What is Mixed Dementia?

Mixed dementia is the condition in which two forms of dementia coexist.

An Alzheimer’s Association research study into mixed dementia describes it as a condition in which a person has more than one type of dementia. Alzheimer’s disease and vascular dementia is the most common type’.

Due to our ageing population, the number of people with dementia in the UK is continuing to increase. Although Dementia mainly affects people over the age of 65, it can also affect those under this age.

Types of Mixed Dementia

Vascular Dementia and Alzheimer’s Disease

As indicated, one of the most common forms of mixed dementia is when a person is diagnosed with both Vascular dementia and Alzheimer’s disease. Although far less common, other combinations are also possible, such as Alzheimer’s disease and Lewy bodies.

Alzheimer’s disease is where a build-up of proteins forms blockages and tangles, which in turn can cause nerve cells to die and brain tissue to be lost. This causes chemical messages to be interrupted, affecting a person’s cognitive abilities.

Vascular dementia relates to reduced blood flow around the brain. If blood vessels are damaged due to strokes, mini-strokes, or gradual deterioration, this can mean that the blood flow providing oxygen and nutrients to the brain is affected.

Lewy Bodies and Alzheimer’s Disease

The less common form of mixed dementia is the combination of Alzheimer’s disease and Lewy bodies.

Lewy bodies are protein deposits that form in the brain and can affect a person’s movement. Those affected with Lewy body disease may experience disturbed sleep, hallucinations, confusion, disorientation, and sudden changes in the ability to function without help.

Symptoms Of Mixed Dementia

The symptoms of dementia can cause a decline in a person’s cognitive abilities, such as:

– Processing information
– Decision making
– Having Difficulty with day-to-day tasks
– Fluctuating Moods
– Struggling with communication
– Memory loss
– Confusion

This is not an exhaustive list as the symptoms of mixed dementia may vary depending on the types of dementia that have been diagnosed as well as the areas of the brain that have been affected.
