Speaking exclusively to Express.co.uk about early symptoms of dementia is Dr Ahmad Khundakar, Head of Integrated Science and Associate Professor of Pharmacy at Teesside University.
While most people are familiar with the most common symptom of dementia being memory loss, the condition also causes problems with thinking and attention.
"Very subtle changes in behaviour in everyday life can reveal early signs of dementia," warned Dr Ahmed.
This can include examples of memory loss, such as difficulty remembering appointments, repeatedly misplacing everyday items, and forgetting the reason for entering a room.
But there is another sign of "cognitive issues", such as struggling to follow conversations.
Not being able to follow the conversation around you might be a sign of hearing loss, but this too is linked to dementia.
The Alzheimer's Society stated: "People who develop hearing problems during mid-life (aged 40 to 65) may have an increased risk of developing dementia.
"Hearing changes could also be an early symptom of dementia; there is some evidence that, if needed, using hearing aids may reduce cognitive symptoms and slow cognitive decline in people at risk of dementia, though it's not yet clear if using hearing aids can prevent dementia."
Those concerned about their hearing are able to book a free hearing test at your local opticians or your GP can refer you to an audiologist.
"Studies have shown that people who use hearing aids to manage their hearing loss are less likely to develop dementia," the charity emphasised.
Dr Ahmed added other possible signs of dementia include increased challenges with "tasks you previously handled without effort". Two examples include sudden problems with organising your schedule and preparing meals (that is, if you were originally very good at these).
"Interactions with loved ones and others might also feel different," said Dr Ahmed. "Activities that once brought happiness, such as hobbies or reading, may now feel too much."
Mr Ahmed added that those affected by the brain condition could struggle "to find familiar locations or becoming confused about the time or date".
If you suspect you or a loved one is suffering from dementia, then it's advisable to book an appointment with a local doctor.
