NEUROPSYCHIATRIC SYMPTOMS THAT MAY BE CAUSED BY AN AUTOIMMUNE REACTION
In some people, common infections can trigger a condition known as autoimmune encephalitis (AE), in which the immune system mistakenly attacks healthy cells in the brain. This, in turn, can lead to inflammation in the brain and the onset of neurologic and/or psychiatric symptoms.
Basal ganglia encephalitis, a type of AE, can occur when an infection(s) triggers antibodies that target portions of the basal ganglia region of the brain, resulting in neuropsychiatric symptoms.
Infections may be “subclinical,” meaning they are not producing outward, physical symptoms. Yet, the infections can still trigger abnormal autoimmune activity and behavioral changes.
