Small changes in behaviour can sometimes reveal more about our health than we realise.
Habits that appear harmless on the surface may occasionally point to something deeper happening in the body.
Health experts say certain repeated movements can be linked to neurological conditions, including dementia.
According to dementia specialists, a subtle behaviour involving the hands may appear in some people living with the condition, particularly in its later stages.

When restlessness appears
Dementia is a broad term for conditions that damage brain function and affect memory, thinking and behaviour.
The Alzheimer’s Society reports that around 900,000 people in the UK are currently living with the illness.
While memory problems are often the most recognised symptom, behavioural changes are also common as the disease progresses.
Specialists say some individuals with advanced dementia may repeatedly wring or rub their hands. This action can be a sign of restlessness or discomfort.

What may cause it
Researchers say restlessness in dementia can occur for many reasons. Physical discomfort, pain or the need for movement may all play a role.
Environmental factors can also trigger agitation. Loud surroundings, unfamiliar spaces or too much activity may make someone feel unsettled.
Common signs linked to this type of restlessness include:
- repeated hand movements
- picking at clothing or nearby objects
- pacing around
- increased confusion later in the day
Ways to respond
Experts recommend first identifying possible triggers behind the behaviour. In many cases, small adjustments to daily routines can help reduce agitation.

Activities that keep the hands occupied, such as simple hobbies or familiar objects, may provide comfort. Health organisations advise contacting a doctor if symptoms appear or worsen.
