Madness
Cognitive Collapse
The frequent terminus of contact with the mythos - not always dysfunction, but sometimes expanded perception mortals cannot sustain, and sometimes the only sane response to an insane cosmos.
It is not because of anything that can be seen or heard or handled, but because of something that is imagined.
Clinical note, Arkham Sanitarium, 1929
Overview
Madness in the archive is not a single diagnosis. It is a spectrum: organic psychosis unrelated to the mythos; trauma response to witnessed horror; and revelation shock - the accurate understanding of what was seen, which the mind cannot integrate without breaking or adapting in ways that look like breaking to outside observers.
Danforth saw something beyond the Antarctic city and never fully returned. Thurston died before he could see more. Olmstead may have been protected by partial belief. The archive distinguishes collapse from expansion: some madmen see too much; some see correctly.
Description
Symptoms cluster predictably: hyperacusis to certain syllables; refusal to sleep or inability to wake; drawing of non-Euclidean angles; genealogical obsession; aquatic phobia or aquatic compulsion; laughter at inappropriate moments; and the phrase 'Tekeli-li' or 'Ph'nglui' spoken without conscious intent.
Treatment in ordinary sanitariums fails because the patient is not always wrong about what they saw. Sedation helps sleep; it does not unsee R'lyeh.
Historical Record
Arkham Sanitarium's census correlates with university research calendars more tightly than the Board admits. Innsmouth internees exhibited hybrid traits misdiagnosed as hysteria. Post-Antarctic personnel were encouraged to retire. The archive maintains a ward list that official medicine does not acknowledge.
Nyarlathotep specializes in madness as art form - delivering knowledge until the recipient becomes his instrument.
Archive Notes
Do not mock the mad in our files; they paid for their testimony. Personnel exhibiting symptoms after field work are to report voluntarily; mandatory review follows third unbidden citation of forbidden text. Madness is not failure of character. It is often the bill for seeing the invoice the universe sends.
