2 course changes that predict dementia 6 years before onset

Changes in balance and gait may indicate either late-stage Alzheimer's disease or early vascular dementia.

Neurological changes are common in the early stages of cognitive decline, but studies show that physical changes can also be indicative. In fact, the researchers have built a clear picture of the complex relationship between physical function and the onset of dementia.

Their findings show that changes in a person's balance or the way they walk can tell a lot about their cognitive status. Symptoms can vary from person to person with dementia, but sometimes physical changes appear before memory loss.

In one study, people who walked slowly or had poor balance were more likely to be diagnosed with Alzheimer's disease six years later.

These changes indicate that brain cells and nerve communication are slowly wearing out. This deterioration will progress into late-stage dementia, eventually affecting the patient's ability to walk freely or process information about their physical environment.

Problems viewing and processing information about the physical environment can lead to balance problems.

In the early stages or even before other symptoms of dementia develop, loss of balance when standing or walking may indicate an increased risk of Alzheimer's disease. It can also be a good sign that your loved one is suffering from dementia other than Alzheimer's,” explains the neurologist.

Vascular dementia, for example, differs from Alzheimer's because the disease is caused by a lack of blood flow, which delivers oxygen to the cerebellum.

“Some people with vascular dementia actually experience dizziness before they have problems with thinking and memory.”
