Higher levels of the glial fibrillary acidic protein (GFAP) in the fluid around the brain and spinal cord are associated with poorer motor function among people with spinal muscular atrophy (SMA), a new study reports. These results indicate that cells called astrocytes are more active in advanced SMA, according…

In the first year of a newborn screening program for spinal muscular atrophy (SMA) in Japan, more than 10,000 babies were screened and one tested positive for the disease, according to a new study. The baby with SMA was able to receive the gene therapy Zolgensma (onasemnogene abeparvovec-xioi)…
Compared to what would be expected without treatment, the approved oral therapy Evrysdi (risdiplam) led to marked benefits in survival and motor outcomes for babies with spinal muscular atrophy (SMA) type 1, according to a comparison of clinical trial data. “Untreated infants with Type 1 SMA … reached…
Moxifloxacin, an antibiotic with a well-established safety profile, boosted production of the SMN protein in cellular models of spinal muscular atrophy (SMA) and it extended the lifespan and improved motor function in mice with the disease, a new study reports. “Preclinical data from patient-derived MNs [motor neurons] and a…
Rehabilitation sessions using a robotic suit called ATLAS 2030 improved joint strength and mobility in three boys with spinal muscular atrophy (SMA) type 2, according to data from a clinical trial. While wearing the device, the boys, who could not walk independently, were able to complete tasks involving standing,…
Initiating a disease-modifying therapy (DMT) before the onset of symptoms and at the earliest time possible results in the best outcomes in infants with spinal muscular atrophy (SMA), with most achieving otherwise unachievable motor milestones and within the normal age range. This is particularly crucial for infants likely…
For most of his life, Jose Flores avoided interacting with the spinal muscular atrophy (SMA) community because he felt out of touch with it. An SMA type 4 patient, Flores didn’t need a wheelchair until he was 22, and found it difficult emotionally to see children who weren’t…
Muscle fasciculations, or twitches, in adolescents and adults with later onset forms of spinal muscle atrophy (SMA) were detected best with a muscle ultrasound, a study concluded. Muscle ultrasound combined with a physical examination is useful for screening adolescents and adults with weakness in muscles closest to the center…
Among adults with spinal muscular atrophy (SMA) being treated with Spinraza (nusinersen), a decrease in levels of the inflammatory protein YKL-40 in the fluid around the brain is associated with improvements in arm and hand function, according to a new study. “We conclude that YKL-40 in CSF [cerebrospinal…
The RNA-binding protein Mid1 increases levels of the mutated androgen receptor (AR) that drives nerve cell degeneration in spinal and bulbar muscular atrophy (SBMA), a new study shows. Since Mid1 is expressed mainly in lower motor neurons, the nerve cells mainly affected in SBMA, the study’s researchers proposed that…
