Subject: Medicine
A 40 year old man presents with sporadically occurring behaviour automatisms and olfactory hallucinations. Which one of the following is the most likely diagnosis?

Correct Answer : D.

Olfactory hallucinations are related to lobe lesions throughout the entire brain, though mainly to the temporal lobe. Complex automatic behaviorisms are related to lesions of the temporal lobe.
Visual hallucinations (formed images) are related to lesions of the posterior temporal lobe or amygdala-hippocampus. Visual hallucinations (unformed images) are related to lesions of the occipital lobe.
