Headache: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

Initially, migraine headaches usually produce unilateral, pulsating pain, which later becomes more generalized. They’re commonly preceded by a scintillating scotoma, hemianopsia, unilateral paresthesia, or speech disorders. The patient may experience irritability, anorexia, nausea, vomiting, and photophobia. (See Clinical features of migraine headaches.)

Both muscle contraction and traction-inflammatory vascular headaches produce a dull, persistent ache, tender spots on the head and neck, and a feeling of tightness around the head, with a characteristic “hatband” distribution. The pain is usually severe and unrelenting. If caused by intracranial bleeding, these headaches may result in neurologic deficits, such as paresthesia and muscle weakness; narcotics may fail to relieve pain in these cases. If caused by a tumor, pain is most severe when the patient awakens.

West Nile encephalitis: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

Mild infections of the virus are more common and include fever, headache, and body aches, usually accompanied by a skin rash and swollen lymph glands. Severe infections can be manifested by headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, occasional convulsions, paralysis and, rarely, death.

The incubation period for West Nile encephalitis is anywhere from 5 to 15 days after exposure. Most patients who are bitten by an infected mosquito won’t develop symptoms. It's estimated that only 1 in 300 people who are bitten by an infected mosquito will actually get sick.

Encephalitis: Signs and symptoms
(Handbook of Diseases)

All viral forms of encephalitis have similar clinical features, although certain differences do occur.

Usually, the acute illness begins with sudden onset of fever, headache, and vomiting and progresses to include signs and symptoms of meningeal irritation (stiff neck and back) and neuronal damage (drowsiness, coma, paralysis, seizures, ataxia, and organic psychoses). After the acute phase of the illness, coma may persist for days or weeks.

The severity of arbovirus encephalitis may range from subclinical to rapidly fatal necrotizing disease. Herpes encephalitis also produces signs and symptoms that vary from subclinical to acute and commonly fatal fulminating disease. Associated effects include disturbances of taste or smell.

Headache: Signs and symptoms
(Handbook of Diseases)

Migraine headaches and muscle contraction headaches have different signs and symptoms.

Migraine headache

Initially, a migraine headache usually produces unilateral, pulsating pain that later becomes more generalized. The headache is commonly preceded by a scintillating scotoma, hemianopsia, unilateral paresthesia, or speech disorders. The patient may experience irritability, anorexia, nausea, vomiting, and photophobia. (See Clinical features of headache, page 364.)

Muscle contraction headache

A muscle contraction headache produces a dull, persistent ache; tender spots on the head and neck; and a feeling of tightness around the head, with a characteristic “hatband” distribution. The pain is usually severe and unrelenting.

If caused by intracranial bleeding, the muscle contraction headache may result in neurologic deficits, such as paresthesia and muscle weakness; narcotics fail to relieve the pain in these cases. If the headache is caused by a tumor, pain is most severe when the patient awakens.

Severe infections present with symptoms such as headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, occasional convulsions, paralysis and, rarely, death.

The incubation period for West Nile encephalitis is 5 to 15 days after exposure.

CLINICAL TIP: Researchers estimate that only 1 in 300 people who are bitten by a mosquito infected with WNV actually develops the disease.
