Current Scenario of the Alzheimer's Disease Market

Alzheimer's disease (AD) is the most natural cause of progressive dementia in the elderly. There has been an exponential increase in the frequency of Alzheimer's disease cases globally, stressing the need to develop an effective treatment to cure it. Alzheimer's is a neurological disease affecting an individual's memory, thinking, and behavior. The traits usually worsen over time to the extent of the inability to perform daily tasks. Alzheimer's disease (AD) is one of the most widespread dementias in the world. According to the facts and figures of the Alzheimer's Association, every 33 seconds, a new case of Alzheimer's disease occurs. At a very high stage, millions of patients are suffering. Eventually, the improvement in technology regarding AD and neurodegenerative conditions is becoming significant. Unfortunately, 10-20% of AD diagnoses are inaccurate. To overcome this hurdle. Alzheimer's disease is a degenerative and progressive disease that attacks the nerve cells, which results in the loss of memory, behavioral changes, and changes in thinking and language skills. There is fast growth in the number of people living with Alzheimer's disease, with around one individual in four diagnosed with this disease.


The growing number of patients with Alzheimer's and neurodegenerative diseases, the increasing aging population, growing investments for R&D, and improved life expectancy of the general population are propelling the Alzheimer's disease market. 

In addition, the YOY rise in the geriatric population and the growing prevalence of chronic diseases such as dementia are promoting the growth rate of the Alzheimer's disease market. Furthermore, increasing the channels for drug development and investing in biomarkers also fuel the growth rate of the Alzheimer's disease market. In addition, growing innovative diagnostics for early diagnosis, more specific drug development, and increased life expectancy in the general population drive the global Alzheimer's disease market. According to the United Nations's Global Population Prospects 2019, by 2050, one in every six inhabitants will be over 65, up from one in every eleven in 2019. Furthermore, the market is expected to expand due to increased clinical studies on diagnosing and treating Alzheimer's.

The other factors anticipated to promote the growth of the Alzheimer's disease market are the increasing occurrence of chronic diseases like dementia, increasing channel drug development, venture into biomarkers for drug development, and increasing advanced diagnostics for early detection and more specific drug development. In addition, very few therapeutic options are on the market, and none offer a complete remedy for this condition. Hence, entry into the market would provide lucrative growth prospects to the market participants.


However, a shortage of surrogate indicators for drug discovery and production, inadequate testing resources, and long, unpredictable procedures are expected to hamper the growth rate of the global Alzheimer's disease market. With the rising number of people impacted, Alzheimer's disease is becoming a significant public health issue. Alzheimer's disease affects 5.3 million Americans and 35 million individuals globally. New treatments for diagnosing and treating Alzheimer's disease are desperately needed as the disease progresses worldwide. However, since the signs are mild and the anatomical changes in the brain and central nervous symptoms are not often evident by medical scans, early diagnosis of Alzheimer's disease (AD) is complex, and the early symptoms of Alzheimer's disease (AD) are often ignored. This restriction has severe consequences because late-stage diagnosis provides patients only symptomatic relief alternatives through drugs, reducing the potential advantage that may have been achieved through early medication and diagnosis. As a result, shortcomings in early-stage AD diagnosis restrict the global development of the Alzheimer's disease market.

Alzheimer's Disease Market By Therapeutics

Due to a large user base, the marketed drugs segment is predicted to lead the global market based on therapeutics during the forecast period. Additionally, Cholinesterase inhibitors have the largest market share and are expected to witness a CAGR of 6.8% during the forecast period. Cholinesterase inhibitors have higher efficiency in the treatment of Alzheimer's. These drugs help promote communication between nerve cells with higher concentrations of acetylcholine, which temporarily stabilizes symptoms of dementia. Donepezil is the most widely prescribed cholinesterase inhibitor, which has been approved to treat all stages of Alzheimer's disease. Most physicians and patients consider cholinergic drugs useful as the US FDA approves them. In addition, several clinical trials are ongoing on cholinesterase inhibitors to increase drug efficacy and decrease adverse effects. Therefore, the cholinesterase inhibitor drug market will grow during the forecast period due to recent developments.

NMDA Receptor Antagonists are another class of drugs anticipated to grow profitably under this segment. N-methyl-D-aspartate receptor antagonists effectively help the patient with Alzheimer's disease because of which the patient suffers from brain damage, memory loss, and possibly death. They help with the strong depolarization of the postsynaptic membrane to attenuate channel blockade by Mg2+, activating the drug action. In addition, the wide range of availability of drugs such as dextromethorphan, opioids methadone, ketobemidone, ketamine, memantine, dextropropoxyphene, and amantadine is further driving the growth of the segment.

Alzheimer's Disease Market  By Diagnostics

Among all the segments, the CT scan segment is estimated to dominate the global Alzheimer's disease market during the forecast period. The absence of an alternative imaging tool for brain and neurological diagnostics is crucial for its large share. Being the most common type of brain scan, computed tomography is used in the diagnosis of dementia and dementia-like symptoms, which helps in ruling out other conditions that cause changes in brain structure because of Alzheimer's disease. This system of brain imaging help in diagnosis that explains dementia by allowing doctors to see changes in brain structure and its functioning. Brain loss associated with Alzheimer's disease and the formation of abnormal levels of amyloid plaques in the affected Region of the brain is detected using computed tomography. Thus, it helps in the growth of the segment.

The MRI segment is expected to hold a significant share of the global market during the forecast period owing to the ability of an MRI machine to reveal the parts of the brain getting smaller and the effect of different diseases on the brain. In addition, it helps researchers to find out the consequences of dementia, its different types, and the results of treatments, revealing the way patients respond.

Positron emission tomography, or a PET scan, is predicted to grow at a healthy CAGR over the forecast period, being a painless and non-invasive procedure that measures the build-up of one of the hallmarks of Alzheimer's disease, abnormal amyloid proteins in the brain. It removes the extra procedures and reduces the number of scanning sessions a patient needs to complete, taking only about 30 minutes. Further, it provides better imaging data, which increases patient comfort. Such factors are foreseen to drive the growth of the global Alzheimer's disease market under this segment over the forecast period.


Geographically, the North American Alzheimer's disease market currently commands a significant share of the global market. It is expected to sustain its stronghold in the future, owing to the growing prevalence of Alzheimer's disease and extensive technological developments in the Region. The United States holds the largest share of the global Alzheimer's disease market. The United States is the worldwide leader in Alzheimer's disease intervention and management. Numerous biopharmaceutical companies operate in America cumulatively, with 85 drugs for combating Alzheimer's disease in various pipeline stages.

  • In Dec 2022, Cognition Therapeutics became the first participant to receive a dose in Europe after the Phase 2 SHINE clinical trial of Oral CT1812 in Alzheimer's disease patients. This led to its expansion in clinical sites in the Netherlands, Spain, and the Czech Republic. This once-daily oral capsule has been developed for treating mild to moderate Alzheimer's disease by modulating a critical cellular receptor, sigma-2, to block the binding of oligomers to neurons. This new mechanism of action results in the prevention of their synaptotoxic effects.

  • In November 2022, the successful results of Eisai's significant global confirmation Phase 3 Clarity AD clinical study of lecanemab were announced by Eisai Co., Ltd., and Biogen Inc., which was used for the treatment of cognitive impairment in Alzheimer's disease. In addition, this investigational anti-amyloid beta protofibril antibody for severe and mild Alzheimer's disease with amyloid pathology in the brain has been showcased at the Clinical Trials in Alzheimer's disease conference in San Francisco.

  • In November 2022, Eli Lilly and Company shared positive donanemab data, which met all primary and secondary endpoints during the first active comparison study in early symptomatic Alzheimer's disease for the 6-month primary outcome analysis in the Phase 3 TRAILBLAZER-ALZ 4 study. The FDA's accelerated approval pathway provided the first active comparison data on amyloid plaque clearance to patients with early symptomatic Alzheimer's disease. The beta-amyloid plaque reduction biomarker recognized by FDA has treated patients with amyloid-targeting therapies with a reasonable likelihood of predicting clinical benefit. This helps in treating early-onset Alzheimer's disease, preventing its further stages, and assessing superiority in reducing amyloid plaque.
  • In a recent study in Dec 2022, hundreds of participants were recruited by researchers in China to study biomarkers of Alzheimer's disease with healthy cognition or dementia for its early detection by focusing on urinary formic acid. With the hope of finding affordable and accessible early detection tests for Alzheimer's disease, scientists have checked the participants' formic acid levels since its higher levels in urine may indicate cognitive impairment, per the researcher's findings.
