The researchers tested the reduction of hippocampal activity and how it would affect human brains with aMCI. The researchers used a low-dose drug commonly used to treat epilepsy, reducing hippocampal activity. The drug treatment improved memory performance and offers insight into a possible new effective therapy for aMCI.
Dr. Gallagher concluded, “Apart from a direct role in memory impairment, there is concern that elevated activity in vulnerable neural networks could be causing additional damage and, possibly, widespread disease-related degeneration that underlies cognitive decline and the conversion to Alzheimer’s disease. Therefore, reducing the elevated activity in the hippocampus may help to restore memory and protect the brain.”
Amnestic mild cognitive impairment may double the risk of death
Previous research has found that amnestic mild cognitive impairment doubles the risk of death. The researchers looked at 733 older adults who were all evaluated at baseline for cognitive ability. They were also tested for the APOE-4 gene variant which is a known factor to increase the risk of Alzheimer’s disease.
The researchers found that those with amnestic mild cognitive impaired had double the risk of death, compared to those who didn’t. On the other hand, non-amnestic mild cognitive impairment did not show to increase the risk of death.
Senior author Richard Lipton said, “While there is no treatment for MCI, dementia, or Alzheimer’s, these findings support the benefits of early detection and monitoring of cognitive impairment in order to prolong life.”
Treatment options for amnestic mild cognitive impairment
Currently, amnestic mild cognitive impairment cannot be reversed or cured, but rather it can be slowed down. A common form of treatment for aMCI is to prescribe common Alzheimer’s drugs, but numerous clinical trials have not shown much benefit from this practice.
Adopting a healthy lifestyle could be beneficial for someone living with aMCI in order to better manage symptoms. Smoking should be stopped and alcohol consumption should be minimized as both can have negative effects on the brain. Exercise, too, has been shown to protect the brain against dementia, along with a healthy diet.
Managing other medical conditions can also be beneficial in managing aMCI, like reducing blood pressure and cholesterol or managing diabetes.
Other tips to help manage aMCI in the elderly:
- Take medications as recommended by your doctor
- Reduce stress and anxiety
- Keep up with a regular daily routine to minimize memory problems
- Use calendars, diaries, memos, and reminders
- Keep your mind active with puzzles or learning something new
- Take time to relax
- Get proper sleep
- Stay social and keep a strong social network
- Visit a memory support group
By following these tips and working closely with your doctor, you can have better success in managing aMCI and slowing your risk of dementia.
