Could an infection be affecting your mental health?
In a 2024 study, Bartonella DNA was found nearly three times as often in adults with psychosis than in adults without psychosis.
Bartonella infection can affect the brain and nervous system.
It has been linked to neurological and neuropsychiatric symptoms, including confusion, seizures, severe anxiety, agitation, depression, and psychosis.
The study found a connection – not proof that Bartonella is the sole root cause behind these symptoms. Mental health conditions can have different causes and variables.
But when infection is never considered, patients may miss the chance to receive appropriate care.
And that full picture is critical to diagnosis and treatment, whether symptoms are psychological, physical, or both.
