What data supports the effectiveness of the treatment Alpha Auditory Entrainment for Fragile X Syndrome?

Research shows that individuals with Fragile X Syndrome have altered brain activity, including changes in alpha and gamma oscillations, which are linked to sensory hypersensitivity and intellectual disability. Alpha Auditory Entrainment may help by targeting these brain wave patterns, potentially improving sensory processing and reducing hyper-excitability.12345

How is Alpha Auditory Entrainment treatment different from other treatments for Fragile X Syndrome?

Alpha Auditory Entrainment is unique because it targets the brain's alpha waves, which are often disrupted in Fragile X Syndrome, to help manage symptoms like sensory hypersensitivity and intellectual disability. This approach focuses on modulating brain activity through sound, rather than using medication, making it a novel non-drug therapy for this condition.23456

What is the purpose of this trial?

Fragile X Syndrome (FXS) is a complex neurodevelopmental disorder caused by a mutation on the X chromosome. Scientists have investigated FXS extensively in both humans and animals. Thus far, phenotypic rescue in animal models has not resulted in treatment breakthroughs in humans, though some important discoveries have been made. Research has shown that individuals with FXS process sounds differently than those in the typical population, and they also show baseline differences in brain activity, including high gamma activity, increased theta activity, and decreased alpha activity. The investigators' central hypothesis is that these alterations in brain activity (specifically alpha and gamma activity) impair the brain's ability to process new information, thereby impeding cognitive functioning and increasing sensory sensitivity. The investigators propose that auditory entrainment, a technique that involves playing special sounds through headphones, will normalize brain activity in individuals with FXS and lead to increased cognitive function and decreased sensory hypersensitivity.

Findings from Research

In a study of 933 individuals with fragile X syndrome (FXS), sensory symptoms (SS) and signs of hyperarousal (HA) were more prevalent in males, with 87% of males experiencing SS compared to 68% of females, indicating a gender difference in symptom expression.
The presence of strong sensory responses was linked to more behavioral problems and limited participation in daily activities, highlighting the need for further research on how these symptoms affect individuals with FXS and their families.
Sensory Symptoms and Signs of Hyperarousal in Individuals with Fragile X Syndrome: Findings from the FORWARD Registry and Database Multisite Study.Lachiewicz, AM., Stackhouse, TM., Burgess, K., et al.[2023]
Individuals with fragile X syndrome (FXS) exhibit distinct auditory processing abnormalities, including larger N1 and P2 amplitudes and abnormal modulation of these responses, which may impact language development and pattern recognition.
Despite showing a normal developmental trajectory for most auditory measures, participants with FXS demonstrate age-independent and gender-dependent challenges in processing novel stimuli, suggesting potential biomarkers for clinical trials.
Development of Neural Response to Novel Sounds in Fragile X Syndrome: Potential Biomarkers.Ethridge, L., Thaliath, A., Kraff, J., et al.[2022]
The study found that adolescents and adults with fragile X syndrome (FXS) exhibited decreased gamma band phase-locking in their auditory cortex, indicating altered neural entrainment compared to healthy controls.
These neural abnormalities were linked to heightened sensory sensitivities and social communication deficits, suggesting that targeting the functionality of fast-spiking interneurons could be a potential therapeutic strategy for FXS.
