Autoimmune encephalitis (AE) can produce a very wide range of neuro-psychiatric symptoms. A major challenge in diagnosis is that different symptoms may appear at different times and different levels of intensity, so that the disease may mimic many other disorders. Some patients initially present with either neurological or psychiatric symptoms, further complicating diagnosis.
Symptoms associated with AE can include:
weakness or numbness of part of the body
loss of balance
slowed or blurred speech or loss of ability to speak
