The general mental-disorders formula describes occupational and social impairment. Its symptom examples are considered with frequency, severity, duration and the broader record under §4.126.
How the criteria work
100% · General mental disorders formula, 100 percent
The source begins with total occupational and social impairment. The listed symptoms sit within that impairment description; this is not a symptom-count calculation.
Total occupational and social impairment, due to such symptoms as: gross impairment in thought processes or communication; persistent delusions or hallucinations; grossly inappropriate behavior; persistent danger of hurting self or others; intermittent inability to perform activities of daily living (including maintenance of minimal personal hygiene); disorientation to time or place; memory loss for names of close relatives, own occupation, or own name.
70% · General mental disorders formula, 70 percent
The source describes occupational and social impairment with deficiencies in most areas. The whole record and longitudinal context under §4.126 remain relevant.
Occupational and social impairment, with deficiencies in most areas, such as work, school, family relations, judgment, thinking, or mood, due to such symptoms as: suicidal ideation; obsessional rituals which interfere with routine activities; speech intermittently illogical, obscure, or irrelevant; near-continuous panic or depression affecting the ability to function independently, appropriately and effectively; impaired impulse control (such as unprovoked irritability with periods of violence); spatial disorientation; neglect of personal appearance and hygiene; difficulty in adapting to stressful circumstances (including work or a worklike setting); inability to establish and maintain effective relationships.
50% · General mental disorders formula, 50 percent
The source describes reduced reliability and productivity, with examples of symptoms. A checked symptom is not by itself a percentage determination.
Occupational and social impairment with reduced reliability and productivity due to such symptoms as: flattened affect; circumstantial, circumlocutory, or stereotyped speech; panic attacks more than once a week; difficulty in understanding complex commands; impairment of short- and long-term memory (e.g., retention of only highly learned material, forgetting to complete tasks); impaired judgment; impaired abstract thinking; disturbances of motivation and mood; difficulty in establishing and maintaining effective work and social relationships.

The row includes occasional work-efficiency decrease and intermittent inability to perform tasks, alongside generally satisfactory functioning. Preserve those qualifications.
Occupational and social impairment with occasional decrease in work efficiency and intermittent periods of inability to perform occupational tasks (although generally functioning satisfactorily, with routine behavior, self-care, and conversation normal), due to such symptoms as: depressed mood, anxiety, suspiciousness, panic attacks (weekly or less often), chronic sleep impairment, mild memory loss (such as forgetting names, directions, recent events).

This row contains an OR: mild/transient symptoms with stress-related effects, or symptoms controlled by continuous medication. Do not replace the row with a symptom tally.
Occupational and social impairment due to mild or transient symptoms which decrease work efficiency and ability to perform occupational tasks only during periods of significant stress, or symptoms controlled by continuous medication.

A formal diagnosis is described, with symptoms not severe enough for the stated functional interference or continuous-medication requirement. Diagnosis and evaluation are different questions.
A mental condition has been formally diagnosed, but symptoms are not severe enough either to interfere with occupational and social functioning or to require continuous medication.
