Phonagnosia: Phonagnosia is associated with the inability to recognize any familiar voices. In these cases, speech stimuli can be heard and even understood but the association of the speech to a certain voice is lost. This can be due to "abnormal processing of complex vocal properties (timbre, articulation, and prosody—elements that distinguish an individual voice". There is no known treatment; however, there is a case report of an epileptic woman who began to experience phonagnosia along with other impairments. Her EEG and MRI results showed "a right cortical parietal T2-hyperintense lesion without gadolinium enhancement and with discrete impairment of water molecule diffusion". So although no treatment has been discovered, phonagnosia can be correlated to postictal parietal cortical dysfunction.
