The 7 Stages of Bulbar ALS

6 min read
Summary

Bulbar ALS affects speech and swallowing early, progressing through seven stages with distinct communication and nutritional challenges. ALS United's multidisciplinary care approach empowers patients and families with specialized support, early intervention strategies, and coordinated resources at every stage.

Understanding Bulbar ALS: What Happens in the First Stage

Bulbar ALS typically begins with speech changes--slurred or slowed speech appearing months or years before diagnosis--giving you and your care team time to plan ahead.

How bulbar ALS differs from other forms of ALS

ALS has two primary onset types: limb onset, where weakness begins in the arms or legs, and [bulbar onset](https://alsunited.org/blog/understanding-bulbar-als), where the first symptoms appear in the muscles that control speech and swallowing. [1] Bulbar ALS is less common -- limb onset accounts for the majority of cases -- but speech and swallowing difficulties emerge as defining early features rather than limb weakness. [1] The distinction matters clinically: bulbar onset means motor neuron degeneration begins in the brainstem's bulbar region, which governs mouth, throat, and facial muscle function. [2] As a result, people with bulbar ALS typically face communication and nutrition challenges earlier in the disease course than those with limb-onset ALS. [2]

Why the bulbar region is so critical to daily function

The bulbar region is a section of the brainstem that controls the motor neurons driving speech, swallowing, chewing, and breathing. [4] These aren't optional functions -- they're the mechanics of eating, communicating, and staying alive, performed automatically dozens of times each day. When motor neurons in this region degenerate, the muscles of the lips, tongue, soft palate, jaw, and voice box gradually lose strength and coordination. [3] This is why damage to the bulbar region creates such immediate, wide-ranging effects: it disrupts multiple essential daily functions simultaneously, often before any limb weakness appears. [4]

Stage 1: Initial symptoms and early warning signs you shouldn't ignore

The first signs of bulbar ALS are almost always speech-related -- speech problems are eight times more common than swallowing difficulties as the initial symptom of this condition. [5] Early changes typically include slowed or slurred speech, poor articulation, reduced voice volume, and shifts in voice quality such as hoarseness or breathiness, sometimes appearing up to three years before a formal diagnosis is made. [4] Subtle swallowing difficulties may also be present at this stage, though they're often mild enough to go unnoticed. [4] Because these [very early ALS symptoms](https://alsunited.org/blog/very-early-als-symptoms-what-to-look-out-for) can be mistaken for other conditions or dismissed as stress, any persistent change in speech or voice warrants prompt evaluation by a neurologist. [5]

Stages 2 Through 4: Progressive Speech and Swallowing Changes

Speech therapists and dietary modifications can help you manage swallowing changes and reduce aspiration risk as bulbar ALS progresses through stages 2 through 4.

Stage 2: Noticeable slurring and difficulty with certain foods

By Stage 2 of bulbar ALS, speech changes that may have seemed intermittent in Stage 1 become consistent and noticeable to others -- slurred speech, poor articulation, and difficulty forming certain words are now present in most conversations. [5] Swallowing difficulties also emerge more clearly at this stage, particularly with foods that are hard, dry, or require sustained chewing, as [tongue and throat muscle weakness](https://alsunited.org/blog/als-tongue-symptoms/) disrupts the coordination needed to move food safely. [5] These early swallowing changes increase the risk of aspiration -- food or liquid entering the windpipe -- which can trigger coughing and raise concerns about adequate nutrition. [5] Working with a speech therapist at this stage can help assess swallowing function and identify which food textures are safest to eat. [6]

Stage 3: Significant speech decline and increased choking risk

By Stage 3, speech decline in bulbar ALS has become pronounced -- muscle weakness in the lips, tongue, and soft palate now makes words harder to form, and speaking fatigue causes many people to use shorter sentences and speak less often. [5] Swallowing difficulties intensify at this stage, with thin liquids posing a particular aspiration risk alongside harder or drier foods, and choking episodes become more frequent. [5] Modified dietary textures such as thickened liquids and pureed foods, combined with postural adjustments during meals, can reduce aspiration risk and help maintain adequate nutrition. [7] A [cough assist machine](https://alsunited.org/blog/cough-assist-machine/) can also help clear secretions from the airway when a weakened cough makes this difficult on its own. [7]

Stage 4: Severe communication challenges and nutritional concerns

By Stage 4, speech in bulbar ALS has declined to the point where intelligibility becomes severely limited -- when speech rate falls below 100 words per minute, introducing augmentative and alternative communication (AAC) devices becomes appropriate, and early access to these tools has been shown to improve quality of life. [8] Nutritional concerns also intensify at this stage: compensatory strategies like thickened liquids, high-calorie supplements, and supervised swallowing are often no longer enough to prevent continued weight loss, and enteral tube feeding -- typically via a percutaneous gastrostomy (PEG) -- becomes a serious consideration. [9] Weight loss and malnutrition are linked to shortened survival in ALS, making early care planning critical -- tube placement is ideally done while forced vital capacity (FVC) remains above 50%, when the procedure carries fewer risks. [10]

Stages 5 Through 7: Advanced Bulbar ALS and End-of-Life Considerations

Eye-tracking communication systems become indispensable as bulbar ALS progresses, allowing you to maintain connection with loved ones when natural speech is no longer possible.

Stage 5: Loss of intelligible speech and tube feeding necessity

Stage 5 of bulbar ALS marks the point at which speech becomes fully unintelligible, making AAC devices -- which should already be in use from Stage 4 -- the sole means of communication. [11] Oral feeding is no longer sufficient at this stage: muscle weakness in the throat and mouth makes swallowing dangerous, and enteral tube feeding transitions from a planned intervention to an immediate nutritional necessity. [13] When a feeding tube hasn't yet been placed and FVC has fallen below 50%, RIG is generally the safer option over PEG because it doesn't require sedation. [12] For families navigating these decisions, understanding how [ALS life expectancy](https://alsunited.org/blog/understanding-als-life-expectancy-a-comprehensive-guide/) is shaped by nutritional and respiratory status can clarify why acting early on tube placement matters. [12]

Stage 6: Complete loss of verbal communication and respiratory involvement

Stage 6 marks complete anarthria -- the total loss of natural speech -- alongside respiratory involvement significant enough to require active decisions about mechanical ventilation. [14] Eye-tracking communication systems are the primary AAC tool at this stage; in severe bulbar ALS, users consistently rate these devices as indispensable for daily life, and communicative ability measurably declines when they are unavailable. [14] Respiratory decline may progress to the point where tracheostomy-based invasive ventilation becomes necessary, a milestone that affects which communication devices remain accessible and requires careful coordination across the full care team. [14] Connecting with [ALS support resources](https://alsunited.org/blog/als-support-essential-resources-for-patients-and-families/) at this stage can help families navigate both respiratory care decisions and communication planning together.

Stage 7: End-stage bulbar ALS and palliative care pathways

Stage 7 marks the point where care focus shifts entirely to comfort, symptom relief, and family support -- the core of palliative and hospice care. Air hunger from ventilatory failure affects up to 85% of patients at this stage, and pain occurs in up to 80%; opioids, including morphine, are commonly used to manage both, with morphine shown to be safe and effective for dyspnea relief in this population. [16] Disease-modifying medications like riluzole are generally discontinued at hospice enrollment, since their modest benefits are more relevant earlier in the disease. [16] Hospice care -- available at home, in a dedicated facility, or in a hospital -- includes nursing, medication management, counseling, and spiritual support for both the person with bulbar ALS and their family; [resources on coping and understanding](https://alsunited.org/blog/literature-for-coping-and-understanding) can offer additional guidance through this period.

How ALS United's clinic finder connects you with specialized bulbar care

The ALS United clinic finder connects people living with bulbar ALS to [partner clinics](https://alsunited.org/blog/our-care-services) that follow the multidisciplinary care model -- the gold standard for ALS care -- which research has associated with improved quality of life and extended survival through coordinated access to treatment and support. [18] These clinics bring together speech pathologists who evaluate swallowing and communication, registered dietitians who manage nutrition across every stage, and respiratory therapists who monitor breathing function -- the specialists most directly relevant to bulbar ALS progression. [17] For people in rural or geographically isolated areas, virtual clinic visits available through many partner clinics ensure that distance doesn't limit access to this level of coordinated, bulbar-specific care. [18]

Speech therapy, nutrition support, and counseling services available through ALS United

Speech therapists in our care network assess communication early, guide patients through AAC options and voice banking, and provide compensatory swallowing strategies as bulbar ALS advances. [20] Registered dietitians address weight management, meal texture modifications, high-calorie supplementation, and tube feeding transitions across all stages. [19] Social workers and counselors help patients and families navigate diagnosis, plan for evolving care needs, and connect with [ALS support groups](https://alsunited.org/blog/als-support-groups-connecting-with-others-facing-the-disease/) that offer peer connection throughout the journey. [6] We are here for you at every stage -- because no one should navigate bulbar ALS alone.

Building your care team and accessing community support throughout all stages

Building a care team for bulbar ALS works best when it starts early -- ahead of each new stage, not after the need becomes urgent. Multidisciplinary care has been shown to decrease one-year mortality by as much as 30 percent, reduce hospitalizations, and improve quality-of-life outcomes, yet only about 40 percent of people with ALS in the United States currently access this level of coordinated care. [22] Alongside clinical support, peer connection matters: [joining an ALS support group](https://alsunited.org/blog/join-a-support-group) gives patients and families a space to share practical strategies and process the emotional weight of each stage. [21] We are here for you -- together in the fight, no one should face bulbar ALS without a team around them.

  1. It initially manifests one of two ways: as weakness in the limbs, called limb (or spinal) onset, or difficulty in speaking or swallowing, termed bulbar onset. Limb onset is far more common. Bulbar-onset ALS begins in the face or neck. Early symptoms include slurred speech and hoarseness.
  2. There are two general types of ALS onset: limb and bulbar. In limb-onset, the first symptoms will be in the arms or legs and start with weakness, tripping or stumbling or a reduction in fine manual dexterity. In bulbar-onset, the first symptoms will be difficulty in speaking or swallowing.
  3. ALS leads to the degeneration of the nerve cells responsible for bringing messages from the lower parts of the brain (bulbar region) to the muscles of the lips, tongue, soft palate, jaw and voice box.
  4. Bulbar onset ALS primarily affects motor neurons in the bulbar region of the brainstem, which controls the muscles supporting functions such as speech, swallowing, and chewing.
  5. Speech problems are eight times more common than swallowing problems as the first symptom of bulbar-onset ALS.
  6. Working with a speech therapist can help people with bulbar-onset ALS restore their communication function. It can also help assess swallowing and provide tips for safer swallowing. Nutritionists can help people with bulbar-onset ALS plan their meals and provide education on how to avoid foods that are difficult to swallow.
  7. individuals with difficulty swallowing may use modified dietary textures (e.g., thickened liquids, pureed foods) and postural techniques to reduce the risk of choking and aspiration pneumonia.
  8. Since speech rate is a relatively good predictor of the deterioration in intelligibility in patients with spinal, bulbar, or mixed ALS, it is necessary to start providing aids for alternative communication in good time if the dysarthria progresses and the ALS patient's speech rate falls below 100 words per minute. For patients with the beginning of impairment of speech and preserved ability to use a touchscreen communication device, early access has been shown to positively influence the quality of life.
  9. As disease progress, bulbar symptoms, dysphagia, and general weakness for oral nutrition can worsened. In this case, initial support such as high caloric supplements, thickening of liquids and chaperoned swallowing training are not anymore able to compensate for weight loss or swallowing difficulties. Nutrition via a percutaneous gastrostomy (PEG), radiologically inserted gastrostomy (RIG), or nasogastric tube (NGT) must then be considered.
  10. Weight loss and malnutrition are associated with shortened survival times in ALS. In general, feeding tubes should be placed when FVC is greater than 50% since doing so is associated with fewer complications.
  11. Mandatory Gastrostomy Stage ALS -- As swallowing becomes increasingly difficult, maintaining proper nutrition becomes a challenge. The mandatory gastrostomy stage addresses this issue by the introduction of a feeding tube to ensure adequate nutrition and hydration.
  12. For patients with a FVC less than 50%, RIG may be a better choice as it does not require sedation. Enteral tube feeding should be considered in patients who experience weight loss, significant dysphagia, and significant burden with oral intake.
  13. Weakness of the muscles that control chewing and swallowing makes it dangerous to eat and drink due to a high risk of choking.

  15. Hospice care can be provided in the patient's home, a hospice center, or a hospital. Care may include nursing, medication management, counseling, and spiritual support. Hospice aims to improve a patient's quality of life by managing symptoms, providing holistic care, and supporting the family through this difficult time.
  16. Dyspnea Air hunger due to ventilatory failure is common in the later stages of ALS, occurring in up to 85% of patients. Pain occurs in up to 80% of patients. One small, non-randomized prospective study demonstrated that morphine appears to be both safe and effective in this patient population. Although there are no published guidelines, it is reasonable to discontinue these medications when a person living with ALS becomes ventilator-dependent, or at the time of hospice enrollment.
  17. A speech pathologist evaluates speech and swallowing difficulties related to ALS, and makes recommendations for technologies that assist ALS patients to communicate. A registered dietitian provides practical advice and counseling to ALS patients and caregivers about food and diet to maintain adequate nutrition and hydration. A respiratory therapist evaluates breathing function in patients with ALS and makes recommendations for assistive devices.
  18. Multiple studies have shown that the multidisciplinary ALS clinic model is the gold standard for ALS care. This model not only supports a whole-person approach tailored to the unique needs of each individual but has also been associated with improved quality of life and extended survival due to coordinated access to treatments, support, and resources. Virtual clinic visits also play a critical role in expanding access, particularly for individuals living in rural or geographically isolated areas.
