Diagnostic methods for<unk>  include physical examination, blood pressure measurement, blood sampling, ECG, EEG, chest X-ray, urinalysis, arterial blood gas analysis, and imaging of the head (CAT scan and/or MRI). Since decreasing blood pressure is essential, anti-hypertensive medication is administered without awaiting the results of the laboratory tests. Electroencephalographic examination detects the absence of alpha waves, signifying impaired consciousness. In people with visual disturbances, slow waves are detected in the occipital areas.
