The treatment of schizophrenia is challenging due to the wide range of symptoms (positive, negative, cognitive) associated with the disease. Typical antipsychotics that antagonize D2 receptors are effective in treating positive symptoms, but extrapyramidal side-effects (EPS) are a common occurrence. Atypical antipsychotics targeting 5-TH2A and D2 receptors are more effective at treating cognitive and negative symptoms compared to typical antipsychotics, but these drugs also result in side-effects such as metabolic syndromes...

BACKGROUND: Glutaric acidemia Type 1 (GA-1) is an autosomal recessively inherited metabolic disorder which is associated with GCDH gene mutations which alters the glutaryl-CoA dehydrogenase, an enzyme playing role in the catabolic pathways of the amino acids lysine, hydroxylysine, and tryptophan. Clinical findings are often encephalopathic crises, dystonia, and extrapyramidal symptoms. CASE REPORT: A 9-month-old male infant referred to our department with focal tonic-clonic seizures during rotavirus infection and acute infarcts in MRI...

Aripiprazole was the first antipsychotic developed to possess agonist properties at dopamine D2 autoreceptors, a groundbreaking strategy that presented a new vista for schizophrenia drug discovery. The dopamine D2 receptor is the crucial target of all extant antipsychotics, and all developed prior to aripiprazole were D2 receptor antagonists. Extensive blockade of these receptors, however, typically produces extrapyramidal (movement) side effects, which plagued first-generation antipsychotics, such as haloperidol...

REVIEW

Available evidence suggests that second-generation atypical antipsychotics are broadly similar to first-generation agents in terms of their efficacy, but may have a more favourable tolerability profile, primarily by being less likely to cause extrapyramidal symptoms. However, atypical antipsychotics are variably associated with disturbances in the cardiometabolic arena, including increased body weight and the development of metabolic syndrome, which may reflect differences in their receptor binding profiles...

Aripiprazole has been reported to exert variable effects on cognitive function in patients with schizophrenia. Therefore, in the present study, we evaluated biological markers, clinical data, and psychiatric symptoms in order to identify factors that influence cognitive function in patients with schizophrenia undergoing aripiprazole treatment. We evaluated cognitive function in 51 patients with schizophrenia using Brief Assessment of Cognition in Schizophrenia (BACS), as well as background information, psychiatric symptoms, plasma catecholamine metabolites-homovanillic acid (HVA), 3-methoxy-4-hydroxyphenylglycol (MHPG)-, and serum brain-derived neurotrophic factor (BDNF)...

Anti-NMDAR (N-methyl-D-aspartic acid receptor) encephalitis, first described in 2007, is a rare, autoimmune limbic encephalitis. In half of the cases anti-NMDAR antibodies are paraneoplastic manifestations of an underlying tumor (mostly ovarian teratoma). In the early stage of the disease psychiatric symptoms are prominent, therefore 60-70% of the patients are first treated in a psychiatric department. In most of the cases, typical neurological symptoms appear later. Besides the clinical picture and typical symptoms, verifying presence of IgG antibodies in the serum or CSF is necessary to set up the diagnosis...

Creutzfeldt-Jakob disease (CJD) is a rare syndrome of central nervous system caused by infectious protein called prion. There are four types of CJD: sporadic (sCJD), familial (fCJD), jatrogenic (jCJD) and variant (vCJD). The most frequent symptoms are rapidly progressing dementia, mioclonias, akinetic mutism and signs of cerebellum dysfunction. In sCJD, MRI often shows high signal intensity in the putamen and caudate nucleus on T2-weighted images while in vCJD pulvinar sign is often observed. 70% patients with CJD often has characteristic generalized periodic sharp wave pattern in electroencephalography...

BACKGROUND: Mitochondrial acetoacetyl-CoA thiolase (T2) deficiency affects ketone body and isoleucine catabolism. Neurological impairment may occur secondary to ketoacidotic episodes. However, we observed neuromotor abnormalities without ketoacidotic events in two T2-deficient families. We hypothesized that the neurological signs were related to the genetic defect and may occur independently of ketoacidotic episodes. We therefore conducted a retrospective review on a French T2-deficient patient series searching for neuromotor impairment...

BACKGROUND: The negative symptoms of schizophrenia are generally harder to recognize, more difficult to treat than positive symptoms, and have a significant impact on patient functioning and overall outcomes. Treatment with aripiprazole may be associated with benefits on negative symptoms and functioning given its partial agonism to the dopamine D2 receptor. The aim of this subanalysis was to explore the impact of flexibly dosed, long-acting paliperidone palmitate once monthly (PP1M) on negative and depressive symptoms, disorganized thoughts, anxiety, extrapyramidal symptoms, and patient functioning in nonacute adult patients with schizophrenia previously unsuccessfully treated with oral aripiprazole monotherapy...

To address whether wait discontinuation (i.e., introducing the new antipsychotic while maintaining the first for a period before initiating its discontinuation) is superior to non-wait discontinuation (i.e., initiating the first antipsychotic's discontinuation when introducing the new antipsychotic) in antipsychotic switching, we conducted a meta-analysis of randomized controlled trials comparing gradual vs. wait-and-gradual antipsychotic discontinuation in patients with schizophrenia. The meta-analysis of 5 studies (n=410) demonstrated no significant differences in any clinical outcomes, including study discontinuation, psychopathology, extrapyramidal symptoms, and treatment-emergent adverse events, between the two groups...
