3.

An EEG will always appear abnormal if the brain is functioning abnormally?
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Although acute, severe, and anatomically large abnormalities of the brain are likely to cause EEG abnormalities, normal EEG's may be seen in cases with small lesions or in others with long-standing, mild and limited cerebral abnormalities.
