BACKGROUND: Among the neuropsychiatric complications commonly induced by traumatic brain injury (TBI), behavioral disorders, such as agitation and aggression, can hinder neurological recovery and deteriorate rehabilitation outcomes. Pharmacological treatment for behavioral disorders might be beneficial but could lead to drug-induced parkinsonism. We report a case of a patient with drug-induced parkinsonism manifested as freezing of gait after TBI, which improved with the cessation of the offending drugs and comprehensive rehabilitation...

Study ObjectiveCats may respond to seizures with a threat response (Strong, 1999). Detailed description of this for seizures or pseudoseizures has not heretofore been described. METHOD: Case study: A 29-year-old right handed female, two years prior to presentation, developed onset of seizures which last approximately one minute, almost on a daily basis. These are associated with shortness of breath and postictal blurred vision. During these epoch, she would experience temporary amnesia; a feeling as if she had lost a couple years of memory which gradually returned within an hour...

14-3-3γ plays diverse roles in different aspects of cellular processes. Especially in the brain where 14-3-3γ is enriched, it has been reported to be involved in neurological and psychiatric diseases (e.g. Williams-Beuren syndrome and Creutzfeldt-Jakob disease). However, behavioral abnormalities related to 14-3-3γ deficiency are largely unknown. Here, by using 14-3-3γ deficient mice, we found that homozygous knockout mice were prenatally lethal, and heterozygous mice showed developmental delay relative to wild-type littermate mice...

4-Fluoromethylphenidate (4F-MPH) is an halogenated derivative of methylphenidate (MPH), a re-uptake inhibitor for dopamine and norepinephrine used for the treatment of attention deficit hyperactivity disorders. In the last few years, several compounds structurally related to MPH have been marked as new psychoactive substances (NPS) with stimulating and euphoric effects similar to the parent drug, but with more dopaminergic activity. This report represents the first case of an analytically confirmed non-fatal intoxication by 4F-MPH...

Traumatic brain injury (TBI) is a common risk factor for later neurodegeneration, which can manifest as dementia. Despite this, little is known about the time-course of development of functional deficits, particularly cognitive and neuropsychiatric impairments, and whether these differ depending on the nature of the initiating insult. Therefore, this study investigated long term functional impairment at 12 months post-injury following diffuse TBI of different severities. Male Sprague-Dawley rats (420-480 g; 10-12 weeks) were either given a sham surgery (n = 14) or subjected to Marmarou's impact acceleration model of diffuse TBI for a single mild TBI (n = 12), repetitive mild TBI (3 mild diffuse injuries at 5 day intervals) (n = 14) or moderate to severe TBI (n = 14)...

Mammalian target of rapamycin (mTOR) is a central regulator of cellular metabolism. The importance of mTORC1 signaling in neuronal development and functions has been highlighted by its strong relationship with many neurological and neuropsychiatric diseases. Previous studies demonstrated that hyperactivation of mTORC1 in forebrain recapitulates tuberous sclerosis and neurodegeneration. In the mouse cerebellum, Purkinje cell-specific knockout of Tsc1/2 has been implicated in autistic-like behaviors. However, since TSC1/2 activity does not always correlate with clinical manifestations as evident in some cases of tuberous sclerosis, the intriguing possibility is raised that phenotypes observed in Tsc1/2 knockout mice cannot be attributable solely to mTORC1 hyperactivation...

Genomic copy number variants (CNVs) are amongst the most highly penetrant genetic risk factors for neuropsychiatric disorders. The scarcity of carriers of individual CNVs and their phenotypical heterogeneity limits investigations of the associated neural mechanisms and endophenotypes. We applied a novel design based on CNV penetrance for schizophrenia (Sz) and developmental delay (DD) that allows us to identify structural sequelae that are most relevant to neuropsychiatric disorders. Our focus on brain structural abnormalities was based on the hypothesis that convergent mechanisms contributing to neurodevelopmental disorders would likely manifest in the macro- and microstructure of white matter and cortical and subcortical grey matter...

Neurodegeneration with brain iron accumulation is a broad term that describes a heterogeneous group of progressive and invalidating neurologic disorders in which iron deposits in certain brain areas, mainly the basal ganglia. The predominant clinical symptoms include spasticity, progressive dystonia, Parkinson's disease-like symptoms, neuropsychiatric alterations, and retinal degeneration. Among the neurodegeneration with brain iron accumulation disorders, the most frequent subtype is pantothenate kinase-associated neurodegeneration (PKAN) caused by defects in the gene encoding the enzyme pantothenate kinase 2 (PANK2) which catalyzed the first reaction of the coenzyme A biosynthesis pathway...

Wilson's disease (WD), in contrast to many neurogenetic metabolic diseases, can be very effectively treated in acute and chronic stages of the disease. However, early recognition is paramount because delays in treatments have much higher risk of unfavorable clinical outcomes. Identification of WD remains challenging because it is a great imitator and requires a high index of suspicion for correct and timely diagnosis. Initial neurologic problems can be seen in approximately 40%-50% of patients and the rest has either hepatic or primarily psychiatric manifestations...

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that can involve nervous system commitment known as neuropsychiatric systemic lupus erythematosus (NPSLE). The diagnostic of NPSLE is complex because the symptoms range from focal symptoms (e.g., strokes, thrombotic events) to diffuse disorders affecting cognition, mood and level of consciousness (e.g. acute confusional state, psychosis). Both type of manifestations of NPSLE differ in their pathological mechanisms. The focus of this review will be on the mechanisms that lead to the blood-brain barrier (BBB) disruption and to the neuroinflammation related with the diffuse manifestations of NPSLE...

Selecting appropriate animal models for a particular human phenomenon is a difficult but important challenge. The difficulty lies in finding animal behaviors that are not only sufficiently relevant and analog to the complex human symptoms (face validity) but also have similar underlying biological and etiological mechanisms (translational or construct validity), and have "human-like" responses to treatment (predictive validity). Over the past several years, the domestic dog (Canis familiaris) has become increasingly proposed as a model for comparative and translational neuroscience...

Research in the past two decades has revolutionized our understanding of depressive illnesses. Proinflammatory cytokines have become a point of interest in the interconnecting areas of neuropsychiatric and autoimmune diseases. The cytokine hypothesis of depression suggests that pro-inflammatory cytokines play a primary role in the mediation of the pathophysiological characteristics of major depression, in which an inflammatory process may be induced by external and internal stressors such as psychological and inflammatory diseases, respectively...

The neuropsychiatric symptoms of multiple sclerosis (MS), such as anxiety and depression, can result from disease activity itself as well as psychological reaction to an unfavorable diagnosis. Accordingly, the literature reports evidence of increased anxiety-like behavior in experimental autoimmune encephalomyelitis (EAE), an accepted MS model. Due to the recently described critical role of platelets in inflammation and autoimmune disease, we examined the relationship between platelets, inflammation, and anxiety-like behavior in EAE...
