Tardive dyskinesia (TD) occurs in patients receiving antipsychotic treatment with dopamine receptor antagonists. Despite the prevalence of TD and its negative impact on patients' lives, there has been a lack of approved treatments and limited evidence from controlled trials of pharmacological treatment. Areas covered: PubMed was searched for English-language papers published during 2007-2016 using terms "tardive dyskinesia" or "drug-induced movement disorder", and "treatment". Studies evaluating pharmacological agents for the treatment of TD were selected...

Intracranial epidermoids are space-occupying lesions of rare variant. Although cerebropontine angle and parasellar region are common sites of occurrence, it has been reported in various other parts of the intracranial cavity. Headache and features of increased intracranial tension are the common clinical manifestation. Report of psychiatric symptoms as the initial presentation of epidermoid is not known in literature except a single case report, which describes mutism to be the manifestation of intracranial epidermoid...

BACKGROUND: Given the complex nature of symptom presentation and medication regimens, psychiatric clinics may benefit from additional tools to personalize treatments. Utilizing pharmacogenetic information may be helpful in assessing unique responses to therapy. We report herein a case of wearing-off phenomena during treatment with aripiprazole long-acting injectable (LAI) and a proof of concept strategy of how pharmacogenetic information may be used to assess possible genetic factors and also hypothesize potential mechanisms for further study...

The central nervous system-specific serotonin receptor 2C (5HT2C) controls key physiological functions, such as food intake, anxiety, and motoneuron activity. Its deregulation is involved in depression, suicidal behavior, and spasticity, making it the target for antipsychotic drugs, appetite controlling substances, and possibly anti-spasm agents. Through alternative pre-mRNA splicing and RNA editing, the 5HT2C gene generates at least 33 mRNA isoforms encoding 25 proteins. The 5HT2C is a G-protein coupled receptor that signals through phospholipase C, influencing the expression of immediate/early genes like c-fos...

The first-line treatment for psychotic disorders remains antipsychotic drugs with receptor antagonist properties at D2-like dopamine receptors. However, long-term administration of antipsychotics can upregulate D2 receptors and produce receptor supersensitivity manifested by behavioral supersensitivity to dopamine stimulation in animals, and movement disorders and supersensitivity psychosis (SP) in patients. Antipsychotic-induced SP was first described as the emergence of psychotic symptoms with tardive dyskinesia (TD) and a fall in prolactin levels following drug discontinuation...

One of the most interesting but tenebrous parts of the bipolar disorder (BD) story is the switch between (hypo)mania and depression, which can give bipolar patients a thrilling, but somewhat perilous, 'ride'. Numerous studies have pointed out that there are some recognizable differences (either state-dependent or state-independent) in several brain regions of people with BD, including components of the brain's reward system. Understanding the underpinning mechanisms of high and low mood statuses in BD has potential, not only for the development of highly specific and selective pharmaceutical agents, but also for better treatment approaches and psychological interventions to manage BD and, thus, give patients a safer ride...

BACKGROUND: Schizophrenia is a chronic disease that requires long-term management with antipsychotics; however, an important barrier to the success of long-term treatment is drug noncompliance, which increases the risk of recurrence and hospitalization. Second-generation long-acting injectable antipsychotics have improved drug adherence, and the pharmacological effects of the drugs, and therefore, have become useful treatment options. METHODS: We report on three schizophrenia patients who switched from oral low-dose aripiprazole to aripiprazole once-monthly 300 mg...

Importance: It has remained unclear whether there are clinically meaningful differences between antipsychotic treatments with regard to preventing relapse of schizophrenia, owing to the impossibility of including large unselected patient populations in randomized clinical trials, as well as residual confounding from selection biases in observational studies. Objective: To study the comparative real-world effectiveness of antipsychotic treatments for patients with schizophrenia...

Reasons for using antipsychotic polypharmacy (APP) in routine clinical practice, despite a potentially unfavorable risk-benefit ratio, are poorly understood. This research aimed to determine (1) if severe courses of schizophrenia were associated with APP and (2) if a schizophrenia-related acute event would predict a switch to APP in the short term. Observational prospective data (at baseline and 6months) were drawn from a French nationwide cohort ("Cohorte Générale Schizophrénie"), which included 1859 inpatients and outpatients with schizophrenia...

The exact modalities of switching between two antipsychotics are rarely studied despite the high frequency of this issue in clinical practice. In this context, description of clinical cases may be enlightening. We report on three new cases of agitation after replacing a dopaminergic antagonist with aripiprazole. A literature review indicated no other predictive clinical feature associated with a higher risk of agitation than therapeutic history. In fact, patients who previously received a greater dose of antipsychotic are more at risk to present paradoxical agitation when switching to aripiprazole...

Dopamine D2-receptor blockade by antipsychotic medication reduces psychotic symptoms, but may reduce subjective well-being. The current study aims to further explore the relation between dopamine D2-receptor affinity and subjective well-being within a large sample of patients with psychotic disorders. Patients participated in a longitudinal naturalistic cohort study: the Genetic Risk and Outcome of Psychosis (GROUP) study. Three groups of antipsychotic medication were created on the basis of their affinity for the D2-receptor: (i) loose or partial agonistic binding, (ii) moderate binding, and (iii) tight binding...

BACKGROUND: Studies suggest that antipsychotic-induced weight gain is not a great concern in the elderly population. This study investigated the weight change in elderly patients with various treatment duration and antipsychotics. Part 1 of the study was to determine whether atypical antipsychotics induced weight change in elderly patients. Part 2 was to determine whether certain atypical antipsychotics induced more weight change in elderly patients. METHODS: In Part 1, a retrospective chart review was done on 115 geriatric inpatients...

Tardive dystonia is characterized by sustained, generally slow involuntary twisting movements. It is estimated to occur at a frequency of 1% to 4% among patients who are taking an antipsychotic agent. Unlike the first generation antipsychotics, the second generation antipsychotics are less likely to cause neuroleptic-induced movement disorder. For aripiprazole, only a few cases have been reported for tardive dystonia. We present a young male, who developed a severe tardive dystonia after taking aripiprazole for 5 years...

Schizophrenia is associated with brain glutamate dysfunction, but it is currently unclear whether antipsychotic administration can reduce the extent of glutamatergic abnormality. We conducted a systematic review of proton magnetic resonance spectroscopy ((1)H-MRS) studies examining the effects of antipsychotic treatment on brain glutamate levels in schizophrenia. The Medline database was searched to identify relevant articles published until December 2016. Inclusion required that studies examined longitudinal changes in brain glutamate metabolites in patients with schizophrenia before and after initiation of first antipsychotic treatment or a switch in antipsychotic treatment...
