Palinacousis as Discontinuation Symptom after Antipsychotic Treatment in a Patient with First-Episode Schizophrenia

Palinacousis

“…Lastly, in a patient with newly diagnosed schizophrenia the withdrawal of risperdone triggered palinacousis as well as music hallucinations (Wustmann et al, 2010). This patient described hearing contents of conversations after they had ended.…”

“…In 2 (8%) documented cases the perseverated stimulus was heard ipsilateral to the lesion (Jacobs et al, 1973;Fukutake and Hattori, 1998). In the remaining cases no lesion was found, the patients could not lateralize/localize the sound, or it seemed to perseverate from the initial stimulus location (Jacobs et al, 1971;Bekeny and Peter, 1972;Malone and Leiman, 1983;Masson et al, 1993;Freudenreich and McEvoy, 1996;Terao and Matsunaga, 1999;DiDio et al, 2007;Kim et al, 2007;Wustmann et al, 2010;Bega et al, 2014). DiDio et al (2007) described a 49-year-old woman with a history of depression, anxiety, and known left parietal cavernous angioma.…”

“…In fact, up to 75% of schizophrenic patients experience auditory hallucinations (Nayani and David, 1996). There have been 4 cases described in the literature where patients with schizophrenia concomitantly suffered from palinacousis (Malone and Leiman, 1983;Freudenreich and McEvoy, 1996;Prueter et al, 2002;Wustmann et al, 2010). Both palinacousis and auditory hallucinations are false perceptions of sound.…”

“…These include vascular malformations, intracerebral hemorrhages, primary brain tumors, including meningiomas, astrocytomas, and glioblastomas, metastatic tumors, stroke, traumatic brain injury, and meningioencephalitis caused by cystercercosis (Bekeny and Peter, 1972;Jacobs et al, 1973;Patterson et al, 1988;Masson et al, 1993;Freudenreich and McEvoy, 1996;Fukutake and Hattori, 1998;DiDio et al, 2007;Kim et al, 2007;Mohamed et al, 2012;Bega et al, 2014). Additionally, there are a number of cases where no lesion was identified yet palinacousis was attributed to alcohol withdrawal (Wustmann and Gutmann, 2007), seizures themselves, or antipsychotic medication withdrawal (Wustmann et al, 2010). Additionally, there are a number of cases where no lesion was identified yet palinacousis was attributed to alcohol withdrawal (Wustmann and Gutmann, 2007), seizures themselves, or antipsychotic medication withdrawal (Wustmann et al, 2010).…”

“…There are 2 cases of palinacousis occurring in conjunction with music hallucinations (Terao and Matsunaga, 1999;Wustmann et al, 2010). Music hallucinations are characterized by perceiving music without an external source.…”
