Background: Very little is known about the relationship between spontaneous and treatment-induced motor syndromes in Africans with first episode schizophrenia. Objective: We investigated the association between spontaneous NSS and EPS, with treatment-induced EPS in a homogenous sample of Black Africans with first episode schizophrenia. Methods: We examined Xhosa (South Africa) and Yoruba (Nigeria) patients, using the Neurological Evaluation Scale and extrapyramidal symptoms scale before and at 3 months after exposure to low dose flupenthixol decanoate...

Antipsychotics have long been the mainstay of treatment for agitation and psychosis in Alzheimer's disease. Despite their current use successive studies have shown that they only confer a modest benefit which must be balanced against their well-established serious side effects (extrapyramidal symptoms, stroke, accelerated cognitive decline and mortality). Areas covered: This review outlines the current guidance on antipsychotic usage and the evidence of their continued usage against a backdrop of emerging pharmacological treatments and an increasing emphasis on the importance of non-pharmacological interventions...

The clinical assessment of Parkinson's disease (PD) symptoms is typically performed with neurological examinations and simple motor tests. However, this only takes into account the severity of motor symptoms during the length of the recording and fails to capture variations in a patient's motor state, which change continuously during the day. Most of the current methods for long-term monitoring of extrapyramidal symptoms are based on the use of a wearable magneto-inertial device that evaluates the frequential content of signals in the range of movement disorders...

MICU1 encodes a Ca2+ sensing, regulatory subunit of the mitochondrial uniporter, a selective calcium channel within the organelle's inner membrane. Ca2+ entry into mitochondria helps to buffer cytosolic Ca2+ transients and also activates ATP production within the organelle. Mutations in MICU1 have previously been reported in 17 children from nine families with muscle weakness, fatigue, normal lactate, and persistently elevated creatine kinase, as well as variable features that include progressive extrapyramidal signs, learning disabilities, nystagmus, and cataracts...

The monoamine stabilizer (3S)-3-[3-(methenesulfonyl)phenyl]-1-propylpiperidine hidrochloride [(-)-OSU6162] is a promising compound for the treatment of neurological and psychiatric disorders, such as schizophrenia. Here, we tested the hypothesis that (-)-OSU6162 prevents hyperlocomotion and sensorimotor deficits in prepulse inhibition of the startle response (PPI) induced by psychomimetic drugs. Male Swiss mice received injections of (-)-OSU6162 (1, 3, 10, or 30 mg/kg), and their motor responses were investigated in the open field and in the catalepsy tests, which predicts liability to induce sedation and extrapyramidal side effects, respectively...

Angioedema has recently been reported as a side effect associated with the antipsychotic risperidone. We report a case of dystonia with concurrent angioedema due to risperidone. A 40-year-old male with a history of schizophrenia was started on 3 mg of risperidone BID and developed perioral and periorbital edema along with increased muscle rigidity and hand tremor within 24 h of initial administration. His symptoms abated after cessation of risperidone and intravenous administration of corticosteroids and antihistamine...

Akathisia is a common and distressing neuropsychiatric syndrome associated with antipsychotic medication, characterised by subjective and objective psychomotor restlessness. The goal of this guideline is to provide clinicians with recommendations on the assessment and treatment of akathisia. We performed a systematic review of therapeutic studies assessing the treatment of antipsychotic-induced extrapyramidal symptoms. Forty studies on akathisia and 4 systematic reviews evaluating the adverse effects of antipsychotics were used in the formulation of recommendations...

A decrease in somatostatin activity is observed in the Parkinsonian brain. In recent experiments on rats, we simulated this abnormality by intracerebroventricular injections of a somatostatin antagonist, cyclosomatostatin. The treated animals displayed catalepsy, a state that resembles the extrapyramidal signs of Parkinson's disease. The neuroanatomical substrates mediating the catalepsy-inducing effect of cyclosomatostatin are unknown. To clarify this issue, we assessed here the action of cyclosomatostatin injected into the substantia nigra pars compacta (SNc), dorsal striatum (DS), locus coeruleus (LC), pedunculopontine tegmental nucleus (PPTg), and inferior colliculus (IC)...

BACKGROUND: Hepatic encephalopathy may manifest by a wide spectrum of neuropsychiatric symptoms, including cognitive impairment, seizures or extrapyramidal symptoms. The liver transplant can lead to improvement of the signs of encephalopathy but subsequent immunosuppressive treatment might possess pronounced neurotoxicity. CASE PRESENTATION: We present a case report of a patient with chronic liver disease who developed signs of Parkinsonism after an orthotopic liver transplant, with consecutive immunosuppressant treatment with tacrolimus...

Depression is common in patients with schizophrenia and associated with serious consequences. However, previous studies have mixed findings on characteristics of depression in schizophrenia, partly because of the use of depressive symptom scales that are not specific to schizophrenia. This study examined the prevalence and correlates of depressive symptoms in Chinese patients with schizophrenia. A consecutive sample of 349 male inpatients with schizophrenia was recruited from the largest psychiatric specialty hospital in south-central China...

Nutritional deficiencies related neurological manifestations are not uncommon in infants and children. Here, we describe an infant with Vitamin B12 deficiency due to depleted maternal Vitamin B12 status presenting with progressive encephalopathy and extrapyramidal signs. Diagnosis of infantile tremor syndrome was established in our patient based on the clinical and biochemical parameters. Magnetic resonance imaging had shown frontotemporal atrophy with widened Sylvian fissures and prominent cerebrospinal fluid spaces...

Background: Clozapine is the antipsychotic of choice for treatment-resistant schizophrenia and has minimal risk for extrapyramidal symptoms. Therapeutic benefits, however, are accompanied by a myriad of cardiometabolic side-effects. The specific reasons for clozapine's high propensity to cause adverse cardiometabolic events remain unknown, but it is believed that autonomic dysfunction may play a role in many of these. Objective: This systematic review summarizes the literature on autonomic dysfunction and related cardiovascular side effects associated with clozapine treatment...

Although recent studies focused on traditional Chinese medicine (TCM) for the treatment of refractory schizophrenia have reported that it may be beneficial, there is still lack of convincing evidence and critical meta-analytic work regarding its effectiveness as an adjunctive therapy. Therefore, we performed a meta-analysis to investigate the effectiveness of TCM in combination with antipsychotics for refractory schizophrenia. Fourteen articles involving 1725 patients published as of December 2016 were included which compared antipsychotic therapies to either TCM alone, or TCM as an adjunctive therapy...

OBJECTIVE: Neurological recovery after stroke mainly depends on the location of the lesion. A substantial portion of strokes affects the brainstem. However, patterns of neural plasticity following brainstem ischemia are almost unknown. METHODS: Here, we established a rat brainstem ischemia model that resembles key features of the human disease and investigated mechanisms of neural plasticity including neurogenesis and axonal sprouting as well as secondary neurodegeneration...

Previous research indicates that the subchronic administration of NG-nitro-L-arginine (L-NOARG) produces tolerance to haloperidol-induced catalepsy in Swiss mice. The present study aimed to further investigate whether intermittent subchronic systemic administration of L-NOARG induces tolerance to the cataleptic effects of haloperidol as well as olanzapine or clozapine (Clz) in C57Bl mice after subchronic administration for 5 consecutive days. Striatal FosB protein expression was measured in an attempt to gain further insights into striatal mechanisms in antipsychotic-induced extrapyramidal symptoms side effects...

REVIEW
Ewa Galaj, Scott Ewing, Robert Ranaldi
In the search for efficacious pharmacotherapies to treat cocaine addiction much attention has been given to agents targeting dopamine D1 or D3 receptors because of the involvement of these receptors in drug-related behaviors. D1-like and D3 receptor partial agonists and antagonists have been shown to reduce drug reward, reinstatement of drug seeking and conditioned place preference (CPP) in rodents and non-human primates. However, translation of these encouraging results to clinical settings has been limited due to a number of factors including toxicity, poor pharmacokinetic properties and extrapyramidal and sedative side effects...

BACKGROUND Woodhouse-Sakati syndrome (WSS) is a rare autosomal recessive genetic condition that was first described in 1983. Since its original description, approximately 50 cases have been reported with various clinical signs and symptoms. Characteristics include progressive neurologic deterioration with extrapyramidal involvement and polyendocrinopathy most notable for hypogonadism starting in early adolescence. Clinical presentation is variable, and a subset of patients may have additional features, such as premature aging, alopecia, distinctive facial features, cognitive impairment, or deafness...

Parkinson's disease (PD) is a progressive neurodegenerative motor disorder characterized by the degeneration of dopaminergic nigrostriatal neurons. Levodopa (L-DOPA) is the most effective therapy for PD, however, PD progression continues with significant side effects in long term, thus necessitating the search for effective therapy that impedes PD progression. PD therapy through non-dopaminergic pathways offers treatment without the risk of extrapyramidal effects. In this regard, earlier, we had reported, a novel compound IDPU with potential adenosine A2A receptor antagonist effect in haloperidol (chronic treatment) induced Parkinson model...
