SPINAL MUSCULAR ATROPHY

IN ADULTS

SMA is a progressive disease classified into several types based on the age of onset and the degree of motor function achieved by the affected individual. Adult-onset SMA may have milder symptoms, which could result in a delay in diagnosis.1,2 In this section you can learn about identifying SMA symptoms in adults and where to access resources that could support you in your daily life with SMA.

The characters shown are real patients and the required consent to use their stories has been obtained from the patients and families. Photographs are for illustrative purposes only.

SMA IN ADULTS

SIGNS AND SYMPTOMS

Have you experienced muscle weakness? Less severe forms of SMA can emerge and be diagnosed in adulthood.3,4 Compared to childhood SMA, adult SMA may have milder symptoms, but is still progressive. Compared to SMA in childhood, the course of SMA in adults can be more insidious and difficult to recognise.2

SMA IN ADULTS

HOW TO GET DIAGNOSED

It is often difficult to diagnose SMA based on symptoms alone. Therefore, when a specialist suspects that you might have SMA they will order a genetic blood test that could confirm or rule out their preliminary diagnosis.5

SMA CARE IN ADULTS

For people living with SMA, health outcomes correlate with patient care and management of the disease. A range of care options and the careful management of SMA can result in improved quality of life, compared to being left untreated.5,6

SMA IN ADULTS

DISEASE IMPACT AND TREATMENT

Spinal muscular atrophy (SMA) is a genetic disease that affects the nervous system and worsens over time.6,7 

SMA IN ADULTS

ADULTS LIVING WITH SMA

Once thought to be primarily a childhood disease, SMA can be diagnosed in adolescents, young adults and even those beyond 21 years of age.7

During the past decade, there has been a marked improvement in the ability of clinicians to manage the multiple respiratory, nutritional, orthopedic, rehabilitative, emotional, and social issues in most SMA patients.6

About Together in SMA

At Biogen, we are committed to supporting those with spinal muscular atrophy and their care team. Our hope for Together in SMA is that, by providing information, we can help you to get the most up-to-date care, and to help guide conversations with your doctors.

Here you'll find information about spinal muscular atrophy and its symptoms, insights into care options, and perspectives from people living with SMA, experienced caregivers and healthcare professionals on topics ranging from nutrition to adaptive equipment.

Biogen is working with a number of organisations dedicated to individuals living with SMA.
