Convulsive syndrome in children is a typical sign of epileptic seizures, spasmophilia, toxoplasmosis, inflammatory diseases of the brain and meninges (encephalitis, meningitis) and other diseases.
Migraine status - more pronounced and prolonged in comparison with the usual attack of migraine symptoms. The development of migraine is due to a hereditary predisposition to inadequate regulation of the tone of the vessels of the brain (spasm and subsequent vasodilation) in response to the action of various factors of the external and internal environment.
Acute polyneuropathy, or Guillain-Barre syndrome, is an autoimmune inflammation of the peripheral and cranial nerves, with the defeat of myelin sheaths and the development of acute neuromuscular paralysis.
Edema of the brain is a universal nonspecific reaction of the brain characterized by disturbances of water-ion equilibrium in the system of "neuron-glia-adventitia".
Coma is a clinical condition caused by impaired CNS functions. Violations as their severity worsens lead to a loss of the coordinating role of the central nervous system, which is accompanied by spontaneous self-organization of vital organs and functional systems. They, in turn, lose the ability to participate in the processes of homeostasis and homeoresis of the development of the body. Loss of consciousness is a consequence of the dysfunction of the reticular activating system and neurons of the brain, as well as the dislocation of its structures.
Thyrotoxic crisis is a life-threatening complication of untreated or improperly treated thyrotoxicosis, manifested by severe multi-organ dysfunction and high lethality.
The hypercalcemic crisis is a life-threatening emergency, diagnosed with an increase in the level of calcium in the blood above 3 mmol / l (in term infants - above 2.74 mmol / l, and in premature infants - above 2.5 mmol / l).
Hypocalcemic crisis - a condition characterized by increased neural-reflex excitability and attacks of tetany due to persistent decrease in the level of calcium in the blood.
