- 8. Pathophysiology Presymptomatic hyperexcitabilty increasesbrain stem response to triggers Release of Neurotransmitters (5-HT, NE, DA, GABA, Glutamate, NO, CGRP, Substance P, Estrogen) Neurotransmitters activate the Trigeminal Nucleus Activation of Hypothalamus (Hypersensitivity) Activation of Area Postrema Activation of cervical trigeminal system (Muscle spasm) Dilation of Meningeal blood vessels (Throbbing) Activation of Cortex and Thalamus (Head pain)
- 9. CLINICAL FEATURES • Clinicalmanifestations of migraine headache are triggered by missing meal, intense stress, thymine rich food and sleep alteration – Anorexia, – Nausea, vomiting, – Visual disturbances
- 11. Management • Vasoconstrictor –sumatriptan • Triptan nasal spray in pt with nauseaa and vomiting. Nursing care • Should not given in hypertension , ischemic heart diseases • Excesss dose can cause tremor
- 12. TENSION HEADACHE : •Is the most common type of headache, is characterized by bilateral location. It is usually mild or moderate intensity and not aggravated by physical activity. Tension type headache is sub categorize as – Infrequent episodic – Frequent episodic – Chronic

It may be triggered by or get worse with stress, fatigue, noise, or glare. • There may be difficulty sleeping. • People with tension headaches try to relieve pain by massaging their scalp, temples, or the bottom of the neck. • Sleep disturbances • Photophobia – sensitivity to light • Phonophobia – sensitivity to sound
- 15. Management • Over-the-counter (OTC)pain medicines, such as aspirin, ibuprofen, or acetaminophen • Narcotic pain relievers are generally not recommended • Muscle relaxers • Tricyclic antidepressants to prevent recurrences
- 16. Health Education • Keepwarm if the headache is associated with cold. • Use a different pillow or change sleeping positions. • Practice good posture when reading, working, or doing other activities. • Exercise the neck and shoulders frequently when working on computers or doing other close work. • Get plenty of sleep and rest.
- 17. Secondary Headache • Asecondary headache is present because of another condition. The management of secondary headache focuses on diagnosis and treatment of the underlying condition. The types of secondary headache are • Systemic infection E.g. Meningitis, • Head injury • Vascular disorders E.g. Aneurysm Rupture, Stroke • Subarachnoid hemorrhage • Brain tumor
- 18. CLUSTER HEADACHE: • Acluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop

- 20. Etiology • Exact causeis unknown • Sudden release of histamine, serotonin • Hypothalamic issues • Others – Alcohol and cigarette smoking – High altitudes (trekking and air travel) – Bright light (including sunlight) – Exertion (physical activity) – Heat (hot weather or hot baths) – Foods high in nitrites (bacon and preserved meats) – Certain medicines – Cocaine
