Warning signs of Alzheimer's disease that could be spotted in the shower or bath

Alzheimer's disease, the most common cause of dementia in older adults, destroys memory and thinking skills over time. The usual early signs of dementia include memory loss, difficulty concentrating, and struggles with everyday tasks.

However, Alzheimer's specialists have identified a potential early sign that could make getting diagnosed a quicker process. While there's no cure for dementia at present, an early diagnosis can help healthcare providers slow its progression and mitigate its effects.

Memory loss is often associated with dementia, but experts from the University of Chicago have identified a significant decrease in the sense of smell as a possible early indicator. This finding suggests that individuals might be able to detect Alzheimer's disease in its initial stages, especially if they notice a diminished ability to recognise familiar smells during activities like showering.

The research is based on the link between odour recognition and memory. The team studied the olfactory function of 515 older adults, aiming to develop screening tests for the sense of smell similar to those used for vision and hearing assessments.

These tests could encourage people to look out for early warning signs, such as not being able to smell their shampoo or shower gel as strongly while bathing, reports Surrey Live. Jayant M Pinto, a professor of surgery at the University of Chicago who specialises in olfactory and sinus disease, and the study's senior author, underscored the gravity of their discovery.

He said: "This study provides another clue to how a rapid decline in the sense of smell is a really good indicator of what's going to end up structurally occurring in specific regions of the brain. We were able to show that the volume and shape of grey matter in olfactory and memory-associated areas of the brains of people with rapid decline in their sense of smell were smaller compared to people who had less severe olfactory decline."

For anyone worried about their memory or who suspects they have dementia, it's suggested they see their GP. Also, if concerned about someone else's symptoms, encourage them to book a consultation with their doctor and offer to accompany them.

Statistics suggest that there are upwards of 944,000 individuals living with dementia in the UK today, and these figures are projected to rise. The primary cause of dementia is Alzheimer’s disease, followed by others like vascular dementia, dementia with Lewy bodies, and frontotemporal dementia.

According to the NHS, common symptoms of dementia can include memory loss, slower thinking speed, reduced mental agility, mood changes, and difficulties with daily tasks. However, these aren't the only indicators to watch out for - a diminished sense of smell could also be a potential red flag.
