Narcolepsy Questionnaire
                           We have also developed several less 
                            commonly used paper and pencil neuropsychiatric instruments 
                            which are applied when appropriate. One is the Neppe 
                            narcolepsy screen which has not been well researched. 
                            Narcolepsy is a rare condition itself (incidence possibly 
                            1 in several thousand individuals). However, the questionnaire 
                            is far more versatile probing sleep disturbance as 
                            well as anomalistic experiences and these are common 
                            in the CHIT patient. Unfortunately, the questionnaire 
                            needs to be scored by paper and pencil at this stage 
                            and there are no norms so that although highly relevant 
                            history information is obtained at a clinical level, 
                            a clinician needs to interpret the results.
