- Porphyria or acute intermittent porphyria (AIP); genetic disease with autosomal dominant inheritance; patients with this disease have a 50 percent reduction in the activity of the enzyme porphobilinogen deaminase (PBG-D), which is sufficient for porphyrin synthesis. Triggers of a porphyria attack, which can last a few days but also months, are infections, drugs or alcohol. The clinical picture of these attacks presents as acute abdomen or neurological deficits, which can take a lethal course. The leading symptoms of acute porphyria are intermittent neurologic and psychiatric disturbances. Autonomic neuropathy is often in the foreground, causing abdominal colic (acute abdomen), nausea (nausea), vomiting or constipation (constipation), as well as tachycardia (heartbeat too fast: > 100 beats per minute) and labile hypertension (high blood pressure).

- Guillain-Barré syndrome (GBS; synonyms: Idiopathic polyradiculoneuritis, Landry-Guillain-Barré-Strohl syndrome); two courses: acute inflammatory demyelinating polyneuropathy or chronic inflammatory demyelinating polyneuropathy (peripheral nerve disease); idiopathic polyneuritis (multiple nerve disease) of spinal nerve roots and peripheral nerves with ascending paralysis and pain; usually occurs after infection
- Neuroborreliosis – disease symptoms of the nervous system caused by Lyme disease.
- Neuropathy (disease of the peripheral nervous system) with distal symmetrical distribution type:
- Toxic polyneuropathy due to alcohol or drugs.
- Deficiency neuropathy due to vitamin B deficiency or malabsorption
