Preliminary results from Research A study of more than 700,000 patients with traumatic brain injury (TBI) shows that people with sleep disorders are at increased risk of developing dementia.

The results show that patients with TBI diagnosed with sleep disorders are 25% more likely to develop dementia over a median follow-up of 4 years or longer. The results were similar when stratified by gender. Sleep disorders increased the risk of developing dementia by 25.5% in men with TBI and by 23.4% in women with TBI.

“The novelty of our research is sleep disorders and men. Female patient, Is independent of other known risks of dementia, “said the lead author, a related scientist at the Kite Institute, a research unit at the Toronto Rehabilitation Institute and one of the major research institutes of the University Health Network. Said Dr. Tatiana Moraeva, Principal Investigator. Mollayeva is a member of KITE’s Acquired Brain Injury & Society team and an assistant professor at the Dalla Lana School of Public Health. “We also reported for the first time the individual risks that sleep disorders and other factors pose to men, and female patients with TBI.”

During a median follow-up of 52 months, 32,834 patients (4.6%) developed dementia. Age, gender, Income level, Injury severity, and risk of known comorbidities.

“Strong connection with incidence dementia It suggests that TBI patients, both male and female, need to be more at risk for sleep disorders. “
