Who was the study carried out on?
The research was carried out over a period of three years. 376 adults, aged 55-91 were analysed for anxiety, depression, cognitive and brain structural changes. Changes in patients were monitored every 6 months. All of the adults had a clinical diagnosis of MCI and a low score on the depression rating scale, indicating that anxiety symptoms were not part of clinical depression
What should one watch out for?
People with anxiety issues and those suffering from MCI should get themselves monitored regularly for any deteriorating signs. Anxiety in patients with MCI is a signal that these patients are at a greater risk of developing Alzheimer s. The study concludes that anxiety can predict if MCI may develop into Alzheimer s.
