Objective:
To describe cognitive and speech-language functioning of patients with ataxia-telangiectasia (A-T) in relation to their deteriorating (oculo)motor function.
Design:
Observational case series.
Methods:
Cognitive functioning, language, speech and oral-motor functioning were examined in eight individuals with A-T (six boys, two girls), taking into account the confounding effects of motor functioning on test performance.
Results:
All patients, except the youngest one, suffered from mild-to-moderate/severe intellectual impairment. Compared to developmental age, patients showed cognitive deficits in attention, (non)verbal memory and verbal fluency. Furthermore, dysarthria and weak oral-motor performance was found. Language was one of the patients' assets.
Conclusion:
In contrast to the severe deterioration of motor functioning in A-T, cognitive and language functioning appeared to level off with a typical profile of neuropsychological strengths and weaknesses. Based on our experiences with A-T, suggestions are made to determine a valid assessment of the cognitive and speech-language manifestations.

Autism Spectrum Disorder
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
