Pediatric neurologists’ expectations in terms of treatment benefits are decidedly higher for infants and toddlers with spinal muscular atrophy (SMA) types 1 and 2 than for adolescent patients, a study in Spain shows. Notably, neurologists with low aversion to ambiguity and low expectation of treatment benefits were more likely…

The total medical costs associated with spinal muscular atrophy (SMA) are lower for patients diagnosed at birth via newborn screening, compared with those diagnosed after they start showing symptoms of the disease, a new study has found. These findings “demonstrate clearly that as long as the decision to reimburse…
The newborn screening program at Cadham Provincial Laboratory in Manitoba, Canada, is expanding to include spinal muscular atrophy (SMA), according to an announcement from Audrey Gordon, the province’s health minister. “Early diagnosis is the key to improving outcomes for babies born with metabolic, endocrine or genetic disorders such as…
A new modeling study predicts that higher doses of Spinraza (nusinersen) may improve its effectiveness compared with the approved 12 mg dose. The study used data from two clinical trials that evaluated the disease-modifying therapy in infants with spinal muscular atrophy (SMA). “The [pharmalogical] model indicates that the…
Among adults with spinal muscular atrophy (SMA) type 3, those with greater motor impairment tend to score better on some cognitive measures, but worse on others, a new study reports. Among those with SMA, “patients with greater motor difficulties had lower performance in attention, but higher performance in measures…
Combining two clinical assessment tools helped recognize early neurological signs in infants with spinal muscular atrophy (SMA) who were identified through a newborn screening program, a study suggested. Even in the absence of obvious clinical signs, infants typically defined as presymptomatic may have minimal signs, such as poor muscle…
Infants with spinal muscular atrophy (SMA) who are being screened for Zolgensma may present with maternal antibodies against the therapy’s viral carrier — making them ineligible for the therapy — until the age of 8 months, a small study shows. This means that an infant first testing positive for…
The U.S. Food and Drug Administration (FDA) has extended its approval of Evrysdi (risdiplam) to treat babies with spinal muscular atrophy (SMA) who are younger than 2 months old. Evrysdi, an oral therapy that works by increasing the levels of the survival motor neuron (SMN) protein that is missing in…
MicroRNAs isolated from people with spinal muscular atrophy (SMA) types 2 and 3 before treatment predicted eventual responses to Spinraza (nusinersen) therapy, a study suggested. The study, “Muscle microRNAs in the cerebrospinal fluid predict clinical response to nusinersen therapy in type II and type III…
Development of an exoskeleton suit to help those living with progressive neuromuscular conditions that affect their upper-body movement will advance due to a £1.25 million (about $1.5 million) grant from the People’s Postcard Lottery in the United Kingdom. The “SMART Suit,” which targets people with disabilities such as…
