Insights
The International Classification of Diseases, 10th Revision (ICD-10) criteria for vascular dementia are highly selective, with only 24.6% of patients meeting the criteria. Subtypes like multi-infarct dementia were most common.
Area of Science:
- Neurology
- Geriatrics
- Clinical Diagnostics
Background:
- Vascular dementia is a significant cause of cognitive decline.
- Accurate diagnostic criteria are crucial for patient management and research.
- The International Classification of Diseases, 10th Revision (ICD-10) provides diagnostic guidelines for vascular dementia.
Purpose of the Study:
- To assess the clinical feasibility and application of ICD-10 criteria for diagnosing vascular dementia subtypes.
- To determine the proportion of patients with vascular lesions on CT scans who meet ICD-10 criteria for vascular dementia.
Main Methods:
- A study involving 61 demented patients with CT-confirmed vascular lesions.
- Evaluation of patient data against ICD-10 diagnostic criteria for vascular dementia.
- Classification of fulfilled cases into specific vascular dementia subtypes.
Main Results:
- Only 15 patients (24.6%) met the ICD-10 criteria for vascular dementia.
- Among those meeting criteria, 66.6% could be classified into subtypes.
- Multi-infarct dementia and subcortical vascular dementia were the most frequently identified subtypes.
Conclusions:
- The ICD-10 criteria for vascular dementia appear more selective than traditional 'ischaemic scales'.
- Clinical application of ICD-10 criteria in this cohort yielded a low fulfillment rate, suggesting a need for careful diagnostic consideration.
Abstract:
The clinical feasibility of the ICD-10 criteria for subtypes of vascular dementia were examined in an investigation of 61 demented patients (74.4, SD 8.2 years) showing CT appearances of vascular lesions. Only 15 cases (24.6%) fulfilled the ICD-10 criteria of vascular dementia. Of these cases, 66.6% could adequately be classified in subtypes. The most frequent types of vascular dementia were multi-infarct dementia and subcortical vascular dementia. Our findings suggest that the ICD-10 criteria of vascular dementia are more selective than the classical 'ischaemic scales'.
