It depends on the person’s stage, behaviour, and home environment, but it is often not safe for long periods. Risks include falls, leaving appliances on, wandering, forgetting medication, and becoming frightened or confused. Some people with very mild dementia may manage briefly if the home is secure and routines are simple. Still, it is important to assess judgment, memory, and emergency response ability. If there is any concern, arrange supervision, check-ins, or other support. Safety should come before independence when the risks are high.
