Alzheimer’s Disease Understanding

Alzheimer’s Disease Overview

Alzheimer’s disease is a progressive, irreversible neurological disorder, primarily impacting memory, reasoning, and cognitive abilities. It is the leading cause of dementia, responsible for roughly 60-80% of all cases. Though often emerging in the mid-60s, early-onset Alzheimer’s can affect individuals as young as their 40s or 50s, albeit rarely. Initial symptoms commonly include memory loss that significantly interferes with daily life, followed by confusion, language difficulties, impaired judgment, and behavioral changes. The disease’s exact cause remains unknown, but it is associated with abnormal accumulations of Amyloid Beta protein plaques and tau protein tangles in the brain, which disrupt cellular communication and lead to cell death. Increasing age and family history are recognized as key risk factors for Alzheimer’s disease.

Alzheimer’s Disease Diagnosis

Diagnosing Alzheimer’s disease remains challenging due to its gradual onset and overlapping symptoms with other cognitive disorders. The diagnosis primarily relies on clinical assessments, including a detailed medical history, cognitive tests, and evaluations of memory, reasoning, and language skills. Neuroimaging techniques, like MRI and PET scans, help detect structural brain changes, while biomarkers in cerebrospinal fluid can reveal amyloid and tau protein abnormalities. However, definitive diagnosis often occurs post-mortem through brain tissue examination.

The complexity of Alzheimer’s disease diagnosis is compounded by variability in symptom progression and the absence of a single diagnostic test. Additionally, the need for specialized tools and resources makes early diagnosis difficult, especially in low-resource settings. Misdiagnosis risks are high, which can delay appropriate interventions and add stress for patients and caregivers. Improved diagnostic accuracy through advancements in biomarker research and neuroimaging is critical to enabling timely, targeted treatments and addressing these diagnostic challenges in Alzheimer’s disease.

Alzheimer’s Disease Epidemiology

For the purpose of designing the patient-based model for Alzheimer’s Disease, the report provides historical as well as forecasted epidemiology segmented by Total Diagnosed Prevalent Cases of Alzheimer’s Disease, Gender-specific Diagnosed Prevalent Cases of Alzheimer’s Disease, Age-specific Diagnosed Prevalent Cases of Alzheimer’s Disease, Severity-specific Diagnosed Prevalent Cases of Alzheimer’s Disease, Diagnosed Prevalent Cases of Agitation in Alzheimer’s Disease, and Diagnosed Prevalent Cases of Psychosis in Alzheimer’s Disease in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain) and the United Kingdom, and Japan, from 2020 to 2034.

The analyst'sanalyst estimate that approximately 15.83 billion Diagnosed Prevalent Cases of Alzheimer’s disease were found in 2023 in the 7MM.

In 2023, the United States accounted for about 44% of diagnosed Alzheimer’s disease cases across the 7MM, totaling 6.98 million cases. The analyst forecasts a rise in this figure by 2034, reflecting the growing burden of the disease. This trend underscores the increasing healthcare challenge posed by Alzheimer’s in the US during the forecast period.

In the assessment, the estimated total diagnosed prevalent cases of Alzheimer’s disease in Japan were nearly 3.92 million in 2023.

In 2023, Japan recorded nearly 1.39 million diagnosed cases of Alzheimer’s disease in males and 2.53 million in females, reflecting a clear gender difference in disease prevalence. This disparity underscores the importance of considering gender-specific factors when addressing Alzheimer’s disease, including tailored treatment and care strategies for male and female patients.

Age-specific cases in the US are categorized into four groups: under 65, 65-74, 75-84, and 85+ years. In 2023, the 75-84 age group held the highest prevalence with nearly 2.79 million cases, whereas the under-65 group recorded the lowest with nearly 175 thousand cases.

Alzheimer’s disease is also classified by severity: mild cognitive impairment (MCI), mild, moderate, and severe dementia. Within EU4 and the UK, the MCI stage had the highest prevalence with around 2.56 million cases in 2023, while severe dementia showed the lowest with 645 thousand cases.

In 2023, the United States documented approximately 5.23 million diagnosed cases of agitation linked to Alzheimer’s disease, with projections indicating a continued rise by 2034. This growing prevalence highlights the escalating need for targeted interventions to manage agitation symptoms in Alzheimer’s patients, addressing both psychological and behavioral aspects of the disease.

In Japan, approximately 2.03 million cases of psychosis related to Alzheimer’s disease were reported in 2023, with the number expected to increase in the coming years. This upward trend emphasizes the growing burden of Alzheimer’s disease-associated psychosis and the need for effective treatments to manage these complex symptoms within the Japanese population.
