Sleep disturbances are prevalent among patients with amyotrophic lateral sclerosis (ALS), a progressive motor neuron disease that causes generalized muscle weakness and premature death. The connection between ALS and sleep is bidirectional: while ALS can lead to sleep problems, lack of sleep can worsen ALS symptoms and affect disease progression and survival time. This highlights the importance of addressing sleep issues in ALS patients to improve their quality of life. Various factors, including physical symptoms, respiratory issues, and mental health conditions, can contribute to sleep disturbances in ALS patients. Treatment options range from medication to respiratory support and adjustments to sleep environments.

Sleep disturbances in ALS patients
Sleep disturbances are extremely common in patients with ALS, affecting around 70% of patients and substantially adding to the burden of the disease for both patients and caregivers. The causes of these disturbances are varied and often interrelated, and they can be difficult to treat due to their similarity to ALS symptoms.
Firstly, ALS causes physical symptoms that can disrupt sleep, including muscle cramps, pain, reduced mobility, spasticity, mucus retention, and restless legs syndrome. The latter two can cause sleep apnea and sleep-related hypoventilation, which are common among people with ALS. This involves shallow breathing during sleep, which leads to higher carbon dioxide levels in the blood. This can be treated with non-invasive ventilation (NIV) using a facial mask, which has been shown to improve the lifespan of ALS patients. A bilevel machine, or BiPAP, can also assist with breathing during sleep by delivering pressurised air through a mask.
Secondly, mental health issues such as depression, anxiety, fear, and grief can lead to insomnia in ALS patients. This can be treated with anti-anxiety medication, although this should be used sparingly and only when appropriate.
Thirdly, sleep disturbances can be caused by the progression of ALS itself, as symptoms such as breathing problems, muscle pain, and immobility can make it hard to fall asleep or stay asleep. This can create a cycle where sleep problems aggravate ALS symptoms, which then leads to more sleep problems.
Finally, emerging evidence suggests that ALS-related sleep disturbances may be linked to the hypothalamus, a brain region that plays a critical role in sleep-wake regulation. A growing body of literature has documented hypothalamic dysfunction in ALS patients, indicating that this may play a key role in the sleep disturbances they experience.
Overall, the treatment of sleep disturbances in ALS patients is focused on improving quality of life, as there is currently no cure for ALS. This involves systematically looking for treatable problems and symptoms, and addressing them through medication, ventilation, or other means.

Breathing issues and ALS
Amyotrophic lateral sclerosis (ALS) is a progressive, fatal, degenerative disorder that leads to the death of upper and lower motor neurons. The condition causes a variety of sleep disturbances, including insomnia, sleep apnea, sleep-related hypoventilation, and abnormal sleep patterns. These sleep issues can be caused by ALS, aggravated by it, or be unrelated.
Breathing issues are a common symptom of ALS, and they can also affect sleep. Respiratory muscles can weaken, making it difficult to cough up phlegm from the lungs, which can then get caught in the throat and interfere with breathing and sleep. Secretions in the throat can also affect swallowing, leading to saliva pooling in the mouth and causing drooling, which can also disrupt sleep.
There are several ways to manage breathing issues and improve sleep quality for people with ALS. A bilevel breathing machine (BiPAP) can assist with inhaling and exhaling during sleep and is recommended before breathing difficulties arise. Cough assist and suction machines can help clear secretions before bed. Adjustable beds, comfortable sleepwear, and specific pillows can also enhance sleep comfort.
Medications can be used to treat sleep issues in ALS patients, but they should be used sparingly and under medical guidance. Anti-anxiety medication and drying medications can help, but the latter can have side effects. The FDA-approved medications riluzole (Rilutek, Tiglutik) and edaravone (Radicava) are also used to treat ALS, with the former showing efficacy in extending life. Tofersen, an antisense oligonucleotide, is another FDA-approved treatment for ALS patients with the SOD1 gene.
Overall, good sleep is critical for the quality of life of ALS patients, and appropriate treatments should be sought if sleep issues arise.

FDA-approved ALS medications
While there is no mention of sleeping pills per se, there are a few medications that have been approved by the FDA to treat ALS. These include riluzole (Rilutek, Tiglutik), edaravone (Radicava), and Qalsody. Riluzole is available as a pill, liquid, or dissolvable oral film and is taken twice a day. It is well-tolerated, with mild nausea or fatigue as possible side effects. Tiglutik is a liquid form of riluzole that is easy to swallow and suitable for patients with swallowing difficulties. Radicava was initially administered intravenously, but a more user-friendly oral gel version, Radicava ORS, was approved in 2022. It is designed to slow the progression of ALS by preventing nerve damage. Qalsody is a genetically targeted therapy approved by the FDA in 2023 to treat ALS associated with a mutation in the superoxide dismutase 1 (SOD1) gene.
In addition to these medications, ALS patients may benefit from using a bilevel machine (BiPAP) to assist with breathing during sleep. This can improve quality of life and prolong survival. Additionally, a cough assist machine and suction machine can help clear phlegm and secretions before bedtime, improving sleep quality. While not FDA-approved treatments, these machines can be prescribed by a neurologist and covered by insurance.
It is important to note that medications for insomnia in ALS patients, such as amitriptyline and zolpidem, are recommended to be used sparingly and only when appropriate, under the guidance of a neurologist or mental health professional.

Over-the-counter sleep medications
While there is no mention of ALS patients taking sleeping pills, it is important to note that ALS patients experience a range of symptoms that can affect their sleep, including respiratory issues, difficulty swallowing, and excessive secretions. To improve sleep quality, ALS patients are often advised to use a bilevel machine (BiPAP) to assist with breathing during sleep. This machine delivers pressurized air to aid in inhaling and exhaling, improving quality of life. Additionally, ALS patients may benefit from using a cough assist machine and suction machine before bed to clear phlegm and secretions.
For individuals with sleep difficulties, there are various over-the-counter (OTC) sleep medications available. These non-prescription sleep aids often contain antihistamines, which can cause drowsiness as a side effect. Diphenhydramine and doxylamine succinate are common sedating antihistamines found in OTC sleep aids. While these medications can help with occasional sleeplessness, they are not recommended for regular use due to potential side effects and risks, including anticholinergic properties that may increase the risk of dementia with long-term use.
Natural remedies such as melatonin and valerian supplements are also popular OTC options for improving sleep. Melatonin is a naturally occurring hormone that promotes sleep, while valerian is an herb that aids relaxation. It is always advisable to consult a healthcare provider before taking any OTC sleep medication to ensure safety and avoid potential drug interactions.
Additionally, good sleep habits, also known as sleep hygiene, play a crucial role in improving sleep quality. This includes maintaining a consistent sleep schedule, creating a relaxing bedtime routine, and ensuring a comfortable sleep environment. While OTC sleep medications can provide temporary relief from sleeplessness, addressing underlying sleep issues and maintaining healthy sleep habits are essential for long-term sleep health.

ALS and palliative care
Amyotrophic lateral sclerosis (ALS) is a progressive, fatal, degenerative disorder that leads to the death of upper and lower motor neurons. It is an incurable neurodegenerative disease that causes nerve cells in parts of the brain and spinal cord to die. As a result, voluntary muscle action is affected, and patients in the later stages of the disease may become totally paralyzed.
Palliative care is a whole-person approach to care that focuses on improving the quality of life for both the patient and their family. It aims to relieve pain and symptoms and reduce emotional distress for a person living with a serious illness or disease like ALS. Palliative care can be provided at any age and stage of the illness, even while the patient receives other treatments.
For people living with ALS, palliative care can be beneficial as soon as they are diagnosed. Palliative care professionals can help them understand ALS and its likely progression, as well as the interventions that can manage the symptoms they might face. They can also help patients maintain their function and strength for as long as possible. Additionally, palliative care specialists can help patients determine what everyday things matter to them and support them in sharing their medical wishes with their loved ones.
Palliative care teams work in partnership with the patient, their neurologist, and other doctors to manage symptoms, communication, and the coordination of care. They are well-versed in navigating the complex healthcare system and can provide an extra layer of support. They help patients and their loved ones make both small and large decisions, enhancing communication between the patient, their family, and their doctors. They also guide patients through the process of advanced care planning, including decisions about the use of mechanical ventilation, artificial feeding, and hydration.
Evidence suggests that people living with ALS who receive palliative care have improved survival compared to those who receive care only from general neurology clinics. Palliative care physicians may provide advice on diet, supplements, exercise, and common medication interventions.
