Citing work pressure as the reason or the distance from home, one in eight adults have admitted to not seeing their parents for over an year.
The survey by elderly charity Christies found that one in 10 adults only speak on the telephone with their mother or father once every four weeks.
Although, they live on average just 66 miles away, 12 per cent of ageing parents only get to see their sons, daughters and grandchildren three times a year.nd the reasons that prevent a visit to elderly parents came out to be-long office hours, children's homework and after-school activities.
One third of people over the age of 40 blamed their hectic lifestyles for not making time while 43 per cent said they lived too far away to make more of an effort.
Meanwhile only one in five people visited their parents once a month.
"It's clear many elderly parents and grandparents are being forgotten about as we carry on with our hectic and stressful lives," the Telegraph quoted Hugh Gathorne-Hardy, Chairman of Christies Care as saying.
"Too many are seen too little throughout the year and a significant number are left feeling isolated, with little human contact," he added.
However, despite the results, it was found that 36 per cent of adults are currently concerned for their parent's well being.
The survey of 3,000 adults was carried out to mark the launch of a new guide 'Paying for Care: Your options explained' published by Christies Care.
