New Approaches to the Treatment of Alzheimer’s Disease

Alzheimer’s disease (AD) is one of the most common chronic neurodegenerative disorders worldwide. It is characterized by progressive memory loss and cognitive decline, leading to dementia. The pathogenesis of the disease is primarily attributed to two pathological protein structures: amyloid-beta (Aβ) plaques and tau protein neurofibrils. The current treatment strategies for AD are mainly symptomatic, highlighting the urgent need for the development of new, more effective therapies for the disease. The purpose of this paper is to provide a comprehensive and scientific review of the latest research regarding novel therapeutic options in the treatment of AD. In recent years, research has focused on more advanced and diversified strategies, including immunotherapy, gene therapy, tyrosine kinase inhibitors, therapies targeting mitochondrial function, and neurogenesis-related process modulation. One of the most promising treatment strategies for AD is immunotherapy. Intensive research is currently underway on both passive immunization, which involves the administration of monoclonal antibodies, and active immunization through vaccinations that stimulate the body to produce specific antibodies. Further research into novel therapeutic directions is essential, particularly concerning the role of the immune system in the pathogenesis of AD. Immunization appears to be a highly promising approach to developing effective methods for preventing AD or delaying the progression of this disease.
