BACKGROUND: Assessment of decisional capacity requires thorough clinical review of a patient's current psychiatric symptoms and cognitive processes. The assessment to determine the patient's capacity for self-management postdischarge is a different clinical concept from decisional capacity. OBJECTIVES: Standardized guidelines for capacity determinations (both for informed consent and for disposition) would be helpful to clinicians, patients, and their caregivers...

Disrupted in schizophrenia 1 (DISC1) is a multi-functional scaffolding protein that has been associated with neuropsychiatric disease. The role of DISC1 is to assemble protein complexes that promote neural development and signaling, hence tight control of the concentration of cellular DISC1 in neurons is vital to brain function. Using structural and biochemical techniques, we show for we believe the first time that not only is DISC1 turnover elicited by the ubiquitin proteasome system (UPS) but that it is orchestrated by the F-Box protein, FBXW7...

Cerebral malaria (CM) is a common cause of death and disability among children in sub-Saharan Africa. Many prior studies of neuropsychiatric morbidity have been limited by a cross-sectional design or a short duration of follow-up. Most have included subjects who may have presented with coma due to a disease process other than CM. No studies have assessed the relationship between magnetic resonance imaging (MRI) findings and long-term outcomes. The Cognitive Outcomes and Psychiatric symptoms of retinopathy-positive CM (COPS) cohort is the first large (N = 221) prospectively recruited cohort of stringently defined cases of CM and hospital-based, age-matched, non-CM controls in whom cognitive and psychiatric outcomes are assessed with standardized measures semi-annually for up to 5 years...

Unilateral subthalamotomy is an effective treatment for the cardinal motor features of Parkinson's disease (PD). However, non-motor changes possibly associated with right or left subthalamotomy remain unknown. Our aim was to assess cognitive, psychiatric and neuroimaging changes after treatment with unilateral subthalamotomy. Fourteen medicated patients with PD were evaluated before and after (mean 6 months after operation) unilateral subthalamotomy (5 right, 9 left). In addition to motor assessments, cognitive (global cognition and executive functions), psychiatric (apathy, depression, anxiety, mania, hypo- and hyperdopaminergic behaviours, impulsivity), quality of life evaluations and volume of lesions were obtained...

In an earlier report, we demonstrated an antipsychotic-like activity of a methanolic extract of Morinda citrifolia Linn fruit in mouse models and postulated the contribution of its bioactive principles, scopoletin and rutin. Moreover, the antidopaminergic activities of scopoletin and rutin were reported in isolated vas deferens preparations. In the present study, scopoletin and rutin were assessed for antipsychotic-like activity using apomorphine-induced climbing behavior and methamphetamine-induced stereotypy in mice...

Acquired hepatocerebral degeneration is a neurological syndrome with typical clinical (extrapyramidal and neuropsychiatric) symptoms and brain magnetic resonance imaging findings (high T1 signal in the globus pallidus). It occurs mainly in patients with advanced liver disease, such as in patients co-infected with hepatitis B virus (HBV) and hepatitis delta virus (HDV). However, there are no reports relating HBV/HDV coinfection and acquired hepatocerebral degeneration. This report presents the case of a 49-year-old woman with characteristics of acquired hepatocerebral degeneration and liver cirrhosis due to HBV/HDV coinfection, and presents the main theories of the physiopathology of this condition...

BACKGROUND AND PURPOSE: Porphyrias are a group of inherited metabolic disorders resulting from a specific deficiency along the pathway of haem biosynthesis. A clinical classification distinguishes acute from non-acute porphyrias considering the occurrence of life-threatening neurovisceral attacks, presenting with abdominal pain, neuropsychiatric disturbance and neuropathy. Vasospasm is a very rare complication that can occur in all major types of acute porphyria. METHODS: We describe a porphyric crisis with vasospasm in a woman with previously undiagnosed acute porphyria...

Brain-derived neurotrophic factor (BDNF) plays a fundamental role in expressing various neural functions including memory consolidation. Alterations of BDNF levels in the brain are associated with neurodegenerative and neuropsychiatric disorders. Therefore, it is important to understand how levels of BDNF are controlled. Recently we generated a novel transgenic mouse strain, termed the Bdnf-Luciferase transgenic (Bdnf-Luc Tg) mouse, to monitor changes in Bdnf expression. In the present study, we detected the bioluminescence signal from living Bdnf-Luc Tg mice after intraperitoneal administration of d-luciferin...

INTRODUCTION: Guillain Barré Syndrome (GBS) is an acute immune-mediated polyneuropathy most frequently presenting two to four weeks after an acute mild-moderately severe infection as progressive muscular weakness of the lower limbs extending proximally with dysreflexia and autonomic dysfunction. While GBS is typically believed to be isolated to the Peripheral Nervous System, Central Nervous System (CNS) and psychiatric manifestations as a sequela of the disease have been described in different imaging and clinical studies...

Acaeruloplasminaemia is a rare neurodegenerative disorder in which dysfunction of the caeruloplasmin gene results in brain iron accumulation alongside systemic iron overload. We discuss the case of a 53-year-old male who presented to neurology with a 4-year history of progressive neuropsychiatric symptoms and was eventually diagnosed with this condition. We discuss the characteristic clinical features and supporting laboratory and radiological findings as well as clinical pointers to help differentiate it from other conditions which might cause diagnostic confusion...

The GERAS study is an international observational study with dementia patients of the Alzheimer type (AD) and their caregivers in everyday care. The 18-month data recorded in Germany are presented. Disease progression, medical and psychosocial consequences for both patients and caregivers were recorded using commonly used tests in clinical care: the mini mental status examination (MMSE), Alzheimer's disease assessment scale (ADAS-Cog14), Alzheimer's disease cooperative study activities of daily living inventory (ADCS-ADL), neuropsychiatric inventory (NPI-12), resource utilization in dementia (RUD) and the Zarit burden interview (ZBI)...

BACKGROUND: Fibroblast growth factors (FGFs) and their receptors (FGFRs) are involved in the development and function of multiple organs and organ systems, including the central nervous system (CNS). FGF signaling via FGFR1, one of the three FGFRs expressed in the CNS, stimulates proliferation of stem cells during prenatal and postnatal neurogenesis and participates in regulating cell-type ratios in many developing regions of the brain. Anomalies in FGFR1 signaling have been implicated in certain neuropsychiatric disorders...

Converging evidence shows that many neuropsychiatric diseases should be understood as disorders of large-scale neuronal networks. To better understand the pathophysiological basis of these diseases, it is necessary to precisely characterize in which way the processing of information is disturbed between the different neuronal parts of the circuit. Using extracellular in vivo electrophysiological recordings, it is possible to accurately delineate neuronal activity within a neuronal network. The application of this method has several advantages over alternative techniques, e...

Decision-making is considered a fundamental aspect of personal autonomy and can be affected in psychiatric and neurologic diseases. It has been shown that cognitive deficits in dementia impact negatively on decision-making. Moreover, studies highlighted impaired clinical competence in neuropsychiatric disorders, such as schizophrenia and bipolar disorder. In this context, the current study explored the relationship between behavioral and psychological symptoms of dementia (BPSD) and clinical competence, especially the capacity to consent to treatment, in Alzheimer's disease (AD)...

Tuberous sclerosis complex is an autosomal dominant inherited disorder characterized by generalized involvement and variable manifestations with a birth incidence of 1:6000. In a quarter of a century, significant progress in tuberous sclerosis complex has been made. Two responsible genes, TSC1 and TSC2, which encode hamartin and tuberin, respectively, were discovered in the 1990s, and their functions were elucidated in the 2000s. Hamartin-Tuberin complex is involved in the phosphoinositide 3-kinase-protein kinase B-mammalian target of rapamycin signal transduction pathway, and suppresses mammalian target of rapamycin complex 1 activity, which is a center for various functions...

Medium spiny neurons (MSNs), the major GABAergic projection neurons in the striatum, are implicated in many neuropsychiatric diseases, such as schizophrenia, but the underlying mechanisms remain unclear. We found that a deficiency in Erbb4, a schizophrenia risk gene, in MSNs of the nucleus accumbens (NAc) core but not the dorsomedial striatum (DMS) markedly induced schizophrenia-like behaviors such as hyperactivity, abnormal marble-burying behavior, damaged social novelty recognition and impaired sensorimotor gating function in male mice...

Wilson's disease is characterised by deposition of copper in various tissues of the body, most markedly in the liver and the brain. Cerebral involvement, evident as neuropsychiatric symptoms, may be the presenting form of the illness in up to 50% of the adults. When patients present initially with psychiatric manifestations, the correct diagnosis is frequently missed. This case report describes an adult in his late 20's who presented with symptoms of major depressive disorder, but failed to respond to standard antidepressant treatment...

RATIONALE: Endogenous γ-aminobutyric acidA receptor (GABAAR)-active neurosteroids (e.g., allopregnanolone) regulate central nervous system excitability and many physiological functions, so fluctuations are implicated in several neuropsychiatric disorders. Pertinently, evidence supports an inverse relationship between endogenous GABAAR-active neurosteroid levels and behavioral changes in excitability during ethanol withdrawal (WD). OBJECTIVES: The present studies determined mouse genotype differences in ten neurosteroid levels in plasma, cortex, and hippocampus over the time course of ethanol WD in the WD Seizure-Prone (WSP) and WD Seizure-Resistant (WSR) selected lines and in the DBA/2J (DBA) inbred strain...
