data from a national study on child development, which began in 1958. It was attended by 18 558 people. Scientists have followed their development throughout their lives. At the age of 7 to 50, participants were periodically tested for depression and anxiety.
As a result, psychologists from Sussex found that one episode of depression or anxiety had little effect on memory functions in adults.
But when the episodes increased to two or three during the first 30 years of life, this predicted a decrease in memory function by the time the participant reached 50 years old.
In addition to memory, psychologists also evaluated cognitive functions such as fluency and speech processing speed. Episodes of depression and anxiety had little effect on these functions.
"We found that the more episodes of depression that people experience in adulthood, the higher the risk of cognitive impairment in their later life. This conclusion emphasizes the importance of treating depression effectively to prevent the development of long-term mental health problems, "- summarized the findings of the study, senior lecturer at the University of Sussex Daria Gasina.
Depression is one of the most common mental disorders. The World Health Organization estimates that more than three hundred million people worldwide experience depression. Depression can negatively affect health, for example, causing chronic pain, heart disease, diseases of the gastrointestinal tract and other serious consequences.
