Overview

Certain studies, such as electroencephalography (EEG), are of noticeable importance. These tests are done to exclude other diseases and aid in the diagnosis of certain conditions.

Other Diagnostic Studies

Electroencephalogram (EEG)

  • It is mainly used in confusion to rule out absent seizures. Absent seizures lack motor symptoms and they present with a staring gaze. EEG helps in differentiating those seizures from confusion.
  • It can help in diagnosing associated co morbid conditions like certain metabolic encephalopathies.
  • Metabolic encephalopathies show slow wave high amplitude waves.
  • Hepatic encephalopathies and septic conditions present with a triphasic wave.
  • Most psychiatric conditions have a normal EEG which helps in differentiating those symptoms from confusion proper.
