Hikikomori is a complex condition where a person withdraws from society and remains isolated at home for more than six months. The condition is becoming more prevalent in Western societies.

Social isolation is linked to alterations in brain structure and cognitive deficits. Additionally, social isolation can increase the risk of developing dementia as a person ages.
Social isolation has been directly linked to structural changes in brain areas associated with memory and cognitive function. Researchers report socially isolated people are 26% more likely to develop dementia later in life.
Hikikomori is a mental health disorder identified as a pathological social withdrawal. Researchers have discovered a number of biomarkers in the blood associated with hikikomori.

A combination of personality traits and childhood circumstances account for why some older people experience loneliness more than others. Lonely adults over 50 were 1.24 times more likely to have rarely, or never, had comfortable friendships during childhood, and 1.34 times more likely to have had poor relationships with their mothers as children.
