Neurodegenerative diseases are a group of disorders characterized by the progressive degeneration and death of nerve cells in the brain or peripheral nervous system. This can lead to a range of symptoms, including cognitive decline, movement disorders, and changes in behavior or personality. Common neurodegenerative diseases include Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS). These diseases are typically chronic and currently have no cure, making them a major area of research for developing effective treatments and therapies to slow down or stop the progression of these debilitating conditions.
