Risk Factors for the Progression of Mild Cognitive Impairment in Different Types of Neurodegenerative Disorders

الملخص EN

Objective.

Mild cognitive impairment (MCI) is a transitional state between normal aging and early dementia.

It has a heterogeneous etiology and clinical course.

This study aimed to examine the factors associated with the progression of MCI in different types of dementia disorders.

Method.

A retrospective, longitudinal, observational study of outpatients with MCI was conducted at a medical center in northern Taiwan.

Patient medical records were reviewed, and risk factors were analyzed by multivariate analysis.

Results.

Among 279 patients with MCI, 163 (58.4%), 68 (24.4%), and 48 (17.2%) were diagnosed with Alzheimer’s disease, vascular cognitive impairment, and Lewy body diseases, respectively.

During the observation period, 37.2% of patients progressed to dementia.

Older age and a higher Clinical Dementia Rating Scale-Sum of Boxes were associated with the risk of progression.

Hyperlipidemia was associated with a decreased risk.

Converters were more likely to receive an antidementia prescription.

Conclusion.

Our study suggests the importance of comprehensive clinical profiling, risk factor assessment, and detailed drug history evaluations in improving our understanding and management of dementia subtypes.
