A comprehensive review on the efficacy of S-Adenosyl-L-methionine in Major Depressive Disorder.

Objective: To review the antidepressant efficacy of S-Adenosyl-L-Methionine (SAMe) both in monotherapy and/or in augmentation with antidepressants to better understand its potential role in the treatment of patients with Major Depressive Disorder (MDD) and Treatment-Resistant Depression (TRD).

Data Sources: A MEDLINE/PubMed search was carried out by using the following set of keywords: ((SAMe OR SAdenosyl- L-Methionine) AND (major depressive disorder OR depression)). Data Selection and Data Extraction: No language or time restrictions were placed on the electronic searches.

Treatment of antipsychotic-induced hyperprolactinemia: an update on the role of the dopaminergic receptors D2 partial agonist aripiprazole.

Hyperprolactinemia is an unwanted adverse effect present in several typical and atypical antipsychotics. Aripiprazole is a drug with partial agonist activity at the level of dopamine receptors D2, which may be effective for antipsychotic- induced hyperprolactinemia. Therefore, we analyzed the literature concerning the treatment of antipsychoticinduced hyperprolactinemia with aripiprazole by updating a previous paper written on the same topic.

The potential of pregabalin in neurology, psychiatry and addiction: a qualitative overview.

Pregabalin is an anticonvulsant drug that binds to the α₂δ (alpha2delta) subunit of the voltage-dependent calcium channel in central nervous system (CNS). Pregabalin decreases the release of neurotransmitters, including glutamate, norepinephrine, substance P and calcitonin gene-related peptide. Purpose of this paper is to offer a qualitative overview of the studies currently available in literature about this drug, examining the effectiveness of pregabalin in its various fields of application.

The role of intranasal oxytocin in the treatment of patients with schizophrenia: a systematic review.

Oxytocin is a nonapeptide mammalian hormone, best known for its role in childbirth, parturition and lactation. It has been implicated in the control of social behaviors and relationships, such as monogamy or promiscuous behaviors. The putative involvement of oxytocin in schizophrenia was first postulated following several pioneer reports of oxytocin use in schizophrenia and observations of increased oxytocin levels in the cerebrospinal fluid of schizophrenic patients, although this latter finding has subsequently been challenged.

Efficacy and safety of long acting injectable atypical antipsychotics: a review.

Schizophrenia is a chronic, severe and recurrent brain disorder that requires continuous, long-term treatment with antipsychotic medication to minimize relapse and provide clinical benefit to patients. For patients with schizophrenia, non-adherence to medication is a major risk factor for relapse and re-hospitalization. Long-acting injectable formulations of second-generation antipsychotics (SGAs-LAIs) provide constant medication delivery and the potential for improved adherence.

The emerging role of melatonin agonists in the treatment of major depression: focus on agomelatine.

Major Depressive Disorder (MDD) is an extremely disabling, chronic and recurrent disease. Moreover, subthreshold depressive symptoms often persist during periods of apparent remission. Such symptoms include sleep disturbances, sexual dysfunction, weight gain, fatigue, disinterest, anxiety, and/or emotional blunting, which do not often respond to available antidepressant treatments.

Alexithymia and its relationships with dissociative experiences and Internet addiction in a nonclinical sample.

The aim of the present study was to evaluate alexithymia, dissociative experiences, and Internet addiction (IA) in a nonclinical sample of 312 undergraduate students, identifying predictive factors associated with the possible risk of developing IA. We found that alexithymics had more consistent dissociative experiences, lower self-esteem, and higher obsessive-compulsive symptoms than nonalexithymics. In addition, alexithymics reported a higher potential risk for IA when compared to nonalexithymics.
