Dr Jun Wen, one of the study’s authors, told Medical News Today: “All tourism experiences offer elements of anticipation and planning, both of which stimulate brain function.
“Exercise is often an important component of tourism experiences, and it is frequently included in dementia intervention plans.
“Tourism experiences such as a beach visit offer dementia patients sensory stimulation, boosting one’s mood, exercise, music therapy, and instilling a sense of freedom as non-medicine dementia interventions.
“Group travel may simulate psychological interventions, and music at a destination is in line with music therapy programs for those with dementia.”
Dr Wen added that it wouldn’t be possible for every dementia patient to travel overseas but a team approach could help.
He said: “From a tourism destination perspective, many opportunities exist for marketing a destination as ‘dementia-friendly.”
In the UK, an estimated 850,000 people are living with dementia, and around seven percent of over 65s have the condition.
Travel can also help to improve mental health more generally as well as boost physical wellbeing.
