What are the risks of leaving an elderly person with dementia alone at home? – Dementia Care Support Guide

Leaving a person with dementia (mid-stage onward) at home alone can pose serious safety risks. Leaving an elderly person with dementia alone at home is not just risky, it’s a matter of utmost importance.

Is it illigal to leave a dementia patients alone?
No! And certainly not safe, especially in homes with stairs, multiple rooms, and a fully equipped kitchen.

Caring for a loved one with this condition requires constant vigilance and support, as they may become disoriented, confused, or forgetful. In this article, we will delve into the reasons why leaving someone with dementia alone is not an option. Dementia affects millions of people worldwide, robbing them of their memory, cognitive abilities, and independence. Without proper supervision, people with dementia are at a higher risk of accidents, injuries, or wandering away.

Furthermore, the emotional toll of isolation can exacerbate their symptoms and lead to increased agitation, anxiety, and depression. The need for constant care and companionship becomes even more critical as their condition progresses. As dementia progresses, individuals may engage in behaviours that could potentially harm themselves or others.

Therefore, when caring for a loved one with dementia, it is imperative to prioritise their safety and well-being, particularly if they reside alone. 

To ensure their safety, it is crucial to assess their abilities and needs and put appropriate safety measures in place. By taking these necessary precautions, you can help provide a safe and secure environment for your loved one with dementia and give yourself peace of mind knowing that they are well protected.

As a carer/caregiver or family member, it is essential to take proactive steps to ensure dementia patients’ safety at home, such as installing safety devices, setting up remote monitoring, and ensuring that they have 24/7 supervision. Doing so can provide peace of mind and security for both the dementia patient and their loved ones.

While leaving an elderly person with dementia alone at home may seem like an easy solution, it is important to understand the potential risks that come with it, including:


Dementia can cause problems with balance and coordination, increasing the risk of falls, which could lead to serious injuries.


The person might forget to turn off appliances, leave the water running, or engage in unsafe activities, leading to accidents or household hazards.

Medication Errors:

Dementia can affect memory and the ability to manage medications correctly, leading to missed doses, double doses, or incorrect administration.


People with dementia might wander and become lost, putting them at risk of getting injured, becoming disoriented, or encountering dangerous situations.

Malnutrition and Dehydration:

Forgetting to eat and drink regularly can result in malnutrition and dehydration, affecting their overall health.

Confusion and Agitation:

Being alone can increase confusion and agitation in individuals with dementia, leading to distressing episodes or behaviours.

Social Isolation:

Solitude can lead to increased feelings of loneliness and depression, impacting mental and emotional well-being.

Vulnerability to Scams:

Individuals with dementia might be more susceptible to scams, financial exploitation, or manipulation by strangers.

Inability to Seek Help:

They might be unable to communicate effectively in cases of emergencies or health issues.

Neglecting Personal Care:

Forgetfulness and confusion can lead to neglect of personal hygiene and self-care routines.

Considering these risks, it’s essential to ensure the safety and well-being of elderly individuals with dementia through appropriate care arrangements, regular monitoring, and support from caregivers or professionals.
