Diagnosing dementia

Understandably many people who experience early signs of memory loss fear a diagnosis of dementia or Alzheimer's disease. This is a normal reaction. However, an early diagnosis of dementia can have many benefits.

Diagnosing dementia can take time. An early diagnosis is always preferable. Anyone who experiences early signs of dementia should see their doctor as soon as possible to help rule out any treatable causes of dementia.

Changes in memory and thinking associated with dementia can often be subtle. It's not unusual for the early signs of dementia to be attributed to old age. Many people living with dementia experience the early signs of dementia for years before seeking medical help.

Diagnosing dementia early on can bring relief to many people who have been struggling with changes in memory and thinking. Knowing how to support and care for a loved one with dementia can improve the quality of life for many families.  

An early diagnosis of dementia also gives a person the opportunity to discuss with family how they would like to be cared for in the future. Important legal and financial decisions that affect the whole family need to be made in the early stages of dementia when a person still has legal capacity.

Drug treatments that help slow down the progression of some types of dementia are also more effective if started in the early stages of the disease.

Diagnosing dementia involves a complete medical and psychological assessment by a doctor.

A diagnosis of dementia may involve:

• Taking a medical history
• A physical exam
• Blood and urine tests
• Neuropsychological assessment
• A mental status test
• Chest x-ray, brain scans

A person may be referred to a neurologist, geriatrician, or neuropsychologist to confirm a diagnosis of dementia. It can be a frustrating and agonising experience.

Dementia can only be diagnosed by a qualified medical professional. Always seek a second opinion if you are think your concerns are not being fully investigated.
