PANS and PANDAS are conditions that can cause sudden and severe behavioural, emotional, and cognitive changes in children. Onset of symptoms is acute, but the condition is chronic. PANS and PANDAS are triggered by a misdirected immune response to disturbances of metabolism, infections (eg Lyme, EBV, chickenpox, flu, strep ) or other inflammatory reactions (eg mould, parasites, histamine etc) producing a constellation of symptoms which are difficult to navigate and require a multifaceted approach to help. Homeopathy is very effective in treatment of PANS and PANDAS through addressing the route cause, and works well with complementary therapies such as naturopathic nutrition to help your child recover.
