Alzheimer’s is a very current disease in our society and unfortunately, there is currently no cure for it. It is a neurodegenerative disease that appears as a result of the progressive loss of neurons and prevents the nervous system from functioning properly. When this happens, the patient experiences amnesia and disorientation in their daily life.

This process progresses rapidly and the person who is suffering from it becomes completely dependent. It is the most common type of dementia in older people, accounting for seven out of ten cases of people with dementia. About 700,000 people in Spain, 100,000 in Catalonia and 50 million in the world suffer from dementia.

These figures have been increasing in recent years due to the increase in life expectancy in the world and this trend will continue in the coming decades as well. The World Health Organization (WHO) estimates indicate that in the year 2050 there will be more than 150 million people suffering from this disease in the world. The frequency of new cases is very high: a new case is diagnosed every three seconds and ten million new patients are recorded every year. In economic terms, the costs associated with Alzheimer’s and other dementias are as high as 1% of world GDP.

On 21 September, World Alzheimer’s Day was observed, declared by WHO and sponsored by Alzheimer’s Disease International (ADI). This organization advocated and achieved that World Day would not be limited and that September would be declared as World Alzheimer’s Month. Above all, it is about raising awareness of this disease, which not only affects patients but also directly caregivers and family members.

Drug treatment relieves and improves symptoms of the neurodegenerative process, but it does not cure or stop it. Scientific progress has been made in recent years, but so far without achieving the challenge of finding a solution to this disease. Meanwhile, there are habits that improve the quality of life of Alzheimer’s patients: neuropsychological therapy based on moderate physical activity, a balanced diet and stimulating the patient’s mental abilities (memory, language, imagination …).
