The word dementia is a general term that refers to many different diseases. Different types of dementia are caused by different physical changes to the brain. Some dementias are reversible, meaning that they can be treated and cured. Some are irreversible, meaning that there is no cure yet. 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.
