Dementia Overview


Dementia is an umbrella term for a variety of brain disorders. Symptoms include loss of memory, judgment and reasoning, and changes in mood and behaviour. Brain function is affected enough to interfere with a person's ability to function at work, in relationships and in everyday activities.

Several conditions produce symptoms similar to dementia. These can include depression, thyroid disease, infections or drug interactions. Early diagnosis is essential to make sure that people with these conditions get the right treatment.

If the symptoms are caused by dementia, an early diagnosis will mean early access to support, information, and available treatment options.

Regardless of the type of dementia, people who have dementia and those who care for them can get information and support from the Alzheimer Society.
