A new American study warns that anxiety may be one of the first signs of Alzheimer’s.
The psychological condition can help to detect Alzheimer’s disease early – thus allowing medical intervention and early treatment, reducing the effects of the degenerative condition.
The new study, conducted by researchers at Brigham and Women’s Hospital in Boston, United States, may have found a direct relationship between high levels of anxiety and the onset of Alzheimer’s in older people.
So far, previous research has pointed out major depression and other neuropsychiatric symptoms as possible early signs of Alzheimer’s in its pre-clinical phase, when there is a greater accumulation of beta-amyloid protein in the brain of those affected.
Scientists estimate that this stage of the disease may occur up to a decade before the effects of dementia begin to appear.
In this sense, the researchers decided to examine the association between the appearance of beta amyloids and measures of depressive symptoms in 270 male and female patients, between 62 and 90 years old, without psychiatric disorders.
As such, they realized that higher levels of peptides may be associated with increasing symptoms of anxiety. In other words: anxiety can be an early sign of Alzheimer’s.
