Lack of published clinical trials and experience in most institutions has resulted in significant challenges for clinicians who manage children with stroke. We report a case of 16-year-old male child who was presented with history of sudden onset of weakness 2 months back and before he could consult the physician, the weakness improved significantly and a misdiagnosis of functional disorder was made at a peripheral hospital. Children with stroke may have subtle manifestations and to make an early diagnosis of stroke in children there is need of awareness about this entity in children. © 2007 Elsevier B.V.

It is under diagnosed because physicians do not usually include it in differential diagnoses [2], and lack of published clinical trials and experience in most institutions has resulted in significant challenges for clinicians who manage children with stroke [3]. We report a case of male child whose initial presentation was mistaken as functional disorder and review the relevant literature. 2. Case report Sixteen-year-old male child presented with history of sudden onset of weakness and mild slurring of speech 2 months back that significantly improved over next few hours. When parents consulted the physician child had only mild residual weakness of right hand. The child was investigated with a CT scan and it was apparently normal (Fig. 1). This episode was dismissed as functional disorder and child was started on anti-anxiety medication. However child was con∗ Corresponding author. Tel.: + 91 7152 3956552; fax: +91 7152 2245318.

The child attended our outpatient clinic and on examination there was mild grip weakness of right hand with mild slurring of speech. The child underwent contrast-enhanced magnetic resonance imaging (MRI) and it showed a chronic infarct in the territory of left middle cerebral artery (Figs. 2 and 3). Monitoring for heart rhythm including ECG and blood pressure were normal. Blood investigations including complete blood count, coagulation profile and erythrocyte sedimentation rate were within normal limits. Colour Doppler of the neck vessels, transoesphageal echocardiography and CT angiography of brain were normal. Lumbar puncture showed two cells all lymphocytes, sugar-45 mg%, protein-30 mg% and culture was sterile. Skin biopsy was not performed. Child was started on low dose aspirin and doing well at follow up. 3. Discussion Stroke in children may present as decline in cognitive performance causing delay in the diagnosis [4]. The initial diagnosis of stroke can be reached after inexpensive tests: history, examination, and head CT [5,6]. Computed A.

In acute stage CT scan may be normal. tomography (CT) is still considered to be the initial imaging study of choice as it is rapid, widely available, and clearly distinguishes hemorrhagic and ischemic stroke [7]. However CT scan may be normal in acute stroke as in present case and can delay the diagnosis [8,9]. MRI with MR angiography and MR venography is more effective for detection of acute ischaemia, and can detect acute and chronic haemorrhage as well and is the preferred investigation in patients with suspected stroke [10,11]. Regarding the radiological findings there is predominant involvement of the left MCA among children (as in the present case) with ischemic stroke leading to right hemiparesis (or hemiplegia) [2,8,12–14]. The workup for the final diagnosis is long and expensive and investigations of children with stroke should be selective and should be guided by clinical suspicion [5,6,9]. Based on clinical features there should be a vigorous search for possible risk factors in pediatric stroke patients (Table 1) [4,8,9,12,15–17]. Cardiovascular and cerebrovascular investigations include electro-cardiogram, echocardiogram, carotid and transcranial Doppler ultrasound [4,8,9,12,15–17]. Assays for factor-V Leiden, prothrombin G20210A, and methylenetetrahydrofolate reductase C677T gene mutations, levels of anticardiolipin antibodies immunoglobulin G and M, homocysteine, protein C, protein S, antithrombin III, antinuclear antibodies, rheumatoid factor, serum complement, and lipoprotein A can be performed where necessary [4,8,9,12,15–17]. A metabolic screening includes: blood glucose, lactate and electrolytes levels, a lipid profile, and renal and liver function tests. Tests for HIV infection (ELISA), syphilis (VDRL), sickle cell anemia (hemoglobin electrophoresis), and iron deficiency may be performed based on clinical suspicion [4,8,9,12,15–17]. Trauma Drugs Metabolic and nutritional disorders Moyamoya disease Because of the high prevalence and importance of multiple risk factors, a complete investigation, including hematologic and metabolic studies and angiography, should be considered in children with ischemic stroke [9,12]. Diagnosing ischaemic stroke and determining its cause, both are important for selection of treatment and prediction of outcome [8,18]. Data from animal and adult stroke studies have demonstrated a benefit for the aggressive treatment of underlying cause [19]. An international study is currently in progress to formally study the incidence, risk factors, treatment strategies and outcomes of stroke in children [1]. Current therapies for arterial ischemic stroke include thrombolytic, antithrombotic and antiplatelet agents, blood transfusion and surgery [1,19]. Blood transfusion in acute ischemic stroke is done for an underlying hypovolemic shock. Prophylactic transfusion prevents strokes in children with sickle cell anemia who have abnormalities on transcranial Doppler ultrasonographic examination [20]. Thrombolysis, though not indicated for patients <18 years of age, is currently being administered to children, with unclear benefit. Larger studies are needed to evaluate the safety and efficacy of this treatment for children [21]. Stroke in children is associated with high recurrence rate, mortality and those who survived experienced long-term neurological or cognitive sequelae [8,9,22,23]. Because of the low incidence, the paucity of information about the best approach to the diagnosis and management of stroke in children and lack of general awareness of cerebrovascular disorders in children all are probably contributors to delay in their diagnosis [5]. Children with stroke require immediate, special attention and preferably managed at an institution that can offer 878 A.

To conclude early management of ischemic stroke certainly deserves more attention from physicians and from the general public, regardless of patient’s age. Recognition of stroke is indeed the very first step in this process.
