New Study Shows That Elderly With Symptoms of Depression Are More Prone to Memory Problems

"Since symptoms of depression can be treated, it may be possible that treatment may also reduce thinking and memory problems," said study author Adina Zeki Al Hazzouri of the University of Miami Miller School of Medicine in Florida, US.

Depression may speed up brain ageing and lead to memory problems in older adults, suggests new research that offers hope of finding a new way to treat memory issues.

“Since symptoms of depression can be treated, it may be possible that treatment may also reduce thinking and memory problems,” said study author Adina Zeki Al Hazzouri of the University of Miami Miller School of Medicine in Florida, US.

The study, published in the journal Neurology, also showed that older people with greater symptoms of depression may have structural differences in the brain compared to people without symptoms.

“With as many as 25 per cent of older adults experiencing symptoms of depression, it’s important to better understand the relationship between depression and memory problems,” Zeki Al Hazzouri said.

The study involved over 1,000 people with an average age of 71.

At the beginning of the study, all the participants had brain scans, a psychological exam and assessments for memory and thinking skills. Their memory and thinking skills were tested again an average of five years later.

At the start of the study, 22 per cent of the participants had greater symptoms of depression.

The researchers found that greater symptoms of depression were linked to worse episodic memory — a person’s ability to remember specific experiences and events.

Those with greater symptoms of depression had differences in the brain including smaller brain volume as well as a 55 per cent greater chance of small vascular lesions in the brain, the findings showed.

“Small vascular lesions in the brain are markers of small vessel disease, a condition in which the walls in the small blood vessels are damaged,” said Zeki Al Hazzouri.

“Our research suggests that depression and brain ageing may occur simultaneously, and greater symptoms of depression may affect brain health through small vessel disease,” Zeki Al Hazzouri added. (IANS)

Increased use of digital media may be partly responsible for the growth in the percentage of young adults experiencing certain types of mental health disorders in the US over the past decade, suggests new research.

“More US adolescents and young adults in the late 2010s, versus the mid-2000s, experienced serious psychological distress, major depression or suicidal thoughts, and more attempted suicide,” said lead study author Jean Twenge, Professor of Psychology at San Diego State University in the US.

“These trends are weak or non-existent among adults 26 years and over, suggesting a generational shift in mood disorders instead of an overall increase across all ages,” Twenge added.

For the study, the researchers analysed data from the National Survey on Drug Use and Health, a nationally representative survey that has tracked drug and alcohol use, mental health and other health-related issues in individuals aged 12 and over in the US since 1971.

They looked at survey responses from more than 200,000 adolescents aged 12 to 17 from 2005 to 2017, and almost 400,000 adults aged 18 and over from 2008 to 2017.

The rate of individuals reporting symptoms consistent with major depression in the last 12 months increased 52 per cent in adolescents from 2005 to 2017 – from 8.7 per cent to 13.2 per cent — and 63 per cent in young adults aged 18 to 25 from 2009 to 2017 – from 8.1 per cent to 13.2 per cent, showed the findings published in the Journal of Abnormal Psychology.

“Cultural trends in the last 10 years may have had a larger effect on mood disorders and suicide-related outcomes among younger generations compared with older generations,” said Twenge.

She believes this trend may be partially due to increased use of electronic communication and digital media, which may have changed modes of social interaction enough to affect mood disorders.
