GSK3β is a serine threonine kinase implicated in the progression of Alzheimer's disease. Although the role of GSK3β in growth and pathology has been extensively studied, little is known about the metabolic consequences of GSK3β manipulation, particularly in the brain. Here, we show that GSK3β regulates mitochondrial energy metabolism in human H4 neuroglioma cells and rat PC12-derived neuronal cells and that inhibition of GSK3β in mice in vivo alters metabolism in the hippocampus in a region-specific manner...

Misfolding and aggregation of the neuronal, microtubule associated protein tau is involved in the pathogenesis of Alzheimer's disease and tauopathies. It has been proposed that neuronal membranes could play a role in tau release, internalization and aggregation, and that tau aggregates could exert toxicity via membrane permeabilization. Whether and how tau interacts with lipid membranes remains a matter of discussion. Here, we characterize the interaction of full-length human tau (htau40) with supported lipid membranes (SLMs) made from brain total lipid extract by time-lapse high-resolution atomic force microscopy (AFM)...

Telomere length (TL) is a biomarker of cell aging, and its shortening has been linked to several age-related diseases. In Alzheimer's disease (AD), telomere shortening has been associated with neuroinflammation and oxidative stress. The majority of studies on TL in AD were based on leucocyte DNA, with little information about its status in the central nervous system. In addition to other neuroprotective effects, lithium has been implicated in the maintenance of TL. The present study aims to determine the effect of chronic lithium treatment on TL in different regions of the mouse brain, using a triple-transgenic mouse model (3xTg-AD)...

Glucagon-like peptide-1(GLP-1) is a growth factor that has neuroprotective and anti-inflammatory properties. The protease resistant GLP-1 analogue liraglutide has been shown to be neuroprotective in previous studies in animal models of Alzheimer's disease or Parkinson's disease. Status epilepticus (SE) is a complex disorder, involving many underlying pathological processes, including excitotoxic and chronic inflammatory events. The present pilot study aims to investigate whether liraglutide alleviates the chronic inflammation response and mitochondrial stress induced by SE in the lithium-pilocarpine animal model...

Epidemiological evidence suggests that people with bipolar disorder prescribed lithium exhibit a lower risk of Alzheimer's disease (AD) relative to those prescribed other mood-stabilizing medicines. Lithium chloride (LiCl) reduces brain β-amyloid (Aβ) levels, and the brain clearance of Aβ is reduced in AD. Therefore, the purpose of this study was to assess whether the cognitive benefits of LiCl are associated with enhanced brain clearance of exogenously-administered Aβ. The brain clearance of intracerebroventricularly (icv) administered125 I-Aβ42 was assessed in male Swiss outbred mice administered daily oral NaCl or LiCl (300 mg/kg for 21 days)...

OBJECTIVE: No cure is currently available for dementia; however, various treatments and interventions have been reported to be effective. The factors influencing the efficacy of dementia treatment have not been comprehensively evaluated. This study evaluated the factors influencing treatment effects on cognitive dysfunction in dementia by comparing the results obtained from a meta-analysis based on meta-regression. METHODS: We searched for articles, clinical trials, and meta-analyses on the efficacy of pharmacotherapy or psychosocial treatment for dementia published between 2000 and 2016 in the MEDLINE/PubMed, Cochrane Library, SCOPUS, and Airiti Library databases...

Glycogen synthase kinase 3β (GSK3β) is a highly conserved serine/threonine kinase that has been implicated in both psychiatric and neurodegenerative diseases including schizophrenia, bipolar disorder, and Alzheimer's disease; therefore regulating its activity has become an important strategy for treatment of cognitive impairments in these disorders. This study examines the effects of lithium on GSK3β and its interaction with β-catenin and NMDA receptors within the prefrontal cortex. Lithium, a clinically relevant drug commonly prescribed as a mood stabilizer for psychiatric disorders, significantly increased levels of phosphorylated GSK3β serine 9, an inhibitory phosphorylation site, and decreased β-catenin ser33/37/thr41 phosphorylation in vitro , indicating GSK3β inhibition and reduced β-catenin degradation...

Lithium is used as a first line treatment in bipolar disorder. The neuroprotective effects of lithium in this indication tend to be well known and are mediated by its action on two enzymes: glycogen synthase kinase-3 and inositol monophosphatase-1. Preclinical and clinical studies seek to evaluate the neuroprotective effect of lithium in neurodegenerative disorders. The aims of this literature review is to gather clinical studies that investigated the efficacy of lithium in neurodegenerative diseases, using a systematic method based on PubMed data...

BACKGROUND: Alzheimer's disease (AD) mortality rates have steadily increased over time. Lithium, the current gold standard treatment for bipolar disorder, can exert neuroprotective effects against AD. OBJECTIVE: We examined the relationship between trace levels of lithium in drinking water and changes in AD mortality across several Texas counties. METHODS: 6,180 water samples from public wells since 2007 were obtained and averaged for 234 of 254 Texas counties...

OBJECTIVE: Acute seizures induced dendritic formation and synaptogenesis promotes aberrant circuitry development and further aggravates underlying conditions towards chronic epilepsy. The G protein-coupled receptor kinase-5 (GRK5) served as a key modulator in neurogenesis and the establishment of functional neuronal circuitry. This included dendritic development, as its dysfunction could cause different central nervous system disorders, including Alzheimer's disease. However, the involvement of GRK5 in the progression of epilepsy remains unclear...

Metal ions are critical to a wide range of biological processes. Among them, lithium (Li) has been recognised for its benefit as a treatment for bipolar disorder (BD). However, we are yet to grasp the extent of its role in biological processes, despite its molecular targets having been extensively studied. Here we review a wide range of transcriptomic, proteomic and metabolomic studies in order to obtain a full picture of Li effects at various levels. Multifarious patterns of Li-regulated genes, proteins and metabolites are identified...

Importance: Results from animal and human studies suggest that lithium in therapeutic doses may improve learning and memory and modify the risk of developing dementia. Additional preliminary studies suggest that subtherapeutic levels, including microlevels of lithium, may influence human cognition. Objective: To investigate whether the incidence of dementia in the general population covaries with long-term exposure to microlevels of lithium in drinking water. Design, Setting, and Participants: This Danish nationwide, population-based, nested case-control study examined longitudinal, individual geographic data on municipality of residence and data from drinking water measurements combined with time-specific data from all patients aged 50 to 90 years with a hospital contact with a diagnosis of dementia from January 1, 1970, through December 31, 2013, and 10 age- and sex-matched control individuals from the Danish population...

Lithium is first-line therapy for bipolar affective disorder and has recently been shown to have protective effects in populations at risk for Alzheimer's disease (AD). However, the mechanism underlying this protection is poorly understood and consequently limits its possible therapeutic application in AD. Moreover, conventional lithium formulations have a narrow therapeutic window and are associated with a severe side effect profile. Here we evaluated a novel microdose formulation of lithium, coded NP03, in a well-characterized rat model of progressive AD-like amyloid pathology...

Lithium has been marketed in the United States of America since the 1970s as a treatment for bipolar disorder. More recently, studies have shown that lithium can improve cognitive decline associated with Alzheimer's disease (AD). However, the current United States Food and Drug Administration-approved lithium pharmaceutics (carbonate and citrate chemical forms) have a narrow therapeutic window and unstable pharmacokinetics that, without careful monitoring, can cause serious adverse effects. Here, we investigated the safety profile, pharmacokinetics, and therapeutic efficacy of LISPRO (ionic co-crystal of lithium salicylate and l-proline), lithium salicylate, and lithium carbonate (Li2CO3)...

METHODS: Published studies were examined. RESULTS: The importance of amyloid in the pathogenesis of AD is well established, yet accepting it as the main cause for AD is problematic, because amyloid-centric treatments have provided no clinical benefit and about one-third of cognitively normal, older persons have cerebral amyloid plaques...

Lithium intoxication is known to induce cognitive deficits along with motor and behavioral changes, even in association with normal serum levels. However, cases with comprehensive neuropsychological assessment of the deficits are rare. In our patient, we initially found severe cognitive deficits, including apraxia and visuo-constructive problems, and temporo-parietal FDG-PET hypometabolism. Neuropsychological and imaging findings were highly suggestive of Alzheimer's disease. However, lithium intoxication was suspected to account for these findings because of a Parkinson's syndrome, despite serum levels being in the upper therapeutic range...

The pathogenesis of Alzheimer's disease involves multiple pathways that, at the macrolevel, include decreased proliferation plus increased loss affecting neurons, astrocytes, and capillaries and, at the subcellular level, involve several elements: amyloid/amyloid precursor protein, presenilins, the unfolded protein response, the ubiquitin/proteasome system, the Wnt/catenin system, the Notch signaling system, mitochondria, mitophagy, calcium, and tau. Data presented show the intimate, anatomical interactions between neurons, astrocytes, and capillaries; the interactions between the several subcellular factors affecting those cells; and the treatments that are currently available and that might correct dysfunctions in the subcellular factors...

Alzheimer's disease (AD) is the most common cause of dementia in the elderly. The main hallmarks of this disease include progressive cognitive dysfunction and an accumulation of soluble oligomers of β-amyloid (Aβ) 1-42 peptide. In this research, we show the effects of lithium and memantine on spatial memory and neuroinflammation in an Aβ1-42 oligomers-induced animal model of dementia in rats. Aβ 1-42 oligomers were administered intrahippocampally to male wistar rats to induce dementia. Oral treatments with memantine (5mg/kg), lithium (5mg/kg), or both drugs in combination were performed over a period of 17days...
