BOF 2
When faced with neurological investigations, all are true, except:
1- the predominant Rhythm of the EEG in a healthy young man is the alpha rhythm
2- the alpha rhythm on EEG disappears upon eye closure or mental thinking
3- the EEG is usually normal in 50% in the interictal phase of epileptics
4- the normal motor conduction velocity in the upper limbs is 50-60 meter/ second
5- the EMG is characteristically abnormal in metabolic myopathies

Answer 5
Remember, the word EEG does not mean Epilepsy, and EEG is not used in the diagnosis of Epilepsy although it is the most sensitive investigation in epilepsy …….so for more details …see neurology books.
Metabolic myopathies usually have normal EMG e.g. in hypokalemic weakness, there are no characteristic changes on EMG testing
