Las convulsiones psicógenas no-epilépticas (CPNE) son parecidas a las convulsiones de tipo epiléptico, lo que suele traer mucha confusión al momento de ofrecer un diagnóstico diferencial. La diferencia medular radica en que las CPNE no son producidas por anomalías electrocorticales, y sí por factores psico-emocionales. En el presente artículo, presentamos una revisión actualizada del tema, con énfasis en aspectos fenomenológicos, de diagnóstico y de curso clínico. Para ilustrar la complejidad de las CPNE, presentamos varias viñetas clínicas que se basan en la experiencia del primer autor con más de 100 pacientes con CPNE. De nuestra revisión se desprende que las CPNE se relacionan a un menoscabo y a un deterioro marcado generalizado psicosocial. Esta situación se agrava cuando típicamente pasan años antes de ofrecerse el diagnóstico correcto. Asimismo, estudios retrospectivos y prospectivos documentan el punto de que típicamente más del 50% de estos pacientes presentan un historial previo de abuso físico, emocional y sexual. Al respecto, se presenta un modelo multicausal/multifactorial para dar cuenta de las variables que predisponen, precipitan y perpetúan la aparición de las CPNE.
Psychogenic nonepileptic seizures (PNES) are likely to be confused with epileptic seizures. The main difference is that PNES are not produced by anomalous electrical brain discharges, but by emotional and psychological dysfunctions. In the present article, we present an empirical and conceptual update on PNES, emphasizing the phenomenological, diagnostic and natural course of the disorder. To illustrate the clinical complexity of PNES, we present several clinical vignettes. We conclude that PNES are elated to psychosocial burden and to impairment in several important areas of living. This situation is aggravated when the esearch literature indicate that many PNES patients are misdiagnosed with epilepsy and do not receive adequate psychological/psychiatric care. Furthermore, patients with PNES typically report high rates of a wide plethora of abusive hildhood experiences. Lastly, we present a biopsychosocial conceptual framework to understand the emergence of this disorder.
