Abstract
A woman affected by multiple cranial nerve palsy developed several episodes of total insomnia and respiratory crises resulting from central breathing depression associated with dysautonomic symptoms. Oligoclonal IgG bands were present in her cerebrospinal fluid, and immunohistochemistry showed increased binding of serum and cerebrospinal fluid on γ‐aminobutyric acid‐ergic, synapse‐rich neuronal cells. Immunosuppressive treatment and plasma exchange were followed by clinical improvement, with restoration of sleep architecture and disappearance of respiratory crises, suggesting autoimmune pathogenesis of the syndrome.
