Anterior corpus callosum lesions may result in akinetic mutism or anomic aphasia. Selective mutism usually co-exists with shyness or social anxiety. By day 2 (D2), many patients experienced confusion, agitation, dysarthria, mutism and incontinence. Selective mutism usually co-exists with social anxiety disorder. The results indicated behavioral inhibition does indeed predispose selective mutism. Cho had previously been diagnosed with selective mutism and severe depression. Many children with selective mutism have some auditory processing difficulties. Furthermore, SSRIs in particular have been used to treat selective mutism. Most children with selective mutism are hypothesized to have an inherited predisposition to anxiety. Mesencephalic akinetic mutism is clinically categorized as somnolent or apathetic akinetic mutism. This indicates that fluoxetine is an SSRI that is indeed helpful in treating selective mutism. Children may not speak due to suffering from selective mutism. Some children with selective mutism may have trouble processing sensory information. Such lesions result in akinesia, mutism, apathy, and indifference to painful stimuli. This is indicative of the positive correlation between behavioral inhibition and selective mutism.
