The original and modified* explicit diagnostic criteria for transient ischemic attacks (EDCT) in cerebral infarction with transient symptoms and migraine with aura
| EDCT | Stroke (N = 59) | Migraine with aura (N = 324) |
|---|---|---|
| A Sudden onset of fully reversible neurological or retinal symptoms (typically hemiparesis, hemihypesthesia, aphasia, neglect, amaurosis fugax, hemianopsia, or hemiataxia), n (%) | 50 (85) | 67 (21) |
| B Duration < 24 h, n (%) | 59 (100) | 324(100) |
| C At least two of the following, n (%) | 53 (90) | 74 (23) |
| C1 At least 1 symptom is maximal in < 1 min (no gradual spread), n (%) | 50 (85) | 67 (21) |
| C2 2 or more symptoms occur simultaneously, n (%) | 14 (24) | 30 (9) |
| C3 Symptoms in the form of deficits (no irritative symptoms such as photopsias, pins and needles, etc.), n (%) | 42 (71) | 48 (15) |
| C4 No headache accompanies or follows the neurological symptoms within 1 h, n (%) | 40 (68) | 16 (5) |
| C* At least two of the following, n (%) | 48 (81) | 11 (3) |
| C1* All symptoms are maximal in < 1 min (no gradual spread), n (%) | 42 (71) | 9 (3) |
| C2* All symptoms occur simultaneously, n (%) | 9 (15) | 2 (1) |
| C3* All symptoms are deficits (no irritative symptoms such as photopsias, pins and needles, etc.), n (%) | 39 (66) | 3 (1) |
| C4* No headache accompanies or follows the neurological symptoms within 1 h, n (%) | 40 (68) | 16 (5) |
| D None of the following isolated symptoms (can occur together with more typical symptoms): shaking spells, diplopia, dizziness, vertigo, syncope, decreased level of consciousness, confusion, hyperventilation associated paresthesias, unexplained falls or amnesia, n (%) | 59 (100) | 324 (100) |
| E No evidence of acute infarction in the relevant area on neuroimaging, n (%) | 0 | n/a |
