Neurodegenerative diseases are a group of disorders that cause the progressive loss of structure or function of neurons, which are the cells that make up the brain and nervous system. Treatment of neurodegenerative diseases typically involves a combination of medications, lifestyle changes, and therapies to slow the progression of the disease and manage symptoms. Medications may include cholinesterase inhibitors, which can help improve memory and thinking, and dopamine agonists, which can help improve movement. Lifestyle changes may include exercise, a healthy diet, and stress management. Therapies such as physical, occupational, and speech therapy can help improve motor skills, communication, and daily functioning.
