In France, 900,000 people suffer from Alzheimer’s disease, a neurodegenerative pathology which is rather feminine (it reaches 15 women for 10 men) and which remains rare before the age of 65.
Several factors favoring the development of Alzheimer’s disease have already been identified: these include physical inactivity, cranial microtrauma, untreated chronic diseases (arterial hypertension, diabetes, etc.) or even repeated anesthesia.
A new study, conducted by Florida State University (in the United States), may have just brought to light an additional risk factor for Alzheimer’s disease: according to American researchers, people who experience changes Frequent emotional attacks would have an increased risk of developing this pathology.
Certain personalities have an increased risk of developing Alzheimer’s disease
To reach this conclusion, the scientists carried out two studies in parallel. During the first, a group of volunteers completed a (long) personality questionnaire; a year later, the participants underwent a PET scan to observe the presence of signs of Alzheimer’s disease. In the second, the researchers reviewed 12 previous studies concerning the links between Alzheimer’s disease and certain personality traits.
Verdict: According to scientists, people who frequently undergo emotional changes, who suffer from anxiety and/or who have already been diagnosed with depression have an increased risk of developing Alzheimer’s disease. Conversely, a cautious, detail-oriented and goal-oriented personality would be less at risk. Good to know…
