Some new data suggests that long-term ownership of a dog may help to offset the kinds of cognitive declines that we see in age-related dementia and Alzheimer’s disease.
Given the fact that our population is living longer, coping with the reduced mental abilities of older individuals is becoming a larger problem. A recent study suggests that in the U.S., one in seven people, aged 71, is suffering from dementia or Alzheimer’s disease. That number increases over time and by age 90 nearly one in three people may be affected. These dementias are characterized by a group of progressive, incurable neurological syndromes associated with irreversible memory loss and diminished cognitive abilities.
Dementia Is Not Inevitable
Research suggests that approximately one-third of dementia cases are associated with causes that can be controlled or modified, including physical inactivity, social isolation, cardiovascular disease, depression and chronic stress. Therefore, to try to reduce the effects of dementia, medical and psychological researchers are studying lifestyle habits that may decrease the likelihood or severity of such conditions. The surprise is that this is where dog ownership comes into play.
Interaction with a pet dog in the household is an important aspect of an older person’s lifestyle that could influence their cognitive health. Living with a pet has been shown to have beneficial effects on many aspects of our physical and psychological welfare. Dog ownership is associated with better cardiovascular health, decreased loneliness and lowered likelihood of depression. It is well-established that a pet dog provides emotional support which in turn buffers an individual against the effects of stress.
