Twenty-eight patients(19 men and 9 women,mean age 48.2 years)had MRI- confirmed thalamic stroke.Infarct was present in 22 patients and hemorrhage in 6.Eleven(39.3%)patients were younger than 45 years.In these young patients,cigarette smoking was the main risk factor associated with the development of stroke.In young patients,isolated and multiple thalamic lesions were present in almost equal proportions.The remaining 17 patients were older adults(45 to 84 years of age).In such patients,most lesions were multiple and were associated with atherosclerosis-predisposing factors.The main distinguishing clinical feature for hemorrhages and paramedian infarcts in comparison with infarcts in the other thalamic territories was the presence of an altered level of consciousness.No patient died as a direct result of the stroke.Thalamic stroke commonly occurs in young adults,and its mechanism is often undetermined.Increased awareness of this type of stroke in young adults should lead to better delineation of its clinical features,course,and management. |
