    Immunization stress-related responses presenting as psychogenic non-epileptic seizures following HPV vaccination in Rio Branco, Brazil
    (2020) MARCHETTI, Renato Luiz; GALLUCCI-NETO, Jose; KURCGANT, Daniela; PROENCA, Inah Carolina Galatro Faria; VALIENGO, Leandro da Costa Lane; FIORE, Lia Arno; PINTO, Lecio Figueira; MARANHAO, Ana Goretti Kalume; OLIVEIRA, Maria Tereza da Costa; OLIVEIRA, Lucia Helena de
    Importance: The absence of a positive diagnosis of psychogenic non-epileptic seizures (PNES) in immunization stress-related response (ISRR) clusters may have not only a direct impact on affected patients' health but may also reduce compliance to national vaccination programs. It is therefore crucial to develop efficient diagnostic tools and a feasible proposal for proper communication and treatment of ISRR. Purpose: To explore the psychogenic nature of patients' convulsive seizures in a suspected outbreak of an ISRR cluster following human papillomavirus vaccination in Rio Branco, Brazil. Methods: Twelve patients with convulsive seizures were submitted to prolonged intensive videoelectroencephalography monitoring, brain magnetic resonance imaging, cerebrospinal fluid diagnostic testing, laboratory subsidiary examinations, and complete neurological and psychiatric evaluations. Results: Ten patients received the positive diagnosis of PNES, and two patients received the diagnosis of idiopathic generalized epilepsy. No biological association was found between the HPV vaccine and the clinical problems presented by the patients. Conclusions: Prolonged VEEG monitoring can contribute significantly to the positive diagnosis of PNES in ISRR clusters and to avoid hesitancy to vaccinate.

    Psychogenic nonepileptic seizures and psychogenic movement disorders: two sides of the same coin?
    (2014) PAOLA, Luciano De; MARCHETTI, Renato L.; TEIVE, Helio Afonso Ghizoni; LAFRANCE- JR., W. Curt
    Psychogenic nonepiteptic seizures (PNES) and psychogenic movement disorders (PMD) are commonly seen in Neurology practice and are categorized in the DSM-5 as functional neurological disorders/conversion disorders. This review encompasses historical and epidemiological data, clinical aspects, diagnostic criteria, treatment and prognosis of these rather challenging and often neglected patients. As a group they have puzzled generations of neurologists and psychiatrists and in some ways continue to do so, perhaps embodying and justifying the ultimate and necessary link between these specialties.
