7 Early Signs of ALS Often Missed
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, affects approximately 5,000 people in the United States each year, with more than 20,000 individuals currently living with the disease. ALS is a progressive neurodegenerative disorder that attacks nerve cells in the brain and spinal cord, leading to muscle weakness, loss of mobility, and ultimately, respiratory failure. Unfortunately, ALS is notoriously difficult to diagnose in its early stages, as its symptoms often resemble those of other less severe conditions. As a result, many individuals live with subtle signs of ALS for months or even years before receiving a proper diagnosis.
In its early stages, ALS can be easily overlooked, as the symptoms may seem minor or be attributed to normal aging or other more common health issues. Early recognition is critical because, although there is no cure, early intervention can help manage symptoms, improve quality of life, and potentially slow the progression of the disease. Understanding the early warning signs of ALS is vital for anyone concerned about their health or the health of a loved one. By being aware of these often-missed symptoms, individuals can seek medical attention sooner, increasing their chances of better care and support.
In this article, we’ll explore seven early signs of ALS that are frequently missed, helping to raise awareness and encourage proactive health monitoring for those at risk.
What is Amyotrophic Lateral Sclerosis (ALS)?
Amyotrophic Lateral Sclerosis (ALS) is a fatal, progressive neurodegenerative disease that specifically attacks and destroys the nerve cells, known as motor neurons, which control voluntary muscle movements like walking, talking, and breathing. To understand this complex disease better, it is essential to examine how it systematically breaks down the body’s communication network between the brain and muscles and to contextualize its prevalence within the broader landscape of neurological disorders.
ALS Affects the Brain and Muscles
ALS affects the brain and muscles by systematically destroying both upper motor neurons in the brain and lower motor neurons in the spinal cord, severing the communication link that enables voluntary movement. This disruption prevents the brain from initiating and controlling muscle function, leading to progressive weakness, muscle atrophy, and eventual paralysis.
Moreover, the process unfolds as a two-part failure in the body’s intricate command system for movement. Upper motor neurons, located in the brain’s motor cortex, act as the initial messengers, sending signals down the spinal cord. Lower motor neurons, located in the brainstem and spinal cord, receive these signals and transmit them directly to the muscles, causing them to contract.
In a person with ALS, these motor neurons begin to degenerate and die for reasons that are still not fully understood. As the upper motor neurons deteriorate, the primary symptoms that emerge are muscle stiffness (spasticity) and exaggerated reflexes. The brain is sending signals, but they are poorly regulated and uncontrolled. Conversely, as the lower motor neurons die off, the muscles no longer receive any signals to move. This leads to profound muscle weakness, visible twitching under the skin (fasciculations), and significant muscle wasting, or atrophy, because the muscles are no longer being stimulated.
Ultimately, ALS involves the progressive failure of both systems. The brain loses its ability to send clear commands, and the pathway to execute those commands is simultaneously destroyed. The sensory nerves, however, which control sight, sound, smell, taste, and touch, typically remain intact. This creates the devastating reality where the individual’s mind remains sharp and aware while their body becomes progressively immobile.
Is ALS a Common or Rare Disease?
ALS is considered a rare disease, with a relatively low prevalence and incidence rate compared to other neurological conditions like Alzheimer’s or Parkinson’s disease. Its rarity is one of the factors that can contribute to a lack of public awareness and, at times, delayed diagnosis, as its symptoms are not as widely recognized. According to the Centers for Disease Control and Prevention (CDC), the incidence of ALS in the United States is approximately 1.6 to 2.4 per 100,000 people per year. This means that roughly 5,000 to 6,000 new cases are diagnosed annually in the U.S.
The prevalence, which is the total number of people living with the disease at any given time, is estimated to be between 4 and 6 per 100,000 people. This translates to an estimated 16,000 to 20,000 Americans living with ALS. Globally, the incidence rates are similar in populations of European descent, though they can vary in other ethnic groups. ALS can affect anyone, regardless of race, ethnicity, or socioeconomic status. However, it most commonly develops between the ages of 40 and 70, with a peak onset around age 60.
There is a slight male predominance, with men being about 1.2 times more likely to develop the disease than women, although this difference narrows with increasing age. While the vast majority of ALS cases (about 90%) are considered sporadic, meaning they occur randomly with no known cause or family history, about 10% of cases are familial, linked to a genetic mutation passed down through generations. The rarity of the disease underscores the importance of recognizing its subtle early signs to ensure those affected can access specialized care promptly.
7 Early Signs of ALS That Are Often Missed
There are seven primary early signs of ALS that are often missed due to their subtlety and resemblance to other conditions: muscle weakness in a hand or leg, stumbling and tripping, difficulty with fine motor tasks, slurred or thick speech, trouble swallowing, persistent muscle cramps, and widespread muscle twitching.
These symptoms can be categorized based on their point of origin: limb-onset, bulbar-onset, or as more generalized physical signs that may appear alongside or independently of the others. To begin, understanding these signs in their specific groupings helps clarify how the disease can present differently from person to person, which is a key reason why it is so challenging to diagnose in its early stages.
1. Muscle Weakness
Muscle weakness is often one of the first signs of ALS, and it typically starts in a localized area before spreading to other parts of the body. It can begin subtly, sometimes just causing difficulty with specific tasks that were once easy. For example, a person might struggle to grip objects tightly or feel like their arm or leg is dragging while walking. This weakness occurs because ALS damages the motor neurons in the brain and spinal cord, which control voluntary muscles. As these motor neurons deteriorate, the muscles they control lose their ability to function properly.
Initially, muscle weakness may be noticed in smaller muscle groups, such as those controlling fine motor movements in the hands. You might find that it’s harder to write, button a shirt, or use a fork or spoon without dropping things. Over time, the weakness can spread to larger muscle groups, leading to difficulty with tasks like walking, standing up from a seated position, or lifting objects.
The muscles may feel heavy or stiff, making movement increasingly difficult. In some cases, the individual may even feel as though their limbs are weak and unresponsive, despite their efforts to move. This weakness is one of the hallmark symptoms of ALS and is progressive, meaning it tends to worsen as the disease advances, eventually leading to paralysis in the affected muscles.
2. Muscle Twitches (Fasciculations)
Muscle twitches, also known as fasciculations, are another common early sign of ALS. These involuntary, rapid muscle contractions can occur in various parts of the body, such as the arms, legs, or even the tongue. Fasciculations are often visible under the skin and may appear as small, twitching or fluttering movements. While muscle twitches can occur for many reasons such as stress, caffeine intake, or muscle fatigue when they occur persistently, they can signal that something more serious, like ALS, is at play.
In ALS, fasciculations occur because the motor neurons responsible for controlling muscle movements are becoming damaged. As these neurons deteriorate, the muscles they control are no longer getting proper signals, leading to the random, spontaneous contractions. In the early stages of ALS, these twitches may come and go, but as the disease progresses, they often become more frequent and widespread. They are particularly common in the arms, legs, and tongue, which are some of the first muscles affected by the disease.
While fasciculations may seem harmless at first, their persistence and the pattern of their occurrence can be a sign that ALS is causing neurological damage. This symptom often signals that the motor neurons are weakening, which makes it crucial to seek a professional diagnosis if they are accompanied by other symptoms.
3. Difficulty Speaking or Slurred Speech (Dysarthria)
As ALS affects the muscles responsible for speech, many patients begin to experience difficulty speaking or slurred speech in the early stages. This condition is known as dysarthria. The speech difficulties occur because ALS weakens the muscles involved in controlling the tongue, lips, and soft palate. As a result, speech becomes less clear, and the individual may struggle to form words properly or speak at a normal pace.
In the beginning, the speech changes may be subtle—such as the person’s voice becoming softer or more hoarse—or they might have trouble pronouncing certain words. Over time, the speech difficulties can become more pronounced, leading to slurred or slow speech. This is particularly noticeable during conversations, where the person may have trouble keeping up with others, repeating words, or needing to take frequent pauses to catch their breath.
Dysarthria in ALS is different from speech difficulties caused by other conditions like a cold or normal aging. It tends to progress over time, becoming more noticeable as the disease advances. Individuals with ALS may find it harder to communicate effectively, leading to frustration and social withdrawal. In some cases, speech therapy may be used to help individuals with ALS maintain their ability to communicate for as long as possible.
4. Difficulty Swallowing (Dysphagia)
Dysphagia, or difficulty swallowing, is a common and concerning symptom in ALS. It occurs when the muscles responsible for swallowing are weakened or paralyzed due to the loss of motor neurons. Initially, the symptoms may seem mild, such as occasional coughing or choking while eating or drinking. However, as the disease progresses, swallowing becomes more difficult and may affect both solids and liquids.
For individuals with ALS, this difficulty swallowing can be particularly dangerous because it increases the risk of aspiration—the inhalation of food or liquid into the lungs, which can lead to aspiration pneumonia. As the muscles controlling the throat and esophagus weaken, food may get stuck in the throat, or liquids may come back up, causing choking or gagging. This not only makes eating more difficult but can also lead to malnutrition and dehydration, further exacerbating the condition.
In addition to difficulty swallowing, many individuals with ALS experience a feeling of something “stuck” in their throat or a sensation of tightness while swallowing. Over time, these symptoms can lead to more severe issues, including complete inability to swallow, which can require the use of feeding tubes for nutrition. It’s important to address swallowing difficulties early, as proper management can help reduce the risks associated with this symptom.
5. Stiffness and Muscle Cramps (Spasticity)
Spasticity is a term used to describe abnormal muscle stiffness and muscle cramps, which are common in ALS patients. This stiffness results from the loss of control over the motor neurons that help regulate muscle movement. As the disease progresses, it causes the muscles to become tight and rigid, making movement more difficult. These sensations of tightness can occur in various parts of the body, most notably in the arms, legs, and neck.
People with ALS may experience muscle cramps that feel painful and are often unpredictable. These cramps can affect the hands, feet, or calves, making it uncomfortable to walk or hold objects. Spasticity can make it harder for the individual to perform everyday tasks, such as dressing, brushing their teeth, or picking up items. The muscles may feel “locked” or “frozen,” making movements jerky and awkward.
As the stiffness and cramps worsen, they can severely impact a person’s mobility, making it harder for them to walk or stand. Additionally, spasticity can cause joint pain and muscle fatigue, further reducing the quality of life. Medications, physical therapy, and stretching exercises are often used to help manage spasticity and reduce discomfort for ALS patients.
6. Changes in Gait or Walking Problems
Changes in gait or walking problems are another early indicator of ALS. This can begin as subtle changes, such as feeling unsteady or stumbling more than usual. Individuals may notice that they drag one foot while walking or have difficulty maintaining balance. As the muscles responsible for walking, such as those in the legs and feet, become weaker, coordination becomes increasingly difficult. This can lead to frequent trips or falls.
At first, walking may only seem slightly slower or less stable, but as ALS progresses, walking problems can become more severe. The individual may require the use of a walker or a cane to help with mobility. In some cases, the person might be unable to walk unaided and may need assistance or a wheelchair. Difficulty with walking is particularly dangerous as it increases the risk of falls, fractures, and other injuries. The loss of coordination and stability also contributes to overall fatigue, making it harder for individuals to engage in daily activities.
For individuals with ALS, addressing walking issues early can help with safety and mobility. Physical therapy, assistive devices, and strength training can be part of a comprehensive treatment plan to help slow the progression of gait issues.
7. Fatigue and Loss of Endurance
Fatigue is one of the most common and frustrating symptoms experienced by people with ALS. It can occur in the early stages, even before other more obvious symptoms develop. The fatigue associated with ALS is different from typical tiredness; it often feels overwhelming and persistent, regardless of how much rest a person gets. This is due to the fact that ALS affects the muscles and motor neurons, which makes even small tasks feel exhausting.
Individuals with ALS may notice that they tire more easily after completing simple tasks, like climbing stairs, lifting groceries, or even talking for an extended period of time. As the muscles weaken, the body has to work harder to perform everyday activities, which leads to increased energy expenditure. This can result in a feeling of constant exhaustion, making it difficult to engage in social, work, or recreational activities.
Additionally, ALS can affect the respiratory muscles, leading to breathing difficulties. This can further contribute to fatigue and decreased endurance. As the disease progresses, individuals may find it increasingly difficult to maintain their energy levels, often needing frequent breaks or assistance to complete tasks.
Why are These Initial Signs of ALS Frequently Attributed to Other Causes?
These initial signs of ALS are frequently attributed to other causes because they are insidious, often painless, and closely mimic a host of much more common and benign conditions. The human brain is conditioned to seek the simplest explanation for physical symptoms, and in most cases, a minor twitch, a cramp, or a moment of clumsiness is indeed just that minor and temporary.
The diagnostic challenge of ALS lies in this deceptive overlap. For example, muscle weakness and fatigue are universal experiences. They can be easily blamed on a poor night’s sleep, stress at work, a recent workout, or simply the natural process of aging. Difficulty with fine motor tasks in the hand might immediately be suspected as carpal tunnel syndrome or arthritis, especially in individuals whose jobs involve repetitive hand movements.
Tripping or foot drop can be attributed to a pinched nerve in the lower back (sciatica) or peripheral neuropathy, particularly in people with diabetes. Speech changes might be dismissed as a consequence of fatigue or dental issues, while swallowing difficulties could be attributed to acid reflux or anxiety. The absence of pain is another critical factor. Most conditions that cause significant physical impairment are associated with pain, which serves as a clear alarm signal.
ALS, in its early stages, is typically painless, which can lull both the individual and their physician into a false sense of security. Because ALS is a rare disease, it is not often the first diagnosis a primary care doctor considers. The combination of non-specific symptoms, their slow and gradual progression, and the lack of a definitive single test for ALS means that the path to diagnosis is often a process of elimination, which can take many months or even more than a year from the first onset of symptoms.
When to Seek for Medical Care About Signs of ALS
You should consult a doctor, specifically a neurologist, when you experience symptoms such as persistent and progressive muscle weakness, twitching, cramping, or changes in speech or swallowing that cannot be otherwise explained. The key differentiators for seeking medical evaluation are the terms persistent and progressive. Occasional muscle twitches, a temporary feeling of weakness after strenuous activity, or briefly slurring a word when fatigued are common and usually benign.
However, if these symptoms do not resolve and instead gradually worsen over a period of weeks or months, it is a significant red flag. For instance, if a weakness in your hand that initially made buttoning a shirt difficult has now progressed to the point where you struggle to hold a fork, medical consultation is necessary.
Next, it is crucial to understand which combinations of symptoms are particularly concerning and what type of medical professional is best equipped to diagnose and manage a potential case of ALS. Early diagnosis is vital for accessing treatments that can help manage signs of ALS and slow disease progression.
Symptoms Warrants An Immediate Consultation
A combination of progressive, asymmetric muscle weakness accompanied by muscle twitching (fasciculations) in the same or different body parts warrants an immediate neurological consultation. This clinical pairing, weakness and fasciculations, is a classic sign of motor neuron disease.
For example, if you notice that your right hand has become significantly weaker over several months, making it hard to grip objects, and you also observe persistent, involuntary muscle ripples under the skin of your arm, shoulder, or even your legs, this is a highly specific pattern that requires expert evaluation. Similarly, the onset of a foot drop (difficulty lifting the front of your foot), causing you to trip, combined with visible twitching and cramping in your calf or thigh muscles, should prompt an urgent visit to a neurologist.
Another concerning combination is the simultaneous or sequential development of bulbar and limb symptoms. For instance, experiencing slurred speech (dysarthria) that worsens over time, coupled with new-onset difficulty swallowing (dysphagia) and emerging weakness or clumsiness in a hand, is a strong indicator of a widespread neurological issue affecting both bulbar and spinal motor neurons.
Unexplained muscle wasting, or atrophy, particularly in the hands (e.g., a hollowing between the thumb and index finger) or shoulders, especially when associated with a loss of strength, is another critical sign. The presence of both upper motor neuron signs (stiffness/spasticity, exaggerated reflexes) and lower motor neuron signs (weakness, atrophy, fasciculations) is the quintessential finding in ALS, and any combination of these symptoms should be evaluated by a neurologist without delay.
Who Can Diagnoses and Treats ALS?
A neurologist is the medical specialist who diagnoses and treats Amyotrophic Lateral Sclerosis (ALS), with sub-specialists in neuromuscular diseases being the most qualified experts. A general practitioner or family doctor is often the first point of contact when signs of ALS arise, but they will refer the patient to a neurologist for a definitive diagnosis.
The diagnostic process for ALS is complex because there is no single test for the disease. Instead, it is a diagnosis of exclusion, meaning the neurologist must rule out other conditions that can mimic ALS, such as multiple sclerosis, myasthenia gravis, spinal cord tumors, or cervical spinal stenosis. This process involves a thorough neurological examination to assess reflexes, muscle strength, and sensory function, looking for the characteristic combination of upper and lower motor neuron signs.
To confirm the diagnosis and exclude other possibilities, the neurologist will order several tests. The most important of these are an electromyography (EMG) and a nerve conduction study (NCS). The EMG assesses the health of muscles and the nerve cells that control them (motor neurons) by measuring their electrical activity. In ALS, the EMG will show evidence of chronic nerve damage and active denervation.
The NCS measures how fast and how well the body’s electrical signals travel down the nerves, which helps differentiate ALS from other nerve disorders. Additional tests, such as an MRI of the brain and spinal cord, blood tests, and sometimes a lumbar puncture, are performed to rule out other conditions.
Once a diagnosis is made, ongoing care is best managed by a multidisciplinary team at a specialized ALS clinic, which includes the neurologist, physical therapists, occupational therapists, speech-language pathologists, respiratory therapists, dietitians, and social workers, all working together to manage symptoms and improve the patient’s quality of life.
How is ALS Diagnosed and Distinguished From Other Conditions?
Diagnosing Amyotrophic Lateral Sclerosis (ALS) is a complex process primarily based on a thorough clinical examination and a series of diagnostic tests aimed at ruling out other conditions with similar symptoms, a method known as differential diagnosis. Furthermore, there is no single definitive test for ALS; instead, physicians piece together evidence from multiple sources to confirm the presence of both upper and lower motor neuron degeneration while excluding other possibilities.
This meticulous process is crucial because many other neuromuscular disorders can mimic the early signs of ALS, making an accurate diagnosis essential for proper management and planning. The diagnostic journey often involves a neurologist who specializes in neuromuscular diseases and a battery of tests to build a comprehensive clinical picture.
Tests Are Used to Rule In or Rule Out ALS
The process of diagnosing ALS involves a systematic exclusion of other potential causes for a patient’s symptoms. Neurologists use a combination of clinical assessments and specialized tests to build a case for an ALS diagnosis. This journey often begins with electrodiagnostic tests, which are central to confirming motor neuron damage.
- Electromyography (EMG): This test is crucial for assessing the health of muscles and the nerve cells that control them (motor neurons). A fine needle electrode is inserted into a muscle to record its electrical activity at rest and during contraction. In ALS, an EMG can detect signs of chronic nerve damage and muscle denervation, even in muscles that appear clinically unaffected.
- Nerve Conduction Velocity (NCV) Test: Often performed alongside an EMG, the NCV test measures how fast and how well electrical signals travel along a nerve. This test helps differentiate ALS from peripheral neuropathies or conditions like demyelinating diseases, where the nerve’s protective sheath is damaged, significantly slowing signal transmission. In ALS, nerve conduction velocity is typically normal or only mildly slowed.
- Magnetic Resonance Imaging (MRI): An MRI of the brain and spinal cord is a non-invasive imaging test used to rule out other conditions that can cause similar symptoms, such as a spinal cord tumor, a herniated disk, or multiple sclerosis. It provides detailed images that can reveal structural abnormalities or evidence of inflammation that would point away from an ALS diagnosis.
- Blood and Urine Tests: Laboratory analysis of blood and urine samples can help exclude a wide range of other diseases, including thyroid disorders, vitamin deficiencies, infections like Lyme disease, and heavy metal poisoning, all of which can sometimes present with muscle weakness.
- Spinal Tap (Lumbar Puncture): In some cases, a neurologist may perform a spinal tap to analyze the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord. While there is no specific marker for ALS in the CSF, this test can help identify signs of inflammation or infection that would suggest another diagnosis, such as MS.
The Early Signs of ALS vs. Multiple Sclerosis (MS)
While both ALS and Multiple Sclerosis (MS) are progressive neurological diseases that can cause muscle weakness, their underlying pathologies and typical symptom profiles are fundamentally different. Differentiating between them is a key step in the differential diagnosis process.
- Underlying Disease Mechanism: ALS is a motor neuron disease where the nerve cells that control voluntary muscle movement degenerate and die, leading to progressive muscle weakness and atrophy. In contrast, MS is an autoimmune, demyelinating disease where the body’s immune system attacks the myelin sheath, the protective covering of nerve fibers in the central nervous system (brain and spinal cord). This damage disrupts communication between the brain and the rest of the body.
- Type of Symptoms: The most significant difference lies in the types of symptoms experienced. ALS symptoms are almost exclusively motor-related: muscle weakness, twitching, cramping, and eventually paralysis. Crucially, ALS does not affect the senses, patients do not experience numbness, tingling, or pain as a primary symptom, nor does it impact vision or bladder control in the early stages.
- Symptom Profile of MS: MS presents with a much broader range of symptoms that can include both motor and sensory issues. Common early signs of MS include numbness or tingling in the limbs or face, vision problems (such as blurred vision or pain with eye movement, known as optic neuritis), fatigue, dizziness, and problems with balance and coordination. Bladder and bowel issues are also common. The pattern of MS symptoms often involves relapses (periods of new or worsening symptoms) and remissions (periods of recovery), a pattern not seen in the steady, progressive decline of ALS.
ALS Symptoms vs. Parkinson’s Symptoms?
ALS and Parkinson’s Disease both affect motor function, but they do so in distinctly different ways due to their unique pathological processes. ALS is a disease of the motor neurons, while Parkinson’s Disease results from the loss of dopamine-producing cells in a specific area of the brain called the substantia nigra.
- Core Motor Symptoms: The defining features of each condition are starkly different. ALS is characterized by progressive muscle weakness, muscle atrophy (wasting), and fasciculations (visible muscle twitches). This leads to a loss of ability to initiate and control voluntary movements. In contrast, Parkinson’s Disease is defined by a different set of primary motor symptoms:
– Resting Tremor: A characteristic shaking that occurs when the muscles are at rest, often starting in one hand (“pill-rolling” tremor). This tremor typically diminishes during purposeful movement.
– Bradykinesia: A pronounced slowness of movement that can make everyday tasks difficult and time-consuming.
– Rigidity: Stiffness in the limbs, neck, or trunk, which can cause muscle aches and limit the range of motion.
– Postural Instability: Impaired balance and coordination, which develops in later stages and increases the risk of falls.
- Nature of Muscle Impairment: In ALS, the primary problem is weakness; the muscles lose their strength because the nerves supplying them are dying. In Parkinson’s, muscle strength is generally preserved in the early stages. The difficulty lies not in a lack of power but in the brain’s ability to control and initiate smooth, coordinated movements. While ALS leads to paralysis, Parkinson’s leads to a poverty of movement, where actions become slow, stiff, and shaky. Furthermore, cognitive changes, such as problems with executive function, are more common in Parkinson’s than in the early stages of ALS.
Treatment for ALS
Currently, there is no cure for ALS, and no treatment can reverse the damage already done to motor neurons. However, the landscape of ALS management has evolved significantly, and several therapeutic options exist to slow disease progression, manage symptoms, and improve the overall quality of life for patients.
The approach to treatment is multidisciplinary, involving a team of healthcare professionals who address the various physical, emotional, and practical challenges posed by the disease. Medications approved by the U.S. Food and Drug Administration (FDA) form a core part of this strategy. For instance, drugs like riluzole have been shown to modestly slow the progression of ALS, potentially extending survival by several months. Other medications, such as edaravone, may help slow the decline in daily functioning for some patients.
Beyond disease-modifying drugs, comprehensive symptom management is essential for maintaining comfort and independence for as long as possible. A coordinated care approach addresses the multifaceted nature of ALS:
- Therapeutic Support: Physical therapy helps maintain muscle strength and mobility, occupational therapy provides adaptive equipment and strategies for daily living, and speech therapy assists with communication and swallowing difficulties.
- Respiratory Care: As the muscles that control breathing weaken, non-invasive ventilation (NIV) using devices like BiPAP machines can significantly improve respiratory function and quality of life. In advanced stages, mechanical ventilation may be necessary.
- Nutritional Support: A nutritionist can help manage swallowing difficulties (dysphagia) and ensure adequate caloric intake to prevent weight loss and muscle wasting. In many cases, a feeding tube (percutaneous endoscopic gastrostomy or PEG tube) becomes necessary to maintain nutrition and hydration. Clinical trials also remain a vital avenue, offering patients access to promising new therapies and contributing to the global effort to find a cure.
