There are many terms—some technical and some not—that are used widely in the ALS community. Below are many of the words and terms you will encounter when reading about ALS or talking with healthcare professionals.

AAC (augmentative and alternative communication) – any form of communication that does not involve speaking—such as writing, gesturing, or using speech-generating devices

ADLs (activities of daily living) – the basic things you do every day, like bathing, eating, going to the toilet, and brushing your teeth

advance directives – written documents that state your wishes regarding the type of medical treatment you would—or wouldn’t—want in the event of an emergency

ALS (amyotrophic lateral sclerosis) – a chronic neuromuscular disease with no known cure that attacks motor neurons, which results in the weakening and atrophy of muscles

ALS advocate – a person who takes action to raise awareness about ALS and improve laws that affect the ALS community

ALS Certified Treatment Centers – medical institutions that are certified and funded by The ALS Association to provide ALS clinics for patients

ALS clinics – treatment centers where multidisciplinary medical teams meet with ALS patients to monitor progress and make recommendations

aspiration – when foods, liquids, or saliva inadvertently go into the lungs instead of the stomach

BiPAP (Bilevel Positive Airway Pressure) – a small breathing machine that delivers pressurized air through a facemask to assist with inhaling and exhaling

bulbar onset – a type of ALS that begins by affecting speech, swallowing, and facial muscles

CALS (caregiver of a person with ALS) – a widely used term in the ALS community that refers to the primary caregiver of a person with ALS—usually a spouse or family member

caregiver – a loved one (or paid professional) who helps with activities of daily living and more

dietitian – a healthcare professional who can develop strategies to help you receive proper nutrition

DME (durable medical equipment) – equipment that Medicare and insurance companies consider medically necessary, and will therefore cover

DNR (do-not-resuscitate order) – a legal order written in advance that instructs health care professionals not to perform CPR or other other life-saving techniques in the event that you stop breathing or your heart stops beating

dysarthria – slurred or slow speech due to weakened or affected muscles

dysphagia – difficulty swallowing

EMG (electromyography) – a series of tests that help neurologists diagnose patients with muscle weakness

familial ALS – a genetically inherited form of ALS that runs in the family and affects 5-10% of all ALS patients

fasciculations – muscle twitching

FTD (frontotemporal dementia) – nerve cell damage to the brain that can affect personality, behavior, and language

invasive ventilation – long-term mechanical breathing support through a tube that is inserted through the mouth, nose, or windpipe

motor neuron – a nerve cell that helps transmit messages from the central nervous system to muscles

nerve conduction – a test for nerve damage

neurologist – a doctor who specializes in diagnosing and treating diseases of the nervous system, including ALS

onset – the first signs or symptoms of an illness prior to diagnosis

OT (occupational therapist) – a healthcare professional who can help you achieve more independence with activities of daily living through support, training, adaptive equipment, and modifications to your environment

PALS (person diagnosed with ALS) – a widely used term in the ALS community that refers to a person diagnosed with ALS

PEG (percutaneous endoscopic gastrostomy) – a procedure that helps people with swallowing difficulties receive liquid, nutrition, and medication through a feeding tube that is inserted into the stomach

PLS (primary lateral sclerosis) – a motor neuron disease closely related to ALS that only affects the upper motor neurons and progresses more slowly than ALS and PMA

PMA (progressive muscular atrophy) – a motor neuron disease closely related to ALS that only affects the lower motor neurons and progresses more slowly

pseudobulbar palsy – a motor neuron disease closely related to ALS that primarily affects the ability to speak, swallow, and chew

PT (physical therapist) – a healthcare professional who can help improve your mobility, strength, balance, and flexibility through techniques such as exercises, stretching, and massage

Radicava (edaravone) – after a promising clinical trial in Japan, it is the second drug approved by the FDA to treat ALS and will become available in the United States in August 2017

respite care – care provided by loved ones, volunteers, or professionals either at home or in a facility with the purpose of providing a break for primary caregivers

Rilutek (riluzole) – the first FDA-approved drug for ALS that may prolong life for about 90 days; it does not reverse nerve damage or muscle weakness

ROM (range of motion) – measurement of movement and flexibility around a joint

SGD (speech generating device) – an electronic device that speaks the messages you create through typing or gazing at letters, words, phrases, or images

sialorrhea – excessive drooling

SLP (speech language pathologist) – a health care professional who can help you communicate through various strategies, including the use of augmentative and alternative communication devices
