Trial Summary

What is the purpose of this trial?

Individuals with Fragile X Syndrome show differences in how they understand and learn language from infancy. They frequently have lifelong delays in speech and language as well. In addition, they experience other auditory symptoms, including being very sensitive to certain sounds as well as being more sensitive than others to loud sounds. The underlying brain activity for sound perception and speech learning in Fragile X is not well understood, especially in the infant and toddler years. This study uses behavioral assessment of speech and language abilities, neuroimaging, and hearing tests to understand how speech and hearing are different in children with Fragile X Syndrome.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Speech discrimination, Speech Therapy, Auditory Training for Fragile X Syndrome?

Research indicates that individuals with Fragile X Syndrome have difficulties with auditory processing and speech sound processing, which can impact language development. Speech therapy and auditory training may help improve these areas by targeting the specific auditory and speech challenges identified in studies, such as impaired phonological processing and abnormal neural responses to sounds.12345

Is speech discrimination therapy safe for humans?

The research articles provided do not contain specific safety data for speech discrimination therapy or related treatments like speech therapy or auditory training in humans.46789

How does the treatment Speech Discrimination differ from other treatments for Fragile X Syndrome?

Speech Discrimination therapy focuses on improving the ability to distinguish and understand speech sounds, which is particularly important for individuals with Fragile X Syndrome who often have difficulties with language development and auditory processing. This approach is unique because it targets the specific auditory processing challenges associated with the syndrome, unlike other treatments that may not address these specific speech and language issues.123510

I can sit up on my own without help.

Exclusion Criteria

Not born prior to 32 weeks gestation (for typical development group and Fragile X group)
I haven't had a seizure in the last 6 months.

Findings from Research

Phonological accuracy and intelligibility in connected speech of boys with fragile X syndrome or Down syndrome.Barnes, E., Roberts, J., Long, SH., et al.[2021]
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]
This study reveals that Fmr1 knockout rats, a model for fragile X syndrome, show significant impairments in the cortical representation of speech sounds, despite being able to discriminate speech normally, indicating a disconnect between perception and processing.
The greatest deficits were found in the ventral auditory field, which is linked to emotional regulation, suggesting that these processing issues may contribute to emotional challenges in individuals with fragile X syndrome.
Degraded speech sound processing in a rat model of fragile X syndrome.Engineer, CT., Centanni, TM., Im, KW., et al.[2021]
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.

Speech-language pathologists observed that young males with fragile X syndrome (FXS) often have unique communication difficulties, including a preference for visually based and experiential learning, which necessitates individualized and syndrome-specific interventions.
Interventions should address specific challenges such as limited attention spans, sensory sensitivities, and anxiety, focusing on tailored speech and language goals that enhance verbal communication, listening skills, and social interactions.

A study involving 23 young males with Fragile X syndrome (FXS) found that their auditory brainstem responses (ABRs) were within normal limits, indicating typical auditory function despite the syndrome's associated developmental delays.
When compared to typically developing males matched for both developmental and chronological age, males with FXS showed no significant differences in hearing sensitivity or auditory pathway integrity, suggesting that FXS does not inherently affect auditory brainstem function.
Auditory brainstem responses in young males with Fragile X syndrome.Roberts, J., Hennon, EA., Anderson, K., et al.[2007]
In a study of 62 males with Fragile X syndrome, those with a mosaic pattern of premutation and full mutation alleles exhibited lower levels of irritability and inappropriate speech compared to those with only full mutation alleles and complete loss of FMR1 mRNA.
Higher levels of FMR1 mRNA were linked to increased irritability and lower quality of life scores, particularly in males with incomplete silencing of the FMR1 gene, suggesting that FMR1 mRNA levels could be an important factor in understanding behavioral outcomes in Fragile X syndrome.
FMR1 mRNA from full mutation alleles is associated with ABC-CFX scores in males with fragile X syndrome.Baker, EK., Arpone, M., Kraan, C., et al.[2021]
