The correct answer highlights that the behavior exhibited by Brooke—specifically, her difficulty in making desserts and forgetting her recipes—can be indicative of cognitive decline associated with Alzheimer's disease. Alzheimer's is characterized by memory loss and impaired cognitive function, which often leads to difficulties with familiar tasks such as cooking or following recipes. This change in Brooke's ability to perform tasks she once managed easily could suggest a progression of cognitive impairment typical in Alzheimer's.

The other options represent different issues: delirium is typically a temporary and acute disturbance in mental function, apraxia refers to the inability to perform certain purposive actions even though the individual may have the desire and physical capability to do so, and normal aging generally does not involve such significant memory issues. Instead, normal aging may lead to a slower processing speed or occasional forgetfulness, but not typically to the extent that tasks like baking become completely unmanageable. Thus, the nature and severity of Brooke's difficulties align more closely with the symptoms of Alzheimer's disease.
