When seizures are non-epileptic

Abstract

IntroductionNon-epileptic seizures (NES) are a diverse group of disorders, whose paroxysmal events can be mistaken for epilepsy, although they are caused by a mental or psychogenic process rather than a neurological cause.Objectives/methodsWe present a case of a 45-year-old female patient with history of generalized seizures prior to Meningioma resection in August 2015, referred to the Liaison Psychiatry outpatient follow up clinic at the Royal London Hospital after has gone several times to emergency department complaining about flush and hot sensation that proceeded to corners of mouth turning down, teeth chattering, shaking of left arm and torso at first and then legs. During the episodes, she was awake with no consciousness loss. Her mood was low, with clinical evidence of depression and she had very high levels of health anxiety.DiscussionA diagnosis of non-epileptic attacks was made in the sequence of those episodes. A holistic and multidisciplinary approach was made, including pharmacotherapy, cognitive-behavioral therapy and domiciliary support. The clinical response was good regarding both mood, anxiety levels and NES.ConclusionsApproximately 25% of patients who have a previous diagnosis of epilepsy and are not responding to drug therapy are found to be misdiagnosed and it is common that epileptic patients have both epileptic and non-epileptic seizures. Although distinguishing epileptic and non-epileptic seizures is not easy, there are some clinical clues that the physicians should look for, like age of onset, time of the day that episodes occur and presence or absence of postictal confusion.Disclosure of interestThe authors have not supplied their declaration of competing interest.
