Usefulness of short-term video EEG recording with saline induction in pseudoseizures.
OBJECTIVE
To study the usefulness of short-term recording of video electroencephalography (VEEG) as an outpatient procedure with placebo induction (PLIN) and intravenous saline in cases of pseudoseizures (Psz).


METHODS
Fifty cases of suspected Psz were enrolled. They were divided into 2 groups: Group 1 consisted of patients with frank Psz, Group 2 those where diagnosis was uncertain. VEEG recording was done and 10 ml of saline used for placebo-induction.


RESULTS
Of 50 patients, 24 (48%) were in Group 1 and 26 (52%) in Group 2. Fifteen (30%) had a spontaneous event during VEEG and 33% had an event only on PLIN. The diagnosis was confirmed in 60 %. In 24% of patients anti-epileptic drugs were discontinued.


CONCLUSIONS
Short-term monitoring with VEEG using PLIN is a useful initial screening procedure and in patients where it is inconclusive, long term recordings may be done.
