Introduction: Some epileptic syndromes are characterised by seizures that are difficult to control and are associated to delayed neuropsychomotor development, which results in a deterioration in the patient's quality of life as well as in that of his or her family.

Aim: To evaluate the use of cannabidiol as adjuvant therapy in patients with refractory epilepsies.

Patients and methods: An observational study was conducted by means of a survey addressed to the patient's caregiver. Data collected included information about the patient and the caregiver, changes observed in the seizures, neuropsychological effects, side effects and the family's overall perception following the use of cannabidiol.

Results: The evaluation examined 15 patients with refractory epilepsies, who received cannabidiol over a period ranging from one month to one year. The frequency of seizures decreased in 40% of the patients, 60% of the patients were seen to have control over 50% of their seizures and in 27% of them the seizures disappeared completely. Neurocognitive changes were also reported: behaviour improved in 73%; 60% reported an improvement in language; in 50% sleep improved; 43% reported improvements in eating habits; and 100% said their mood had improved. The overall perception of the illness was that there had been improvements in 73% of respondents. The most common side effects were drowsiness and fatigue.

Conclusions: These results suggest a possible beneficial effect of cannabidiol on the control of seizures and on the improvement of certain neurocognitive aspects in patients with refractory epilepsies.

Introduccion. Algunos sindromes epilepticos se caracterizan por crisis de dificil control y asocian un retraso en el desarrollo neuropsicomotor, lo que conlleva un deterioro en la calidad de vida del paciente y su familia. Objetivo. Evaluar el uso del cannabidiol como tratamiento adyuvante en pacientes con epilepsias refractarias. Pacientes y metodos. Se realizo un estudio observacional por medio de una encuesta dirigida a la persona cuidadora del paciente. Se valoro la informacion sobre el paciente y el cuidador, cambios observados sobre las crisis, efectos neuropsicologicos, efectos adversos y percepcion global de la familia tras el uso del cannabidiol. Resultados. Se evaluo a 15 pacientes con epilepsias refractarias, quienes recibieron cannabidiol durante un periodo de un mes a un año. En el 40% de los pacientes hubo una disminucion en la frecuencia de las crisis, en el 60% de los pacientes se observo un control de mas del 50% de las crisis y en el 27% las crisis desaparecieron totalmente.
