In particular, many pharmacological studies on sage has been performed on volatile constituents (essential oils). can be considered as an antioxidant, as in the case of dietary phytochemicals [19,20]. 2.2. Alzheimers (AD) and Parkinsons (PD) diseases Amongst a variety of neurodegenerative diseases, Alzheimer’s disease is the most prevalent and devastating disorder and the first cause of institutionalisation in the elderly population. Clinical signs of AD are characterized by progressive and irreversible memory deficits, cognitive deterioration and personality changes, usually with an onset after 65 years of age. Memory impairment appears in the early stage of the disease, and motor and sensory functions are not affected until later stages. Parkinson’s disease is the second most common ageing-related neurodegenerative diseases that can greatly impair quality of life. As opposed to cognitive deficits of AD, PD is a movement disorder, whose classical signs include resting tremors, bradykinesia, extrapyramidal rigidity and loss of postural reflexes such as disturbance in walking or equilibrium. The consequence of these diseases are also very significant in terms of the cost of caring for patients [21,22]. 2.2.1. Epidemiology of AD and PD Incidence rates of neurodegenerative diseases such as AD and PD increase exponentially with age. According to the World Health Corporation (WHO), neurodegenerative diseases will become the worlds second leading cause of death by the middle of the century, overtaking malignancy [23]. In 2000, there were 4.5 million People in america diagnosed with AD, with an annual estimated cost of $100 billion [24]. Presently, it is expected that by 2050 the number of AD patients in the US population could range from 11 to 16 million if no treatment or preventive measure is found [25]. AD is the most common cause of dementia in the elderly and accounts for 60C80% of instances. According to the Global Burden of Disease Study, dementia and additional neurodegenerative disorders will become, by 2020, the eighth cause of disease burden for developed areas [26]. In Europe, AD shows a prevalence of 0.4% in ladies and 0.3% in men aged 60C69 years [27]. PD affects approximately 1% of human population aged 65C69 years and the prevalence raises to 3% in the 80 yr older or above group [28]. Its incidence is definitely approximately 1.5 times higher in men than woman whatsoever ages [29]. It is estimated that in Western Europe, by 2030, the GW-406381 number of PD instances will GW-406381 double from 4.5 to 9 million [30]. The prevalence of PD varies in different ethnic and geographic organizations [31]. For instance, a north-south geographic gradient has been observed for PD, with prevalence increasing with latitude in both hemispheres, as compared with the equatorial zones. Furthermore, white populations appear more at risk than black subjects [32]. 2.2.2. Neuropathology of AD and PD Although AD and PD mainly differ in their medical symptoms and disease program, both disorders are essentially provoked by a progressive loss of neurons in different neuronal systems. GW-406381 Furthermore, as for most neurodegenerative diseases, they are characterized by the aggregation of intracellular proteins [33]. The presence of extracellular senile plaques and intracellular build up of neurofibrillary tangles (NFTs) in mind cells of affected individuals have been identified as histopathologic alterations of AD. Senile plaques are composed of fibrillar amyloid (A) peptides produced by cleavage of the A precursor protein (APP), whereas NFTs consist of hyperphosphorylated microtubule connected tau protein (P). Selective neuronal loss is particularly severe in specific cerebral areas: the neocortex, hippocampus, limbic system and subcortical areas [34]. PD is definitely characterized by the selective degeneration of dapaminergic neurons located in the pars compacta of.Just one cup of green tea materials 20C35 mg of EGCG, which has the highest antioxidant activity of all the green tea catechins [216]. disorder and the first cause of institutionalisation in the elderly population. Clinical indications of AD are characterized by progressive and irreversible memory space deficits, cognitive deterioration and personality changes, usually with an onset after 65 years of age. Memory impairment appears in the early stage of the disease, and engine and sensory functions are not affected until later on phases.

PD affects approximately 1% of human population aged 65C69 years and the prevalence increases to 3% in the 80 12 months aged or above group [28]. Its incidence is approximately 1.5 times higher in men than woman at all ages [29]. It is estimated that in Western Europe, by 2030, the number of PD cases will double from 4.5 to 9 million [30]. The prevalence of PD varies in different ethnic and geographic groups [31]. For instance, a north-south geographic gradient has been observed for PD, with prevalence increasing with latitude in both hemispheres, as compared with the equatorial zones. Furthermore, white populations appear more at risk than black subjects [32]. 2.2.2. Neuropathology of AD and PD Although AD and PD largely differ in their clinical symptoms and disease course, both disorders are basically provoked by a progressive loss of neurons in different neuronal systems. Furthermore, as for most neurodegenerative diseases, they are characterized by the aggregation of intracellular proteins [33]. The presence of extracellular senile plaques and intracellular accumulation of neurofibrillary tangles (NFTs) in brain tissues of affected patients have been identified as histopathologic alterations of AD. Senile plaques are composed of fibrillar amyloid (A) peptides produced by cleavage of the A precursor protein (APP), whereas NFTs consist of hyperphosphorylated microtubule associated tau protein (P). Selective neuronal loss is particularly severe in specific cerebral areas: the neocortex, hippocampus, limbic system and subcortical areas [34]. PD is usually characterized by the selective degeneration of dapaminergic neurons located in the pars compacta of the substantia nigra. One of the main neuropathological hallmarks of PD is the aggregation of the intracellular protein -synuclein, to form intracytoplasmic inclusions (Lewy body) in these neurons [35]. 2.2.3. Etiopathogenesis of AD and PD The etiology of neurodegenerative diseases is usually multifactorial, with a complex combination of genetic and non-genetic components. Most neurodegenerative diseases occur sporadically, arising from the conversation among environmental.[PubMed] [CrossRef] [Google Scholar] 87. emphasis will be placed on the antioxidant and anti-inflammatory activity exerted by specific molecules present in food plants or in remedies prescribed by herbal medicines. nonenzymatic scavengers abundant in food and medicinal plants and launched by diets [15,16,17,18]. Any compound capable of quenching ROS, without itself undergoing conversion to a destructive radical species, can be considered as an antioxidant, as in the case of dietary phytochemicals [19,20]. 2.2.

AD is the most common cause of dementia in the elderly and accounts for 60C80% of cases. According to the Global Burden of Disease Study, dementia and other neurodegenerative disorders will be, by 2020, the eighth cause of disease burden for developed regions [26]. In Europe, AD shows a prevalence of 0.4% in women and 0.3% in men aged 60C69 years [27]. PD affects approximately 1% of populace aged 65C69 years and the prevalence increases to 3% in the 80 12 months aged or above group [28]. Its incidence is approximately 1.5 times higher in men than woman whatsoever ages [29]. It’s estimated that in Traditional western European countries, by 2030, the amount of PD instances will dual from 4.5 to 9 million [30]. The prevalence of PD varies in various cultural and geographic organizations [31]. For example, a north-south geographic gradient continues to be noticed for PD, with prevalence raising with latitude in both hemispheres, in comparison using the equatorial areas. Furthermore, white populations show up more in danger than black topics [32]. 2.2.2. Neuropathology of Advertisement and PD Although Advertisement and PD mainly differ within their medical symptoms and disease program, both disorders are essentially provoked with a progressive lack of neurons in various neuronal systems. Furthermore, for most neurodegenerative illnesses, they are seen as a the aggregation of intracellular protein [33]. The current presence of extracellular senile plaques and intracellular build up of neurofibrillary tangles (NFTs) in mind cells of affected individuals have been defined as histopathologic modifications of Advertisement. Senile plaques are comprised of fibrillar amyloid (A) peptides made by cleavage from the A precursor proteins (APP), whereas NFTs contain hyperphosphorylated microtubule connected tau proteins (P). Selective neuronal reduction is particularly serious in particular cerebral areas: the neocortex, hippocampus, limbic program and subcortical areas [34]. PD can be seen as a the selective degeneration of dapaminergic neurons situated in the pars compacta from the substantia nigra. One of many neuropathological hallmarks of PD may be the aggregation from the intracellular proteins -synuclein, to create intracytoplasmic inclusions (Lewy physiques) in these neurons [35]. 2.2.3.

Alzheimers (Advertisement) and Parkinsons (PD) illnesses Amongst a number of neurodegenerative illnesses, Alzheimer’s disease may be the most common and damaging disorder as well as the first reason behind institutionalisation in older people population. Clinical symptoms of Advertisement are seen as a intensifying and irreversible memory space deficits, cognitive deterioration and character changes, generally with an starting point after 65 years. Memory impairment shows up in the first stage of the condition, and engine and sensory features aren’t affected until later on phases. Parkinson’s disease may be the second most common ageing-related neurodegenerative illnesses that can significantly impair standard of living. Instead of cognitive deficits of Advertisement, PD can be a motion disorder, whose traditional signs include relaxing tremors, bradykinesia, extrapyramidal rigidity and lack of postural reflexes such as for example disturbance in strolling or equilibrium. The result of these illnesses are also extremely significant with regards to the expense of caring for individuals [21,22]. 2.2.1. Epidemiology of Advertisement and PD Occurrence prices of neurodegenerative illnesses such as Advertisement and PD boost exponentially with age group. Based on the Globe Health Firm (WHO), neurodegenerative illnesses can be the worlds second leading reason behind death by the center of the hundred years, overtaking tumor [23]. In 2000, there have been 4.5 million People in america diagnosed with Advertisement, with an annual approximated cost of $100 billion [24]. Currently, it is expected that by 2050 the amount of AD patients in america population could range between 11 to 16 million if no get rid of or precautionary measure is available [25]. AD may be the many common reason behind dementia in older people and makes up about 60C80% of instances. Based on the Global Burden of Disease Research, dementia and additional neurodegenerative disorders will become, by 2020, the 8th reason behind disease burden for created areas [26]. In European countries, AD displays a prevalence of 0.4% in ladies and 0.3% in men aged 60C69 years [27]. PD impacts around 1% of inhabitants aged 65C69 years as well as the prevalence raises to 3% in the 80 season outdated or above group [28]. Its occurrence is around 1.5 times higher in men than woman whatsoever ages [29]. It’s estimated that in Traditional western European countries, by 2030, the amount of PD instances GW-406381 will dual from 4.5 to 9 million [30].
