Brookinsky’s sign is a test that is used to diagnose a number of diseases of the brain, more commonly encephalitis, meningitis, subarachnoid hemorrhage, and increased intracranial pressure, to name a few. The test is performed by placing the patient on his or her back, straightening the legs, and then flexing the neck. If the Bruschi sign is positive, the patient’s two lower limbs will be flexed and the legs will be contracted. It is necessary to actively improve the MRI of the skull to clarify the condition and actively treat it.
