Orofacial Apraxia

Orofacial apraxia is having a difficulty or inability in performing voluntary movements with the muscles of the larynx, pharynx, tongue, lips, cheeks, and face, although the automatic (non-voluntary) movements of the same muscles aren't effected. Apraxia itself is a motor disorder that is caused by damage to the brain, specifically the posterior parietal cortex, where the individual has a distinct difficulty with motor planning to be able to perform tasks or movements such as smiling or frowning when asked to do so.
