If a patient exhibits atrophy of the cerebral cortex, elderly individuals generally do not show clinical symptoms of dizziness. The main manifestations are cognitive impairments, such as a decline in memory, computational ability, and judgment, as well as decreased executive functions. Some severe cases may even show personality changes and exhibit mental symptoms. If the patient has significant cerebellar atrophy, it is possible for them to experience dizziness, such as in cases of multiple system atrophy causing cerebellar atrophy, where the elderly may notably suffer from dizziness, which is related to changes in body position, particularly making them prone to dizziness when standing.
