Overview
Head CT scan may be helpful in the diagnosis of the cause of amnesia. Structural and functional abnormalities are identified to detect any bleeding, stroke, tumor, atrophy or any changes suggestive of amnesia.
CT scan
- CT scan showed reduced blood flow to occipital lobe, caudate nucleus, and frontal lobe gray matter in patients suffering from post-traumatic amnesia. The blood flow was also observed to return back to normal once the memory is regained.[1]
- In dissociative amnesia there is no structural brain damage. CT scan looks normal. Although PET scan shows hypometabolism in areas responsible for autobiographical memory.
