A comprehensive approach to Alzheimer's Disease: Exploring Nanotechnology, treatment Innovations, and sex differences

In the world, over 50 million people are living with Alzheimer's disease (AD), and in thirty years, this number is expected to double or even exceed that. AD is a form of dementia characterized by memory loss, language difficulties, and impaired thinking skills. It involves the accumulation of beta-amyloid plaques and tau tangles in the brain, leading to neurodegeneration and disrupted neuron communication. After diagnosis, patients typically survive for four to eight years, though some may live up to 20 years. Currently, there is no cure, and the available treatment options are limited in improving the quality of patients' lives. However, a promising perspective for treatment based on nanotechnology narrows down the possibility of personalized treatment. In this review, we explore several topics related to Alzheimer's disease to provide a comprehensive understanding of how nanotechnology can enhance treatment approaches. We examine various types of nano treatments and delivery methods, as well as the challenges they face and their associated benefits. Additionally, we highlight current nano treatments in development and discuss improved cell and animal models that can effectively test these treatments for patient safety. We also address sex differences in the pathophysiology of Alzheimer's disease, which may allow for more targeted treatment strategies. By considering these factors in conjunction, we move closer to realizing personalized medicine, ultimately improving the quality of life for patients. Nano treatments offer the potential for more specific, safer, and effective solutions in managing Alzheimer's disease.
