We report the case of a 19-year-old female patient who had progressive chorea associated with a GNAO1 mutation. Chorea was refractory to multiple anticonvulsants, and the patient suffered from tiapride-induced neuroleptic malignant syndrome. After identification of a GNAO1 missense mutation at the age of 18years, topiramate treatment was initiated and the frequency of chorea decreased dramatically. The efficacy of topiramate may have been related to the inhibitory modulation of voltage-activated Ca(2+) channels...

Several lines of evidence suggest that pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide playing an important role as a neuromodulator. It has been indicated that PACAP is associated with mental diseases, and that regulation of the PACAPergic signals could be a potential target for the treatment of such psychiatric states as schizophrenia. Recent studies have suggested that action of neuroleptic drugs is mediated not only by dopaminergic and serotonergic neurotransmission, but also via neuropeptides which may act both as neurotransmitters and as neuromodulators...

Previous studies have demonstrated depressive or hibernation-like roles of phenothiazine neuroleptics [combined chlorpromazine and promethazine (C + P)] in brain activity. This ischemic stroke study aimed to establish neuroprotection by reducing oxidative stress and improving brain metabolism with post-ischemic C + P administration. Sprague-Dawley rats were subjected to transient (2 or 4 h) middle cerebral artery occlusion (MCAO) followed by 6 or 24 h reperfusion, or permanent (28 h) MCAO without reperfusion...

Crisis at the end of life are exceptional challenges for patients, relatives and therapists. With respect to the individual treatment goals and the patients' autonomy, therapeutic action should be commenced in an adequate manner in order to preserve the patients' quality of life as much as possible. Advance care planning for specific critical scenarios may be helpful in order to treat patients according to their wishes and values even if they are not capable to express themselves. Furthermore, a crisis plan can define the scope of action for therapists in emergency situations...

The proportion of pregnancies exposed to either second-generation antipsychotics (SGAs) or first-generation antipsychotics (FGAs) varies between 0.3%-2% of all pregnancies, but, until now, little is known about the potential neurobehavioral teratogenicity of antipsychotics. Assessing this safety facet is the aim of this article. PubMed, Scopus, and Google Scholar were searched for eligible articles. PubMed (1954 to May 2016) was searched using several medical subject headings, variously combined. PubMed search results were also limited using the search filter for human studies published in English...

This safety assessment provides a detailed analysis of key studies and focuses on the six most widely used antipsychotic drugs. Lines of evidence include mechanisms of action, short-term treatment of psychosis, relapse prevention, early intervention in schizophrenia, long-term comparisons between first- and second-generation agents, and flexible treatment algorithms. Despite the diversity of study settings, several common features were seen. All the agents obstruct normal signaling through widely dispersed dopamine D2 receptors...

A 27-year-old woman with panic disorder taking 20 mg olanzapine daily for 4 months was admitted to our hospital because of disturbed consciousness with fever, hyperglycemia, hyperosmolarity, and elevated creatine phosphokinase. She was diagnosed with a hyperosmolar hyperglycemic state (HHS) and neuroleptic malignant syndrome (NMS). Brain magnetic resonance imaging (MRI) showed transiently restricted diffusion in the splenium of the corpus callosum (SCC), with a high signal intensity on diffusion-weighted imaging...

Drug-induced parkinsonism (DIP) is classically described as acute/subacute, bilateral symmetric syndrome in which tremor is infrequent compared to Parkinson's disease. Most DIP cases are caused by classic (CN) and second-generation neuroleptics (SN), and calcium channel blockers (CCB). We evaluated potentially distinctive demographic and clinical features in DIP among different drug classes. This was a prospective study of reversible DIP related to single selected drugs on each class. Baseline assessment included demographic, clinical data, and scales for staging, severity of motor signs of parkinsonism, tremor, and other involuntary movements...

Well-established practice guidelines and a solid body of evidence underpin the safe and effective use of electroconvulsive therapy (ECT), primarily in mood disorders. In this issue of the journal, 3 case reports deal with situations that fall outside of the usual guidelines: treatment resistance to ECT overcome by combined use with antidepressant medication; use of ECT in the presence of polymyositis; and use of ECT for an unusually severe case of neuroleptic malignant syndrome, assisted by consultation from an online expert resource...

Our team at Emory University Hospital contacted experts at the National Network of Depression Centers (NNDC) for clinical guidance concerning a patient with schizophrenia hospitalized in the intensive care unit with a complex case of prolonged delirium secondary to neuroleptic malignant syndrome (NMS). Through the NNDC, leading psychiatrists across the United States with expertise in electroconvulsive therapy (ECT) provided us with treatment strategies based on experience in our area of concern. This report describes our use of ECT to treat severe NMS in this patient with schizophrenia, utilizing the recommendations made by the NNDC's ECT experts concerning electrode position, number and frequency of treatments, and selection of anesthetic induction agents...

BACKGROUND: Tardive dyskinesia (TD) is a serious side effect of long-term administration of typical neuroleptics, such as haloperidol. The pathophysiology of TD remains unclear, but the experimental evidence suggests that free radical-induced neuronal apoptosis in the basal ganglia may play an important role. PURPOSE: This study was to investigate changes in Bax and Bcl-2 expression levels in TD-associated brain regions and the effects of the antioxidant EGb761 on Bax and Bcl-2 levels in an animal model of TD...

Abnormal involuntary movements often improve in response to anti-dopaminergic drugs. In contrast to classic neuroleptics that block dopamine receptors, drugs that deplete presynaptic dopamine by blocking vesicular monoamine transporter type 2 (VMAT2) seem to be safer and have little or no risk of tardive dyskinesia. This is one reason why there has been a recent emergence of novel VMAT2 inhibitors. Areas Covered: Since the approval of tetrabenazine, the classic VMAT2 inhibitor, in the treatment of chorea associated with Huntington disease (HD), other VMAT2 inhibitors (e...

Chronic hepatitis C virus (HCV) infection causes severe liver disease and affects ca. 146 million individuals. Novel directly acting antivirals targeting HCV have revolutionized treatment. However, high costs limits access to therapy. Recently, several related drugs used in humans to treat allergies or as neuroleptics emerged as potent HCV cell entry inhibitors. Insights into their antiviral mode of action may access opportunities for drug repurposing in hepatitis C and possibly other important human viral infections...

Lucie Gerber, Jean-Paul Gaudillière
This article investigates the redefinition of depression that took place in the early 1970s. Well before the introduction of the third edition of the Diagnostic and Statistical Manual of Mental Disorders, this rather rare and severe psychiatric disorder hitherto treated in asylums was transformed into a widespread mild mood disorder to be handled by general practitioners. Basing itself on the archives of the Swiss firm Ciba-Geigy, the article investigates the role of the pharmaceutical industry in organizing this shift, with particular attention paid to research and scientific marketing...

Thioridazine (TZ), an antipsychotic drug, renders multidrug-resistant (MDR) cancer cells susceptible to cytotoxic agents to which they were initially resistant, has anti-prolilferative activity and apoptosis-inducing properties in various tumor cell lines and cancer stem cells. Whereas the anti-proliferative activity takes place at high concentrations that ensure the intercalation of the compound between nucleic bases (especially rich in G/C bases), much lower concentrations inhibit the export function of the ABCB1 (P-glycoprotein), which is responsible for the MDR phenotype of the cancer cell...
