The shift is usually quiet. It doesn't start with a crash or a theatrical collapse. It starts with a thumb that won't quite grip a coffee mug or a calf muscle that won't stop twitching while you’re trying to watch Netflix. Most people think they’ve just slept wrong. Or maybe it’s carpal tunnel. But for those who eventually hear the words Amyotrophic Lateral Sclerosis, the world splits into two distinct eras: before and after ALS disease. It’s a line in the sand that changes every single metric of a person’s existence, from how they breathe to how they think about the concept of "time."
Honestly, the medical definitions feel a bit hollow when you’re living it. Doctors talk about motor neurons and protein misfolding—specifically the TDP-43 protein—but they don't always talk about the grief of a "before" life that was defined by autonomy.
The Anatomy of "Before": Ignoring the Twitches
In the months leading up to a diagnosis, life feels infinite. You don't think about the fact that your brain is constantly sending electrical signals down your spinal cord to tell your muscles to move. It just happens. This is the before and after ALS disease divide in its purest form—the transition from unconscious movement to manual labor.
Take the case of Steve Gleason, the former NFL player. Before his diagnosis in 2011, his body was his primary tool, a high-performance machine. For the average person, "before" might just mean being able to button a shirt without concentrating. Fasciculations—those tiny, flickering muscle ripples—are often the first red flag. Many patients look back and realize they had these twitches for months. They ignored them. Why wouldn't you? Most twitches are caffeine or stress. But in ALS, these are the sound of motor neurons dying.
Diagnosis itself is a brutal, exhausting process. There is no single blood test for ALS. Instead, it’s a "diagnosis of exclusion." Doctors at places like the Mayo Clinic or Johns Hopkins have to rule out everything else first—Multiple Sclerosis, Lyme disease, vitamin deficiencies, spinal tumors. By the time a patient is told they have ALS, they’ve usually been poked, prodded, and shocked with EMG needles for six months to a year.
The Immediate "After": The Logistics of a New Reality
Once the "after" begins, the psychological weight is heavy. You aren't just dealing with a weak limb; you’re dealing with a ticking clock. The average life expectancy is often cited as two to five years, though people like Stephen Hawking (who lived for decades with a rare, slow-progressing form) prove that the disease is wildly unpredictable.
The first thing that changes in the before and after ALS disease timeline is the house.

Suddenly, stairs are enemies. Hallways are too narrow.
You start looking at your bathroom and realizing it’s a hazard.
It’s expensive.
The ALS Association estimates that the out-of-pocket cost for caring for a patient can exceed $200,000 a year. This isn't just medical bills. It’s the ramp for the front door. It’s the specialized van with the lowered floor. It’s the "Tobii" eye-gaze computer that eventually becomes the only way to talk to your kids.
Why the Legs (or Tongue) Give Out First
ALS usually presents in two ways: limb onset or bulbar onset.
If it’s limb onset, the "after" starts in the hands or feet. You trip over rugs. You drop your keys.
Bulbar onset is arguably crueler. It starts with slurred speech. People might think you’re drunk at a PTA meeting. You struggle to swallow. This version often moves faster, hitting the respiratory system sooner.
The Science of the "After": What’s Actually Happening?
In the "after" phase, the body’s communication lines are being cut. Think of it like a telephone wire. Your brain (the caller) is screaming "Move!" but the wire (the motor neuron) is frayed and broken. The muscle (the receiver) hears nothing. When muscles don't get signals, they wither away. This is atrophy.
Research into the before and after ALS disease progression has shifted toward genetics, even though 90% of cases are "sporadic," meaning there’s no family history. The discovery of the C9orf72 gene mutation was a massive turning point. It’s the most common genetic cause, and it’s helped scientists understand that ALS might actually be a spectrum of diseases rather than one single thing.
We also have new drugs. For decades, we only had Riluzole, which maybe adds a few months to a lifespan. Now, we have Radicava (Edaravone) and newer entries like Tofersen (Qalsody) for specific genetic types. Are they cures? No. But they represent the first real dent in the "after" timeline. They represent a slowing of the decline.

The Invisible Shift: Bulbar Symptoms and Emotional Lability
One of the weirdest parts of the "after" is something called the Pseudobulbar Affect (PBA).
It’s not talked about enough.
Basically, the neurological damage causes a disconnect between your emotions and how you express them. You might start laughing hysterically at a funeral or sobbing because you saw a commercial for detergent. It’s not "depression"—it’s a physical short-circuit in the brain.
Then there’s the breathing.
In the "before" life, you never think about your diaphragm. It’s a muscle like any other. In ALS, as the diaphragm weakens, sleep becomes difficult. You wake up with headaches because you’re retaining carbon dioxide. This is usually when a BiPAP machine enters the bedroom. It’s a non-invasive ventilator that pushes air into the lungs. For many, the BiPAP is the line between "managing" and "surviving."
Navigating the Financial and Emotional Toll
The transition between before and after ALS disease creates a massive identity crisis. If you were the breadwinner, the athlete, or the "handy" person around the house, who are you when you can't hold a hammer?
- The Caregiver Burden: Spouses often become full-time nurses overnight. They learn how to use suction machines to clear saliva because the patient can no longer swallow it. They learn how to administer feeding tube (PEG tube) meals.
- The Social Isolation: Friends sometimes stop calling. Not because they’re mean, but because they’re uncomfortable. They don't know what to say to someone who is literally disappearing in front of them.
- The Equipment Race: You’re always buying gear for a stage the patient is about to enter. You buy the walker while they can still walk, so it’s there for the day they can’t. You order the power wheelchair months in advance because insurance paperwork is a nightmare.
Practical Insights for the "After" Journey
If you or a loved one are navigating the early days of a diagnosis, the "before" can feel like a lost paradise. But the "after" doesn't have to be a void. It requires a different kind of strategy.
1. Get to an ALS Multidisciplinary Clinic. Don't just see a local neurologist. Go to a clinic where a physical therapist, speech-language pathologist, respiratory therapist, and neurologist all see you in one day. Studies consistently show that patients who attend these clinics live longer and have a higher quality of life. They anticipate problems before they become emergencies.
2. Record Your Voice Now. This is vital. While speech is still clear, use "voice banking" technology. You can record hundreds of phrases that a computer can later use to build a synthetic version of your actual voice. It sounds much more like "you" than the generic robotic voices on most tablets.

3. Address the Home Early. Don't wait for a fall to get rid of the throw rugs. If a move to a one-story home is possible, do it sooner rather than later.
4. The Feeding Tube Conversation. Many people are terrified of the PEG tube. They see it as "the end." In reality, many patients find it a huge relief. Eating a meal can take two hours when you have bulbar symptoms, and it’s exhausting. A feeding tube ensures you get the calories and hydration you need without the risk of choking (aspiration pneumonia), which is a leading cause of death in ALS.
5. Legal and End-of-Life Planning. It’s heavy, but necessary. Fill out an Advanced Directive. Decide now how you feel about permanent ventilation (a tracheostomy). Having these decisions made while you can still communicate clearly takes a massive burden off your family later.
The difference between before and after ALS disease is profound, and the "after" is undoubtedly hard. But there is a community of "pALS" (people with ALS) and "cALS" (caregivers) who have mapped this terrain. You aren't the first person to walk this path, and the "after" still contains moments of connection, humor, and even joy, provided you have the right support system in place.
Focus on what can be controlled. You can't control the motor neurons, but you can control the environment, the technology you use to stay connected, and the way you choose to spend the time that remains. Knowledge of the progression is the best tool for reclaiming some sense of agency in a situation that feels fundamentally out of control.
Next Steps for Patients and Families:
Contact the ALS Association or I Am ALS to find a local support group and navigate the complex web of Social Security Disability Insurance (SSDI) benefits, which are expedited for those with an ALS diagnosis. Reach out to Team Gleason if you need assistance with speech-generating devices or specialized equipment that insurance might not cover. Prioritize a consultation with a respiratory therapist to establish a baseline for your lung function, as early intervention with a BiPAP can significantly extend comfort and mobility.
