What is Dementia?

Dementia is a term used to describe a range of disorders or conditions that are affecting the brain. There are several types of dementia, the most common and well known one is Alzheimer's disease. You can have Dementia at any age, not just as you get older, and everyone diagnosed with dementia will experience their own unique symptoms

What are the most common types of Dementia?

The most common types of Dementia are as follows:

Alzheimer's Disease - symptoms are usually mild to begin with and then worsen over time. (Difficulty with language, depressed or agitated and may withdraw from family and friends, memory lapses, problems with special awareness, difficulty making decisions, problem solving and/or disorientation of time or place, a person not recognizing a familiar face.)

Vascular Dementia - caused by small blood clots preventing oxygen getting to the brain. (Progression can be quite erratic as a person my not have a series of blood clots for sometime. People suffering will usually appear to be 'getting better', this is usually temporary, as the damage to the brain can eventually lead to difficulties; e.g. with daily living, attention, memory, decision making and motivation.) 

Frontotemporal - More common under the age of 65. Frontotemporal Dementia represents a group of conditions which are caused due to nerve cells in the brain dying and the nerve pathways becoming damaged in the frontal and temporal lobes of the brain. (Behavioural Variant Frontotemporal Dementia symptoms can be: changes in behavior or personality, apathy, obsessive or repetitive behaviours, loss of empathy, changes in appetite, difficulties making decisions, problem solving and concentration.)(Primary Progressive Aphasia, which consists of Semantic Dementia and Progressive Non Fluent Aphasia can have the following symptoms: language difficulties, speech or grammar problems, reduced understanding and difficulty recognizing familiar faces or objects.)

Dementia with Lewy bodies - Dementia with Lewy Bodies is caused by a build up of clumps and proteins in nerve cells in the brain, known as Lewy Bodies. (Symptoms of this are: fluctuating alertness, confusion and concentration levels, memory issues, mood changes, struggling with problem solving, spatial awareness, difficulty doing everyday tasks, tremors, slower movement, sleep disturbance, unsteadiness, an increase in falls and visual hallucinations.
