Alzheimer’s disease is emerging as one of the most pressing healthcare challenges in ageing populations worldwide. It progressively impairs memory, cognition, behaviour, and the ability to perform everyday activities, while placing a substantial emotional, social, and economic burden on patients, carers, and healthcare systems. Together, these impacts underscore the urgent need for more effective treatments, stronger support structures, and sustainable long-term care strategies.
According to the WHO, more than 55 million people globally are living with dementia, with nearly 10 million new cases reported every year. While available therapies can help manage symptoms, medication adherence remains a major challenge in Alzheimer’s care.1, 2
Factors such as cognitive decline, swallowing difficulties, complex dosing routines, and carer dependency can interfere with treatment consistency and patient outcomes, driving the need for innovative and patient-centred formulation approaches to improve long-term disease management. 3
Alzheimer’s disease is a progressive neurodegenerative disorder that gradually damages brain cells, leading to a decline in remembering, memory loss, thinking ability, and overall cognitive function.4 It is the most common form of dementia and primarily affects older adults, although early-onset cases can also occur.5 The disease develops slowly over time, interfering with a person’s ability to perform daily activities independently 4.
Symptoms are generally mild, and individuals may still function independently with limited support. Common early-stage symptoms include mild memory loss, difficulty remembering recent conversations or appointments, trouble finding the right words, occasional confusion, and slight changes in mood or decision-making abilities.
Memory impairment and behavioural changes become more significant, often requiring increased carer assistance.
Individuals may lose the ability to communicate effectively, recognize loved ones, or perform essential daily activities such as eating, dressing, and personal hygiene.
According to the WHO, dementia currently affects more than 55 million people worldwide1, with Alzheimer’s disease being the most common form of dementia.
The progression of Alzheimer’s disease has a profound impact on daily functioning and independence, affecting not only patients but also carers and families. As cognitive abilities decline, patients become increasingly dependent on long-term care and continuous medical support, making effective disease management and treatment adherence essential for maintaining quality of life.6
Alzheimer’s disease and dementia continue to place a growing burden on the UK healthcare system, economy, caregivers, and wider society. With an aging population and increasing life expectancy, the number of people affected is expected to rise significantly over the coming decades.
The rapid growth in dementia cases is strongly linked to the UK’s aging population. As life expectancy increases, healthcare systems are expected to face greater pressure in diagnosis, long-term care, and support services.
Dementia represents one of the UK’s costliest health conditions, with rising demands on healthcare services, social care systems, and unpaid caregiving support.
The burden of Alzheimer’s disease extends far beyond patients, significantly affecting families and unpaid carers who provide long-term emotional, physical, and financial support.
These growing statistics highlight the urgent need for improved awareness, early diagnosis, effective treatment strategies, and better medication adherence approaches to reduce the long-term burden of Alzheimer’s disease across the UK.
Alzheimer’s disease remains one of the most complex neurological disorders to manage, primarily because there is currently no definitive cure available. Most existing treatment approaches focus on symptom management and temporarily slowing cognitive decline rather than reversing disease progression.9
Another major challenge is the limited efficacy of currently approved Alzheimer’s medications, as treatment responses can vary significantly between patients. While some individuals may experience temporary cognitive stabilisation, others may show minimal improvement or develop side effects that affect long-term adherence.9
Late diagnosis further complicates treatment outcomes, as many patients are diagnosed only after significant brain damage and cognitive decline have already occurred. This reduces the overall effectiveness of available therapies and limits opportunities for early intervention.10
Managing Alzheimer’s disease also requires long-term therapy and continuous caregiver involvement, making treatment routines increasingly complex as the disease progresses. Medication schedules, behavioural symptoms, comorbid conditions, and declining patient independence all contribute to challenges in maintaining consistent and effective care.
Many elderly Alzheimer’s patients experience swallowing difficulties, also known as dysphagia, which can make conventional tablets and capsules difficult to take consistently. Swallowing problems are more common in older adults and can interfere with proper medication administration.12 3
Memory loss and cognitive decline are among the primary reasons why Alzheimer’s patients struggle with medication adherence. Patients may forget doses, take medications multiple times, or become confused about treatment schedules, especially as the disease progresses.
According to the Alzheimer’s Association Alzheimer’s Symptoms, memory impairment and confusion significantly affect daily functioning and routine management.13
Many Alzheimer’s patients also manage multiple chronic conditions, leading to complicated medication schedules and polypharmacy. Frequent dosing requirements can increase the likelihood of missed or incorrect doses.3
Complex treatment regimens is a major barrier to medication adherence in chronic diseases.3
As Alzheimer’s disease management continues to evolve, there is a growing shift toward patient-centred formulation design that focuses not only on therapeutic effectiveness but also on improving medication adherence and overall patient experience. Since many Alzheimer’s patients struggle with memory impairment, swallowing difficulties, and complex treatment routines, innovative drug delivery approaches are becoming increasingly important in long-term disease management.
Traditional oral tablets can present significant administration challenges for elderly patients, particularly those experiencing dysphagia, cognitive decline, or reduced independence. This has accelerated the development of alternative dosage forms designed to simplify treatment administration and improve compliance.
ODTs simplify the medication-taking process, especially for patients with cognitive impairment or reduced motor coordination.
Their convenience can help reduce resistance to medication intake and support more consistent therapy management.
Improving medication adherence remains a critical step toward achieving better long-term outcomes in Alzheimer’s care. Smarter and patient-friendly formulations can help support more consistent dosing, reduce administration challenges, and improve treatment continuity.
Simplified dosage forms such as ODTs may also help reduce caregiver burden by making medication administration easier for elderly patients with cognitive decline or swallowing difficulties.15
Better adherence and treatment consistency can contribute to improved patient comfort, enhanced quality of life, and potentially better therapeutic outcomes in long-term disease management.
Novumgen continues to focus on innovative and patient-centred pharmaceutical solutions designed to support better treatment accessibility, convenience, and long-term adherence.
With growing recognition of swallowing difficulties and administration challenges in elderly patients, advanced oral dosage forms such as ODTs are becoming increasingly important in improving patient experience and treatment continuity.
