We subsequently assessed the presence of eventual differences between these eight hPRL patients with EDS, but without another neurologic, psychiatric, or sleep disorder and hPRL patients with a complaint of EDS associated with another sleep disorder, in terms of age, PRL levels, ESS, MMSE, and PSG parameters (available in seven and 18 participants, respectively); this comparison is reported in Table 3. Here, PRLR is linked to sleep disorder.
