AD is considered a multifactorial disease. Two main hypotheses have been proposed as the cause of AD. The cholinergic hypothesis and the amyloid hypothesis. In addition, several risk factors have been implicated in this disease, including aging, genetic factors, head trauma, vascular disease, infections, and environmental factors. Currently, there are only two classes of drugs approved for the treatment of AD, including cholinesterase enzyme inhibitors and N-Methyl-D-Aspartic Acid (NMDA) antagonists, which are not associated with AD symptoms or disease. Prevent. Today, research is focused on understanding the pathology of AD by targeting multiple mechanisms such as alteration of AD course. This review describes the drugs currently available and future theories for the development of new treatments for AD, including Disease-Modifying Therapies (DMTs), chaperones, and natural products.","PeriodicalId":90442,"journal":{"name":"Austin Alzheimer's and Parkinson's disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82453717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two most common sites for DBS are the Subthalamic Nucleus (STN) and Globus Pallidus (GPi). In this study, the clinical effectiveness of these two targets was compared. Methods: A systematic literature search in electronic databases were restricted to English language publications 2010 to 2021. Specified MeSH terms were searched in all databases. Studies that evaluated the Unified Parkinson’s Disease Rating Scale (UPDRS) III were selected by meeting the following criteria: (1) had at least three months follow-up period; (2) compared both GPi and STN DBS; (3) at least five participants in each group; (4) conducted after 2010. Study quality assessment was performed using the Modified Jadad Scale. Results: 3577 potentially relevant articles were identified 3569 were excluded based on title and abstract, duplicate and unsuitable article removal. Eight articles satisfied the inclusion criteria and were scrutinized (458 PD patients). Majority of studies reported no statistically significant between-group difference for improvements in UPDRS III scores. Conclusions: Although there were some results in terms of action tremor, rigidity, and urinary symptoms, which indicated that STN DBS might be a better choice or regarding the adverse effects, GPi seemed better; but it cannot be concluded that one target is superior. Other larger randomized clinical trials with longer follow-up periods and control groups are needed to decide which target is more efficient for stimulation and imposes fewer adverse effects on the patients.","PeriodicalId":90442,"journal":{"name":"Austin Alzheimer's and Parkinson's disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84311983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently no therapy is available to slow down, reverse or prevent the disease. Here we analyze the existing data in literature and hypothesize that the physiological function of the Amyloid Precursor Protein (APP) is activating the AppBp1 pathway and this function is gradually lost during the progression of AD pathogenesis. The AppBp1 pathway, also known as the neddylation pathway, activates the small ubiquitin-like protein nedd8, which covalently modifies and switches on Cullin ubiquitin ligases, which are essential in the turnover of cell cycle proteins. Here we discuss how APP may activate the AppBp1 pathway, which downregulates cell cycle markers and protects genome integrity. More investigation of this mechanism-driven hypothesis may provide insights into disease treatment and prevention strategies.</p>","PeriodicalId":90442,"journal":{"name":"Austin Alzheimer's and Parkinson's disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4283775/pdf/nihms-634547.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32958515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
