The correct choice identifies that normal results from a Complete Blood Count (CBC) and Thyroid-Stimulating Hormone (TSH) test can help identify treatable causes of symptoms. These tests are used to rule out other medical conditions that could be contributing to cognitive decline or other dementia-like symptoms.

For example, anemia or infection can be detected through a CBC, while abnormalities in thyroid function can be assessed with a TSH test. If these tests return normal, it suggests that the symptoms are less likely to be due to these treatable conditions. This is crucial because certain medical issues can mimic or exacerbate symptoms of dementia, and addressing those might improve the patient’s overall health and cognitive function.

In contrast, confirming a diagnosis of Alzheimer's disease is not possible solely based on CBC and TSH results; a comprehensive assessment that includes clinical evaluation and cognitive testing is typically required. Similarly, these tests do not directly indicate the stage of dementia, nor do they provide information about cognitive improvement, which would involve tracking cognitive performance over time rather than relying on blood test results.
