Each person is unique and will experience dementia in their own way. The different types of dementia also tend to affect people differently, especially in the early stages. Other factors that will affect how well someone can live with dementia include how other people respond to them and the environment around them.
A person with dementia will have cognitive symptoms (to do with thinking or memory). They will often have problems with some of the following:
A person with dementia will also often have changes in their mood. For example, they may become frustrated or irritable, apathetic or withdrawn, anxious, easily upset or unusually sad. With some types of dementia, the person may see things that are not really there (visual hallucinations) or strongly believe things that are not true (delusions).
Dementia is progressive, which means the symptoms gradually get worse over time. How quickly this happens varies greatly from person to person. As dementia progresses, the person may develop behaviours that seem unusual or out of character. These behaviours may include asking the same question over and over, pacing, restlessness or agitation. They can be distressing or challenging for the person and those close to them.
A common pattern for diagnosis is for the GP to make an initial assessment and then refer the person to a memory clinic or other specialist service for a more detailed assessment. A specialist doctor will have more expertise in dementia and will be able to arrange more detailed tests and brain scans, if needed. The diagnosis should be communicated clearly to the person and usually those closest to them as well. There should also be a discussion about the next steps.
The value must be greater than or equal to 1.
