A state of sudden confusion and altered awareness that may develop rapidly and fluctuate throughout the day.
Medical records documenting a formal diagnosis of delirium are the starting point. For a 10% rating, records showing symptoms appear mainly under stress or that continuous medication is needed to keep them controlled would be relevant. For 30%, records or statements showing occasional drops in work performance alongside symptoms such as depressed mood, anxiety, panic attacks occurring weekly or less often, chronic sleep impairment, or mild memory loss help support that level.
For 50%, evidence of reduced reliability or productivity at work, such as panic attacks more than once a week, impaired short- and long-term memory, impaired judgment, or difficulty understanding complex commands, would be relevant. For 70%, records reflecting deficiencies across most life areas, such as suicidal ideation, impaired impulse control, spatial disorientation, or neglect of personal hygiene, are pertinent. For 100%, documentation of gross impairment in thought or communication, persistent delusions or hallucinations, disorientation to time or place, or memory loss for names of close relatives, own occupation, or own name would support that level. Your own statements and statements from people who know you about how symptoms affect your work and daily life can reflect these criteria as well.
