The Akt/CREB signalling pathway is involved in neuronal survival and protection. Autophagy is also likely to be involved in survival mechanisms. Nimodipine is an L-type calcium channel antagonist that reduces excessive calcium influx during pathological conditions (contributing to its neuroprotective properties). However, the potential role of nimodipine in autophagic and Akt/CREB signalling is not well understood. In addition, little is known about the relationship between autophagic and Akt/CREB signalling...

Alzheimer's disease (AD) is the most common cause of dementia in elderly people. Because of the lack of effective treatments for this illness, research focused on identifying compounds that restore cognition and functional impairments in patients with AD is a very active field. Since its discovery in 1993, the serotonin 5-HT6 receptor has received increasing attention, and a growing number of studies supported 5-HT6 receptor antagonism as a target for improving cognitive dysfunction in AD. This article reviews the rationale behind investigations into the targeting of 5-HT6 receptors as a symptomatic treatment for cognitive and/or behavioral symptoms of AD...

BACKGROUND: To this day the definite diagnosis of Alzheimer's disease still relies on post-mortem histopathological detection of neurofibrillary tangles and beta-amyloid deposits. Amyloid positron emission tomography (PET) is a new diagnostic tool that enables the in vivo quantification of pathological beta-amyloid deposits. The aim of the current study was to evaluate to what extent (18)F-florbetaben-PET (FBB-PET) influences the diagnosis of patients with dementia. MATERIAL AND METHODS: Imaging with FBB-PET was performed on 33 patients from our outpatient department for cognitive neurology...

Apomorphine infusion or injection is an important dopamine agonist non-oral therapy usually used in advanced Parkinson's disease (PD) with refractory motor fluctuations. The drug also has appreciable efficacy for nonmotor fluctuations and is the quickest to reverse predictable "off" periods. Current subcutaneous administration, however, is complicated by problems associated with needle-based therapies, such as skin nodule formation, skin irritation, and avoidance of this treatment option by needle-phobic subjects...

This review presents the results of studies investigating the effects of transcranial magnetic stimulation (TKMS) on motor and non-motor symptoms of Parkinson's disease (PD). It has been found that TKMS reduces the severity of both motor and non-motor disorders without causing serious side-effects. Magnetic field therapy can be combined with pharmacological and non-drug therapies, including the use of dopaminergic therapy, antidepressants and anti-dementia drugs, as well as stereotactic operations. It is necessary to continue the study of the influence of TKMS on the severity of PD symptoms using different electromagnetic characteristics...

Behavior analytic approaches and techniques have much to offer to the study of remembering. There is currently great interest in the development of animal models of human memory processes in order to enhance understanding of the neurobiology of memory and treatment of dementia and related disorders. Because rodent models are so important in contemporary neuroscience and genetics, development of procedures to study various forms of memory in rodents is a point of emphasis. The sense of smell plays an important role in rodent behavior and use of olfactory stimuli has permitted demonstrations of complex forms of stimulus control that have also served as baselines for studying drug effects on remembering...

Alzheimer's disease (AD) is the most common cause of dementia in the elderly. Pharmacological treatment of AD includes Anticholinesterase Inhibitors (AChEIs) for mild-moderate AD, and memantine for severe AD. These drugs provide mainly symptomatic short-term benefits without clearly influencing the progression of the disease. Pioglitazone (AD4833) is an insulin sensitizer of the thiazolidinedione class of nuclear Peroxisome-Proliferator Activated Receptor γ (PPARγ) agonists. It binds to PPARγ, affecting gene transcription and reducing inflammation...

Prolonged ischemia can result in apoptotic death of vascular endothelial cells and lead to ischemic vascular diseases including vascular dementia, arteriosclerosis and brain oedema. Finding protective strategies to prevent this is therefore an urgent mission. Recent studies have shown that dysregulation of microRNAs (miRNAs) can lead to imbalance of Bcl-2 family proteins and mitochondrial dysfunction, leading to further damage of vascular cells under ischemic conditions. However, whether miRNAs can be used as a drug target for treating vascular diseases is not fully understood...

The key lipid-lowering target is to achieve guideline-recommended low-density lipoprotein cholesterol (LDL-C) levels, usually by using statins. The new treatment strategies for lipid-lowering therapy include using proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors as an exciting approach to reduce residual risk of cardiovascular diseases (CVD). However, concerns about possible adverse effects, including neurocognitive disorders, were issued by the Food and Drug Administration (FDA). The current disputable evidence does not allow definite conclusions as to whether statins contribute to, or cause, clinically meaningful cognitive impairment...
