Introduction:
Mild cognitive impairment (MCI) is a clinical syndrome that presents with memory disorders, normal general cognition, and no compromise of activities of daily living or dementia. Its diagnosis has important clinical implications, since it behaves as a possible predictor of cognitive disorders that would suggest the onset of dementia. Amnestic-type MCI is considered to be a stage prior to Alzheimer-type dementia. The prevalence of MCI varies from 1-29% and the existence of this diagnosis implies a risk of presenting dementia at 12% per year.
Aim:
To establish the prevalence of amnestic-type MCI in a group of persons over the age of 50 years from the Valle de Aburra.
Patients And Methods:
The sample was made up of 848 participants of both genders, over 50 years old, who lived in the metropolitan area of Medellin and had different socioeconomic and educational levels. Amnestic MCI was diagnosed according to the criteria proposed by the American Academy of Neurology.
Results:
Prevalence of amnestic MCI was 9.7%, and was more predominant in males (p = 0.01) than in females. The prevalence was significantly lower in the group with more than 12 years of schooling (p < 0.05), and no significant differences in the prevalence were found in relation to age or economic status.
Conclusion:
The prevalence of amnestic MCI, 9.7%, found in our study is within the range reported by other researchers.
Insights
The prevalence of amnestic mild cognitive impairment (MCI) in individuals over 50 in Valle de Aburra was 9.7%. This condition was more common in males and less common in those with over 12 years of schooling.
Area of Science:
- Neurology
- Epidemiology
Context:
- Mild cognitive impairment (MCI) is a predictor of dementia.
- Amnestic-type MCI often precedes Alzheimer's disease.
- MCI prevalence ranges from 1-29%.
Purpose:
- To determine the prevalence of amnestic MCI in adults over 50 in Valle de Aburra.
Summary:
- A study of 848 participants aged over 50 in Medellin found a 9.7% prevalence of amnestic MCI.
- Amnestic MCI was more prevalent in males (p=0.01).
- Higher education (over 12 years) was associated with significantly lower prevalence (p<0.05).
Impact:
- The study provides crucial epidemiological data on amnestic MCI in the Valle de Aburra region.
- Findings contribute to understanding MCI risk factors and demographics.
- Results align with global MCI prevalence ranges, aiding comparative research.
