  "gpt_diagnosis": "**Reasoning:** The patient shows significant elevations in T-tau and P-tau, along with moderately reduced Aβ, strongly suggesting Alzheimer's pathology. The MMSE score of 19 indicates cognitive impairment, while brain volumes are within normal ranges, ruling out significant atrophy as the primary cause.  \n**Diagnosis:** Dementia (likely Alzheimer’s disease)  \n**Confidence:** High",
