Tension headaches: They are the most general form of a primary headache. Such headaches normally begin gradually in the middle of the day.

Migraines: It may cause a pulsating, throbbing pain usually only on one side of the head.

Rebound headaches: These headaches stem from an excessive use of medication to treat headache symptoms.

Cluster headaches: It usually last between 15 minutes and 3 hours, and they occur suddenly once per day up to eight times per day for a period of weeks to months.

Clinical explanation –

(1) Pain-sensitive intracranial structures are:

  • The large cranial venous and their tributaries from the surface of the brain;
  • Dural arteries,
  • The dural floor of the anterior and posterior cranial fossae; and,
  • arteries at the base of the brain.

(2) Extradural and subdural hemorrhage are both common. An extradural hemorrhage can be distinguished from a subdural hemorrhage because of the following differences.

  • It is less common.
  • The hemorrhage is arterial (middle meningeal, whereas it is venous in subdural hemorrhage.
  • Symptoms of cerebral compression are late.
  • There is no lucid interval in the case of a subdural hemorrhage. In an extradural hemorrhage, a lucid interval is present.

This is a temporary phase of consciousness between the earlier unconsciousness of cerebral concussion and the later unconsciousness of cerebral compression.
