Alzheimer’s disease Nearly a million people in France are worried. It particularly affects the elderly: it is very rare before the age of 65 and affects about 15% of people over 80. Alzheimer’s disease is a neurodegenerative disease. Nerve cells gradually degenerate resulting in a number of progressive onset symptoms. The most well-known symptom of the disease is memory loss. But it is not the only one: patients also have disorders of executive functions and orientation in time and space. today this disease cannot be neither did well nor warned, The knowledge of the first signs of Alzheimer’s disease is very complex. When a patient is diagnosed, the disease is very often already advanced at this stage.

a study of 80,000 people

A French team has published the results of a study involving 80,000 patients in the prestigious journal the Lancet, Half of them developed Alzheimer’s disease while the other half formed a control group and never developed a neurodegenerative disease during the study period.

The authors tested the link between disease onset and 123 health factors through statistical analysis. The results show an association between the list of 10 pathologies and the occurrence of Alzheimer’s disease within 15 years. Depression is the first of these pathologies, followed by anxiety, exposure to Tension Vital, hearing loss, constipation, cervical spondylarthrosis, memory loss, fatigue, falls and sudden weight loss. Some of these pathologies were already known to predispose patients to the development of Alzheimer’s disease, such as depression or hearing loss. Others rarely, such as cervical spondylarthrosis or constipation.

Statistical link only

The authors point out that their study only sheds light on statistical links, which do not constitute evidence of cause and effect. A thorough study of the underlying mechanism is necessary.

Furthermore, it is not possible to know from the article cited here whether suffering from depression leads to Alzheimer’s disease or whether depression is an early symptom of the disease. Nevertheless, this type of information is very useful for better understanding the disease and trying to prevent it.

Soon, the authors extended their analysis to a large number of cases (26 million!) and other degenerative pathologies such as Parkinson’s diseaseThe Charcot disease or multiple sclerosis,
