Early sign of Alzheimer's disease could be subtle change to your vision
One of the earliest signs that you may be suffering from Alzheimer's disease could be changes to your vision, experts say.
The heartbreaking disease is one of the most common types of and the earlier it is diagnosed the better for the patient. It can be difficult to realise someone has the condition early - and many of the symptoms are often put down to factors including depression or stress.
Alzheimer's is a progressive disease, where dementia symptoms gradually worsen over a number of years. In its early stages, memory loss is mild, but with late-stage Alzheimer's, individuals lose the ability to carry on a conversation and respond to their environment. Treatment is getting better all the time, meaning a quick diagnosis is crucial.
There are easier-to-spot signs. People may struggle to join in or follow along with a conversation and they might stop suddenly and have no idea how to continue talking or start asking questions or repeat themselves. Unfortunately, people with Alzheimer’s also may struggle with particular dates, seasons, years, and the passing of time in general.
But there are other lesser-known symptoms to watch out for. According to alzheimersresearchuk.org, a subtle change to your vision is another. They offer advice online and they state that a recent YouGov survey showed that less than half of participants could name ‘memory loss’ as an effect of dementia.

They told more about the issue, saying: "Some people may begin to experience visual disturbances. These symptoms are common in Alzheimer’s disease alongside memory problems, but can be the main issues in two different types of dementia, called dementia with Lewy bodies (DLB) and posterior cortical atrophy, PCA – a type of Alzheimer’s disease.
"Some early visual symptoms in DLB may include hallucinations, like seeing people or objects that aren’t there even though they may look real to the person experiencing the hallucination. In PCA, the visual symptoms involve problems with judging depth or making out shapes, for example having difficulty navigating steps or stairs."
There are other symptoms that should keep people on their guard. You may notice a loved one's daily tasks becoming difficult for people who are suffering from the disease. It might be that they struggle to drive or travel to a particular location. Those who have Alzheimer’s may suffer from anxiety or mood changes, and become agitated or upset in both normal situations and when out of their comfort zone. This can also lead to withdrawal from social activities and hobbies.
Misplacing things is one of the most frustrating symptoms for many sufferers as they might often put items in strange places. Unable to retrace their steps in order to find it again, can make things very tricky and this can result in outbursts as they grow confused and suspicious of others.
The society also warns that Alzheimer's can affect people’s judgement and decision-making ability. This could manifest as bad financial decisions, poor hygiene or socially inappropriate actions. The disease can hinder people’s ability to plan or follow directions which can lead to hasty decisions.
