The American College of Rheumatology (ACR) has outlined 19 syndromes that are seen in<unk> . These syndromes encompass disorders of the central and peripheral nervous systems: *Aseptic meningitis *Cerebrovascular disease *Demyelinating syndrome *Headache *Movement disorder *Myelopathy *Seizure disorders *Acute confusional state *Anxiety disorder *Cognitive dysfunction *Mood disorder *Psychosis *Acute inflammatory demyelinating polyradiculoneuropathy *Autonomic disorder *Mononeuropathy (single/multiplex) *Myasthenia gravis *Cranial neuropathy *Plexopathy *Polyneuropathy Each of the 19 syndromes are also stand-alone diagnoses, which can occur with or without lupus. The majority of cases involve the central nervous system (CNS), which consists of the brain and spinal cord. The most common CNS syndromes are headache and mood disorder. Though<unk>  lupus is sometimes referred to as "CNS lupus", it can also affect the peripheral nervous system (PNS). Between 10-15% of people with<unk>  have PNS involvement. Mononeuropathy and polyneuropathy are the most common PNS syndromes. Other syndromes Some neurological syndromes outside of the ACR classification may also be considered<unk>  manifestations. These include neuromyelitis optica, posterior reversible encephalopathy syndrome, small fiber neuropathy, and Lambert–Eaton myasthenic syndrome.
