Warning Signs Of Carpenter Syndrome

Intellectual Disability

Intellectual disability is a less common manifestation of Carpenter syndrome, as many patients have normal intelligence levels or mildly impaired intelligence, though a few mechanisms contribute to this symptom. The patient may experience impaired conduction of sound from the middle to inner ear or conductive hearing loss that contributes to their intellectual disability. The nerves responsible for transmitting impulses with sound information to the patient's brain may have abnormalities that cause sensorineural hearing loss. Both sensorineural hearing loss and conductive hearing loss can contribute to intellectual impairment independent of each other or concurrently. The damage inflicted on a Carpenter syndrome patient's brain tissues due to abnormalities caused by the premature fusion of their skull bones can also contribute to their intellectual disability.
