The World Health Organization defined dementia as a syndrome in which there is deterioration in memory, thinking, behaviour and ability to perform everyday activities. It is not a normal part of ageing.
There are mainly four types of dementia. The first and the most common type is 'Alzheimer's dementia, which generally starts after the age of 60. The symptoms of this kind of dementia are memory loss, sleeplessness, and change in personality which eventually hampers the regular work process of a person in the long run.
The second type is vascular dementia and people who are obese and follow a sedentary lifestyle or have health issues like heart diseases are more prone to this type of dementia. Lifestyle modification plays a very important role in keeping away from vascular dementia.
The other two categories of dementia are Frontotemporal dementia and Lewy Body dementia. Research conducted at the University of Washington School of Medicine concluded that the number of dementia cases might triple to more than 152 million by 2050.
There are mainly four types of dementia. The first and the most common type is Alzheimer's dementia, which generally starts after the age of 60.This conclusion was drawn based on anticipated trends in smoking, high body mass index and high blood pressure. They found an increase of 6.8 million dementia cases globally between 2019 and 2050 due to expected changes in these risk factors.
During the research, it was found that expected changes in educational levels will lead to a decline in dementia prevalence of 6.2 million individuals globally between 2019 and 2050.
After reviewing data which was presented at the Alzheimer's Association International Conference held in Denver in 2021, the Alzheimer's Association chief science officer Maria C. Carrillo said that in developing countries, lifestyle modification among adults including access to education and attention to heart health has reduced the number of young Alzheimer's patients in the recent years but it has been the opposite in the cases of persons who are growing older with age.
Another research on dementia showed that every year, 10 out of 1, 00,000 people develop dementia with early-onset, prior to the age of 65, which corresponds to around 350,000 new cases every year. Middle East, North Sub-Saharan Africa, North Africa has the maximum cases of this syndrome. Apart from medicines and therapies, lifestyle modification is the basic step to correct and prevent dementia.
