title: The value of home video with ambulatory EEG: a prospective service review.
abstract: OBJECTIVE
  The demand for long term EEG monitoring is increasing with the emphasis on recording patients' attacks. Outpatient ambulatory EEG is relatively inexpensive and widely available. The main disadvantage of the technique is the lack of video which can make interpretation of an ictus difficult. We investigated whether patients, if offered home video equipment, would take it, if this resulted in simultaneous EEG-video capture of an ictus and if interpretation of the recording was facilitated by the video.
  
  
  METHODS
  All ambulatory EEG patients, adults and children, were offered a camcorder to take home during a 17-month study period.
  
  
  RESULTS
  130 patients/carers were offered a camcorder (93 adults, 37 children), 45 patients (35%) accepted; the main reason for not accepting was that attacks were considered too brief to record. An ictal event occurred in 34 patients (76%) with a camcorder; in 17 (50%) of these an attack was captured successfully on video. The main reasons for failure to capture events were that attacks were too brief, or that the camcorder was not operated successfully. Attacks were captured with greater success in children (14/23, 61%) than adults (3/11, 27%). Of the 17 video recordings, 14 (82%) were helpful in aiding interpretation of the ambulatory EEG.
  
  
  CONCLUSIONS
  In our study, home video facilities aided interpretation of ambulatory EEG recordings in approximately one third of patients. Technological advances and familiarity with portable recording devices will improve this figure and patients and their carers should be encouraged to use such facilities when available.
