About 78 million people may have dementia by 2030, the World Health Organization (WHO) estimates in a new report - a 42% increase from 2019. By 2050, that number could be 139 million.It would be a 42 percent increase from current figures - the number was 55 million in 2019.
is an overall term for a range of specific conditions caused by abnormal brain changes. These brain abnormalities trigger a decline in thinking skills which can have an impact on your behaviour, feelings and relationships.

There are several different causes of dementia -being the most common cause.
There are several established warning signs of dementia, but a new study has identified a new potential signifier for this disease,
The inability to detect speech in a noisy environment is a hallmark of hearing impairment and Oxford researchers now believe it is linked to dementia.
In a study of 82,000, 1,285 people developed dementia and researchers found people who struggled to hear conversation in raucous environments were more likely to get the disease.
The study followed people aged over 60 for 11 years.
Lead author Dr Jonathan Stevenson said: "Difficulty hearing speech in background noise is one of the most common problems for people with age-related hearing impairment.
Traffic and railway noise associated with dementia, study suggests
The Danish study found that over an average of 8.5 years some 31,219 participants received a diagnosis of Alzheimer's disease and 8,664 a diagnosis of vascular dementia.Researchers in Denmark monitored almost two million adults aged 60 or older living in the country between 2004 and 2017.
"This is the first study to investigate its association with dementia in a large population."
People who struggled to hear in loud environments were almost twice as likely to get dementia as those who had no difficulty hearing friends at a bar,
Even people who performed better, but were still "insufficient", were at 61 percent higher risk.
The study did not conclude if hearing issues cause dementia or if they are merely a symptom - and experts are split on this as well.
Anyone struggling with hearing issues is advised to speak medical advice as it could be a precursor to dementia.
What are the warning signs of dementia?
Some common symptoms which may appear before a diagnosis of dementia include:
- Memory loss
- Difficulty concentrating
- Finding it hard to carry out familiar daily tasks, such as getting confused over the correct change when shopping
- Struggling to follow a conversation or find the right word
- Being confused about time and place
- Mood changes.
- Often these symptoms may be mild and worsen gradually over time.
Alzheimer's disease patients may also develop difficulty regarding numbers or handling money.
In addition, they may ask questions repetitively or become more withdrawn or anxious.
Vascular dementia is the second most common cause of dementia and with these conditions, symptoms can sometimes develop suddenly and worsen quickly.
Precursor symptoms to a diagnosis of vascular dementia may include stroke-like symptoms such as muscle weakness or temporary paralysis, and movement problems.
Furthermore, people may have thinking problems and mood changes.
