The Oxford Community Stroke Project (OCSP) classification describes the clinical presentation of stroke and is useful in clinical practice and research.
Using this system, stroke patients are first classified as TACS (where ‘S’ denotes Syndrome), PACS, POCS or LACS until cerebral imaging allows the differentiation between infarction and haemorrhage.
Infarcts were subdivided according to clinical presentations when their symptoms were maximal. Stroke subtypes were classified as follows:
| Stroke Subtype | Percentage (%) of infarcts |
|---|---|
| Total Anterior Circulation Infarcts (TACI) | 17% |
| Partial Anterior Circulation Infarcts (PACI) | 34% |
| Posterior Circulation Infarcts (POCI) | 24% |
| Lacunar Infarcts (LACI) | 25% |
