Thought disorder in atypical schizophrenia-like psychosis after stroke: analysis of clinical cases.

We described two cases of female patients, who developed an atypical schizophrenia-like psychosis post-stroke, characterized by formal thought disorder, hallucinations, and delusion. Cerebrovascular disease affected the right temporal lobe, areas devoted to modulation of higher order cognitive processes. To date, the relation between stroke and psychosis remain unclear, maybe due to the involvement of a complex brain networks. However, the high impact of this disorder on physical, psychological and social wellbeing suggests the importance of improving specific treatments. PMID: 31138024 [PubMed - as supplied by publisher]

Publication date: Available online 12 November 2019Source: Progress in NeurobiologyAuthor(s): Joseph H. Neale, Tatsuo YamamotoAbstractN-Acetylaspartylglutamate (NAAG) is the third most prevalent neurotransmitter in the mammalian nervous system, yet its therapeutic potential is only now being fully recognized. Drugs that inhibit the inactivation of NAAG by glutamate carboxypeptidase II (GCPII) increase its extracellular concentration and its activation of its receptor, mGluR3. These drugs warrant attention, as they are effective in animal models of several clinical disorders including stroke, traumatic brain injury and schi...

Our world has never witnessed a time of greater promise for improving human health. Many of today’s health advances have stemmed from a long arc of discovery that begins with strong, steady support for basic science. In large part because of fundamental research funded by the National Institutes of Health (NIH), which traces its roots to 1887, Americans are living longer, healthier lives. Life expectancy for a baby born in the U.S. has risen from 47 years in 1900 to more than 78 years today. Among the advances that have helped to make this possible are a 70% decline in the U.S. death rate from cardiovascular disease ...

We read with great interest the recent letter sent to you by McConnell and colleagues [1], in which they discuss one of the first applications of truly independent home-based electrical brain stimulation, applied following safety recommendations. Transcranial direct-current stimulation (tDCS) is a non-invasive brain stimulation technique capable of modulating cortical excitability beyond the stimulation period [2,3]. tDCS presents interesting options as a therapeutic intervention in multiple neurological disorders, such as stroke, depression, chronic pain, schizophrenia, and Alzheimer ’s and Parkinson’s disease [4,5].

This study comprehensively reviews brain-impaired patients: The studies involving patient populations and the diseases discussed in more than 10 works are included. Eleven diseases examined in this paper include autism spectrum disorder, attention-deficit hyperactivity disorder, epilepsy, depressive disorders, anxiety and panic disorder, schizophrenia, mild cognitive impairment, Alzheimer ’s disease, Parkinson’s disease, stroke, and traumatic brain injury. For each disease, the tasks used for examination, fNIRS variables, and significant findings on the impairment are discussed. The channel configurations and t...

Abstract BACKGROUND: Gray matter (GM) imaging is important in the investigation of many neurological diseases, including schizophrenia, multiple sclerosis, stroke, Alzheimer's disease, tuberous sclerosis, and epilepsy, which are all associated with changes in cortical GM. OBJECTIVE: The aim of this study was to develop a quantitative statistical analysis system for double inversion recovery (DIR) MRI and to evaluate the new system using preliminary clinical data. METHODS: The study population comprised of 10 healthy volunteers and six patients with or without brain degeneration. A quantitative statistica...

Preoperative and postoperative mental health status (MHS) of total joint arthroplasty patients can affect immediate and long-term outcomes following surgery. Alterations in MHS can be acute or chronic. The most common etiologies include acute changes due to (1) delirium or stroke, (2) movement disorders (Alzheimer dementia, Parkinson disease, multiple sclerosis, epilepsy), and (3) mood/behavior disorders (major depressive disorder, anxiety, bipolar disorder, schizophrenia). Across etiologies, alterations in MHS are associated with worse clinical/patient-reported outcomes and greater total cost of care. Prevention via pharm...

Mitral valve prolapse (MVP), which occurs when the valve between the left upper and lower chambers of the heart does not close properly, is significantly more common in patients with panic disorder/agoraphobia, according to ameta-analysis inPsychosomatics (The Journal of Consultation-Liaison Psychiatry). The findings confirm longstanding speculation that the two conditions are linked."This highlights the need of a careful cardiac examination in patients with [panic disorder], many of which also suffer from MVP, ” wrote Umit Tural, M.D., and Dan V. Iosifescu, M.D., M.Sc., of The Nathan S. Kline Institute for Psyc...

ConclusionSchizophrenia and ONOP are the only SMI subtypes associated with adverse clinical outcomes after AMI. However, all patients with SMI were less likely to receive invasive management for AMI, with female gender and schizophrenia diagnosis being the strongest predictors of conservative management. A multidisciplinary approach between psychiatrists and cardiologists could improve the outcomes of this high-risk population.RésuméContexteLe trouble mental grave (TMG) est associé à une augmentation de la mortalité cardiovasculaire. Nous avons étudié la prévalence de...

Abstract 5-HT3 receptor antagonists, first introduced to the market in the mid-1980s, are proven efficient agents to counteract chemotherapy-induced emesis. Nonetheless, recent investigations have shed light on unappreciated dimensions of this class of compounds in conditions with an immunoinflammatory component as well as in neurologic and psychiatric disorders. The promising findings from multiple studies have unveiled several beneficial effects of these compounds in multiple sclerosis, stroke, Alzheimer disease, and Parkinson disease. Reports continue to uncover important roles for 5-HT3 receptors in the physio...

Authors: Carota A, Bogousslavsky J Abstract Hallucinations, delusions, and confabulations are common symptoms between neurology and psychiatry. The neurological diseases manifesting with such symptoms (dementia, epilepsy, Korsakoff's disease, brain tumors, Parkinson's disease, migraine, right hemisphere stroke and others) would be the key to understand their biological mechanisms, while the cognitive sciences, neuropharmacology and functional neuroimaging would be the tools of such researches. It is possible to understand the perceptive rules of the mind and the mechanisms of the human consciousness based on these ...
