Models of poststroke depression and assessments of core depressive symptoms in rodents: How to choose?

Models of poststroke depression and assessments of core depressive symptoms in rodents: How to choose? Exp Neurol. 2019 Sep 07;:113060 Authors: Tao X, Yang W, Zhu S, Que R, Liu C, Fan T, Wang J, Mo D, Zhang Z, Tan J, Jin K, Yenarih MA, Song T, Wang Q Abstract Our previous studies have indicated that depression and declined cognition have been involved in some neurodegenerative diseases including Stroke, Parkinson's diseases and Vascular Parkinsonism. Post-stroke depression (PSD) is the most common psychiatric disorder following a stroke and has high morbidity and mortality. Studies on PSD are increasingly common, but the specific mechanisms remain unknown. Current research mainly includes clinical and animal aspects. Questionnaires and peripheral blood examination are two of the most common methods used to study clinical PSD. The results of questionnaires are influenced by multiple factors such as disease history, education background, occupation, economic status, family relationships and social support. There are certain limitations to blood sample testing; for example, it is influenced by cerebrovascular diseases and some other disruptions of the internal environment. It is difficult for either method to fully clarify the pathophysiological mechanism of PSD. Animal models provide alternative methods to further understand the pathophysiological mechanisms of PSD, such as the involvement of neuronal circuits and cytokines. More than ten animal models of ...

Authors: Amieva H, Meillon C, Proust-Lima C, Dartigues JF Abstract BACKGROUND: Dementia, stroke, depression, and disability are frequent in late life and are major causes of quality of life disruption and family burden. Even though each of these disorders relies on specific pathogenic processes, a common clinical manifestation is psychomotor slowing. OBJECTIVE: We assessed the relevance of a simple marker of low psychomotor speed in predicting several brain outcomes: dementia, Alzheimer's disease (AD), Parkinson's disease (PD), stroke, depressive symptoms, and disability in activities of daily living (ADL) and ...

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...

Bing Wang As our global population ages, the treatment of neurodegenerative diseases is critical to our society. In recent years, researchers have begun to study the role of biologically active chemicals from plants and herbs to gain new inspiration and develop new therapeutic drugs. Ginseng (Panax ginseng C.A. Mey.) is a famous Chinese herbal medicine with a variety of pharmacological activities. It has been used to treat various diseases since ancient times. Extensive research over the years has shown that ginseng has potential as a neuroprotective drug, and its neuroprotective effects can be used to treat and preven...

Abstract The pituitary adenylate cyclase-activating polypeptide (PACAP)-selective PAC1 receptor (PAC1R, ADCYAP1R1) is a member of the vasoactive intestinal peptide (VIP)/secretin/glucagon family of G protein-coupled receptors (GPCRs). PAC1R has been shown to play crucial roles in the central and peripheral nervous systems. The activation of PAC1R initiates diverse downstream signal transduction pathways, including adenylyl cyclase, phospholipase C, MEK/ERK and Akt pathways that regulate a number of physiological systems to maintain functional homeostasis. Accordingly, at times of tissue injury or insult, PACAP/PAC...

, Molnár B Abstract Vitamin B9, also known as folate, can be found in natural and synthetic forms, mostly in vegetables or folic acid containing food supplements. By participating in the proper cell development and division, its presence is indispensable for certain basic metabolic processes. The decreased folate level of the body, mainly caused by environmental and hereditary factors as well as aging, can lead to genetic, epigenetic and metabolic changes. It can be related to the development of megaloblastic anemia, various cardiovascular diseases (such as atherosclerosis, stroke) obstetrical complications...

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...

This study sought to investigate what could be learned from how these men have fared. The men were born in 1925-1928 and similar health-related data from questionnaires, physical examination, and blood samples are available for all surveys. Survival curves over various variable strata were applied to evaluate the impact of individual risk factors and combinations of risk factors on all-cause deaths. At the end of 2018, 118 (16.0%) of the men had reached 90 years of age. Smoking in 1974 was the strongest single risk factor associated with survival, with observed percentages of men reaching 90 years being 26.3, 25.7, ...

Cotard delusion is a nihilistic delusion that presents as denial of self-existence and is a rare neuropsychiatric phenomenon associated with diverse neurologic or psychiatric disorders [1]. Various case reports and case series have indicated associations between Cotard delusion and neurologic or psychiatric diseases; these include depression, schizophrenia, traumatic brain injury, multiple sclerosis, stroke, and Parkinson ’s disease [1]. However, there have been few reports of Cotard delusion in epilepsy patients [2].

AbstractCurcumin is widely consumed in Asia either as turmeric directly or as one of the culinary ingredients in food recipes. The benefits of curcumin in different organ systems have been reported extensively in several neurological diseases and cancer. Curcumin has got its global recognition because of its strong antioxidant, anti ‐inflammatory, anti‐cancer, and antimicrobial activities. Additionally, it is used in diabetes and arthritis as well as in hepatic, renal, and cardiovascular diseases. Recently, there is growing attention on usage of curcumin to prevent or delay the onset of neurodegenerative diseases. This...
