Introduction: According to the ILAE, the definition of epilepsy requires the occurrence at least one epileptic seizure. Up to 20% of patients diagnosed of epilepsy are not actually epileptic. An accurate diagnosis is necessary for a satisfactory management of patients with Epilepsy. New broad access image technologies allow patients and families to record homemade videos helping neurologists in diagnosis.

Method: During a two-year period in an epilepsy clinic, consecutive patients were encouraged to record their events with any available device. Instructions for good quality videos were given. Three neurologists/epileptologists watched the videos in clinical session, rated the quality of the recordings following some parameters and made a clinical diagnosis. In a second phase, previous diagnosis was revised.

Results: 314 consecutive patients (relatives) were encouraged to record events. 52% male. Average age: 46 years. 267 patients had video recording devices available (87%) (Photo camera: 100%, cell-phone: 100%, webcam: 10%, video camera: 30%). From this group, 135 (50%) felt unable to record events. Reasons given: Low seizure frequency: 60%, seizures short duration: 80%. 50 events from 22 patients recorded. Mean age: 35 years. Seizure frequency three months prior to video deposit was 3, 5 seizures/patient/month. Previous epileptic syndrome diagnosed (based on description/neuroimaging/EEG): 15 focal temporal lobe epilepsy, 4 focal frontal probably symptomatic epilepsy, 3 epileptic encephalopathy.

Type of seizures recorded: Focal motor with typical automatisms: 14 seizures/11 patients. Focal motor with hyperkinetic automatisms: 9 seizures/2 patients. Asymmetrical tonic motor seizures: 4 seizures/1 patient. Focal clonic seizure: 5 seizures/1 patients. Atypical absence seizure: 6 seizures/3 patients. Non-epileptic Seizure (NES): 13 seizures/3 patients. Postural tremor: 1 patient. There was agreement in diagnosis but in one. 18 patients were confirmed in their Diagnosis: Epilepsy misdiagnosis: 4. Three NES and one undetermined tremor.

Conclusion: Homemade videos may be of diagnostic value in epilepsy management. Training in performing good-quality videos is necessary. Webcam long term recordings should be recommended as the best recording option.
