REVIEW
W Hermann, D Huster
Wilson's disease is a rare genetic but treatable metabolic disorder which has a favorable prognosis when diagnosed early and treated adequately. Therefore, knowledge of this rare clinical condition and a reliable diagnosis are indispensable. The diagnostic work-up is initiated in cases of unexplained acute or chronic liver disease and/or an extrapyramidal motor disturbance occurring mostly between the 5th and 45th years of life. Manifestations with initial symptoms have occasionally been observed at an age younger than 1 year and later than 70 years...

Developing a mechanistic insight into the specific brain processes that underpin improvement in negative symptoms can help us design novel chemical and physical treatments against these unrelenting symptoms. The aim of the present study is to explore the longitudinal changes in the brain's regional functional efficiency that accompany improvement in negative symptoms seen in first-episode patients with schizophrenia when treated with antipsychotic for 1 year. Forty-seven first-episode patients with schizophrenia were scanned at a drug-naive baseline state and followed up for 1 year to identify negative symptom responders (Rn) and non-responders (NRn)...

Cannabinoid hyperemesis syndrome (CHS) is an underrecognized diagnosis among adolescents. In the adult literature, it is characterized as nausea, vomiting, and abdominal pain in patients with chronic marijuana use. CHS is often refractory to the standard treatment of nausea and vomiting. Unconventional antiemetics, such as haloperidol, have been successful in alleviating symptoms; however, even 1 dose of haloperidol can lead to grave adverse effects, such as dystonia, extrapyramidal reactions, and neuroleptic malignant syndrome...

Clozapine is a second-generation antipsychotic typically reserved for refractory psychotic disorders due to its high-risk side effect profile to include agranulocytosis, with its attendant need for regular blood draws. While reports of extrapyramidal symptoms (EPS), including acute dystonic reactions, are exceedingly rare, we present the case of a 44-year-old male with a long-standing history of treatment-resistant schizoaffective disorder and no history of EPS who experienced an acute buccal dystonic reaction in the setting of clozapine initiation and discontinuation of depot and oral risperidone...

Eduard Vieta, José Manuel Montes
Bipolar disorder places a significant burden on the affected individuals, their family, healthcare systems and the overall economy. More treatment options are needed, especially those with better efficacy and tolerability. Asenapine is a second-generation antipsychotic approved in Europe (brand name Sycrest(®)) for the treatment of moderate-to-severe manic episodes associated with bipolar I disorder in adults, and in the US (brand name Saphris(®)) for the treatment of manic or mixed episodes of bipolar I disorder in adults and children aged 10-17 years...

Reports of myelitis associated with human herpesvirus-6 (HHV-6) following allogeneic transplantation are rare. Of 121 cases of cord blood transplantation (CBT) performed at Nagano Red Cross Hospital, five cases (4.1%) of HHV-6 myelitis developed at around the time of engraftment. The major symptom identified in all five patients was superficial pain or pruritus linked to segmental levels of the spinal cord. Other identified symptoms were fever or low-grade fever in all five patients, autonomic nerve disorder in four patients, bladder and rectal disturbance in two patients, and extrapyramidal disorder in two patients...

Sarah Wiethoff, Henry Houlden
Neurodegeneration with brain iron accumulation (NBIA) describes a heterogeneous group of inherited rare clinical and genetic entities. Clinical core symptoms comprise a combination of early-onset dystonia, pyramidal and extrapyramidal signs with ataxia, cognitive decline, behavioral abnormalities, and retinal and axonal neuropathy variably accompanying these core features. Increased nonphysiologic, nonaging-associated brain iron, most pronounced in the basal ganglia, is often termed the unifying characteristic of these clinically variable disorders, though occurrence and extent can be fluctuating or even absent...

RATIONALE: 2-Bromoterguride, a dopamine D2 receptor partial agonist with antagonist properties at serotonin 5-HT2A receptors and α2C-adrenoceptors, meets the prerequisites of a putative atypical antipsychotic drug (APD). We recently showed that 2-bromoterguride is effective in tests of positive symptoms of schizophrenia in rats without inducing extrapyramidal side effects or metabolic changes. OBJECTIVE: In continuation of our recent work, we now investigated the effect of 2-bromoterguride on apomorphine and phencyclidine (PCP)-induced disruptions of prepulse inhibition (PPI) of the acoustic startle response, a measure of sensory gating...

Objectives Morin is a naturally occurring flavonoid with strong anti-oxidant and anti-inflammatory properties. Studies have shown that flavones modulate neurotransmission through enhancement of gamma amino butyric acid activity in the central nervous system; which led to the hypothesis that they could exert tranquilizing effects in rodents. Hence, this study was designed to evaluate the antipsychotic effect of morin on experimental animal models. Methods The antipsychotic effect of morin (25, 50 and 100 mg/kg) administered intraperitoneally (i...
