Other conditions

Alzheimer’s disease

Alzheimer’s disease is the most common dementia type. It is mostly a disease of older age but can present in some people under 65. Memory impairment is normally the most common symptom. Other symptoms include: Loss of ability to plan and do tasks, visual disturbances and behavioural symptoms. 

Parkinson’s disease (PD)

Parkinson’s disease is a neuro-degenerative condition that begins as a movement disorder. The main symptoms are tremor, slowness of movement, stiffness and also postural instability (difficulty staying upright). Over long-term follow-up, up to 80% of patients with PD develop associated cognitive symptoms.

Mixed dementia

Some people have a mixed diagnosis. They have signs of both dementias and therefore are deemed have a dual or a mixed type of dementia. Your doctor may inform you that you have features of both DLB and Alzheimer’s.

Parkinson’s disease dementia

This form of dementia occurs in people who present with motor problems and generally receive a diagnosis of Parkinson’s disease. The onset/ occurrence of cognitive symptoms is much later than in Lewy Body Dementia. People diagnosed with PD later in life are more at risk of developing this form of dementia. It can be confusing

Dementia with Lewy bodies (Lewy Body Dementia) shares symptoms, such as confusion and loss of memory, with Alzheimer’s disease and motor symptoms, such as gait and slow movement, with Parkinson’s disease. For that reason it can be misdiagnosed. Also patients may initially have symptoms more suggestive of these other conditions but over a course of time, begin to have more definite signs of Lewy Body Dementia. Accurate diagnosis is essential for successful treatment of the disease.
