Some degree of cerebral shrinkage occurs naturally with the dynamic process of aging. [3] Structural changes continue during adulthood as brain shrinkage commences after the age of 35, at a rate of 0.2% per year. [4] The rate of decline is accelerated when individuals reach 70 years old. [5]
These include; the patient's age, acuity of their signs and symptoms, associated neurological conditions, and family history of hereditary forms of cerebellar degeneration. [3] A diagnosis for cerebellar degeneration is regarded after any of the aforementioned signs and symptoms surface.
The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
Brain volume continues to decrease as we age—including the frontal lobe and hippocampus, the areas responsible for cognitive functions—with the rate of shrinkage increasing by around age 60.

An overlap between symptoms can occur as the disease progresses and spreads through the brain regions. [14] Structural MRI scans often reveal frontal lobe and/or anterior temporal lobe atrophy, but in early cases the scan may seem normal. Atrophy can be either bilateral or asymmetric. [13]
