José M Gavilán, Juan Haro
This article allows consulting the performance data of 96 Spanish university students in two personality questionnaires and two theory of mind (ToM) tasks. Personality dimensions were evaluated through the OPERAS questionnaire (Vigil-Colet et al., 2013) [1], which evaluates global personality through 5 scales: extraversion, agreeableness, conscientiousness, emotional stability, openness to experience, and the ESQUIZO-Q questionnaire (Fonseca-Pedrero et al., 2010) [2], which assesses schizotypy by means of 10 subscales: ideas of reference, magical thinking, unusual perceptual experiences, odd thinking and language, paranoid ideation, physical anhedonia, social anhedonia, odd behavior, lack of close friends, and excessive social anxiety...

Abnormally low γ-aminobutyric acid (GABA) levels have been consistently reported in adults with major depressive disorder (MDD). Our group extended this finding to adolescents, and documented that GABA deficits were associated with anhedonia. Here we aimed to confirm our prior finding of decreased brain GABA in youth with depression and explore its associations with clinical variables. Forty-four psychotropic medication-free youth with MDD and 36 healthy control (HC) participants (12-21 years) were studied...

PURPOSE: Little research has been done to identify possible cancer-related fatigue (CRF) subtypes and to classify cancer survivors accordingly. We aimed to identify CRF subtypes in a large population-based sample of (long term) stage I-III colorectal cancer survivors. We also identified factors associated with the CRF subtypes. METHODS: Respondents completed the Multidimensional Fatigue Inventory and other validated questionnaires on anxiety and reduced positive affect (anhedonia), sleep quality, and lifestyle factors (body mass index and physical activity)...

BACKGROUND: Chronic stress-induced inflammatory responses occur in part via danger-associated molecular pattern (DAMP) molecules, such as high mobility group box 1 protein (HMGB1), but the receptor(s) underlying DAMP signaling have not been identified. METHODS: Microglia morphology and DAMP signaling in enriched rat hippocampal microglia were examined during the development and expression of chronic unpredictable stress (CUS)-induced behavioral deficits, including long-term, persistent changes after CUS...

BACKGROUND: Attenuated positive symptom syndrome (APSS), characterized by 'putatively prodromal' attenuated psychotic-like pathology, indicates increased risk for psychosis. Poor premorbid social adjustment predicts severity of APSS symptoms and predicts subsequent psychosis in APSS-diagnosed individuals, suggesting application for improving detection of 'true' prodromal youth who will transition to psychosis. However, these predictive associations have not been tested in controls and therefore may be independent of the APSS diagnosis, negating utility for improving prediction in APSS-diagnosed individuals...

Dopamine (DA) neurotransmission within the brain's reward circuit has been implicated in the pathophysiology of depression and in both, cognitive and pharmacological mechanisms of treatment response. Still, a direct relationship between measures of DA neurotransmission and reward-related deficits in patients with depression has not been demonstrated. To gain insight into the symptom-specific alterations in the DA system in patients with depression, we used positron emission tomography (PET) and the D2/3 receptor-selective radiotracer [(11)C]raclopride in twenty-three non-smoking un-medicated Major Depressive Disorder (MDD) patients and sixteen healthy controls (HC)...

BACKGROUND: Emotion deficits may be the basis of negative symptoms in schizophrenia patients and they are prevalent in these patients. However, inconsistent findings about emotion deficits in schizophrenia suggest that there may be subtypes. AIM: The present study aimed to examine and profile experiential pleasure, emotional regulation and expression in patients with schizophrenia. METHODS: A set of checklists specifically capturing experiential pleasure, emotional regulation, emotion expression, depressive symptoms and anhedonia were administered to 146 in-patients with schizophrenia and 73 demographically-matched healthy controls...

The FDA recently extended their regulatory authority to electronic cigarettes (ECs). Because the abuse liability of ECs is a leading concern of the FDA, animal models are urgently needed to identify factors that influence the relative abuse liability of these products. The ability of tobacco products to induce nicotine dependence, defined by the emergence of anhedonia and other symptoms of nicotine withdrawal following cessation of their use, contributes to tobacco abuse liability. The present study compared the severity of precipitated withdrawal during chronic infusion of nicotine alone or nicotine-dose equivalent concentrations of three different EC refill liquids in rats, as indicated by elevations in intracranial self-stimulation (ICSS) thresholds (anhedonia-like behavior)...

OBJECTIVES: Obstructive sleep apnea (OSA) is a common clinical problem that can have serious health consequences and complicate the course of mental disorders. It is estimated that the prevalence of sleep apnea in patients with bipolar disorder can be 21-47.5%. Some symptoms of OSA are the same as the symptoms of depression: daytime drowsiness, cognitive dysfunction, decreased drive, apathy, depressed mood, anhedonia. METHODS: We present a case of a patient whose depressive symptoms persisted despite repeated changes of pharmacological treatment and were exacerbated by severe sleep disorder...

Olfactory dysfunction and emotional impairment are nonmotor symptoms in Parkinson disease (PD). These symptoms might be correlated with the appearance of Lewy bodies and neurites (ubiquitin and α-synuclein aggregates) in the amygdala (Braak stage 3). α-Synucleinopathy in the amygdala has been studied only occasionally, and no data on cell types involved are available. This work aimed to analyze α-synuclein expression in the basolateral, central, and cortical amygdaloid nuclei in 5 PD patients (Braak stages 3-5) and 5 controls...

The mechanisms underlying chronic stress-induced dysfunction of glutamatergic transmission that contribute to helplessness-associated depressive disorder are unknown. We investigated the relationship of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and stress, and the neuroplastic changes of stress-induced depression-like behavior in the ventrolateral periaqueductal gray (vlPAG). We conducted whole-cell patch-clamp electrophysiological recordings in the vlPAG neurons. Depression-like behavior was assayed using tail suspension test and sucrose preference test...

Patients receiving the cytokine immunotherapy, interferon-alpha (IFN-α) frequently present with neuropsychiatric consequences and cognitive impairments. Patients (25-80%) report symptoms of depression, including, anhedonia, irritability, fatigue and impaired motivation. Our lab has previously demonstrated treatment (170,000IU/kg sc, 3 times per week for 4weeks) of the pro-inflammatory cytokine, IFN-α, induced a depressive phenotype in rats in the forced swim test (FST). Here, we examine the biological mechanisms underlying behavioral changes induced by IFN-α, which may be reflective of mechanisms underlying inflammation associated depression...

BACKGROUND: Although Parkinson's disease (PD) is characterized by progressive neurodegeneration of multiple neurotransmitter systems, 6-hydroxydopamine (6-OHDA) as a model substance is mainly used to selectively damage the nigrostriatal dopaminergic neurons and induce parkinsonian-like motor disturbances in rats. We hypothesized that high doses of this neurotoxin affecting other monoaminergic systems may also evoke the depressive-like behavior. METHODS: The impact of 6-OHDA (8, 12, 16μg/4μl) administered unilaterally into the medial forebrain bundle on the sucrose solution intake (a measure of anhedonia) and on the tissue levels of noradrenaline (NA), dopamine (DA) and serotonin (5-HT) in the striatum (STR), substantia nigra (SN), prefrontal cortex (PFC) and hippocampus (HIP) was examined in rats pretreated or non-pretreated with desipramine...

Nearly all self-report measures of anhedonia have been developed for use in adults. Recently we developed an age and developmentally appropriate measure of social/interpersonal pleasure for adolescents (ACIPS-A), whereby lower scores are indicative of social anhedonia. However the scale had not been administered to Eastern samples. The adolescent version of the Anticipatory and Consummatory Interpersonal Pleasure Scale (ACIPS-A) was administered to a general, community-derived Chinese adolescent sample of 442 students, including 186 males (44%), who ranged in age from 12 to 18 years old...

The ability to predict reward promotes animal survival. Both dopamine neurons in the ventral tegmental area (VTA) and serotonin neurons in the dorsal raphe nucleus (DRN) participate in reward processing. Although the learning effects on dopamine neurons have been extensively characterized, it remains largely unknown how the response of serotonin neurons evolves during learning. Moreover, while stress is known to strongly influence reward-related behavior, we know very little about how stress modulates neuronal reward responses...

OBJECTIVE: The use of labor pain relief medications is a controversial issue that has engendered heated discussions among health care professionals about safety, interference with birthing, and breastfeeding. METHODS: This is a case-control study with 62 puerperae treated with nitrous oxide and 124 control women (ratio 1:2), matched for age, gestational age, parity, delivery route, labor augmentation, and spinal regional analgesia. We tested anhedonia, anxiety, and depression symptoms at hospital discharge by The Edinburgh Postnatal Depression Scale (EPDS), and the intensity of nitrous oxide labor pain relief and satisfaction memory by a retrospective Visual Analog Scale (VAS, 0-10 Numeric Rating Scale) at a set cut off time of 3 months of a child's age...
