Past research has linked to certain mental health conditions, such as depression and anxiety, to an increased risk for dementia.
A new study has found that people who have multiple mental health conditions have a higher risk of developing dementia than those with one.
Researchers report that this risk percentage increases with each additional concurrent mental health disorder.
Past research has linked certain mental health conditions, such as depressionTrusted Source, anxiety, post traumatic stress disorder (PTSD), and bipolar disorder to an increased risk for dementia — a neurological condition impacting about 57 million peopleTrusted Source globally.
Scientists believe that mental health issues may be correlated with a higher dementia risk due to chronic inflammation and structural brain changes, as well as an increase in the protein amyloid-betaTrusted Source in the brain, which is considered a hallmark of a type of dementia called Alzheimer’s disease.
New study recently published in the journal BMJ Mental Health reports that people who have multiple mental health conditions have a higher risk of developing dementia than those with one.
Researchers say this risk percentage increases with each additional concurrent mental health disorder.Researchers analyzed health data from more than 3,600 adults ages 45 and older from the psychiatry department of Bicêtre Hospital in France.
Study participants all had at least one psychiatric disorder, including depression, anxiety, psychosis, substance use disorder, personality disorder, or bipolar disorder. Researchers also recorded whether or not participants had dementia or cognitive impairment.
At the study’s conclusion, scientists found that participants with two psychiatric disorders were twice as likely to be diagnosed with dementia than those with only one. Those with three mental health issues were four times more likely to have dementia. And those with four or more psychiatric disorders had an 11 times greater chance of being diagnosed with dementia than those with one mental health concern.
