Loneliness may play a vital role in the development of Alzheimer's disease after a new study published in the Journal of Neurology, Neurosurgery and Psychiatry revealed that people who feel lonely were more likely to be diagnosed with the neurodegenerative disease compared to those who do not feel lonely.
The study was conducted by researchers at VU University Medical Centre in Amsterdam who observed more than 2,100 people over 65 years of age in the Netherlands who did not have any symptoms of the disease.
They were then followed up three years later and the researchers found that those who felt lonely were 65 percent, or 1.64 times, more likely to develop Alzheimer's disease.
"Individuals with feelings of loneliness remained 1.64 times more likely to develop clinical dementia than persons who did not feel lonely. In contrast, objective aspects of social isolation no longer showed such an association" the researchers wrote in their report.
