Dizziness in older adults is linked to higher risk of future falls
Researchers say it’s not just a normal part of ageing
The first meta-analysis of its kind has shown a conclusive link between older adults experiencing spells of dizziness and a dramatically elevated risk of falling.
Dizziness is a term used to describe sensations such as vertigo, imbalance, light-headedness, and disorientation. It is common in older adults, affecting one in three of those aged 65 years and older. For the first time, dizziness has been confirmed as an independent predicting factor for falls.
Researchers at Imperial assessed the link by systematically reviewing and meta-analysing 29 peer-reviewed research studies, involving a total of 103,000 participants.
They found that older adults who experience dizziness were over 60% more likely to fall in the future, even considering other factors that might have contributed to a risk of a fall. In a further finding, individuals with dizziness had approximately double the likelihood of falling more than once.
Dr Toby Ellmers at the Centre for Vestibular Neurology, Department of Brain Sciences at Imperial College London, senior author on the study said: “Our study conclusively shows that older people with dizziness are at high risk of experiencing falls.”
Falls are the most common cause of death from injury in the over 65s. The National Institute for Health and Care Excellence (NICE), which provides guidance and advice on health, estimates that falls cost the NHS £2.3 billion per year and over 4 million bed days. Hip fractures from falls affect mobility and quality of life, and can lead to increased institutionalisation and mortality.
Although dizziness is common, the researchers say it is caused by specific and distinct diagnoses with specific treatments and even cures. They stress that dizziness shouldn’t be viewed as a ‘normal’ part of ageing.
The most common causes of dizziness in older people include: Benign Positional Vertigo, where crystals in the inner ear’s balance system become dislodged; orthostatic hypotension, due to blood pressure falling on standing; and a form of migraine called vestibular migraine.
Dr Ellmers noted that dizziness is the commonest reason for patients to be referred to his Imperial colleague’s general neurology clinics, highlighting that awareness of the problem was important amongst clinicians.
Dr Ellmers said: “Older adults with even non-bothersome dizzy spells should make an appointment with their GP, to enable early diagnosis and treatment to prevent falling. That will help to avoid a hospital admission or worse.”
This work was supported by a Wellcome Trust Sir Henry Wellcome Postdoctoral Fellowship awarded to Toby J. Ellmers (Grant Number: 222747/Z/21/Z), and by a Lee Family Scholarship awarded to first author, PhD student Yuxiao Li.
Association between dizziness and future falls and fall-related injuries in older adults: a systematic review and meta-analysis is published in Age and Ageing.

Triptans more effective than newer, more expensive migraine drugs
2024-09-18
Some triptans are a more effective treatment for acute migraines than newer, more expensive drugs, finds an analysis of the latest evidence published by The BMJ today.
Triptans work by narrowing blood vessels in the brain and preventing the release of chemicals that cause pain and inflammation.
The findings show that four triptans - eletriptan, rizatriptan, sumatriptan, and zolmitriptan - were better at relieving migraine pain than the recently marketed and more expensive drugs lasmiditan, rimegepant, and ubrogepant, which were comparable to paracetamol ...
Iron given through the vein corrects iron deficiency anaemia in pregnant women faster and better than iron taken by mouth
2024-09-18
Researchers found that a medicine called ferric carboxymaltose given in drip through the vein works faster and better than an iron tablet taken by mouth for the treatment of anaemia – and it is as safe as the tablet. The findings were published in Lancet Global Health.
Anaemia (low blood level) is a common cause of ill-health or death in mothers and their babies, especially in sub-Saharan Africa and South-East Asia where more than four out of ten pregnant women have the condition. A sizeable proportion of pregnant women in Nigeria proceed to giving birth while still anaemic ...
The Lancet Neurology: Air pollution, high temperatures, and metabolic risk factors driving global increases in stroke, with latest figures estimating 12 million cases and over 7 million deaths from st
2024-09-18
Between 1990 and 2021, the number of people who had a new stroke (up by 70%), died from a stroke (up by 44%), and stroke-related health loss (up by 32%), has risen substantially worldwide.
Stroke is highly preventable, with 84% of the stroke burden in 2021 attributable to 23 modifiable risk factors, including air pollution, excess body weight, high blood pressure, smoking, and physical inactivity—presenting a public health challenge and an opportunity for action.
Notably, the contribution of high temperatures to poor health and early death due to stroke has ...
Incidence of neuroleptic malignant syndrome during antipsychotic treatment in children and youth
2024-09-18
A new study in the peer-reviewed Journal of Child and Adolescent Psychopharmacology estimated the incidence of neuroleptic malignant syndrome (NMS), a potentially fatal adverse effect of antipsychotic treatment, among individuals ages 5-24 years. Click here to read the article now.
Wayne Ray, PhD, from the Vanderbilt University School of Medicine, and coauthors, used national Medicaid data from 2004-2013 to identify patients beginning antipsychotic treatment and calculated the incidence of NMS during antipsychotic use. The investigators identified five ...
Levels of protection from different cycle helmets revealed by new ratings
2024-09-18
Cyclists choosing a new helmet can see how much protection different helmets offer, thanks to new safety testing and ratings from Imperial College London.
Researchers at Imperial College London have developed a simple new cycle helmet safety rating system with simple-to-understand scores from 0-5, designed to help buyers select which helmet to buy and assist manufacturers in future helmet design. The system is based on extensive new safety testing experiments on medium-sized helmets at Imperial.
Testing on the UK’s 30 most popular helmets, funded by The Road Safety Trust, revealed significant ...
Pupils with SEND continue to fall behind their peers
2024-09-18
Pupils with special educational needs and disabilities (SEND) are continuing to fall behind their peers with the gap widening despite the introduction of SEND legislation.
This is according to a new study by Durham University which analysed data on 2.5 million Year 6 pupils across four school years from 2014-2019.
The research suggests there is a need to re-evaluate the policies for SEND provision and how pupils with SEND are supported in schools.
It calls for more investment to support SEND pupils and for increased professional development for teachers and teaching assistants.

Half of heavier drinkers say calorie labels on alcohol would lead to a change in their drinking habits
Just over half of heavier drinkers in England say they would make changes to their drinking if calorie labels for alcohol were introduced, according to a new study by UCL researchers.
The findings, the researchers said, suggested calorie labels could help some drinkers maintain a healthier weight.
The study, published in the journal BMJ Open, looked at survey responses from 4,683 adults in England to assess the impact that alcohol calorie labelling might have on people’s attitudes and drinking ...
Study first to link operating room design to shorter surgery

New study uncovers therapeutic inertia in the treatment of women with multiple sclerosis
2024-09-18
A study has revealed significant therapeutic inertia in the treatment of women with multiple sclerosis (MS), highlighting gender disparities that could impact long-term health outcomes for women of childbearing age.1
The findings, presented today at ECTRIMS 2024, suggest that concerns related to pregnancy may lead to delayed or reduced use of disease-modifying treatments (DMTs), even before pregnancy becomes a consideration.
In an extensive analysis of 22,657 patients with relapsing MS (74.2% women) who were on the French ...
