What Is ALS and How Do Families Plan End of Life?

The short answer: ALS (amyotrophic lateral sclerosis, also known as Lou Gehrig's disease) is a progressive neurological disease that destroys motor neurons, gradually paralyzing the body while leaving the mind intact. Most people with ALS live 2–5 years after diagnosis. Because ALS follows a predictable trajectory and progresses with patients retaining cognitive clarity, it provides a unique — if difficult — opportunity for detailed advance planning while the person is still able to communicate their wishes.

What ALS Does to the Body

ALS progressively destroys the motor neurons that control voluntary muscles. The progression varies by type (limb-onset vs. bulbar-onset) but typically includes:

• Muscle weakness beginning in one limb or in the throat and mouth (bulbar onset)
• Spreading weakness, eventually affecting arms, legs, trunk, and breathing muscles
• Loss of ability to walk, use hands, swallow, and speak
• Respiratory failure — the usual cause of death in ALS
• Cognitive function typically remains intact (though about 15% develop frontotemporal dementia)

The Planning Window

Because ALS progresses predictably and patients typically retain decision-making capacity until late in the disease, there is an unusually clear planning window. Priorities for advance planning in ALS include:

• Advance directive — particularly decisions about respiratory support (non-invasive ventilation via BiPAP vs. invasive ventilation via tracheostomy)
• POLST/MOST — physician orders for specific interventions at specific disease stages
• Communication planning — eye-gaze devices, AAC (augmentative and alternative communication) devices to preserve communication capacity after speech is lost
• Legacy work — recording stories, writing letters, creating video messages while speech is still possible
• Hospice timing — ALS typically qualifies for hospice when respiratory or nutritional function is critically impaired; many advocates recommend earlier enrollment

The Ventilator Decision

One of the most significant decisions in ALS is whether to use invasive mechanical ventilation (tracheostomy) when breathing fails. This can significantly extend life but may not improve quality of life and makes death more complex to manage. The ALS Association provides resources for this decision. Many patients choose non-invasive ventilation (BiPAP) as a bridge but decline tracheostomy.

How a Death Doula Can Help

Death doulas can provide invaluable support to ALS patients and families — facilitating legacy work while communication is still possible, supporting advance care planning conversations, coordinating vigil planning, and providing respite support as the disease progresses. The predictable trajectory of ALS makes doula involvement particularly meaningful and effective.

Frequently Asked Questions

Does Medicare cover ALS hospice?

Yes — ALS is a qualifying diagnosis for Medicare hospice. In fact, ALS was explicitly covered under special provisions that allow hospice enrollment earlier than the standard 6-month prognosis requirement, given the disease's predictable trajectory.

When should someone with ALS go on hospice?

The ALS Association recommends discussing hospice earlier rather than waiting for crisis. Hospice is typically considered when respiratory function (FVC below 50%) or nutritional function is significantly impaired. Earlier enrollment allows more time to benefit from the full hospice support package.

What is BiPAP and how does it help ALS patients?

BiPAP (Bilevel Positive Airway Pressure) is a non-invasive ventilation mask that supports breathing when the respiratory muscles weaken. It significantly improves quality of life and can extend life in ALS by months to years. It does not require surgery and can be used at home.

How do ALS patients communicate when they lose speech?

Communication technology for ALS includes: text-to-speech software, eye-gaze devices (that track eye movement to operate a keyboard), brain-computer interfaces (experimental), and pre-recorded voice banks (using the person's own voice before it changes). Plan ahead — these devices work best when introduced before communication is severely affected.

What legacy work can an ALS patient do?

While speech and mobility allow: record video messages for family milestones (weddings, graduations), record an oral history, write letters to children or grandchildren, complete an ethical will, create a memoir. A death doula can help facilitate this work while the window is open.
