Mild Cognitive Impairment Disease Understanding
Mild Cognitive Impairment Overview
Mild Cognitive Impairment (MCI) is a transitional stage between normal cognitive aging and dementia, characterized by noticeable cognitive decline that does not yet interfere significantly with daily functioning. Individuals with MCI experience memory issues, attention deficits, and impaired judgment, making them more vulnerable to progressing into Alzheimer’s disease or other dementias.MCI’s growing prevalence, especially among aging populations, emphasizes the need for early detection and effective management strategies.
Mild Cognitive Impairment Diagnosis
Diagnosing MCI involves a comprehensive cognitive assessment, often including memory tests, attention evaluations, and other cognitive performance measures. Neurological exams, imaging, and biomarker analyses further confirm the condition and rule out other causes. Early diagnosis is essential, as it allows clinicians to monitor cognitive progression, assess the risk of developing dementia, and implement supportive interventions to help maintain cognitive function.Despite advancements in MCI diagnosis, significant unmet needs persist. Challenges due to the subtlety of early symptoms, which often overlap with normal aging or other neurological conditions. Cognitive testing alone may not capture MCI’s nuanced presentation, and even with imaging or biomarkers, distinguishing MCI from early-stage dementia remains difficult. Variability in symptoms and progression further complicates diagnosis, often delaying intervention. Additionally, a lack of standardized diagnostic criteria across medical practices limits consistency, making early and accurate identification challenging.
Mild Cognitive Impairment Epidemiology
For the purpose of designing the patient-based model for the MCI epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by, Total Diagnosed Prevalent Cases of Parkinson’s Disease, Total Diagnosed Prevalent Cases of Alzheimer’s Disease, and Total Diagnosed Prevalent Cases of MCI in the 7MM covering, the United States, EU4 countries (Germany, France, Italy, and Spain), United Kingdom, and Japan from 2020 to 2034.- In the assessment, the estimated total diagnosed prevalent cases of Parkinson’s disease in the US were nearly 1.21 million in 2023.
- Among European countries, Germany had the highest diagnosed prevalent cases of Alzheimer’s disease with ~1,491 thousand cases, followed by France, which had diagnosed prevalent population of ~1,170 thousand in 2023. On the other hand, the UK had the lowest prevalent population (620 thousand cases).
- In Japan, approximately 2.73 million diagnosed cases of MCI were identified, with around 103 thousand cases attributed to MCI due to Parkinson’s disease and 2.62 million cases due to Alzheimer’s. Projections suggest that by 2034, the prevalence of Alzheimer’s-related MCI will continue to grow and exceed that of Parkinson’s-related MCI, highlighting a trend that underscores the increasing impact of Alzheimer’s on the aging population.
- The analysis shows that, among the 7MM, the US accounted highest for the total diagnosed prevalent cases of MCI. There were nearly 4.22 million diagnosed prevalent cases of MCI in the US in 2023.Projections indicate that the UK is expected to continue leading in these figures by 2034.
KOL Views
To gaze into the epidemiology insights of the real world, we take KOLs and SMEs’ opinions working in the domain through primary research to fill the data gaps and validate our secondary research on disease prevalence.The analysts connected with 20+ KOLs to gather insights; however, interviews were conducted with 10+ KOLs in the 7MM. Centers such as the Boston University School of Public Health, Department of Epidemiology, US; Psychiatric Practice Bohlken, Berlin, Germany; Department of Biology, E´cole Normale Supe´rieure de Lyon, Lyon, France; Geriatric, Local Health Authority, Pistoia Italy, Department of Psychiatry, Universidad Autónoma de Madrid, Madrid, Spain; and Department of Occupational Therapy, Graduate School of Medicine, Akita University, Japan; and others were contacted. Their opinion helps understand and validate current disease prevalence, gender involved with the disease, diagnosis rate, and diagnostic criteria.
