Sensory issues in adult autism are often an important autism indicator that many adults with undiagnosed autism experience. These sensory sensitivity traits can be subtle, easily overlooked, or mistaken for other conditions, which can delay a proper diagnosis. Recognising sensory challenges is crucial, as they can significantly impact daily life, including social interactions and work performance, for those who haven’t yet identified their condition.

In adults, undiagnosed traits of autism often present differently from how they do in children, leading to a delay in recognising autism. Many individuals develop coping mechanisms to manage their discomfort, masking the underlying issues. Without a formal diagnosis, these adults may struggle to understand why they feel overwhelmed in certain situations, which can result in unnecessary stress.

Common Sensory Sensitivities in Adults with Autism

Here are some key sensory-related issues that may signal undiagnosed autism:

Sensitivity to Sound:

Adults with autism may experience discomfort or stress in noisy environments, such as crowded places or loud offices. This heightened sensitivity can be overwhelming and lead to social withdrawal. Support and coping strategies can help manage this sensitivity, improving comfort in such environments.

Discomfort with Textures:

Certain fabrics, food textures, or even surfaces may cause significant discomfort to adults with autism. This can lead to avoidance of behaviours or even anxiety. Gradual exposure through sensory integration therapy can help desensitise these reactions.

Over-Sensitivity to Light:

Bright or flickering lights can be particularly challenging for adults with autism, leading to irritability or discomfort. Managing this sensitivity may involve environmental adjustments and therapeutic techniques to reduce stress.
