  "gpt_diagnosis": "**Reasoning:** The patient shows moderate Aβ reduction and significant elevation in T-tau and P-tau, which are biomarkers consistent with Alzheimer's pathology. The MMSE score of 23 suggests mild cognitive impairment, while brain volumes remain within normal ranges.  \n\n**Diagnosis:** **Mild Cognitive Impairment (MCI) due to Alzheimer's disease**  \n**Confidence:** **High**",
