Summary: This study compared CSF and serum levels of LPGDS in patients with central hypersomnia and healthy controls. The results showed that LPGDS levels were significantly lower in control subjects compared to patients with EDS complaints, but there were no significant differences in L-PGDS levels between different types of hypersomnia. Serum L-PGDS correlated modestly and negatively with sleep latency in hypersomnia subjects.

Summary: Harriet Tubman, a hero of the abolitionist movement, experienced sleep attacks and visions as a result of a head injury in her childhood. While her contemporaries attributed these experiences to her deep faith, modern understanding suggests that her sleep attacks may be more related to post-traumatic narcolepsy than temporal lobe epilepsy. This case study not only sheds light on Tubman's life but also allows for a review of long-term effects of traumatic brain injuries and provides insights into the pathophysiology, diagnosis, and treatment of narcolepsy.

Summary: This meta-analysis examines the polysomnography (PSG) differences between narcolepsy type 1 (NT1)/type 2 (NT2) and idiopathic hypersomnia (IH), finding significant differences in sleep parameters between NT1 and IH, but not between NT2 and IH. The results suggest that NT1 exhibits shallower and more fragmented sleep compared to IH, while the sleep characteristics of NT2 and IH without long sleep time are very similar.

Summary: This study investigated the relationship between craniopharyngioma, sleep, and excessive need for sleep. Compared with the control group, patients with craniopharyngioma were more likely to be obese, had shorter sleep latency, and slept longer on the first night. Treatment with stimulants was effective in 90% of the patients.

Summary: Patients with narcolepsy often experience comorbidities related to emotional, metabolic, sleep, and immune health, which significantly impact their quality of life and clinical outcomes. This review aims to enhance understanding of the complex presentations by exploring the literature on comorbidities in narcolepsy patients and encourages a multidisciplinary approach to improve clinical and quality of life outcomes.

Summary: Idiopathic hypersomnia, first described in 1976, has undergone multiple name changes and descriptions over the years, but still lacks clear diagnostic criteria. Recent research has proposed dividing idiopathic hypersomnia into subtypes based on long sleep duration or the absence of it.

Summary: This study aimed to determine the changes in muscle tone (atonia index, AI) at different levels of vigilance during the multiple sleep latency test (MSLT) and each nap in narcolepsy patients. The results showed that AI during wakefulness was significantly higher in narcolepsy patients compared to other hypersomnia patients. AI during REM sleep and wakefulness in naps with sudden onsets of REM sleep periods were lower in NT1 than in NT2. AI during wakefulness had a high diagnostic value in distinguishing patients with other hypersomnias, while AI during REM sleep and wakefulness in naps with SOREMP showed a poor ability to differentiate NT1 and NT2.

Summary: Modafinil demonstrates efficacy in improving symptoms of idiopathic hypersomnia, with potential for adverse effects. Clarithromycin does not show significant effectiveness in treating idiopathic hypersomnia. Additional studies are needed to further explore treatment options for this condition.

Summary: The study compared patterns of regional brain metabolism in patients with idiopathic hypersomnia (IH), narcolepsy (NT1), and non-sleepy controls. The results showed that NT1 and IH patients have somewhat overlapping but distinct regional metabolism patterns.

Summary: This study explored the diagnostic value of selected sleep and vigilance tests beyond the multiple sleep latency test in differentiating between central disorders of hypersomnolence and fatigue syndromes. The results showed that SVT parameters had a high sensitivity and specificity in distinguishing between clinically suspected diagnoses. Although it was not possible to establish an overall prediction model based on SVTs alone, a combination of careful clinical assessment and SVTs improved the differentiation of central disorders of hypersomnolence.

Summary: This study evaluated the performance of implantable cardiac devices for sleep apnoea diagnosis and found that they have a clinically relevant respiratory disturbance index, which may improve access to sleep apnoea diagnosis in at-risk cardiovascular populations.

Summary: Video-polysomnography (v-PSG) is essential for diagnosing rapid eye movement (REM) sleep behavior disorder (RBD). This study addresses the need for comprehensive and unambiguous v-PSG recommendations to diagnose RBD and identify prodromal RBD, aiming to provide objective v-PSG measures and enable future harmonized multicentric studies and clinical trials.

Summary: This study found that loss-of-function mutations in the PSAP gene were present in patients with iRBD, and the co-occurrence with GBA variants suggests a potential genetic interaction. These findings may have implications for understanding the prodromal stage of synucleinopathy and the development of Parkinson's disease.

Summary: This study compared the clinical, MRI, and CSF findings of patients with anti-IgLON5 with patients with progressive supranuclear palsy (PSP) and functional neurologic disorder. The results indicate that patients with anti-IgLON5 have inflammatory changes in routine CSF analysis, an increase in B-lymphocyte frequency, and the presence of plasma cells, suggesting the importance of inflammatory mechanisms in these cases.

Summary: Anti-IgLON5 disease is an autoimmune encephalopathy characterized by sleep disturbances. It has a wide range of clinical symptoms, including movement disorders, bulbar dysfunction, autonomic disorders, and neurocognitive impairment. This study reports a case of an 87-year-old woman with isolated progressive hemichorea. A literature review identified multiple cases of anti-IgLON5 disease with chorea as an extrapyramidal movement disorder in their clinical phenotype. Screening for IgLON5 antibodies should be considered in patients with unexplained movement disorders, including isolated hemichorea.

Summary: The study investigated the reasons and benefits of dual diagnostic assessments using video-polysomnography (VPSG) and prolonged video-EEG-monitoring (pVEEG-M). The majority of cases involved the diagnosis or monitoring of different comorbid diseases, while in other cases, both modalities were useful to achieve a higher diagnostic accuracy or to refute differential diagnoses. The combination of VPSG and pVEEG-M complement each other, especially in cases of two different comorbid diseases, to rule out differential diagnoses or when a higher diagnostic certainty is sought.
