Background: Alzheimer's Disease (AD) is associated with impairments in key brain Mitogen- Activated Protein Kinase (MAPK) signaling cascades including the p38, c-Jun N-terminal kinase (JNK), ERK and Akt pathways. Apolipoprotein E4 (ApoE4) is the most prevalent genetic risk factor of AD. Objectives: To investigate the extent to which the MAPK signaling pathway plays a role in mediating the pathological effects of apoE4 an Read More

Background: Classified as saccadic intrusions, Square-Wave Jerks (SWJs) have been observed during Visual Fixation (VF) in Alzheimer’s Disease (AD). However, the pathological significance of this phenomenon remains unclear. Objective: The present study analyzed the characteristics of SWJs in patients with AD with their eyes open in the dark without VF. Methods: Fifteen patients with AD and 15 healthy age- and sex-matched co Read More

Background: Apolipoprotein E (APOE) is a prominent genetic risk factor for Alzheimer’s disease (AD) and a frequent target for associations with non-demented and cognitively impaired aging. APOE offers a unique opportunity to evaluate two dichotomous comparisons and selected gradations of APOE risk. Some evidence suggests that APOE effects may differ by sex and emerge especially in interaction with other A Read More

Background: Decreased levels of the neuroprotective growth factors, low-grade inflammation, and reduced neurocognitive functions during aging are associated with neurodegenerative diseases, such as Alzheimer’s disease. Physical exercise modifies these disadvantageous phenomena while a sedentary lifestyle promotes them. Purpose: The purposes of the present study included investigating whether both aerobic and resist Read More

Background: Based on the prevalence studies, the number of people suffering from dementia will almost double every 20 years, to 65.7 million in 2030 and 115.4 million in 2050, assuming no changes in mortality, effective preventative measures, definitive diagnostic guidelines or curative treatment. From the abovementioned epidemiological data, it is obvious that dementia constitutes a major public health problem not onl Read More

Background: Cancer is a common disease caused by the excessive proliferation of cells, and neurodegenerative diseases are the disorders caused due to the degeneration of neurons. Both can be considered as diseases caused by the dysregulation of cell cycle events. A recent data suggests that there is a strong inverse association between cancer and neurodegenerative disorders. There is indirect evidence to postulate Brai Read More

Background: Alzheimer’s Dementia (AD) has a complex pathophysiology that is incompletely understood. Chronic, low-level environmental lead (Pb) exposure is associated with cognitive impairment, hypertension and mortality, and has been proposed as a potential cause of AD. Objective: We aimed to review the literature to clarify the potential role of Pb in AD and to guide future research. Methods: Through a series of system Read More

Introduction: Observational studies have found that physical activity is associated with a reduced risk of cognitive decline and dementia. Whether physical activity may also reduce the level of AD pathology, remains undetermined. Objective: To examine the relationship between physical activity and AD biomarkers (beta-amyloid1- 42, total tau and phosphorylated tau in CSF, amyloid PET, hippocampal atrophy on MRI and parietot Read More
