Introduction: Alexithymia, characterized by difficulty identifying and expressing emotions, is commonly observed in individuals with psychiatric and neurological disorders. However, its prevalence in patients with epilepsy (PWE), particularly in those with drug-resistant epilepsy (DRE), remains under-researched. This study investigates the prevalence of alexithymia in patients with DRE and explores its associated factors.
Methods: We conducted a retrospective observational study of 118 adult patients with focal DRE undergoing presurgical evaluation at Bordeaux University Hospital. Alexithymia was assessed using the Toronto Alexithymia Scale-20 (TAS-20), while psychiatric symptoms were evaluated with validated scales. Data on demographic characteristics, epilepsy duration, seizure frequency, antiepileptic drug use, and localization of the epileptogenic zone (EZ) were collected and analyzed using logistic regression models.
Results: Alexithymia was identified in 40.7 % of patients. Depression and anxiety were significantly associated with alexithymia (p < 0.01), whereas no correlation was observed between alexithymia and the localization or lateralization of the EZ.
Discussion: These findings suggest that alexithymia is prevalent among patients with DRE, with significant associations to depression and anxiety. The high prevalence of affective symptoms underscores the importance of early identification and intervention for alexithymia to improve outcomes in patients with DRE.

Triangulating evidence from the GALENOS living systematic review on trace amine-associated receptor 1 (TAAR1) agonists in psychosis.

Population Health Sciences, Bristol Medical School, University of Bristol, UK.
Background: Trace amine-associated receptor 1 (TAAR1) agonists offer a new approach, but there is uncertainty regarding their effects, exact mechanism of action and potential role in treating psychosis.
Aims: To evaluate the available evidence on TAAR1 agonists in psychosis, using triangulation of the output of living systematic reviews (LSRs) of animal and human studies, and provide recommendations for future research prioritisation.
Method: This study is part of GALENOS (Global Alliance for Living Evidence on aNxiety, depressiOn and pSychosis).
Are ADHD trajectories shaped by the social environment? A longitudinal study of maternal influences on the preschool origins of delay aversion.

Background: Attention-deficit/hyperactivity disorder (ADHD) is commonly attributed to neuro-cognitive deficits of genetic and/or prenatal/perinatal environmental origins. Sonuga-Barke proposed an alternative formulation, suggesting that ADHD behaviors are functional expressions of delay aversion-a strong motivational disposition to avoid or escape negative affective states evoked by delay. It is hypothesized that the strength of this disposition, though neuro-biologically rooted, is exacerbated by early negative social interactions during waiting-related encounters.

Resting-state functional connectivity (rsFC) measures have enjoyed significant success in discovering the neuropathological characteristics of schizophrenia (SZ), bipolar disorder (BD), and attention deficit/hyperactivity disorder (ADHD). However, it is unknown whether and how the spatial and temporal coupling relationships across rsFC measures would be altered in these psychiatric disorders. Here, resting-state fMRI data were obtained from a transdiagnostic sample of healthy controls (HC) and individuals with SZ, BD, and ADHD.

Background: Symptom severity and social functioning are important outcomes after first episode psychosis (FEP), yet current evidence about associations between them is inconsistent and lacks (subclinical) momentary insights.
Methods: The current Ecological Momentary Assessment (EMA) study was conducted in 58 people in remission from FEP, as part of the HAMLETT (Handling Antipsychotic Medication: Long-term Evaluation of Targeted Treatment) trial. At baseline, participants were prompted to report momentary mental states and social context 10x/day for eight consecutive days, including psychotic experiences (PEs), motivation/drive and negative affect, that may indicate proxies of (subclinical) psychotic, negative and general affective symptoms, respectively.
