Feeling forgetful or confused? Finding out what is wrong is the first step to getting help.
In this section, we offer help sheets on every topic, issue, and concern relating to dementia that you might need support on.
Information, services and support that you can access through Alzheimer’s Australia.
Alzheimer's Australia provides a range of sensitive and flexible services to support people with any type of dementia, their families and carers throughout the illness.
Alzheimer’s Australia is committed to contributing towards Australian dementia research.
Your help and support is vital to Alzheimer's Australia.
Dementia Awareness Month is held across the country during the month of September. In 2014 the theme is 'Creating a dementia-friendly nation'.
Alzheimer's Australia administers leading edge national dementia programs and services.
Alzheimer’s Australia welcomes your feedback and enquiries. We aim to answer them as quickly as possible.
The first step towards a diagnosis is to talk to your doctor about your concerns. It is a good idea to take a close family member or friend along to help provide the doctor with all the information they need.
It is also a good idea to take along a list of the memory and thinking changes that have been concerning you, including when you first noticed them and how often you notice them. You should also take a list of the medications you are taking or take your medications with you.
Your doctor may assess you and/or may refer you to a specialist such as a geriatrician (a specialist in illnesses and disabilities in older people), a neurologist (a specialist in disorders of the brain and nerves), or a psychiatrist (a specialist in disorders of emotion and behaviour).
The doctor usually spends some time discussing your medical history and gathering information about your changes in memory and thinking.
The symptoms of dementia can be due to a number of other possible causes, such as vitamin deficiency, infection, metabolic disorders and side effects from drugs. These other causes are often easily treated. Therefore, an early step in diagnosing dementia is to rule out these causes through a physical examination, blood tests and urine tests.
Routine laboratory tests used in the diagnosis of dementia include:
Cognitive tests are used to measure and evaluate cognitive, or ‘thinking’, functions such as memory, concentration, visual-spatial awareness, problem solving, counting and language skills.
Most doctors use short cognitive screening tests when assessing these functions. If more detailed testing is required you will be referred to a neuropsychologist – a psychologist specialising in the assessment and measurement of cognitive function.
Cognitive tests are vital in the diagnosis of dementia and are often used to differentiate between types of dementia. They can also be used to assess mood and may help diagnose depression, which can cause symptoms similar to those of dementia.
Special arrangements can be made for testing people whose first language is not English or who have communication difficulties. Your doctor can give you advice about this.
Mini-Mental Status Examination (MMSE) This test is usually conducted by your doctor or specialist in their office and takes around 5 minutes to complete. The MMSE is the most common test for the screening of dementia. It assesses skills such as reading, writing, orientation and short-term memory.
Alzheimer’s Disease Assessment Scale-Cognitive (ADAS-Cog) This 11-part test is more thorough than the MMSE and can be used for people with mild symptoms. It is considered the best brief examination for memory and language skills. It takes around 30 minutes and is usually conducted by a specialist in their office, or you may be referred to a psychologist for the test. Neuropsychological Testing This involves a number of very sensitive tests administered by a neuropsychologist (a psychologist who has been trained in the assessment of dementia and other disorders of the brain). A typical testing session will take between at least 2 hours and may be conducted over more than one visit. A variety of tests will be used and may include tests of memory such as recall of a paragraph, tests of the ability to copy drawings or figures and tests of reasoning and comprehension.
Radiological tests Standard X-rays may be taken and those who smoke will commonly require a chest X-ray to rule out lung cancer, which may be causing a secondary brain tumour. Brain imaging techniques Various brain-imaging techniques are sometimes used to show brain changes and to rule out other conditions such as tumour, infarcts (strokes – dead areas of brain tissue) and hydrocephalus (fluid on the brain); these include:
Obtaining an early and accurate diagnosis can improve the quality of life for people with dementia. Talk to your doctor about treatment and ongoing assessment. Support and information is available through Alzheimer’s Australia.
