we do this is by gathering insights directly from people living with narcolepsy to better understand the substantial and often untold burden narcolepsy and its symptoms place on many facets of life – physical, 情感, 社会, 专业, and financial – even after diagnosis and treatment.
Earlier this month, 澳门赌城官方官网注册 presented new findings at the 36th Annual Psych Congress from recent patient interviews evaluating the diagnosis journey and symptoms of people living with narcolepsy (type 1 [NT1], n=12; type 2 [NT2], n=10).3 The results highlight common symptoms of the disease and underscore patients’ unique journeys to diagnosis.
Across both narcolepsy types interviewed in our study, many participants (50% for NT1 and 60% for NT2) reported receiving their narcolepsy diagnosis at least 10 years or longer after they first began experiencing symptoms. Many were misdiagnosed at least once during that time, receiving diagnoses including depression, 睡眠呼吸暂停, and attention-deficit/hyperactivity disorder (ADHD). Patients also reported visiting several different types of healthcare 专业s while seeking a diagnosis, including 睡眠 specialists, 神经学家, 位肺脏, psychiatrists and primary care physicians.3
The three most commonly reported narcolepsy symptoms across these interviews included excessive daytime 睡眠iness, cognitive impairment, 和疲劳. While excessive daytime 睡眠iness 和疲劳 are commonly associated with the public perception of narcolepsy, cognitive and mental symptoms receive less recognition but can be just as taxing. These include brain fog, difficulty concentrating, memory loss and hallucinations.4
Consistent with the diagnostic criteria, all interview participants with NT1 reported cataplexy – a sudden, 自发的, and temporary loss of muscle tone, commonly triggered by strong emotions or reactions such as laughter, 愤怒, stress and surprise.5
The road to a narcolepsy diagnosis can be long and frustrating, often spanning many years and visits to several specialists, with delays and misdiagnoses more common than not. Many people may remain undiagnosed due to low awareness about the disorder among both patients and healthcare providers.2
在澳门赌城官方官网注册公司, we believe that better representation and advocacy for people living with narcolepsy can help increase acceptance and understanding of the burden caused by this and other 睡眠 disorders. We’re integrating these real-world accounts and patient insights into our clinical development process as we continue our commitment to improving care for and understanding the unique needs of people living with psychiatric and neurological disorders – including narcolepsy.
