Narcolepsy affects daily life mainly due to extreme daytime sleepiness, which makes it difficult to concentrate and can cause the person to suddenly fall asleep at any time or place. This can interfere with basic activities such as working, studying, talking, or even driving, posing a safety risk.

More than serious, it is annoying, because a disorder that prevents you from staying awake during the day, disrupts nighttime sleep, and in some cases, causes sudden muscle weakness that leads to collapse. It can even cause sudden loss of muscle tone (cataplexy) and hallucinations.

People with narcolepsy may also face social and emotional difficulties, as the disease can be misinterpreted and lead to problems in personal and work relationships due to drowsiness and unpredictable episodes.

The novelty is that orexin agonists, such as TAK-861, are showing promising results in phase 2 clinical trials and could become a fundamental treatment for narcolepsy.

Impact on daily life

Narcolepsy generates significant challenges in multiple aspects of daily life:

In the workplace and academic settings, people with narcolepsy face difficulties maintaining concentration for prolonged periods. Episodes of sudden sleep can interrupt presentations, meetings, or classes, which can affect professional or academic performance. Many people develop strategies such as scheduling short naps or seeking jobs with flexible hours.

In interpersonal relationships, this disorder can lead to misunderstandings. Symptoms such as falling asleep during conversations or social activities can be misinterpreted as disinterest or disrespect. This requires open communication with family, friends, and colleagues about the medical nature of these episodes.

Personal safety is a constant concern,especially when driving or operating machinery. Cataplexy episodes, which cause a sudden loss of muscle tone, can be particularly dangerous in certain situations.

Emotional well-being is also affected. Many people experience frustration, anxiety, or depression due to the limitations imposed by the disorder and the challenges in maintaining normal routines.

Recreational activities require adapting schedules and carefully choosing activities, prioritizing those that allow for breaks or are less risky in the event of a sleep episode.

Despite these challenges, with appropriate medical treatment, lifestyle modifications, and a good support system, many people with narcolepsy manage to lead full and productive lives.

Hopeful drug to treat narcolepsy

Recent studies have sought to demonstrate how effective the drug TAK-861, from Takeda Pharmaceuticals, is in treating narcolepsy. It has been used to improve excessive daytime sleepiness (called excessive daytime sleepiness or EDS) after 3 months of treatment.

It has also been shown to reduce the number of sudden, unexpected attacks of muscle weakness (cataplexy).

It is being tested primarily for efficacy and safety in people with narcolepsy type 1 and may offer hope for patients.

Oveporexton, as it is also known, is designed to directly target orexin deficiency in narcolepsy type 1 by selectively stimulating the orexin 2 receptor.

“The data indicate that restoring orexin signaling has the potential to help people with narcolepsy type 1 achieve levels of wakefulness close to those found in healthy individuals, while also having a positive impact across the broader spectrum of the disease,” she told Medscape Medical News Dr. Sarah Sheikh, study co-author and head of the Neuroscience and Global Development Therapeutic Area Unit at Takeda.

How is narcolepsy diagnosed?

The diagnosis of narcolepsy is primarily made through a sleep study, which includes two key tests: overnight polysomnography and multiple sleep latency testing (MSLT).

Polysomnography is a study that records different physiological parameters during nighttime sleep, such as brain waves, heart rate, breathing, and muscle and eye movements. This test helps rule out other causes of sleepiness and assess sleep architecture.

While TLMS measures how long it takes a person to fall asleep during several scheduled naps throughout the day, 4-5 naps of 20 minutes are usually taken, spaced two hours apart. In people with narcolepsy, the mean sleep latency is less than or equal to 8 minutes, and rapid entry into REM sleep is observed on at least two occasions.

Additionally, the diagnosis may be supported by a clinical history, which includes symptoms such as excessive daytime sleepiness and cataplexy (sudden loss of muscle tone). In some cases, genetic testing may be performed to identify a predisposition, and in specialized centers, a lumbar puncture may be performed to measure low levels of hypocretin in the cerebrospinal fluid, a specific marker for narcolepsy type 1.

Other tests, such as an electrocardiogram (ECG) and electroencephalogram (EEG), can complement the evaluation to rule out other diseases.

Alternative treatment to drugs

Alternative treatments to drugs are available to manage narcolepsy, which mainly include lifestyle changes and complementary therapies. Recommendations for non-pharmacological management include:

In addition, emotional support, education about the disease, and communication with employers or teachers to adapt daily activities are also important for effective non-pharmacological management.

These approaches can complement or, in some cases, help reduce the need for medication, but they generally do not completely replace pharmacological treatment, which is often necessary in narcolepsy to control the most severe symptoms.
