Excessive Daytime Sleepiness

Objective: To determine the sleep pattern of students as well as to calculate their sleep efficiency.
Material and Methods: The study was conducted in the Physiology Department of Khyber Medical College, Peshawar.
First and Second Year MBBS students of Khyber Medical College were selected who were above 18 years age.Students
were given a self designed questionnaire to fill and then their sleep efficiency (SE) was calculated using total time in
bed (TIB) and total sleep time (TST).
Results: Total number of students inducted in the study was 115. Their average bedtime and wake up time were midnight
and 7.00 AM respectively. The average time in bed was documented as 10 hours. The Total Sleep Time reported
was around 7 and a half hours. The average Sleep Efficiency of the students was computed to be 83.9%. Only 1.7%
students used sleep-inducing medications, while caffeine consumption was 17%. Students’ perception of their sleep
quality and their work efficiency was good, on Likert scale.
Conclusions: The average sleep efficiency computed was good when compared to standards around the world. The
sleep patterns including bedtime and wakeup time of majority of the students were healthy.

Purpose The current meta-analysis aimed to obtain a more stable estimate of the effect size of Ramadan diurnal intermittent fasting (RDF) on sleep duration and daytime sleepiness.

Methods Databases (Scopus, ScienceDirect, ProQuest Medical, PubMed/MEDLINE, Web of Science, EBSCOhost, Cochrane, CINAHL, and Google Scholar) were searched from database inception to the end of June 2019. The sleep quality measures analyzed were excessive daytime sleepiness (EDS) measured by the Epworth sleepiness scale (ESS) and total sleep time (TST). Subgroup analyses for age, sex, and levels of physical activity were conducted.

Results We identified 24 studies (involving 646 participants, median age 23.7 years, 73% men) conducted in 12 countries from 2001 to 2019. The results revealed that TST decreased from 7.2 h per night [95% confidence interval (CI) 6.7-7.8] before Ramadan to 6.4 h (95% CI 5.3-7.5) during Ramadan, while the ESS score increased slightly from 6.1 (95% CI 4.5-7.7) before Ramadan to 7.0 (95% CI 5.2-8.8) during Ramadan. Effect sizes on sleep quality measures during RDF demonstrated a moderate reduction in TST (number of studies, K = 22; number of subjects, N = 571, Hedges' g value of −0.43, 95% CI − 0.64 to −0.22, Q = 90, τ 2 = 0.15, I 2 = 78%, P < 0.001), while ESS score showed negligible effect on EDS (K = 9, N = 362, Hedges' g value of −0.06, 95% CI −0.43 to 0.28, Q = 21, τ 2 = 0.13, I 2 = 76%, P value = 0.001).

Conclusion During the month of Ramadan, there is approximately a 1 hour reduction in TST and nearly a 1 point increase in the ESS score.

Delayed sleep phase syndrome (DSPS) is a circadian rhythm sleep disorder in which the timing of the sleep episode occurs later than desired and is associated with difficulty falling asleep, problems awakening on time (e.g., to meet work or school obligations), and daytime sleepiness. The phase relationship between the timing of sleep and endogenous circadian rhythms is critical to the initiation and maintenance of sleep, and significant alteration leads to impairment of sleep quality and duration. The aim of this retrospective study was to determine the phase relationship between sleep-wake times and physiological markers of circadian timing in clinic patients with DSPS. Objective and subjective measures of sleep timing and circadian phase markers (core body temperature and melatonin) were measured in patients with DSPS and compared with age-matched controls. As expected, significant delays in the timing of the major sleep episode and circadian phase of body temperature and melatoni...

Purpose To measure the effect of a 2-day sleepcoaching seminar on daytime sleepiness and sleep-related variables of shift workers employed in an Austrian railway company (ÖBB: Österreichische Bundesbahnen). Method Participants filled in pre- and post-intervention questionnaires, containing items of the PSQI and the ESS, questions about chronotype, personality factors and possible burnout risk factors. About 30 shift workers, working in shifts for more than 300 months on average (28 male; mean age = 24 ± 45.90, age range 24–56 years) voluntarily took part in the investigation twice. Sleep coaching by Holzinger and Kloesch™ (SC) is a new holistic approach for non-pharmacological treatment of non-restorative sleep and is based on Gestalt therapy. It includes psychotherapeutic aspects, which enable clients to improve their sleep quality by developing one’s own coping strategies which can be implemented in daily routine. Dream work and relaxation techniques are also part of the programme...

Purpose: To measure the effect of a 2-day sleepcoaching seminar on daytime sleepiness and sleep-related variables of shift workers employed in an Austrian railway company (ÖBB: Österreichische Bundesbahnen).
Method: Participants filled in pre- and post-intervention questionnaires, containing items of the PSQI and the ESS, questions about chronotype, personality factors and possible burnout risk factors. About 30 shift workers, working in shifts for more than 300 months on average (28 male; mean age = 24 ± 45.90, age range 24–56 years) voluntarily took part in the investigation twice. Sleep coaching by Holzinger and KloeschTM (SC) is a new holistic approach for non-pharmacological treatment of non- restorative sleep and is based on Gestalt therapy. It includes psychotherapeutic aspects, which enable clients to improve their sleep quality by developing one’s own coping strategies which can be implemented in daily routine. Dream work and relaxation techniques are also part of the programme.
Results: The 2-day SC seminar was beneficial by focusing on the sleep problems related to shift work. A significant improvement of the global PSQI score and the PSQI variables subjective sleep quality, diurnal fatigue, and sleep latency was achieved, with a medium effect size. However, the programme did not result in the reduction of daytime sleepiness (ESS). Six more variables did not change significantly.
Conclusion: While some sleep problems related to shift work were successfully addressed by SC, daytime sleepiness (ESS) could not be reduced contrary to our expectations. More research with a greater sample and a longitudinal design is needed to examine the long-term effects of SC.

Background Narcolepsy-cataplexy is characterized by excessive daytime sleepiness with recurrent episodes of irresistible sleep, cataplexy, hallucinations and sleep paralysis. Its aetiology is unknown, but it is positively associated with the human leukocyte antigens (HLA) in all studied populations. The purpose of the present study was to investigate the association of HLA class II DRB1/DQB1 alleles with narcolepsy-cataplexy in Mexican Mestizo patients. Methods This is a case-control study of consecutive patients and ethnically matched controls. We included 32 patients diagnosed with typical narcolepsy-cataplexy, of the National Institute of Neurology, of the Institute of Psychiatry and at the Center of Narcolepsy at Stanford University. As healthy controls, 203 Mexican Mestizos were included. DRB1 alleles were identified using sequence based typing. A PCR-SSOP reverse dot blot was used for DQB1 typing. Allele frequency was calculated by direct counting and the significance of the d...

Obstructive sleep apnoea (OSA) is a common condition affecting approximately 4% of middle-aged individuals. The condition is more common in men with a history of snoring. Patients experience fragmented sleep caused by repetitive obstruction of the upper airway during sleep. There is mounting evidence that OSA is associated with metabolic syndrome. Metabolic syndrome comprises hypertension and type 2 diabetes, with

OBJECTIVE: To evaluate excessive daytime sleepiness in patients with depressive disorder and to examine its association with the severity of depression and suicidal ideation. METHOD: Seventy patients were interviewed and assessed by the Epworth Sleepiness Scale (ESS), the Beck Depression Inventory (BDI) and the Beck Scale for Suicidal Ideation (SSI). Descriptive analysis, Pearson correlations and Student&#39;s t-test were used for data analyses. RESULTS: Most of the patients (57.1%) obtained high scores on the ESS. Correlation was positive and strongly significant between ESS scores and BDI scores, as well as between ESS scores and SSI scores. Patients with high ESS scores obtained higher mean BDI and SSI scores in comparison to patients with lower ESS scores. Significant differences (p &lt; 0.05) were encountered when the patients with higher (&gt;10) and lower (&lt; 10) ESS scores were compared in terms of total ESS, BDI and SSI scores. CONCLUSIONS: Excessive daytime sleepiness wa...

Sleep disorders are common complaints in patients with neurodegenerative diseases such as spinocerebellar ataxia type 3 (SCA3) or Machado–Joseph disease (MJD)—SCA3/MJD. We evaluated the frequency of sleep disorders in SCA3/MJD patients against controls matched by age and gender, and correlated data with demographic and clinical variables. The main sleep disorders evaluated were rapid eye movement (REM) sleep behavior disorder (RBD),

Sleep apnea is the cessation of breathing during sleep. These episodes result in hypoxemia and sleep disruption; thus the consequences are both cardiorespiratory and neural. Sleep apnea syndrome is defined by a constellation of signs and symptoms, with the main presenting symptom being excessive daytime sleepiness. A diagnosis requires documentation of episodes of abnormal breathing during sleep. This disorder, once thought to be very rare, is so common that it is unlikely that any busy clinician has not encountered a case. Facilities for the evaluation of sleep breathing disorders are now available in most communities. With the introduction of continuous positive airway pressure and other treatments, most patients have complete resolution of their disabling symptoms.

There is now strong evidence from animal studies and, in humans, from epidemiological studies as well as from retrospective and prospective intervention studies, that obstructive sleep apnea (OSA) can cause persistent hypertension not only during sleep but during waking hours as well. There is also some evidence that habitual snoring alone, even without OSA, can do the same. Many of the hitherto unexplained epidemiological, clinical, biochemical, hematological, and physiological abnormalities seen in essential hypertension (EH) could be explained by the accompanying sleep related breathing disorders (SRBD). Many cases of resistant hypertension are probably due to SRBD. Recent studies show that SRBD are extremely common in EH but that the vast majority of patients with these sleep disorders are being missed by physicians who are treating the accompanying hypertension, even when the patients already have blatant symptoms of OSA. Recent investigations have shown that the probable reaso...
