The nightmare severity index (NSI): A short new multidimensional tool for assessing nightmares.

This psychometric pilot study aims to evaluate a new multidimensional simple scale, named the nightmare severity index (NSI) - close to the existing insomnia (ISI) and hypersomnia (HSI) severity indexes. The NSI encompasses all main dimensions of nightmare disorder, evaluating four subdimensions: frequency, emotional impact, diurnal impact, and nocturnal impact of nightmares. The NSI was completed by a total of 102 patients. The majority of the population consisted of women (64%) and outpatient individuals (76%) diagnosed with mood disorders such as depression (31%) and bipolar disorder (41%). Comorbidity with post-traumatic stress disorder (PTSD) was prevalent (44%), and psychotropic medications were commonly used (47%). Internal validity analyses indicated that the NSI was well suited for exploratory factor analysis. All items demonstrated satisfactory correlations with the factors, and the questionnaire exhibited good internal consistency (Cronbach's alpha >0.7). Higher NSI scores were observed among individuals experiencing nightmare symptoms considering the DSM-5/ICSD-3 criteria. In summary, the NSI proves to be a promising and valuable tool for clinical practice, demonstrating good acceptability, internal validity, and the ability to assess nightmare severity.

Bad Dreams and Nightmares Preceding Suicidal Behaviors.

Objective: Nightmares seem to predict suicidal behaviors, and the aim of this study is to explore the chronology and trajectories of alterations in dream contents before a suicidal crisis, distinguishing 3 different experiences: bad dreams, nightmares, and suicidal scenarios during dreams.Methods: This naturalistic study included individuals hospitalized between January 2021 and May 2021 in a psychiatric post-emergency room unit for suicidal crisis (thoughts and attempts).Results: The study observed that 80% (n = 32/40) of patients had altered dreams (AD) before the suicidal crisis, including 27 (67.5%) with bad dreams, 21 (52.5%) with nightmares (bad dreams that awaken the sleeper), and 9 (22.5%) with suicidal scenarios during dreams. No differences were observed between the AD group versus patients with no altered dreams (ND) regarding sociodemographic characteristics. We observed a progression of dream content alterations: bad dreams appear 111 days (4 months) before the suicidal crisis, then nightmares appear 87.3 days before (3 months), and suicidal scenarios during dreams were reported 45.2 days before (1.5 months). For the AD and ND populations in suicidal crisis, 80% had at least 1 subtype of dream alterations, 40% had bad dreams and nightmares, and 17.5% had all 3 subtypes. The AD group, compared to the ND group, had significantly more family history of insomnia (P = .046). Almost all patients (97.5%) had depressive symptoms (Montgomery-Asberg Depression Rating Scale [MADRS] score ≥ 7; 82.5% had moderate to severe symptoms, MADRS ≥ 20), 60% had insomnia (Insomnia Severity Index > 14), 92.5% had altered sleep quality (Pittsburgh Sleep Quality Index > 5), and 57.5% reported sleepiness (Epworth Sleepiness Scale > 10).Conclusions: Dream alterations and their progression can be readily assessed and may help to better identify prodromal signs of suicidal behaviors.

Temporal trends in calls for suicide attempts to poison control centers in France during the COVID-19 pandemic: a nationwide study.

Concerns have been raised about early vs. later impacts of the COVID-19 pandemic on suicidal behavior. However, data remain sparse to date. We investigated all calls for intentional drug or other toxic ingestions to the eight Poison Control Centers in France between 1st January 2018 and 31st May 2022. Data were extracted from the French National Database of Poisonings. Calls during the study period were analyzed using time trends and time series analyses with SARIMA models (based on the first two years). Breakpoints were determined using Chow test. These analyses were performed together with examination of age groups (≤ 11, 12-24, 25-64, ≥ 65 years) and gender effects when possible. Over the studied period, 66,589 calls for suicide attempts were received. Overall, there was a downward trend from 2018, which slowed down in October 2019 and was followed by an increase from November 2020. Number of calls observed during the COVID period were above what was expected. However, important differences were found according to age and gender. The increase in calls from mid-2020 was particularly observed in young females, while middle-aged adults showed a persisting decrease. An increase in older-aged people was observed from mid-2019 and persisted during the pandemic. The pandemic may therefore have exacerbated a pre-existing fragile situation in adolescents and old-aged people. This study emphasizes the rapidly evolving situation regarding suicidal behaviour during the pandemic, the possibility of age and gender differences in impact, and the value of having access to real-time information to monitor suicidal acts.

Seasonal changes and decrease of suicides and suicide attempts in France over the last 10 years.

The objective of this study was to examine the evolution of suicides and suicide attempts over the last 10 years in France. We analyzed the number of deaths by suicide and suicide attempts in metropolitan France (2009-2018) from French national databases, on a daily, weekly or monthly basis. Seasonal variation in suicide rates was modeled using a cosinor function. Based on this model, we determined the association of suicides and suicide attempts with geographic characteristics, age, gender, means used and psychiatric disorders. The number of suicides and suicide attempts decreased over the last ten years in France (mean decrease of 14.49% and 11.69% per year). We observed a significant and recurrent seasonal pattern of suicides and suicide attempts in France, with a peak in spring. The suicide and suicide attempt rates were higher in the northern departments of France. Suicides were more frequent for men (75%) and middle-age individuals (45-54 years old), while suicide attempts were more frequent for women (62%) and young adults and middle-age individual (15-19 and 40-49 years old). Nearly two-thirds of the patients who attempted suicide suffered from comorbid psychiatric disorders. Mood disorders was the most frequent comorbid psychiatric disorder (54%). Voluntary drug intoxication was the most common means of suicide attempt (80%), and hanging was the most common means of suicide (54%). The number of suicides and suicide attempts decreased in France over the last 10 years, with large and recurrent seasonal variations. These findings could be used to alert and adjust prevention policies, as well as developing preventive strategies such as chronotherapeutics.

Impact of meteorological factors on alcohol use disorders: A study in emergency departments.

No data exist on the influence of meteorological factors on alcohol use disorders (AUD). The aim of this study was to investigate the relationship between meteorological factors and AUD. All patients who were admitted to an emergency department (ED) in the Paris-region for an alcohol-related condition were included using the Oscour® database over the period January 1, 2015 to December 31, 2019. Meteorological data were collected by Météo-France (French Weather service). All data were aggregated by week. We performed Pearson correlations between weather variables and the number of ED visits for AUD. We observed 98,748 ED visits for alcohol-related conditions over the study period. We found significant positive correlations between the number of alcohol-related ED visits and the mean temperature (r = 0.55; p = 1.87e -5, 95% Confidence Interval (CI) = 0.33, 0.72) and the duration of sunlight (r = 0.42; p = .0015, 95% CI = 0.17, 0.62). Negative correlations were also found significant with rain (r = -0.40; p = .0014, 95% CI = -0.62, -0.18), humidity (r = -0.41; p = .0023, 95% CI = -0.62, -0.16) and wind speed (r = -0.40; p = .0031, 95% CI = -0.60, -0.14). Emergency visits for AUD seem to increase with the temperature and duration of sunlight, and decrease with rain, humidity and wind speed. Further studies are needed on a larger scale and taking into account potential confounding factors to confirm these findings.

Functional Motor Symptoms in Parkinson's Disease and Functional Parkinsonism: A Systematic Review.

OBJECTIVE: Whereas functional symptoms are common in Parkinson's disease (PD), a parkinsonian syndrome may occasionally reflect a pure functional disorder (also named functional parkinsonism [FP]). This review aimed to decipher these entities to clarify the link between functional manifestations and PD. METHODS: Following the PRISMA guidelines, the authors performed a systematic literature search of the PubMed and Science Direct databases for the period 1988 to December 2018 to identify studies of patients with either FP or PD associated with functional neurological symptoms. RESULTS: From the 844 articles screened, 22 were retained, including 12 studies of functional neurological symptoms in PD and 16 studies of FP. The studies of functional symptoms in PD included 121 patients-57% were women, and the mean age was 61.3 years. Psychiatric history (mostly depression) and exposure to triggering stressors were frequent: 60% and 82.5%, respectively. The most common symptom was tremor (33.8%), most often located on the side most affected by PD (50%). Studies of FP included a total of 120 patients-62% were women, and the mean age was 50.7 years. The first FP symptoms appeared on average 5 years before diagnosis, with an abrupt onset in half the cases; 67.6% had a psychiatric history, and 46.8% were exposed to triggering stressors, such as physical injury, stress at work, or loss of family or friends. CONCLUSIONS: Findings suggest a possible relationship between PD and FP. Clinicians should keep in mind the possibility of functional symptoms in PD patients.
