Brain disorder due to Alzheimer's disease

Major or mild neurocognitive disorder due to Alzheimer's disease is rated under the General Rating Formula for Mental Disorders in § 4.130. Six ratings are possible: 0%, 10%, 30%, 50%, 70%, and 100%.

At 0%, a diagnosis exists but symptoms do not interfere with your work or social life and do not require continuous medication. At 10%, symptoms are mild or transient and reduce your work efficiency only during periods of significant stress, or are controlled by continuous medication. At 30%, you have occasional decreases in work efficiency and intermittent inability to perform work tasks, though you generally function satisfactorily; symptoms may include depressed mood, anxiety, panic attacks weekly or less, chronic sleep problems, or mild memory loss. At 50%, your reliability and productivity are reduced, with symptoms such as memory impairment, impaired judgment, panic attacks more than once a week, or difficulty understanding complex commands. At 70%, you have deficiencies in most areas of life — work, family, judgment, or mood — with symptoms such as suicidal ideation, spatial disorientation, or inability to maintain effective relationships. At 100%, there is total occupational and social impairment, with symptoms such as persistent delusions, memory loss for close relatives' names or your own name, or intermittent inability to perform basic daily activities.
