[Lyme borreliosis in neurology and psychiatry].

Neurological manifestations of Lyme disease are as multifarious as the entire spectrum of this common infection. In stage I, fibromyalgia and, more rarely, painful muscular fasciculation, dominate the clinical picture. In the individual case, mild psychic abnormalities may already be observed. Characteristic of the 2nd stage is lymphocytic meningopolyneuritis. Involvements of the CNS are expressed not so much in focal deficits, as in diffuse psychopathological disorders. In stage 3, CNS manifestations are characterized by chronic, in part multifocal, encephalitides and encephalomyelitides, isolated transverse myelitides and cerebral vasculitic disorders. The clinical symptomatology may be dominated by severe psychiatric syndromes. Connatal and subclinical latent infections of the nervous system with Borrelia represent special forms.
