We all surely know some of the most common benefits of laughter, but a recent study by researchers from Loma Linda University in California, US, has revealed that much more than offering relief through humour, laughter is a vital tool to the health for our physical and mental state.
The study was carried out among 20 healthy adults between the ages of 60 and 70, in which the levels of stress and short-term memory were assessed. The research was divided into two groups: the first group was asked to sit quietly, read or use their mobile phones without speaking; while the second group was shown funny videos.
After 20 minutes, the participants from both groups gave saliva samples and also underwent tests of short-term memory.
The results showed that the group of people who had been exposed to comedy videos scored significantly better on tests of short-term memory than the other study group. The so-called "group of humour" improved their memory by 43.6% in comparison to the results gained in the pre-study test. The other group improved as well, but with not as much success, bettering their previous score by 20.3%
On the other hand, the group of individuals who sat through 20 minutes of funny videos showed considerably Read more
Alzheimer’s is a form of dementia that affects the functionality of the brain causing memory problems, difficulties when developing thought processes and problems in our behaviour.
One of the aspects that without a doubt makes the disease more serious is the worsening of symptoms over time, which greatly decreases the quality of life of patients.
Fortunately, after years of study of the disease, the medical community has come to the conclusion that there are certain risk factors which, if reduced, could prevent millions of people being affected by Alzheimer's.
There are seven determining risk factors
When physicians refer to variables that can negatively impact the development of Alzheimer's, they indicate the following main factors:
High blood pressure
Low mental activity
It is important to highlight that Alzheimer's is not part of the human being's own process of ageing. Clearly, there is an increased likelihood of developing this disease in the following patients:
Alzheimer’s disease is definitely one of the illnesses of our time and also probably of our future, as well as being one of the most common causes of dementia.
This degenerative disease usually manifests itself through increasingly frequent forgetfulness or carelessness. However, we must remember that, in addition to our memory, it may affect the patient’s ability to communicate (language), their reasoning, their behavior and their ability to understand.
Fortunately, in the last few years significant progress has been made towards the discovery of a vaccine against Alzheimer's disease that will minimize the impact of the disease on patients, as well as improve their quality of life at all levels.
Figures that we should not eliminate from our memory
Taking stock of the current situation of the disease in our environment, we can review the numbers of affected people in countries such as Spain, where the figures reach 500,000 patients and where it is estimated that there could also be about 300,000 cases yet to be diagnosed.
With regard to research into Read more
