Adult Neuroaxonal Dystrophy (AND) is a rare neurodegenerative disorder characterized by the progressive degeneration of nerve cells in the brain. This condition, also known as NAD, primarily affects individuals in adulthood, leading to a variety of motor and cognitive impairments. Synonyms for AND include adult-onset neuroaxonal dystrophy, adult-onset NAD, and adult-onset neuronal ceroid lipofuscinosis. These terms are used interchangeably to describe the same debilitating condition. Though AND is extremely rare, understanding its synonyms is important for accurate diagnosis, effective treatment, and to improve awareness among healthcare professionals and general public about this devastating neurodegenerative disorder.
