Objective: Objective: The aim of this study was to identify MD in a sample of acute stroke patients and to determine their frequency, clinical characteristics, and localization.
Background: Background: 1-4% of strokes are associated with movement disorders (MD). Basal ganglia, thalamus, and cerebellum are usually the involved pathoanatomical sites.
Method: Methods: A prospective observational study conducted along one year within the neurology departments of Ain Shams university and kafr El sheikh university hospitals. After a formal written consent all acute stroke patients were subjected to clinical and neurological history and examination through NIHSS, Fahn-Tolosa-Marin tremor rating scale, scale for the assessment and rating of ataxia, and beck depression Inventory (BDI).
Results: Results: 500 patients were assessed, 8 (1.6%) presented with MD and 12 (2.4%) with ataxia. The mean age of MD cases was 57.8±11.09 compared to 65.7±9.91 for cases without movement disorders. 70% of MD cases were >60 yrs, and 60% were males. Median MD NIHSS was 4 (3-6) compared to 7 (5-11) in non-movement disorders cases (P<0.001). The most common MD other than ataxia was tremor 4 (50%) secondary to brainstem, left and right thalamus, and right periventricular lacunar infarcts. 2 cases (25%) presented with left hemichorea secondary to right basal ganglia microbleeding and right caudate infarction. One patient (12.5%) had periodic right upper limb shaking with right subcortical watershed infarction, and one patient (12.5%) suffered palatal myoclonus following right middle cerebral artery infarction. Right ataxia accounted for 9/12 cases secondary to right cerebellar, right pontine, left periventricular, and left parathalamic infarctions. Left ataxia accounted for 3/12 cases secondary to right pontine, and right para thalamic infarctions. BDI showed mild degree in 30%, moderate in 25% and severe scores in 40%.
Conclusion: Conclusion: Movement disorders are rarely encountered in acute stroke associated with lesions inthalmus, caudate, brain stem and perventricular reions. Tremors are the most encountered after ataxia, NIHSS tend to be mild and depression is profound in such cases.
