Prazosin use in a patient with rare Neurobeachin gene deletion shows improvement in paranoid behavior: a case report.

BackgroundDisruption of the Neurobeachin gene is a rare genetic mutation that has been implicated in the development of autism and enhanced long-term potentiation of the hippocampal CA1 region, causing a heightened conditioned fear response and impaired fear extinction. Prazosin, an alpha-1 receptor antagonist, has been used in patients with posttraumatic stress disorder to mitigate the increased alpha-1 activity involved in fear and startle responses. Here we report a case of a patient with a rare Neurobeachin gene deletion, who demonstrated marked and sustained improvement in paranoid behavior within days of prazosin initiation.Case presentationThe patient is a 27-year-old White male with autism spectrum disorder, obsessive-compulsive disorder, and schizophrenia, with a chromosome 13q12 deletion including deletion of the Neurobeachin gene, who presented to the emergency department due to worsening functional status and profound weight loss as a result of only eating prepackaged foods. He had not showered or changed clothes in several months prior to presentation. He was hospitalized in the inpatient psychiatric unit for 2 months before prazosin was initiated. During that time, he demonstrated paranoia as evidenced by heightened sensitivity to doors opening, guarded interactions, and limited communication with providers and other patients. He also exhibited poor grooming habits, with aversion to showering, shaving, and changing clothes. Since initiating prazosin, he has demonstrated a brighter affect, initiates and maintains conversations, showers and changes clothes on a regular basis, and eats a variety of foods. At the time of this report, the patient was discharged to live in an apartment with a caregiver after a 7-month inpatient hospitalization.ConclusionsLow-dose prazosin shows rapid and sustained improvement in paranoid behavior in a patient with a rare Neurobeachin gene deletion. Prazosin has a relatively favorable side effect profile with once-daily dosing and low cost. Prazosin may provide clinical improvement in patients with Neurobeachin gene deletions due to its theoretical attenuation in fear response through alpha-1 antagonism

Clinical response of clozapine as a treatment for delirious mania

Delirious mania is an understudied psychiatric disorder with a mortality rate as high as 75%. Previous case studies suggest that electroconvulsive therapy (ECT) may be an effective treatment for delirious mania, though this procedure may not always be a viable option. We describe the case of a 20-year old patient, with no previous psychiatric history, who developed delirious mania over the course of four months. ECT was not a viable option for this patient due to his religious beliefs, so alternative treatment modalities were explored. After failing trials of risperidone and olanzapine, significant improvements in symptoms were exhibited with a trial of clozapine. We propose that clozapine may be an effective option in cases of delirious mania, when ECT is not a viable option. Additional research is still necessary to understand the pathology of this condition and potential treatment modalities
