Clinical features of psychogenic nonepileptic seizures: a study of 64 cases in southwest China.
This article describes the clinical features of psychogenic nonepileptic seizures (PNES) in people in southwest China. Patients with a confirmed diagnosis of pure PNES by video/EEG monitoring were retrospectively reviewed. A total of 64 patients with PNES were included, 32 (50%) of whom were male. Twenty (31.3%) patients had previously been misdiagnosed and treated for epilepsy. Psychological trauma and head injuries were considered antecedent traumatic factors. A history of abuse was rare. The PNES cases were divided into three subtypes: psychogenic minor motor seizures, psychogenic major motor seizures, and unresponsive seizures. Age at onset was identified as a predictor of prognosis. The results of this study demonstrated a higher prevalence of PNES in males compared with previous studies. The semiology of PNES in China is similar to that in Western countries. Classification of semiology may be helpful in the differential diagnosis of PNES.
