It remains uncertain whether long-term use of benzodiazepines is associated with age-related cognitive decline, and if cognitive ability in early life is the driver of any association. This study examines the association of cognitive ability in young adulthood with later use of benzodiazepines and explores whether the use of benzodiazepines during adult life is associated with cognitive decline in late midlife.

The study samples include cognitive tests on the Børge Priens Prøve (BPP) from the conscription board examination (age 19 years) from 335 513 men born 1949–1961 and data from re-examinations of 5183 men 44 years later. Cognitive decline was defined as the difference between scores at the conscription board and the re-examination. Information on purchases of benzodiazepines was obtained from the Danish National Prescription Registry, 1995–2022. Associations were analysed using Cox proportional hazards and linear regression.

In total, 120 911 (36%) men purchased benzodiazepines during a follow-up of 20 years. Lower cognitive scores in young adulthood were associated with a higher risk of initiating benzodiazepines (hazard ratio [95% CI] = 0.71[0.68–0.75]). Men with the highest cumulative use of benzodiazepines had larger cognitive decline (β-coefficient [95% CI] = −1.66 [−2.09 to −1.23] BPP scores) compared with never users. Current benzodiazepine users showed a larger cognitive decline than never users (β-coefficient [95% CI] = −2.42[−3.18 to −1.66] BPP scores) and this partially explained the above association. These estimates for cognitive decline were relatively small and may lack clinical relevance.

Low cognitive ability increases the risk of benzodiazepine use in adulthood and cognitive decline is more pronounced in those with the highest benzodiazepine use compared with never-use, but the difference lacks clinical significance.

A nationwide register-based cohort study from Finland including 48 124 incident benzodiazepines and related drug (BZDR) users aged 18–65 years who initiated use in 2006 and were not dispensed BZDRs during 2004–2005. The follow-up was 5 years or until death, whichever occurred first.

To investigate sociodemographic and clinical factors associated with high-dose use of BZDRs (i.e. Z-drugs) among new BZDR users.

The temporal BZDR dose was calculated as a point estimate every 6 months after initiation as defined daily doses (DDDs) per day, based on the PRE2DUP method (an approach based on mathematical modelling of personal drug purchasing behaviours). Sociodemographic and clinical factors associated with dose categories were studied using multinomial logistic regression.

During the 5-year follow-up, very high-dose BZDR use was observed in 7.4% (n = 3557) and medium high-dose use in 25.5% (n = 12 266) of the users (corresponding to ≥30 mg and 10–29 mg in diazepam equivalents, respectively). Very high-dose use was more common among men compared with women (10.9% versus 4.6%). Very high-dose use patterns were especially observed in younger age groups (18- to 25-year-olds). Compared with oxazepam, initiating BZDR use with clonazepam (adjusted odds ratio 3.86, 95% CI 3.24–4.60), diazepam (2.05, 1.78–2.36) or alprazolam (1.76, 1.52–2.03) was associated with increased odds for very high-dose use. Both medium high-dose and very high-dose BZDR use were associated with a lower level of education. In all, 58% of very high-dose use occurred in BZDR users who received their first prescription from general practitioners.

Clinicians should be aware of the dose escalation risk especially when prescribing diazepam, alprazolam or clonazepam for psychiatric indications. If BZDRs are needed, our findings suggest favouring oxazepam.

Evidence suggests that cannabis may be a causal factor for development of schizophrenia. We aimed to investigate whether use of antipsychotic medication, benzodiazepines, and psychiatric service use differs among patients with schizophrenia depending on whether psychosis was precipitated by a diagnosis of cannabis use disorder (CUD).

We utilized the nationwide Danish registries to identify all individuals with an incident diagnosis of schizophrenia from 1995 to 2016. We also collected information on whether first CUD diagnosis preceded schizophrenia and thus defined a group of potentially cannabis-related schizophrenia. We compared the cannabis-related schizophrenia group both with all non-cannabis-related patients with schizophrenia and with non-cannabis-related patients with schizophrenia that were propensity-score matched to cases using a range of potentially confounding variables.

We included 35 714 people with incident schizophrenia, including 4116 (11.5%) that were cannabis-related. In the unmatched-comparison analyses, there were no clear differences over time in use of antipsychotics and benzodiazepines related to whether the diagnosis of schizophrenia was cannabis-related. After propensity-score matching, use of antipsychotics and benzodiazepines was significantly lower among cannabis-related cases of schizophrenia. In the unmatched comparison, the cannabis-related group had significantly more days admitted than the non-cannabis-related group. This was markedly attenuated after propensity-score matching.

Our findings indicate the importance of considering cannabis-related cases of schizophrenia as a potentially distinct disorder in terms of prognosis. It is unclear, however, if these differences are due to different biological types of schizophrenia being compared or if they rather indicate behavioral differences such as reduced adherence and treatment-seeking.

Benzodiazepines and related drugs (BZDRs) are widely used in the treatment of anxiety and sleep disorders, but cognitive adverse effects have been reported in long-term use, and these may increase the risk of labor market marginalization (LMM). The aim of this study was to investigate whether the risk of LMM is associated with new long-term BZDR use compared to short-term use.

This register-based nationwide cohort study from Finland included 37,703 incident BZDR users aged 18–60 years who initiated BZDR use in 2006. During the first year of use, BZDR users were categorized as long-term users (≥180 days) versus short-term users based on PRE2DUP method. The main outcome was LMM, defined as receipt of disability pension, long-term sickness absence (>90 days), or long-term unemployment (>180 days). The risk of outcomes was analyzed with Cox regression models, adjusted with sociodemographic background, somatic and psychiatric morbidity, other types of medication and previous sickness absence.

During 5 years of follow-up, long-term use (34.4%, N = 12,962) was associated with 27% (adjusted Hazard Ratio, aHR 1.27, 95% CI 1.23–1.31) increased risk of LMM compared with short-term use. Long-term use was associated with 42% (aHR 1.42, 95% CI 1.34–1.50) increased risk of disability pension and 26% increased risk of both long-term unemployment and long-term sickness absence.

These results indicate that long-term use of BZDRs is associated with increased risk of dropping out from labor market. This may be partly explained by cognitive adverse effects of prolonged BZDR use, which should be taken into account when prescribing BZDRs.

Emerging meta-analytical evidence indicates that baseline exposure to antipsychotics and to antidepressants in individuals at clinical high-risk for psychosis (CHR-P) have opposite prognostic effects as regards imminent transition to psychosis, with antipsychotics associated with higher risk and antidepressants associated with a lower risk in comparison to not-exposed individuals. Despite their common use, baseline exposure to benzodiazepines (BDZ) in CHR-P has surprisingly received poor attention as a potential risk modulator for transition to psychosis. The current systematic review and meta-analysis were performed to fix such a knowledge gap.

Systematic scrutiny of Medline and Cochrane library, performed up to 31 December 2022, searching for English-language studies on CHR-P reporting numeric data about the sample, the transition outcome at a predefined follow-up time and raw data on BDZ baseline exposure in relation to such outcome.

Of 1893 identified records, five studies were included in the systematic review and meta-analysis. The proportion of participants with exposure to BDZ at baseline ranged from 5.5% (one study) to 46.2%, with an average of 16.8%. At the end of the period of observation, i.e., the follow-up as reported in the study, 28.4% [95% confidence interval (CI) 19.7–39.1%] participants developed psychosis among the BDZ-exposed against 9.3% (7.3 to 11.9%) among the controls. CHR-P participants who were already under BDZ treatment at baseline had more than double chance of transition to psychosis than CHR-P participants who were BDZ-naïve. The risk ratio (RR) was 2.42 (95% CI 1.38–4.23) in the common effects model (z = 3.09; p = 0.002), and 2.40 (1.53 to 3.77) in the random-effects model (z = 5.40; p = 0.006; tau-squared = 0.0). There was no relevant heterogeneity: Cochran's Q = 1.49; df = 4; p = 0.828; I2 = 0.0% (95% CI 0.0–79%). Quality was good in four studies.

Ongoing BDZ exposure at inception in CHR-P is associated with a higher risk of transition to psychosis at follow up. This meta-analytic association, which echoes a similar effect of baseline antipsychotic exposure, plausibly indicates that the clinicians' prescription of pharmacological intervention captures some form of prognostically-relevant information (e.g. an anxiety permeated mental state requiring BDZ prescription) that are not adequately encompassed by current CHR-P categorical criteria.

Only three population-based observational human studies provided evidence that benzodiazepines (BZD) are associated with clinically adverse respiratory outcome. Striking was the finding that BZD drug exposure was associated with a 32% significantly increased adjusted risk of all-cause mortality, including, of note, the subgroup of individuals with no comorbidities. Causation, however, cannot be inferred in observational study design and, highly likely, recipients received BZD’s in these studies to help treating anxiety related to inter alia pre-existing respiratory symptoms.

Based on one fatal particular case, authors of current rapport explain what can go wrong when BZD’s are given in patient with respiratory impairment.

Authors provide a model on how an increase in carbon dioxide can lead to impaired cerebral autoregulation in a person with pre-existing respiratory decompensation. Discussion of integrative metabolic and vascular physiology.

Case rapport of a 18 y.o. otherwise healthy man, who was hospitalized with a novel episode of diabetic ketoacidosis accompanied by profound hypocapnia and anxiety, and who deteriorated and died shortly after airway management because of a clinically important acid-base balance disturbance caused by increased carbon dioxide. All the blood tests and results of respiratory monitoring were collected and carefully assessed.

Current case suggests that the P(CO(2))--HCO(3) hypothesis is consistent with known data on impaired cerebral autoregulation in diabetic ketoacidosis, driven mainly by increased levels of pCO2. In our opinion, it indicates the recommendation not to administrate BZD’s in patients with pre-existing compensatory hyperventilation as it may counter to the logic of adaptive physiology.

The social media platform Reddit is a contemporary context where we have an opportunity to identify problems experienced by people regarding different aspects of life. The platform is virtually anonymous which might make users discuss their problems more freely. Reddit is divided in subreddits where different subjects are discussed and the discussions are controlled by creators and moderators. I have identified a quite active subreddit targeted towards recovering addicts of benzodiazepines; r/benzorecovery.

* To analyze strategies of recovery in user narrative * To identify techniques commonly used and the how they are described * To construct metadata in order to assess how frequent the discussion of a different techniques are

Technically, what is done in this study, is adding mark-up metadata to different discussion. A rudimentary form of analysis suitable with a larger digital corpus where content metadata is added (Gilliland Swetland 2000). The metadata is constructed through a hermeneutical method in which the researcher analyses the subreddit.

Answering question like: Example: DIY-tapering; different ways to limit drug use by using less. 1) how common are discussion of taperings in relation to other subjects? 2) Is tapering commonly discussed together with other subjects and techniques?

Using a method of categorization and metadata mark-up we could gain a good understanding of the problems among recovering benzodiazepine addicts. We will also have the possibility to identify concepts that addicts themselves discuss and relate these to professional concepts thus creating better possibilities of communication between professionals and clients.

Benzodiazepines (BZD) are psychotropic drugs prescribed in psychiatry for their anxiolytic, hypnotic and sedative properties. Several guidelines aimed to limit the chronic use of BZDs. However, BZDs prescribing that does not comply with international recommendations remains widespread, estimated in France at 20% for hypnotic BZDs.

The aims of our study were to evaluate BZDs prescribing practices in the treatment of insomnia and to assess their compliance with international recommendations.

This is a cross-sectional study conducted through a Google-forms self-administered questionnaire,intended for psychiatrists and psychiatric residents, over a period of two months, from April 1 to May 31, 2019.

One hundred physicians practicing in psychiatry answered our questionnaire. The response rate was 28%. Four BZDs are recommended for the treatment of insomnia, none of which is available in Tunisia. Almost the third of the participants did not systematically look for signs of sleep apnea syndrome before treating an insomnia (30.5%). For treating insomnia, the majority of the participants began by indicating hygieno-dietetic rules (64%), 4% prescribed directly a BZD. Cognitive behavioral therapy was not indicated at all by the particiants. The maximum duration of prescribing BZDs in insomnia was 4 weeks in 20% of cases, and more than 4 weeks in 38% of cases. Among the participants, 41% prescribed BZDs for the treatment of chronic insomnia.

Insomnia appear to be badly managed and early drug prescribing is frequent. These practices do not comply with the recommendations of good practice and increase the risk of dependance and other side effects.

Benzodiazepines (BZD) are psychotropic drugs prescribed in psychiatry for their anxiolytic, hypnotic and sedative properties. Since anxiety, agitation and insomnia are common in psychoses and mood disorders, BZDs are frequently prescribed in the treatment of these pathologies. Guidelines remain rare with regard to the use of BZDs in the treatment of psychosis and bipolar disorder.

Our study aimed to evaluate BZDs prescribing practices in psychoses and bipolar disorder and to assess the specific risks related to the use of these molecules in the population suffering from severe mental disorder.

This is a descriptive cross-sectional study conducted through a Google-forms self-administered questionnaire, intended for psychiatrists and psychiatric residents, over a period of two months, from April 1 to May 31, 2019.

One hundred physicians practicing in psychiatry answered our questionnaire. The response rate was 28%. BZDs were prescribed during thymic or psychotic relapses by 88.6% of the participants. During relapses, the main indication for BZDs was anxiety (81.3%), insomnia (80.2%), and catatonia (59.4%). Among the participants, 24.8% indicated that they maintained a long-term treatment with BZDs in patients with psychosis, and 11.4%in patients with bipolar disorder. The participants estimated that the long-term use of BZDs in patients with severe mental disorder represented an increased risk of : dependence (94.3%), behavioral disinhibition (30.5%), suicide (22.9%), anger, hostility and violence (31.4%).

Few guidelines concern the use of BZDs in psychosis and bipolar disorder. However, this prescription remains very frequent in current practice, with clinical and therapeutic features specific to this population.

Benzodiazepines (BZD) are psychotropic drugs prescribed in psychiatry for their anxiolytic, hypnotic and sedative properties. Several guidelines aimed to limit the chronic use of BZDs. However, BZDs prescribing that does not comply with international recommendations remains widespread, estimated in France at 30% for anxiolytic BZDs.

The aims of our study were to evaluate BZDs prescribing practices in the treatment of anxiety and to assess their compliance with international recommendations.

This is a cross-sectional study conducted through a Google-forms self-administered questionnaire,intended for psychiatrists and psychiatric residents, over a period of two months, from April 1 to May 31, 2019.

One hundred physicians practicing in psychiatry answered our questionnaire. The response rate was 28%. The most prescribed BZD for anxiolytic purposes was Prazepam (76.2%). Clonazepam was prescribed for anxiolytic purposes in 10.5% of cases. Of the 105 participants, 48 indicated that they prescribed BZDs for anxiolytic purposes in states of acute stress (45.7%), 28.6% prescribed them for the treatment of mild to moderate anxiety manifestations in anxiety disorders. For the treatment of anxiety without panic attacks, 20% indicated that they prefer a short half-life BZD, 80% a long half-life BZD. The maximum duration of BZDs prescription for anxiolytic purposes was 12 weeks (62%), and 6 months in 10% of cases.

BZDs are often prescribed in psychiatry for their anxiolytic property, sometimes in a way that does not comply with the recommendations of good practice, with regard to the prescribed molecules, their indications and the duration and modalities of prescription.
