| Abstract |
The present study was designed to describe the socio-demographic, clinical, and polysomnographic features of patients diagnosed with narcolepsy in our sleep center. This retrospective cross-sectional study was conducted on 181 patients diagnosed with narcolepsy based on the results of clinical evaluation, polysomnography (PSG), and multiple sleep latency test (MSLT) between 1993 and 2009. Approximately 70% of the patients had cataplexy, whereas 42% had hallucinations and 55.8% had sleep paralysis. Although sleep efficiency was higher (91.28 ± 5.89%) in patients with narcolepsy, they woke frequently during the night, and their percentages of deep sleep were low (stage 3, 5.12 ± 3.08%, stage 4, 9.60 ± 7.10%). Our study group was divided into two based on age: individuals aged <30 years (n = 152) and >30 years (n = 29). REM latency on PSG was shorter (t = 2.96, p = 0.004) and sleep onset REM (SOREM) on MSLT was higher (t = 2.56, p = 0.011) in the older group than in the younger group. Cataplexy is seen in most patients with narcolepsy. In older patients, REM latency on PSG is shorter and the number of SOREM on MSLT is higher. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 September 2013.
All research outputs
#21,699,788
of 24,217,893 outputs
Outputs from Acta Neurologica Belgica
#613
of 809 outputs
Outputs of similar age
#144,664
of 159,247 outputs
Outputs of similar age from Acta Neurologica Belgica
#11
of 11 outputs
Altmetric has tracked 24,217,893 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 809 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.9. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 159,247 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
