Nanomedicine-Based Approaches for the Treatment of Dementia explores a wide range of promising approaches for the diagnosis and treatment of dementia. The book begins with introductory sections on dementia and brain ailments that are followed by further chapters that discuss detailed information about challenges of drug delivery across the blood-brain barrier as well as the current status. This book helps readers design and develop novel drug delivery systems and devices for the treatment of dementia that take advantage of recent advances in nanomedical technologies. Numerous drug delivery systems have been developed recently for dementia. Unfortunately, most of them are ineffective since dementia is not a single disease. It is an umbrella term for several neurodegenerative conditions which alter brain functions. Due to this, there is an urgent need for innovative technologies/nano drug delivery systems to improve the targeting and delivery of therapeutic as well as diagnostic agents specifically for treating dementia.
