  1. Patho-physiologyof nervous SystemTalk 2 –Syndromes in neurosciences Petr Maršálek Dept pathological physiology 1.Med. F. CUNI

  2. Talks on NS Talk 1 -Pain and Motor disorders Talk 2 - This - Syndromes in neurosciences Talk 3 - Disorders of special senses Talk 4 - Cognitive functions, dementias, etc. of 23

  3. Syndromes 1) hypoxia of CNS 2) carbon mono-oxide poisoning 3) liquor circulation disorders 4) cerebral oedema 5) intra-cranial hypertension 6) intra-cranial hemorrhage 7) systemic neuro-muscular plate disorders 8) seizures – epilepsy and migraine 9) sleep/ wake cycle disorders 10) vomiting as a sign of NS of 23

  4. Cerebrovascular brain disease. Hypo-perfusion, brain hypoxia of 23

  5. Topicsigns of 23

  6. Acute carbon-monooxide poisoning of 23

  7. Acute CO poisoning – blood gases affinity to Hb of 23

  8. Blood gases of 23

  9. of 23

  10. of 23

  11. of 23

  12. Intracranialhypertension,subjective signs headache, nausea, vomiting, blurred vision objective signs vomiting, papilla nervi optici (n. II) bradycardia, hypertension, loss of consciusness, coma of 23

  13. Obstructive hydrocephalus of 23

  14. Angiografic findingsin intra-cranial expansions(Bartko, 1985) of 23

  15. Intracranial hemorrhage of 23

  16. Glasgow coma scale of 23

  17. Disorders of Neuromuscular transmission of 23

  18. Disorders of Neuromuscular transmission of 23

  19. Artificial ventilation/ Iron lung • Ventilation can be delivered via: • Hand-controlled ventilation such as: • Bag-Valve-Mask Resuscitator Continuous-flow or Anaesthesia (or T-piece) bag • A mechanical ventilator. • Iron lung is a historical type of mechanical ventilator of 23

  20. Demyelination – sclerosis multiplex of 23

  21. EEG atlas B Normal findings: EEG waves: Alpha waves, 8-13 Hz, parieto-occipital region, marked in closed eyes Beta waves, 14-30 Hz, frontal region Gamma waves, 40-60 Hz, are not regularly used due to interference with electric power net. Delta waves, < 4 Hz, e.g in synchronous phase of sleep. Theta waves, 4-7 Hz, e.g in synchronous phase of sleep. of 23

  22. Epilepsy: Cortico- Thalamic and Thalamo-cortical feedback system modulating sensoryinputs of 23

  23. Migraine – phosphenes of 23

  24. Migraine - scotomas of 23

  25. Sleep/ wake cycle of 23

  26. Sleep/ wake cycle + narcolepsy and reticular formation effects of 23

  27. Vomiting center/ causes of vomiting of 23

  28. 1 Intracranial hypertension - irritation 2 Drugs – nicotine, apomorphine, etc 3 Kinetosis 4 Radiation disease 5 Pregnancy 6 Psychogenic 7 Pharyngeal irritation 8 Local gastric irritation – food poisoning 9 Peritoneal irritation, ileus 10 Other internal organs – heart etc Causes of vomiting of 23
