A disease unfortunately unique. Researchers found that increasing symptoms of anxiety were linked to higher levels of beta-amyloid, which is a protein associated with Alzheimer’s disease, in the brains of older people with normal cognitive functioning.

First study author Dr. Nancy Donovan, who is a geriatric psychiatrist at Brigham and Women’s Hospital in Boston, MA, and team say that the results suggest that a rise in the sypmtoms of anxiety could be an early sign of Alzheimer’s.

Alzheimer’s disease is a form of dementia characterized by problems with memory and thinking, as well as changes in behavior.

It is estimated that around 5.5 million people in the U.S. are living with Alzheimer’s, of whom around 5.4 million are over the age of 65.

The precise causes of Alzheimer’s disease remain unclear, but scientists believe that beta-amyloid plays a key role. This is a protein that can form “plaques,” which have been found to block nerve cell communication in the brains of people with Alzheimer’s.

These plaques are considered to be a hallmark of the disease, and researchTrusted Source has suggested that an increase in beta-amyloid levels can occur up to 10 years before the onset of Alzheimer’s symptoms.

According to the new study, anxiety could play a significant role in increased beta-amyloid levels among older adults.

Symptoms of anxiety and depression among the adults were assessed using the 30-item Geriatric Depression Scale.

It was found that adults who showed an increase in anxiety symptoms over 5 years of follow-up also had higher levels of beta-amyloid in their brains. The researchers say that this indicates that worsening anxiety might be an early sign of Alzheimer’s disease.

The researchers concluded that hospital-treated infections are linked to an increased risk of AD and PD diagnosis before age 60, although underlying mechanisms remain unknown.

When asked about the study’s limitations, Dr. Sun noted that they did not have complete information on all risk or protective factors for neurodegenerative conditions, including lifestyle factors, medical factors such as trauma or vascular-related brain damage, and genetic factors.

Charlotte Warren-Gash, Ph.D., an associate professor at the Faculty of Epidemiology and Population Health at the London School of Hygiene and Tropical Medicine, not involved in the study, also told MNT:

“The study covered a long period of time, from 1970 [to] 2016, during which diagnostic criteria and clinical practices have undergone major changes. How applicable results are to patients with infections today remains unclear.”

Dr. Doig added: “The people studied were all Swedish with both parents also born in Sweden, so the results may not generalize outside this group.”

Dr. Strandberg noted that a key message should be that “infections should be carefully treated — as they should anyway — with a low threshold for cognitive testing as needed.”

  • Researchers from Boston University have found that applying noninvasive electrical stimulation to certain parts of the brain may help improve long-term and working memory in people over the age of 65 for up to a month.
  • Scientists hope their findings will help with other medical conditions, including Alzheimer’s disease, schizophrenia, and anxiety.

Memory loss can be part of the aging process. Researchers estimate that about 40%Trusted Source of people ages 65 and older experience memory loss.

While medicationsTrusted Source and other treatment options can help with memory loss due to aging, there is currently no cure for the condition.

Memories are housed in certain areas of the brain and fall into three different categoriesTrusted Source: long-term, short-term, and working memory.

Long-term memoryTrusted Source helps a person recall the skills they need to perform their job or a special event that happened many years ago. The hippocampusTrusted Source area of the brain stores long-term memories.

The brain stores short-term memoriesTrusted Source for a very short amount of time — only about 30 secondsTrusted Source — and these are stored in the prefrontal cortexTrusted Source. Examples of short-term memories are where you parked your car at the mall or what you ate for breakfast this morning.

Working memory is usually considered synonymous with short-term memory. However, past researchTrusted Source shows that working memories last a bit longer than short-term memories and help with completing cognitive tasks.

“That is, the electrical stimulation is taking control of the timing of brain activities,” he said.

“Time is a crucial variable in the brain. The brain is constantly sending and receiving packets of information at blinding fast speeds. Brain rhythms are an exquisite solution that the brain has evolved to use to efficiently coordinate these fasting-moving bundles of information which make up our memories,” pointed out Dr. Reinhart.PicnicHealth allows you to organize up to 7+ years of medical records through a HIPAA compliant, routinely-updated digital timeline under your control.

  1. Forgetfulness, especially in older people, is the chief contributing factor that negatively affects their overall quality of life, necessitating constant help and support from their family members….
    May the researchers on the subject rededicate their efforts this World Alzheimer’s Day for a solution to this nagging issue confronting the society!
