One year of daily Daybue (trofinetide) treatment led to improvements in behaviors such as nonverbal communication, alertness, and social interaction and connectedness among children and adults with Rett syndrome. That’s according to published interim data from Acadia Pharmaceuticals‘ Phase 4 LOTUS study that assessed the safety and…
Girls with Rett syndrome often face challenges when it comes to eating and drinking, according to a 20-year analysis. Due to limited hand function and difficulties with chewing and swallowing, many are unable to feed themselves or handle a wide variety of foods and liquids. As these…
Reduced production of orexin and its receptors is associated with problems in sleep-wake cycles in a mouse model of Rett syndrome (RTT), a study suggests. Orexin is a signaling molecule that regulates sleep and wakefulness in the brain. While circadian rhythms that regulate the sleep-wake cycle were generally unaffected in…
Vorinostat, an approved lymphoma treatment sold as Zolinza, was found to ease both neurological and non-neurological symptoms in a mouse model of Rett syndrome in a new study. When an oral formulation of vorinostat was administered after symptom onset, the drug was even more effective than Daybue (trofinetide),…
Cannabidivarin (CBDV), a non-psychoactive compound found in cannabis, preserves cognitive function and improves motor coordination in a female mouse model of Rett syndrome, a study suggests. “These findings provide new insights into the role of CBDV in [Rett] and support for future research, highlighting its potential as a ……
A lack of awareness or misconceptions in the medical community about Rett syndrome occurring in boys and men commonly leads to misdiagnoses or diagnostic delays, according to a new study. “Diagnostic providers must increase their awareness of males with [Rett] and be prepared to deliver the diagnosis with empathy…
Changes in auditory event-related potentials, or AEPs, the brain’s electrical activity in response to sound, may serve as a non-invasive biomarker to assess treatment response in people with Rett syndrome, a study suggested. Depressed AEPs, as measured by electroencephalography (EEG), which detects the brain’s electrical activity, were normalized when…
Girls with Rett syndrome have significantly smaller brain volumes across all its regions, regardless of their age, a MRI study shows. Reductions in the size of certain brain regions were tied to the clinical severity of Rett patients, particularly in gross motor function, such as sitting and walking. Still,…
Bone mineral density, an indicator of bone strength, is significantly lower in girls and young women with Rett syndrome compared with healthy girls and women of the same age, a study shows. Reduced bone mineral density was tied to small body size, impaired mobility, and the use of the…
NLX-101 improves breathing and cognitive function in a female mouse model of Rett syndrome, a study found. The potential therapy activates the receptors that bind serotonin, a signaling molecule found at low levels in the brains of Rett patients. “This work provides compelling evidence of the therapeutic potential of…
