A diagnosis of depression clearly recorded by a clinician in the electronic medical record at baseline (based on structured or unstructured diagnostic documentation formed through routine clinical practice).
Complete baseline electronic medical record data available, including at least demographic information (age, sex), clinical diagnoses, comorbidities, and medication records.
At least one follow-up record available in the electronic medical record system to enable determination of incident dementia outcomes.
Informed consent provided for the use of routine medical data for this research analysis.
You may not be if
Any type of dementia diagnosis recorded in the electronic medical record at baseline (including Alzheimer's disease, vascular dementia, and other types of dementia).
Medical record documentation indicating that the diagnosis of dementia preceded the diagnosis of depression, or an inability to clearly determine the chronological order of the two diagnoses.
Presence of other neurological diseases at baseline that may independently cause severe cognitive impairment (e.g., Parkinson's disease, multiple sclerosis, brain tumor, normal pressure hydrocephalus).
Missing key baseline electronic medical record data that would preclude subsequent risk model analysis.
Incomplete follow-up information or inability to clearly confirm incident dementia outcomes through the electronic medical record system.
Refusal to participate in the study or withdrawal of informed consent.
