Evoked potentials can help in diagnosing both hearing loss and autism. It measures the electrical activity of the brain in response to sensory stimuli, such as sound or visual cues. In the case of hearing loss, the test determines whether the brain's response to sound stimuli is within normal limits. In the case of autism, it can detect abnormalities in sensory processing. Electroencephalography (EEG) can also aid in diagnosing autism by measuring brain wave activity, but it is not as specific in detecting hearing loss. CT and fMRI are imaging technologies that are helpful in diagnosing structural abnormalities in the brain but are not as useful in detecting hearing loss or autism specifically.
