My husband had a CT scan of head and they said there is too much white matter for a person of his age. he is 56. he had an espisode where his vision did strange things and sort of an altered mental status. That is what they said when they ordered the CT Scan
White matter change of this kind is unusual for 56 yrs old male. How about his memory and daily functions....? U have mentioned an episode of transient altered behavior. .....this may be a complex partial seizure.... Get his MRI brain done and also consult a neurologist and get his cognitive assessment done. Regards.
