Introduction
Neurodegenerative disorders represent a group of debilitating conditions characterized by the progressive degeneration of the structure and function of the nervous system. Conditions such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and amyotrophic lateral sclerosis (ALS) pose significant challenges to individuals affected and their families. Over the years, extensive research has been conducted to understand the underlying mechanisms of neurodegeneration and to develop novel treatment approaches that can potentially slow down or halt the progression of these disorders. This article explores the latest advancements in the field of new treatment approaches for neurodegenerative disorders, focusing on emerging therapies and promising strategies.
