The hypothesis that early degeneration of the pedunculopontine nucleus (PPN) may be related to nigral degeneration has opened new avenues of basic research for this disease. It is not known how the motor function and nigrostriatal gene expression of TH, VMAT2 and DAT behave in an intermediate term (30 days) following the pontine lesion....

Down syndrome (DS) is the most frequent genetic disease characterized by several neuropathological features including alteration in neurogenesis, mental disability, cognitive impairments, learning-memory deficits and early onset of Alzheimer’s disease (AD). Over expression of chromosome 21 genes, localized in Down Syndrome Critical Region (DSCR), is the main cause of DS neuropathological features. We studied herein one of DSCR genes, DYRK1A (Dual-Specificity Tyrosine-Phosphorylation-Regulated ...

Cognitive changes in Parkinson’s disease (PD) can occur at any stage of the disease and have been shown to significantly impact well-being and life participation. The nature and pattern of cognitive decline in PD remains unclear due to the heterogeneity of symptoms and lack of a clear explanatory model. This review aims to draw attention to several theoretical models of cognitive decline in PD to deepen our understanding of the complex milieu of symptoms and begin to offer clinical implication...

A close and contemplative look at the published neurology literature makes it clear to the reader that epilepsy research possesses more popularity and occupies a higher position in the plethora of scholarly medical writings. Perhaps the reason behind this is that epilepsy nowadays has become more than just transient seizures that are treated with drugs to put an end to seizure recurrence, but rather it is a disease that permeates all aspects of the patient's life. Epilepsy affects not only the p...

The apolipoprotein E4 (APOE4) allele represents the single greatest risk factor for late-onset Alzheimer’s disease (AD) and accumulating evidence suggests that fragmentation with a toxic-gain of function may be a key molecular step associated with this risk. Recently, we demonstrated strong immunoreactivity of a 151 amino-terminal fragment of apoE4 (E4-fragment) within the nucleus of microglia in the human AD brain. In vitro, this fragment led to toxicity and activation of inflammatory process...

Parkinson’s disease (PD) is the second most common neurodegenerative disease, presenting with the loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc) and motor symptoms. Categorized as a synucleinopathy, the pathological hallmark of PD is intracellular filamentous Lewy bodies (LB), which are formed from protopathic aggregates. The most prevalent of these proteins is the presynaptic protein ɑ-synuclein (α-syn). While commonly attributed to neuronal death in SNpc, postmor...

Alzheimer’s disease (AD), the most common type of dementia or neurodegenerative diseases since the beginning of the past century when it was coined by the German psychiatrist, Alois Alzheimer in 1901 holds an allusive etiology, and as a result failed most treatment and prevention strategies. Despite the common belief among the experts of AD being a genetic disease, the genetic heritability of this disease has such a wide range of 50-80% in twin and family studies that questions the totality of...

The phenomenon of “Westernization” in Asian countries which includes a specific choice of food and lifestyle was related to the higher prevalence of MS in Asia’s population which almost supports new findings on the great influence of gut and its microbiota in people worldwide. The current conventional therapy helps to prolong the periods between attacks and relapses, but in fact, does not slow down the disease progression and impact on physical activities which eventually leads to disabili...

The motor and non-motor deficits of Parkinson’s disease (PD) can cause daily challenges and have been associated with reduced health-related quality of life (HrQoL). A number of variables have been consistently, though not unequivocally, identified as important in influencing overall HrQoL in individuals with PD, such as demographic factors, cognitive decline, and level of motor impairment. However, the presence and severity of dysarthria is often overlooked, despite the potentially adverse in...

The mammalian brain depends on a continuous supply of oxygen and glucose to meet metabolic demand. Adaptive mechanisms allow brain cells to exist under conditions of moderately low oxygen when ‘idling’ or exposure to high altitude as well as elevated oxygen delivery when activated. Regulation involves numerous intrinsic and extrinsic adaptive mechanisms that serve to maintain metabolic homeostasis. Under conditions of chronic low oxygen (10%) endogenous changes in CNS angiodynamics help prom...

Alzheimer is one of the most common causes of dementia that influence nerve cells in various parts of the brain. Pathologically it is caused because of intracellular neurofibrillary tangles and extracellular amyloidal protein and results in the deposition of plaques which obstruct the communication between the nerve cells resulting in this neurodegenerative disease. The genetic risk factor found to be associated with this disease is mutation in APP, PSEN1 and PSEN2 genes. Also, the diet and nutr...

Physical activity has the potential to improve cognition for those with dementia, as demonstrated by randomised controlled trials lasting at least 6 weeks. Research is yet to explore the acute cognitive effects of physical activity for people with dementia. Acute resistance physical activity with healthy late-middle aged individuals has been shown to facilitate general cognition, as well as benefit executive function specifically. This study therefore aimed to establish if people with dementia e...

We report logistic regression analyses findings from a community sample of elderly Mexican Americans and non-Hispanic whites demonstrating that degrees of associations between diabetes and PD with CImp persist after controlling for effects of functional decline. However, after adding effects of a number of control variables (including ethnicity) to the equation, association between diabetes and CImp is no longer significant. We suggest that these findings may well be an artifact of the high prev...

Alzheimer's disease is an age-related and irreversible disease and characterized progressively decline in cognitive functions such as memory, speech, executive functions and visual-spatial skills. Currently, there is no a simple and definitive diagnosis method for clinical management. It is possible to diagnose with 85-90% accuracy with clinical assesment and neuropsychological tests. The precisely-known risk factors associated with Alzheimer's disease are aging, family history, and the presence...

Although harboring the Apolipoprotein E4 (APOE4) allele is a well-known risk factor in Alzheimer's disease (AD), whether a similar risk holds true for Parkinson's disease (PD) is currently not known. To investigate whether apoE pathology is present in PD, an immunohistochemical study was undertaken with fixed, human PD brain sections from the substantia nigra utilizing a recently characterized antibody that detects an amino-terminal fragment of apoE. This antibody, termed the apoE cleavage fragm...
