Eyesight: the signs that can be early indicators of dementia – how do you recognize it?

Research shows that there are over 850,000 people in the UK with dementia. Early diagnosis means that progression can be slowed in some cases, so it’s important to spot the signs early. The NHS Health Check can help find early signs and tell you if you are at higher risk for certain health conditions that can also increase your risk of dementia.

The Royal National Institute for Blind People (RNIB) says: “Vision loss is usually underdiagnosed in people with dementia because the symptoms are difficult to distinguish. One condition can mask the effects of the other or be mistaken for the other and lead to passivity .”

The charity says people with dementia can have visual problems caused by the brain but still have healthy eyes, “that’s problems perceiving what they see rather than how sharp they see it”.

RNIB says dementias that can directly affect vision include Lewy Body, posterior cortical atrophy, Alzheimer’s disease, and vascular dementia.

The Alzheimer’s Society (AS) says, “The symptoms of vision and hearing loss may be similar to some of the early signs of dementia.”

The AS says the same of these problems can be caused by the person’s dementia.

“However, it is important to have the person’s vision tested because problems with their vision can make their confusion worse.”

The charity explains that dementia can cause someone to have hallucinations or see things that aren’t there.

“This is most common in people with dementia with Lewy bodies, although other forms of dementia can also cause hallucinations,” it says.

Visual hallucinations are the most common type experienced by people with dementia, and they can be simple, such as seeing flashing lights, or complex, such as seeing animals, people, or strange situations.

The NHS says different types of dementia can affect people differently and everyone will experience symptoms in their own way.

The health body says memory loss, difficulty concentrating and mood swings are all possible signs.

It adds: “Dementia is not a natural part of aging. That’s why it’s important to talk to a doctor sooner or later if you’re concerned about memory problems or other symptoms.”
