In rats, social defeat by an aggressive opponent induces a state of anxiety, shown by a decrease in time spent on active explorative behaviour, an increase in immobility, a clear decrease in frequency of all active behavioural parameters (enhanced passivity). We tested the hypothesis whether acute or sub-chronic agomelatine would antagonize the negative consequences of a social defeat. As many ...

Managing cancer patients requires numerous drugs, such as chemotherapeutic agents and drugs for other chronic diseases. Thus, health teams must be aware of potential drug interactions that may be detrimental to health. This study analyzed the types of non-chemotherapeutic drugs used by cancer patients and screened patients undergoing cancer treatment for anxiety and depression. Methods: This cr...

Opipramol is considered as a pharmacological agent that does not fit the classification taking into account the division of antidepressants, antipsychotics and anxiolytics. It has a structure related to tricyclic antidepressants but it has a different mechanism of action, i.e. binding to sigma1 and to sigma2 sites. It has been regarded as an effective drug in general anxiety disorders together ...

OBJECTIVES Yoga and exercise have beneficial effects on mood and anxiety. γ-Aminobutyric acid (GABA)-ergic activity is reduced in mood and anxiety disorders. The practice of yoga postures is associated with increased brain GABA levels. This study addresses the question of whether changes in mood, anxiety, and GABA levels are specific to yoga or related to physical activity. METHODS Healthy su...

The neuropeptide S (NPS) system has been suggested to contribute to the pathogenesis of anxiety. In order to further characterize the cognitive-neurophysiological relevance of neuropeptide S in the etiology of anxiety, the influence of a functional neuropeptide S receptor gene (NPSR1) variant on response inhibition and error monitoring was investigated under consideration of the dimensional phe...

BACKGROUND Behavioural changes associated with idiopathic epilepsy (IE) have been identified in dogs, with fear and anxiety-related problems seen in both drug-naïve dogs and dogs treated with anti-epileptic drugs (AEDs). Treating anxiety-related behaviour in dogs with IE may be challenging, as seizures are a contraindication for many conventional anxiolytic drugs. In addition, many dogs with IE...

Lippia alba (Mill.) N.E. Brown (Verbenaceae) is widely used in different regions of Central and South America as a tranquilizer. The plant's anxiolytic properties, however, merit investigation. The present study evaluated the effects of repeated daily (14 days) intraperitoneal (ip) treatment with an essential oil (EO) from a chemotype of L. alba (LA, chemotype II, 12.5 and 25 mg/kg; N = 6-8) an...

In this paper we address the ethics of adopting delusional beliefs and we apply consequentialist and deontological considerations to the epistemic evaluation of delusions. Delusions are characterised by their epistemic shortcomings and they are often defined as false and irrational beliefs. Despite this, when agents are overwhelmed by negative emotions due to the effects of trauma or previous a...

A total of 90 patients including 30 patients of generalized anxiety disorder and 30 of dysthymic disorder according to DSM III criteria plus 30 patients of mixed anxiety-depressive disorder were given a detailed psychiatric evaluation and four rating scales were made for measuring the level of anxiety and depression at intake and to record their improvement with treatment. Half the subjects in ...

Psychiatric symptoms in Guillain-Barré syndrome (GBS) can include anxiety and affective lability, which require treatment to improve functional outcomes. Three cases in which modest doses of selective serotonin reuptake inhibitors (SSRIs), alone or in combination with anticonvulsants, reduced symptoms of anxiety and affective lability during acute rehabilitation of GBS are presented. These agen...
