Early Detection and Diagnosis of Alzheimer's Disease Is Important

Early Signs of Alzheimer's

Early detection and diagnosis of Alzheimer's disease is becoming both more important and easier. 

Dementia is a syndrome that may be caused by a number of different diseases the most prevalent of which is Alzheimer’s disease. It is generally accepted that Alzheimer’s is responsible for around two thirds of all dementia diagnoses.

With the realization that urgent action must be taken to reduce the burden of Alzheimer’s disease, a condition with escalating costs and very limited treatment options, there has been a shift in focus to identify individuals much earlier in the disease process. Not all individuals with mild cognitive impairment will develop dementia and despite there being no current treatment to prevent or cure the disease, there is an urgent need to improve diagnosis rates so that those at greatest risk can be identified early and measures implemented to reduce or prevent further progression.

The progression of Alzheimer’s disease can be broken down into three general stages: preclinical, mild cognitive impairment, and dementia, but can be more accurately described according to a 7-Stage model.

While there is currently debate amongst specialists whether mild cognitive impairment (MCI) is truly a diagnosis, what is acknowledged is that people with MCI have a higher risk of developing Alzheimer's in the future than those people without MCI.

It is estimated that around 30% of individuals with MCI will develop Alzheimer's. Another 30% will remain with mild cognitive impairment, and 30% will experience improvement of symptoms. (Reference 1)

Getting an Alzheimer’s diagnosis early - when symptoms have started but are still mild — offers several advantages. You may be a candidate for medication that can lessen symptoms and slow progression of the disease. An early diagnosis also allows families to take time to understand the disease, know what to expect, learn how to adapt and cope, and gain access to resources. All of this can make it easier to manage Alzheimer’s symptoms. An early diagnosis also may allow you to participate in clinical trials of potential new treatments. (Reference 2)

Key Benefits of Early Detection

  • Access to Treatments: Early intervention allows patients to receive disease-modifying therapies that can delay the progression of cognitive decline and lessen symptoms.

  • Reversible Causes: Not all memory loss is Alzheimer's. An early check-up can rule out or treat other conditions with similar symptoms, such as vitamin deficiencies, thyroid disease, or depression.

  • Future Planning: Patients can actively participate in their own legal, financial, and healthcare decisions while they are still capable of doing so.

  • Lifestyle & Safety Adjustments: Early knowledge empowers families to prepare for potential safety issues (like wandering or driving) and access vital local support resources.

  • Clinical Trial Opportunities: Diagnosed individuals often qualify for clinical trials investigating new, breakthrough treatments.

  • Cost Savings: Early diagnosis can collectively save billions in medical and long-term care costs by extending the time patients can live independently at home
