Dementia with Lewy bodies symptoms: This sign in your sleep can indicate the disease

Dementia is classified into four categories: Alzheimer’s, vascular dementia, dementia with Lewy bodies and frontotemporal dementia.

The third most common type, dementia with Lewy bodies (DLB), accounts for 10-25 percent of cases.

There are some specific symptoms associated with the disease, but some of these signs are also seen in Parkinson’s dementia.

According to the Alzheimer’s Association one of the symptoms of dementia wth Lewy bodies appears during sleep.

Acting out dreams, sometimes violently, is a problem known as rapid eye movement (REM) sleep disorder. This can be an indicator.

Other signs of this type of dementia include changes in thinking and reasoning, confusion and alertness that varies significantly from one time of day to another or from one day to the next, and visual hallucinations.

Delusions can also happen, as well as trouble interpreting visual information, malfunctions of the “automatic” (autonomic) nervous system, and memory loss that may be significant but less prominent than in Alzheimer’s.

Parkinson’s symptoms, such as a hunched posture, balance problems and rigid muscle can also appear.

Parkinson’s disease dementia is the diagnosis if a person is originally diagnosed with Parkinson’s, and dementia symptoms don’t appear until a year or more later.

The overlap is thought to be due to abnormalities in how the brain processes the protein alpha-synuclein. “Many people with both DLB and Parkinson’s dementia also have plaques and tangles — hallmark brain changes linked to Alzheimer’s disease,” the organisation states.

While there’s currently no cure for dementia, there are ways you and your family can prevent dementia developing in later life.

One of these is eating well. According to Bupa, following a diet to reduce your risk of dementia will also help to reduce your risk of other diseases, such as heart disease and stroke.

The first diet change it recommends to make is to eat more fruit and vegetables.

You should also make sure to eat more fish, especially oily fish, more wholegrain cereals, and less saturated fat from red meat and dairy products.

Less sugar and processed food and less salt should also form part of your healthy eating plan.

The health organisation adds: “Try to eat at least five portions of fruit and vegetables a day, and at least two portions of fish a week. At least one portion of fish should be oily fish, such as salmon or mackerel.

“Alcohol isn’t generally a risk factor for dementia, although some studies have linked it to vascular dementia.

“But, to stay healthy, it’s still a good idea to stick within the recommended limits of no more than 14 units a week. That works out as around six regular glasses of wine or six pints of beer.”

One of the most important aspects of a healthy diet to prevent dementia is to drink plenty of water.

Six to eight glasses a day is the recommendation by Alzheimer’s Society.

According to Dr Andrew Thornber, Chief Medical Officer at Now Patient, dementia is a terminal illness that shuts down the brain, and sadly it can kill a person
