Why technology-enabled care is essential to reduce the care gap
Andrew Davies, CEO of RWG Mobile, discusses how preventing long-term conditions through technology-enabled care is essential to reducing the care gap.
The COVID-19 pandemic changed not only the way we live our day-to-day lives, but the way we view and use healthcare.
The belief that the best care was provided face-to-face and involved a mandatory walk to the doctor’s surgery had to be reevaluated – care could now be provided online, in our homes, and it did not need us to go anywhere.
The advance and, above all, the acceptance of digital has naturally led to the question: what now? What path must healthcare and social care take to remain sustainable, practical, and compassionate for both short-term patients and people with chronic illnesses?
Tech advancement has been profound on so many levels, especially when it comes to sensors – home blood pressure monitors and pulse oximeters, single-lead home ECG devices – used to check sinus rhythm and atrial fibrillation – glucose monitoring, and of course – smartwatches.
Medical wearables are all around us facilitating, to an extent, remote monitoring. But what is the missing link between advanced sensor tech and true digital care?
The answer is integration. It is essential for caring organisations to implement technology-assisted care to address the care gap and reduce the likelihood of preventable long-term chronic and debilitating conditions – especially within the population of older people.

Despite the proliferation of tech sensors that facilitate monitoring, the lack of an integrated care platform is a setback to achieving digital care that extends older people’s independence.
Single point applications are useful in gathering data. However, they fail to pull it all together and support medical professionals in drawing a holistic picture of the service user’s health.
Technology can notice and measure a change in a person’s behaviour but can’t account for other factors that may be affecting their daily routine: for example if they are ill, or just feeling a bit low or lonely.
That’s why there is a need for an integrated platform that can contribute to monitoring, analysing, and improving the well-being and independent living of the ageing population.
In order to achieve that connected network, that integration, healthcare and social care need to embrace a new kind of digital platform: one that brings together all the information from sensor tech and generates insights that in turn help power new workflows and interventions.
Not only will it provide masses of specialised data, it will connect the cared-for, the carers and the kinship carers (family and friends) – everyone gets to sit at the table and improve communication between all parties.
The generic term for this is Health-Platform-as-a-Service (HPaaS) – and this is the direction innovative healthcare must head for.
Falls and fall-related injuries class as a common and often serious problem for older people.
In England alone in 2021, there were more than 216,000 emergency hospital admissions in the 65+ age group. The annual costs for addressing these falls and resulting injuries for the NHS is estimated at £2.3b.

Let’s play through some scenarios to see how an integrated platform can enable reactive and proactive treatments.
Imagine that a vulnerable person has a fall at home, a sensor can detect the fall and the platform can automate action.
A first step might be to initiate a video call with a carer, popping up a familiar face on a standard TV set. The next might be a call to a paramedic or securing physical help from friends and neighbours. Then, the professional carers can analyse the data collected before, during, and after the fall to find the cause for the fall – maybe low blood sugar or abnormal blood pressure?
Our conversations with medical professionals have also indicated the need for proactive technology – one that anticipates and prevents crises.
Movement sensors, locations awareness technology, collection of patterns, such as understanding heating and lighting behaviours, supplementary information from wearables including heart rate, oxygen levels and blood sugar levels and pop-up quizzes about mood and medication can be collected and analysed with the help of AI to portray a detailed wellness picture of the cared-for individual.
Actions can then occur – prompt a video call from a professional or family member, for example. That could not only help individuals with their medical conditions, but will provide a way to combat loneliness – a serious and challenging problem for elderly people who live independently.
Health platforms provide a unique service: it’s a connected care community, where people are taken care of digitally, but are simultaneously provided with means to communicate with kinship carers and participate in social events organised by professional carers.
It is vital that remote patient management technology must enable support for people in the community to self-manage their long-term health conditions to achieve the best outcomes for their health and well-being and to reduce the care gap.
Health platforms are a valuable toolbox that brings remote care to another level.
An Alzheimer’s mutation may delay disease onset by about 20 years in people otherwise expected to develop memory loss in their mid-40s.
The mutation affects a protein called reelin, which directs brain cells to break down amyloid plaques and tau tangles, harmful protein build-ups linked to Alzheimer’s.
New research suggests the mutation makes reelin work much more efficiently.
The discovery follows decades of work in the valleys near Medellin, Colombia, where thousands of people carry a rare inherited form of Alzheimer’s caused by a mutation in the presenilin 1, or PSEN1, gene.
Anyone carrying even one copy of the altered gene would be expected to lose their memory in their mid-40s.
The late neurologist Francisco Lopera, who grew up in the region, spent years mapping the affected population.
A year before his death in 2024, he co-authored a paper on a patient who carried the PSEN1 mutation but lived well into his 60s before developing Alzheimer’s.
Lopera found that the man’s brain was protected by another mutation, dubbed COLBOS after the research centres in Colombia and Boston that characterised it.
Research published in December 2025 by molecular biologist Chunyu Wang and colleagues at Rensselaer Polytechnic Institute in New York has now shown how COLBOS works.
The mutation alters how reelin binds to a sugar molecule called heparan sulfate on the surface of brain cells, strengthening that bond and helping reelin build up where its protective signalling is most effective.
There, reelin can help slow key disease processes, including phosphorylation of tau, a chemical change that destabilises the protein and causes toxic tangles to build up in neurons, the brain’s nerve cells.
Joachim Herz, a neuroscientist at the University of Texas Southwestern Medical Center who was not involved in the research, said: “I would never have expected that it would be so protective that it actually negates the effect of a dominant early onset Alzheimer’s disease mutation.
“That I would never have in my wildest dreams predicted.”
Herz, who mapped much of the reelin pathway 20 years ago in mice, believes the COLBOS mutation may make the process of feeding harmful proteins into cell structures that break them down more effective.
However, as the brain ages, defects in those structures may become harder to overcome despite reelin’s effects, meaning the mutation may delay Alzheimer’s rather than prevent it.
The findings could still have implications for future therapies for the far larger number of patients who do not carry high-risk PSEN1 mutations.
Wang pointed to recent research showing that reelin-producing neurons are among the first to die in Alzheimer’s, and suggested that making reelin work more efficiently at brain cell surfaces, even when less of it is present, could protect people from further symptoms.
He is now discussing the development of a gene therapy to enhance reelin signalling based on the findings.
Wang said that even delaying Alzheimer’s by a fraction of the two decades linked to the COLBOS mutation would be a major advance.
Current drugs on the market may extend independent living by two to three years at most, he said, so “20 years is amazing.”
Super-ageing key, Seaweed’s special, hair-raising breakthrough and more
The secret of how ‘super-agers’ have the mental agility of people decades younger is centred around brain health, say US researchers.
Some elderly people are able to regenerate brain cells twice as quickly as other, healthy adults, of the same age.
While it has recently been established that we continue creating brain cells throughout our lives, the new research suggests that some people age without any signs of cognitive decline because their bodies are much better at renewing brain cells.
This is known as neurogenesis and happens in the hippocampus – which is crucial for memory.
“Super agers had twice the neurogenesis of the other healthy older adults,” said Professor Orly Lazarov, of the University of Illinois at Chicago.
“Something in their brains enables them to maintain a superior memory. I believe hippocampal neurogenesis is the secret ingredient, and the data support that.
Amino acid alert
“This is a big step forward in understanding how the human brain processes cognition, forms memories and ages.”
A super-ager is someone aged 80 or older who exhibits cognitive function that is comparable to an average person who is middle-aged.
A study of more than 270,000 participants from the UK Biobank has uncovered a link between a common amino acid and how long men live.
Researchers found that higher levels of tyrosine – an amino acid found in protein-rich foods and often marketed as a focus-boosting supplement – were associated with shorter life expectancy in men.
The study published in Aging-US, from the University of Hong Kong and the University of Georgia, examined the role of phenylalanine and tyrosine in longevity.
Their findings suggest that higher tyrosine levels are associated with shorter life expectancy in men, raising the possibility that longevity strategies may need to differ by sex.
‘Seaing’ into the future
Researchers are using a unique Australian seaweed that mimics the biological functions of human skin to develop sustainable, regenerative wound-healing, anti-ageing solutions for complex skin injuries and burns.
The healing power of seaweed is not a new discovery.
There is evidence that it was chewed medicinally in what is now Chile more than 14,000 years ago, and that seaweed has been a versatile resource for Indigenous Australians for millennia.
It is now believed there are some 12,000 species of seaweed around the world, and that current scientific understanding of the possible benefits of those species is just scratching the surface.
Over the last decade, University of Wollongong researchers at the Intelligent Polymer Research Institute (IPRI) have been investigating a unique Australian green seaweed with antibacterial, anti-inflammatory and regenerative properties.
The team believes this discovery could revolutionise complex wound healing and boost longevity.
Link between obesity and muscle loss
Researchers at the UK’s University of Birmingham have identified a new mechanism by which obesity may contribute to muscle loss in older adults.
The study, published in the Journal of Cachexia, Sarcopenia and Muscle and delivered through the National Institute for Health and Care Research (NIHR) Birmingham Biomedical Research Centre (BRC) shows for the first time that extracellular vesicles – tiny particles released by fat tissue – can directly trigger muscle atrophy in human cells.
Sarcopenic obesity, where excess body fat coexists with reduced muscle mass and strength, is an increasingly common condition in ageing populations and is associated with frailty, reduced mobility, and poorer overall health outcomes.
It is estimated to affect around 11 per cent of the population.
In the study, researchers found that extracellular vesicles released from obese adipose tissue caused significant thinning of muscle fibres derived from older adults, whilst researchers found
that muscle cells derived from younger adults were resilient to these effects.
Lead researcher Dr Joshua Price, first author and Postdoctoral Researcher, said: “It isn’t just having more fat tissue that matters.
“Obesity changes how fat tissue behaves and how it communicates with muscle.
“Ageing muscle is far more vulnerable to these altered signals, which helps explain why muscle loss accelerates with obesity later in life.”
Hair-raising breakthrough
Japanese regenerative health firm OrganTech has pinpointed the trio of cells required to prevent hair loss.
The Tokyo-based biotech said its researchers have defined a three-cell configuration capable of reconstructing hair follicle organ germs to sustain a hair growth cycle.
The work, published in Biochemical and Biophysical Research Communications, provides a potential blueprint for regeneration of hair follicles; which are complex, mini-organs that repeatedly manifest through growth, regression, rest and shedding cycles.
Previous regenerative approaches have combined epithelial stem cells and dermal papilla cells to form early follicular structures.
But, working with researchers at the RIKEN Center for Biosystems Dynamics Research, OrganTech identified a third, previously uncharacterised, cell type that appears to be essential for complete regeneration.
This mesenchymal cell was shown to play a critical role in triggering the transition from the resting to the growth phase of the hair cycle and in driving the follicle’s downward extension into surrounding tissue.
OrganTech CEO Yoshio Shimo, said: “This work defines a foundational cellular configuration for functional hair follicle regeneration.
“Beyond hair biology, it reinforces our broader strategy of organ-level regenerative medicine, where precisely orchestrated epithelial and mesenchymal interactions enable stable and functional tissue reconstruction.”
Low-dose lithium may slow verbal memory decline linked to Alzheimer’s disease in older adults, according to a pilot clinical trial.
The two-year trial enrolled adults aged 60 and older with mild cognitive impairment, a condition where people develop noticeable memory or thinking problems beyond what is typical for their age.
Participants were randomly assigned to receive either a low dose of lithium, a drug long used to treat bipolar disorder, or a placebo.
Over the study period, those receiving lithium showed a slower decline on a sensitive test of verbal memory, the ability to remember and recall words and sentences, which often worsens early in Alzheimer’s disease.
The research was led by Dr Ariel Gildengers, professor of psychiatry at the University of Pittsburgh and a geriatric psychiatrist whose previous work has suggested long-term lithium use in older adults with bipolar disorder is linked with better brain integrity.
“In a prior study, we observed that older adults with bipolar disorder who take lithium long-term tend to show markers of better brain integrity,” Gildengers said.
“The new question was whether those apparent neuroprotective effects might extend beyond mood disorders, and whether we could test that rigorously in a prospective clinical trial.”
Brain imaging showed that the hippocampus, a region of the brain important for memory, shrank over time in both groups.
Although the overall difference between groups did not reach statistical significance, further analysis suggested stronger protective effects among participants who tested positive for amyloid beta, a protein widely considered one of the key biological indicators of Alzheimer’s disease.
The study also found that low-dose lithium was safe and well tolerated in older adults when carefully monitored.
“The key point is that lithium doesn’t restore lost memory,” Gildengers said.
“What it appears to do, if the signal holds up, is slow deterioration. That distinction matters enormously when you’re designing trials and interpreting results.”
However, the trial had limitations. When it began nearly a decade ago, blood-based tests for Alzheimer’s disease were not yet available, meaning participants were enrolled based on clinical symptoms alone.
Only a subset were later found to have amyloid, which may have reduced the study’s ability to detect stronger effects.
“If we were designing this study today, we would enrol participants based on amyloid status from the start,” Gildengers said.
“That’s exactly what we’re planning for next.”
The research team is now seeking support for a larger trial that would use blood-based biomarkers, measurable biological indicators in the blood, to identify individuals most likely to benefit.
“This study tells us that the approach is feasible, safe and worth pursuing,” Gildengers said.
“But it also reminds us why careful, adequately powered trials are essential, especially when the stakes are this high.”
