Alzheimer’s disease (AD) is an intriguing and still unsolved puzzle that has attracted, over the last decades, the interest of the scientific community. Despite the limited knowledge regarding the initial cause(s) of AD, mitochondrial abnormalities have been pinpointed as one of the earliest and strongest events related with the pathological course of this complex neurodegenerative disease. In this sense, the present chapter addresses three distinct but connected pieces of the AD puzzle: (a) how could defects of mitochondrial bioenergetics and dynamics contribute to AD pathology? (b) Could mitochondrial defects promote the disease-defining amyloid-β‎ and tau pathologies, and vice versa? and (c) Are mitochondria feasible therapeutic targets to postpone AD symptomatology and neuropathology, and, if so, how and when? The understanding and connection of these puzzle pieces provide a more comprehensive picture about the fundamental role of mitochondrial (mal)function in the neurodegenerative processes that occur in AD and propels future research interventions aimed to forestall AD-related pathological phenotype by bolstering mitochondrial “health.”

Abstract Hypouricaemia has received relatively little attention in the literature. As a result, there is less awareness or understanding of the potential risks of low uric acid levels. Emerging research indicates that normal uric acid levels may have an antioxidative and neuroprotective effect. This study aims to investigate possible associations between hypouricaemia and neurodegenerative disease. Data was collected from seventy-seven outpatients and inpatients who underwent routine uric acid testing, who were then stratified into patients with and without neurodegenerative disease. Patients with renal pathologies and patients using uric acid altering medications were excluded from the study. There was a significant difference in the prevalence of Alzheimer’s disease between hypouricemic and normouricemic patients (p = 0.001), however there was no difference in the prevalence of vascular dementia (p = 0.45). This study provides evidence that hypouricaemia has potential effects on health, specifically on the rate of neurodegenerative diseases such as Alzheimer’s disease and gives weight to the potential neuroprotective role of uric acid.

The discovery of charged molecules being able to cross the mitochondrial membrane has prompted many scholars to exploit this idea to find a way of preventing or slowing down aging. In this paper, we will focus on mitochondria-targeted antioxidants, which are cationic derivatives of plastoquinone, and in particular on the mitochondria-targeted antioxidant therapy of neurodegenerative diseases. It is well known that the accumulation of amyloid-β peptide (Aβ) in mitochondria and its related mitochondrial dysfunction are critical signatures of Alzheimer’s disease (AD). In another neurodegenerative disease, Parkinson’s disease (PD), the loss of dopaminergic neurons in the substantia nigra and the production of Lewy bodies are among their pathological features. Pathogenesis of Parkinson’s disease and Alzheimer’s disease has been frequently linked to mitochondrial dysfunction and oxidative stress. Recent studies show that MitoQ, a mitochondria-targeted antioxidant, may possess therapeutic potential for Aβ-related and oxidative stress-associated neurodegenerative diseases, especially AD. Although MitoQ has been developed to the stage of clinical trials in PD, its true clinical effect still need further verification. This review aims to discuss the role of mitochondrial pathology in neurodegenerative diseases, as well as the recent development of mitochondrial targeted antioxidants as a potential treatment for these diseases by removing excess oxygen free radicals and inhibiting lipid peroxidation in order to improve mitochondrial function.

Alzheimer’s disease (AD) is a neurodegenerative disease with complex pathological characteristics, whose etiology and pathogenesis are still unclear. Over the past few decades, the role of the extracellular matrix (ECM) has gained importance in neurodegenerative disease. In this review, we describe the role of the ECM in AD, focusing on the aspects of synaptic transmission, amyloid-β-plaque generation and degradation, Tau-protein production, oxidative-stress response, and inflammatory response. The function of ECM in the pathological process of AD will inform future research on the etiology and pathogenesis of AD.

The revelation of adult brain exhibiting neurogenesis has established that the brain possesses great plasticity and that neurons could be spawned in the neurogenic zones where hippocampal adult neurogenesis attributes to learning and memory processes. With strong implications in brain functional homeostasis, aging and cognition, various aspects of adult neurogenesis reveal exuberant mechanistic associations thereby further aiding in facilitating the therapeutic approaches regarding the development of neurodegenerative processes in Alzheimer’s Disease (AD). Impaired neurogenesis has been significantly evident in AD with compromised hippocampal function and cognitive deficits. Melatonin the pineal indolamine augments neurogenesis and has been linked to AD development as its levels are compromised with disease progression. Here, in this review, we discuss and appraise the mechanisms via which melatonin regulates neurogenesis in pathophysiological conditions which would unravel the molecular basis in such conditions and its role in endogenous brain repair. Also, its components as key regulators of neural stem and progenitor cell proliferation and differentiation in the embryonic and adult brain would aid in accentuating the therapeutic implications of this indoleamine in line of prevention and treatment of AD.
