The risk of dementia increases with age.
But everyone can do a lot to protect themselves as well as possible, reports the World Health Organization.
Geneva - According to a study by the World Health Organization (WHO), the number of people with dementia will rise rapidly.
By 2030, around 40 percent more people worldwide are likely to be living with dementia than today
.
According to estimates, around 55 million people worldwide were affected in 2019, as the WHO reported in Geneva on Wednesday.
According to the Federal Ministry of Health, around 1.6 million people live with dementia in Germany.
A healthier lifestyle prevents dementia
The positive message: Many people could significantly reduce their risk of developing dementia, for example through a healthier lifestyle, good schooling and intact social contacts.
"School education builds brain reserves," said WHO expert Katrin Seeher in Geneva.
She named obesity, high blood pressure *, diabetes, depression and social isolation as risk factors for dementia
.
According to WHO information, smoking and drinking alcohol are also included.
Protection of the brain, such as wearing helmets for certain activities, also reduces the risk of dementia, said Seeher.
One of the main reasons for the rising numbers is the fact that people are getting significantly older than previous generations thanks to better living conditions.
The risk of developing non-communicable diseases, including dementia, generally increases with age
.
"Dementia robs millions of people of memory, independence and dignity, but it also robs us of the people we know and love," said WHO Director General Tedros Adhanom Ghebreyesus.
Cognitive and social skills are lost in dementia
Dementia is usually a progressive disease in the course of which those affected lose cognitive abilities, for example in memory, orientation and language, understanding, learning, planning and assessing. Emotional and social skills can also slowly be lost. This happens more often with advancing age,
but illness or injury can also trigger changes in the brain and thus dementia, including strokes, accidents or Alzheimer's disease.
Most countries are not adequately prepared for the growing number of people with dementia, according to the WHO.
"
The world is failing people with dementia,
" said Tedros.
More must be done to support those affected in a dignified life and not to leave carers alone.
“People with dementia and their families and carers experience discrimination based on age, stigma and social exclusion.
There must be no place for that in our societies, ”said the WHO.
WHO praises German strategy
The WHO presents the national dementia strategy developed in Germany since 2019 as a good example.
It is intended to ensure that people with dementia stay “in the middle of society”, as it says in it. She also praises the regional Alzheimer's societies for their commitment during the corona pandemic. They would have created information material, podcasts and videos to support people with dementia and their caregivers during the time.
The
WHO writes that
interest in research into drugs against dementia has declined after many disappointing clinical studies
.
However, the United States, for example, has increased its annual investment in Alzheimer's research from 631 million dollars in 2015 to 2.8 billion dollars (around 2.4 billion euros) in 2020.
