“…It can be hypothesized (Fig ) that absence of α‐thalassaemia, G6PD deficiency, severe anaemia and haemolysis are risk factors for abnormal TCD, which is a risk factor for intracranial stenosis, itself a risk factor for silent infarct. Moreover, extracranial internal carotid tortuosities, which are more frequent in boys are risk factors for extracranial stenoses, themselves associated with the presence of silent infarcts (Verlhac et al , ). Clinical factors, such as ACS, have been shown to be significantly associated with stroke (Ohene‐Frempong et al , ) and elevated systolic blood pressure with stroke (Ohene‐Frempong et al , ) and silent cerebral infarcts (DeBaun et al , ) whereas acute anaemia episodes were significantly associated with acute silent cerebral infarcts (Quinn & Dowling, ).…”
