Decorticate Posturing Unilateral
However they may be seen with either unilateral or bilateral pathology rostral to the brainstem as well.
Decorticate posturing unilateral. This asymmetry has some localising value fig 3. Due to structural lesions of the thalamus internal capsule or cerebral white matter. 1 it is a clinically useful lateralizing sign particularly when complex partial seizures do not generalize version and focal clonic movements are good lateralizing signs for complex partial seizures becoming generalized.
Posturing is frequently observed in patients who are comatose following traumatic brain injury but may also arise in patients with various metabolic derangements. However this is not as serious as decerebrate posture wherein the particular kind of posturing appears on both sides of one s body. It is always contralateral to the side of the predominant ictal discharge which is generally the side where the seizure started.
