In advice which could be of interest to international health insurance customers, people struggling with dementia have been reminded that they can benefit from a good diet.
Karen Morrison, head of service design for residential care services at Care UK, said that eating well is particularly important for mental health sufferers because a good diet will help to ward off other health problems.
International health insurance customers might want to check that they have access to care homes with healthy menus.
Ms Morrison added: "Eating too little or missing out on essential nutrients will reduce resistance to illness and may also increase confusion.
"A good intake of fluids is also essential, as being well-hydrated can assist in the reduction of some of the symptoms such as agitation, confusion and restlessness."
The comments follow a pilot training scheme organised by Care UK, which sees staff subjected to similar confusing and limiting experiences as frail people with mental health problems.
