Different types of dementia

2024-01-10

Dementia is an umbrella term for over a hundred different neurological conditions. The most common form is Alzheimer’s disease, accounting for 60–80% of all cases. Other common types include vascular dementia, Lewy body dementia and frontotemporal dementia.

There are several different types of dementia, each with their own unique characteristics and causes

Dementia is an umbrella term that describes a range of neurological conditions leading to impaired memory, cognitive function, and the ability to carry out everyday activities. Understanding the different types of dementia is important for providing the right care and support:

  1. Alzheimer’s disease: Alzheimer’s is the most common form of dementia, accounting for approximately 60–80% of all cases. It is a progressive disease leading to gradual deterioration of memory, thinking and behaviour. The cause is not fully understood, but the accumulation of plaques and tangles in the brain is believed to play an important role.
  2. Vascular dementia: Vascular dementia occurs when blood flow to the brain is reduced, usually due to stroke or small vessel disease. Symptoms can vary depending on which area of the brain is affected, but may include memory loss, difficulty with planning, and challenges with everyday tasks.
  3. Lewy body dementia: Lewy body dementia is caused by accumulations of the protein alpha-synuclein in the brain, leading to gradual deterioration of cognitive and motor functions. Symptoms can include memory loss, hallucinations, movement disorders and sleep disturbances.
  4. Frontotemporal dementia (FTD): FTD is a group of disorders affecting the frontal and temporal lobes of the brain, resulting in changes in personality, behaviour and language. Symptoms can include lack of empathy, impulsivity, apathy and difficulty finding words.
  5. Parkinson’s disease dementia: Many people with Parkinson’s disease also develop dementia in the later stages. This type of dementia is characterised by gradual deterioration of cognitive functions, including memory loss, difficulty concentrating and problem-solving challenges.

Dementia can present differently in every individual

It is important to remember that dementia can have different symptoms and progressions for each individual, and that correct diagnosis and treatment are essential for providing appropriate care and support. Read more about what dementia is for a broader overview.

Sensorem’s safety alarm has GPS positioning, medication reminders and automatic fall alarm

Sensorem’s personal alarm is an example of a technical aid specially developed for people with dementia. The personal alarm works outdoors and has built-in GPS positioning so that relatives can see the user’s position on a map in the Sensorem app. Relatives are automatically called by the personal alarm (two-way communication) if the user leaves a predetermined geographical area. The personal alarm also has medication reminders, which means that the watch emits a sound and tells the user that it is time to take their medication. The personal alarm can also alert automatically in the event of a fall with the built-in fall sensor.
