Help my wife had a head ct done because of her getting dizzy and the it said advanced mild to moderate cerebral atrophy in the frontal temporal lobe what does it mean?

Loss of brain cells: Cerebral atrophy is a loss of brain cells or neurons and their connections. Some atrophy occurs naturally with aging but more rapid loss is seen with dementia or with a stroke. The frontal and temporal lobes are especially involved with mood and emotions and less so with motor activity. Cerebral atrophy is a non specific finding and does not explain dizziness.

This may or may not clinically correlate with cognitive change, and if so, might be an early sign of a neurodegenerative process. Alternatively, this may represent a sign of normal aging. Suggest seeing an otolaryngologist regarding the dizziness. If a question of an early dementia, a PET scan would be the best test by far.
