BACKGROUND: We studied the patient and non-patients factors of inappropriate psychotropic drug (PD) prescription for neuropsychiatric symptoms (NPS) in nursing home patients with severe dementia. METHODS: In a cross-sectional study, the appropriateness of prescriptions was explored using the Appropriate Psychotropic drug use In Dementia (APID) index sum score. This index assesses information from medical records on indication, evaluation, dosage, drug-drug interactions, drug-disease interactions, duplications, and therapy duration...

Fluoxetine (FLX) has broad neurobiological functions and neuroprotective effects; however, the preventive effects of FLX on cognitive impairments in Alzheimer's disease (AD) have not been reported. Here, we studied whether adolescent administration of fluoxetine can prevent memory deficits in AD transgenic mice that harbour PS1m146v, APPswe and TauP301L mutations (3 × TgAD). FLX was applied through peritoneal injection to the mice at postnatal day 35 (p35) for 15 consecutive days, and the effects of FLX were observed at 6-month...

OBJECTIVES: Slow gait has been shown to be a good predictor of declining cognitive function in healthy older adults. Motoric cognitive risk (MCR) syndrome is a new construct incorporating slow gait and subjective cognitive complaints in individuals without dementia who have preserved activities of daily living. This analysis investigated the prevalence of MCR and factors associated with MCR in a nationally representative population. In addition, cross-sectional associations between MCR and cognitive domains, an relationship yet to be fully elucidated in literature, was investigated...

OBJECTIVE: Depression is associated with increased mortality in community samples. The use of antidepressant medication may also increase mortality, however, it is still unclear whether taking antidepressants before or after a diagnosis of dementia influences survival. DESIGN: Retrospective. SETTING: A cohort with a diagnosis of Alzheimer disease (AD) from a large mental health and dementia care database in South London, linked to hospitalization and mortality data...

α2A- and α2C-adrenoceptors (ARs) are the primary α2-AR subtypes involved in central nervous system (CNS) function. These receptors are implicated in the pathophysiology of psychiatric illness, particularly those associated with affective, psychotic, and cognitive symptoms. Indeed, non-selective α2-AR blockade is proposed to contribute toward antidepressant (e.g., mirtazapine) and atypical antipsychotic (e.g., clozapine) drug action. Both α2C- and α2A-AR share autoreceptor functions to exert negative feedback control on noradrenaline (NA) release, with α2C-AR heteroreceptors regulating non-noradrenergic transmission (e...

Correlational and causal comparative research link ceramide (Cer), the precursor of complex sphingolipids, to some psychiatric (e.g., depression, schizophrenia (SZ), alcohol use disorder, and morphine antinociceptive tolerance) and neurological (e.g., Alzheimer's disease (AD), Parkinson disease (PD)) disorders. Cer generation can occur through the de novo synthesis pathway, the sphingomyelinase pathways, and the salvage pathway. The discoveries that plasma Cer concentration increase during depressive episodes in patients and that tricyclic and tetracyclic antidepressants functionally inhibit acid sphingomyelinase (ASM), the enzyme that catalyzes the degradation of sphingomyelin to Cer, have initiated a series of studies on the role of the ASM-Cer system in depressive disorder...

Cissampelos sympodialis Eichl is used in folk medicine for the treatment of various inflammatory diseases; several alkaloids were isolated from this species and some of them have anti-allergic activity, immunomodulatory and spasmolytic. Treatment of rats with the total tertiary alkaloid fraction showed an antidepressant effect. One of the depression causes can be the deficiency of monoamines, which is a factor displayed in patients with Alzheimer's disease. Theoretical studies using in silico methods have aided in the process of drug discovery...

A liquid chromatography-triple quadrupole-tandem mass spectrometry (LC-qQq-MS/MS) method was developed for simultaneous determination of 89 legal neuropsychiatric pharmaceuticals and illicit drugs (both parent compounds and metabolites) and other micropollutants in unfiltered wastewater and freshwater. The target chemicals fall under the classes of amphetamine-type stimulants, cocaine compounds, opiates and opioids, benzodiazepines, lysergic compounds, antipsychotics, anesthetics, antiepileptics, antidepressants, sympathomimetics, cannabinoids, blood thinners, antihistamines, β-blockers, caffeine derivatives, nicotine derivatives, z-drugs, new designer drugs, and Alzheimer medications...

BACKGROUND: Antidepressant use has been associated with an increased risk of falling, but no studies have been conducted on whether antidepressant use is associated with an increased risk of head injuries which often result from falling among older persons. The objective of this study was to investigate the risk of head and brain injuries associated with antidepressant use among community-dwelling persons with Alzheimer's disease. METHODS: A matched cohort study was conducted by comparing new antidepressant users (n = 10,910) with two matched nonusers (n = 21,820) in the MEDALZ study cohort...

Methylene Blue (MB) is considered to have diverse medical applications and is a well-described treatment for methemoglobinemias and ifosfamide-induced encephalopathy. In recent years the focus has shifted to MB as an antimalarial agent and as a potential treatment for neurodegenerative disorders such as Alzheimer's disease. Of interest are reports that MB possesses antidepressant and anxiolytic activity in pre-clinical models and has shown promise in clinical trials for schizophrenia and bipolar disorder. MB is a noteworthy inhibitor of monoamine oxidase A (MAO-A), which is a well-established target for antidepressant action...

BACKGROUND: Asarone is one of the most researched phytochemicals and is mainly present in the Acorus species and Guatteria gaumeri Greenman. In preclinical studies, both α- and β-asarone have been reported to have numerous pharmacological activities and at the same time, many studies have also revealed the toxicity of α- and β-asarone. PURPOSE: The purpose of this comprehensive review is to compile and analyze the information related to the pharmacokinetic, pharmacological, and toxicological studies reported on α- and β-asarone using preclinical in vitro and in vivo models...

BACKGROUND: Mild cognitive impairment (MCI) has been suggested to represent a prodromal stage of dementia and to confer a high risk for conversion to dementia Alzheimer's type (DAT). OBJECTIVES: In this study, we examined the predictive value of depressive symptoms and neuropsychological variables on conversion of MCI to DAT. METHODS: Neuropsychological and clinical follow-up data of 260 MCI patients seen at the Psychiatric Memory Clinic of the Medical University of Innsbruck between 2005 and 2015 were analyzed retrospectively...

Striatal-enriched tyrosine protein phosphatase (STEP) is expressed mainly in the brain. Its dysregulation is associated with Alzheimer's and Huntington's diseases, schizophrenia, fragile X syndrome, drug abuse and stroke/ischemia. However, an association between STEP and depressive disorders is still obscure. The review discusses the theoretical foundations and experimental facts concerning possible relationship between STEP dysregulation and depression risk. STEP dephosphorylates and inactivates several key neuronal signaling proteins such as extracellular signal-regulating kinase 1 and 2 (ERK1/2), stress activated protein kinases p38, the Src family tyrosine kinases Fyn, Pyk2, NMDA and AMPA glutamate receptors...

Alzheimer's disease (AD) is a major and devastating neurodegenerative disease, and the amyloid-β (Aβ) hypothesis is still the central theory for AD pathogenesis. Meanwhile, another major mental illness, depression, is one of the risk factors for AD. From a high-throughput screening (HTS), amoxapine, a typical secondary amine tricyclic antidepressant (TCA), was identified to reduce Aβ production. A follow-up investigation on antidepressants showed that most of the TCAs harbour similar activity. Previous studies have indicated that TCAs improve cognitive function in AD mouse models as well as in preliminary clinical data; however, the underlying mechanism is controversial, and the effect on Aβ is elusive...
