Over recent years, research on sensory sensitivity in autism has gained momentum, exploring neural mechanisms, clinical interventions and phenotypic variation. While still an emerging field, several promising lines of inquiry are shaping our understanding of how hypersensitivity arises and how it might be managed.

Current themes and directions in sensory research

Below are key areas under investigation within research on sensory sensitivity in autism:

Neural and Genetic Mechanisms

Recent work has focused on genetic mutations such as SCN2A and their influence on sensory reflex circuits. Scientists found that mutations affecting ion flow in neurons may alter basic sensory thresholds, contributing to oversensitivity to light, sound or touch. Other studies use computational models to simulate sensory processing research, exploring how hyperconnectivity or altered gain control in brain networks might amplify sensory experiences in autism.

Quantitative Sensory Testing and Psychophysiology

Some researchers are using quantitative sensory testing (QST) to assess pain, tactile or temperature thresholds in autistic individuals. For example, a recent study combining QST with EEG aimed to link subjective sensory reactivity to measurable neural responses. This approach seeks to go beyond questionnaire data and observe sensory processing more directly.

Phenotypic Correlations and Broader Trait Studies

Other efforts examine how sensory hypersensitivity correlates with broader autistic traits. A new study with children showed that higher sensory scores predicted difficulties in attention switching and communication domains. These clinical studies help clarify how sensory sensitivity interacts with autism’s social and cognitive features.

While the evidence base is still developing, these research pathways are helping to uncover the biology, diversity and therapeutic potential of sensory sensitivity in autism.
