Why is ADD a permanent disqualifier?

Attention Deficit Disorder (ADD) can be considered a permanent disqualifier in certain contexts, such as specific jobs or military service, because it may significantly impact an individual's ability to perform tasks that require sustained attention, focus, and organization. These roles often require high levels of concentration and reliability, and the symptoms of ADD can hinder performance, safety, and effectiveness. However, it's important to note that the impact of ADD varies widely among individuals, and many successfully manage their symptoms with appropriate strategies and support.
