Lewy body dementia occurs when tiny clumps of proteins known as Lewy bodies appear in the nerve cells of the brain. Lewy bodies cause a range of symptoms, some of which are shared by Alzheimer’s disease and some by Parkinson’s disease.
Common signs and symptoms include sleepwalking, seeing things that aren’t there (visual hallucinations), and problems with focus and attention. Other signs include uncoordinated or slow movement, tremors, and rigidity (parkinsonism).
Frontoemporal dementia is a group of diseases characterised by the breakdown of nerve cells and their connections in the frontal and temporal lobes of the brain. These are the areas generally associated with personality, behaviour and language.
Mixed dementia refers to when individuals have more than one type of dementia. The condition affects at least one in 10 people. Depending on the types of dementia a person has, symptoms will slightly differ.
