EV1008 E-PosterConsultation-Liaison PsychiatryCase Report # Misdiagnosed hydrocephalus treated as an anxiety disorder: a case report on the utility of EEG in psychiatry MISDIAGNOSED HYDROCEPHALUS TREATED AS ANXIETY DISORDER- CASE REPORT OF USEFULNESS OF EEG IN PSYCHIATRY Presenter: Nensi Manusheva Country: North Macedonia Institution: University Psychiatry Clinic In a patient followed for approximately seven years with diagnoses of somatoform and anxiety disorders, repeat EEG and brain imaging revealed underlying hydrocephalus. The aim of this study is to emphasize that electroencephalography (EEG) is a noninvasive method that can contribute to the diagnostic process in psychiatry. The case involves a 33-year-old woman with unexplained seizures and headaches who had been treated for approximately seven years under diagnoses of somatoform disorder (F45.3) and anxiety disorder (F41.3), initially with psychotherapy and subsequently with an anxiolytic and an SSRI. Her symptoms did not improve, and she was later diagnosed with anxiolytic and sedative dependence (F13). During the assessment, EEG was performed after it was determined that her anxiety had increased and her irritability and headaches had progressively worsened. Video EEG showed groups and runs of sharp slow waves over the frontal regions, whereas a previous EEG had been within normal limits; subsequent computed tomography revealed moderate hydrocephalus. The patient experienced three consecutive seizures, an antiepileptic drug (AED) was initiated, and surgical treatment was performed following a neurosurgical consultation. The treatment regimen reported in the poster was oxcarbazepine 600 mg + 900 mg, levetiracetam 750 mg twice daily, and quetiapine 25 mg once daily. The SSRI and anxiolytics were discontinued, and the patient remains stable on two AEDs, with ongoing multidisciplinary follow-up involving psychiatry, neurology, and neurosurgery. In conclusion, in patients presenting with headaches and unexplained seizures (psychogenic non-epileptic seizures, PNES), EEG should be repeated several times, findings should be confirmed with brain imaging (CT or MRI), and close collaboration with neurology should be established.
