“When you see a person living with dementia, you have seen just one.”

Every person living with dementia is unique and does not present the same symptoms. The needs and manifestations vary between individuals although there are some common symptoms.

Signs and symptoms of dementia include (but not limited to):

• Memory loss (forgetfulness) that occurs gradually, and worsens progressively with time. Immediate and short-term memory loss occurs first.
• Difficulty in communication.
• Problems recognising familiar faces, places, or items.
• Worsening of problem-solving abilities and increasing disorganisation.
• Problems with daily activities such as dressing and using utensils during mealtimes.

In addition, changes to moods and behaviours may also occur, such as:

• Depression
• Agitation
• Hallucinations
• Anxiety
• Paranoia
• Sleep problems
