중풍전조증 中風前兆證

Prodrome of wind stroke disorder

Where they diverge

Traditional concepts do not map one-to-one onto modern diagnoses. Read the divergence note first.

The traditional concept is broader. It is a retrospective, prognostic category covering any bodily change preceding a stroke, so both its time window and symptom range exceed that of a transient ischaemic attack; a Korean survey reported that 93.3% of confirmed infarction patients recalled some symptom within the preceding three years. Conversely it does not specify what constitutes a TIA in modern practice. The 2023 American Heart Association statement recommends multimodal MRI within 24 hours of head CT, and reclassifies the event as infarction rather than TIA if diffusion-weighted imaging shows infarct. Aetiological workup and immediate secondary prevention are likewise absent from the traditional category.

Research confidence: medium. The full assessment, in Korean, is in docs/PATTERN_RESEARCH_KCD_DISEASES.md.
The modern correspondences come from literature research, not from an official KCD or KTKP mapping, so the highest mapping confidence is not assigned.
Full evidence and citations are in docs/PATTERN_RESEARCH_KCD_DISEASES.md.
KCD does not carry the Donguibogam volume, so it is left blank here. It needs checking against the original text.
The ICD-11 TM1 code is shown alongside because the two classifications carry the exact same official English name. It is not a mapping we created (§11-R2).

Signs that need immediate medical assessment

Among the symptoms described as premonitory, the following are emergencies even if they resolve on their own within minutes: sudden one-sided weakness or paralysis, one-sided loss of sensation, slurred speech or inability to speak, sudden loss of vision in one eye or part of the visual field, sudden severe headache, and sudden loss of balance or difficulty walking. The 2023 American Heart Association statement (Stroke 2023;54(3):e109-e121) reports a 90-day stroke risk of up to 17.8% after a transient ischaemic attack, with almost half of those strokes occurring within 48 hours, and recommends multimodal MRI within 24 hours of head CT and neurological assessment within 48 hours (one week at the latest). Conversely, the absence of non-specific items such as isolated dizziness, memory decline, neck stiffness or eyelid twitching must never be used to reassure someone who has focal symptoms. This code cannot serve as grounds for self-diagnosis in place of emergency assessment.
