How is it diagnosed?

The doctor first conducts a thorough physical examination of the patient and takes his medical and family history. The physical examination includes a detailed neurological examination. The latter consists of examinations for alertness, muscle strength, coordination, reflexes and response to pain. Any swelling of the eyes and visual disturbances is also ascertained.

The doctor may ask for tests like CT or MRI scan to study the tissues of the brain. These procedures help to identify any changes in the brain tissues, and outline any abnormal growth. Other tests that may be requested by the doctor are EEG, angiogram and a skull X-ray.


When should the doctor be consulted urgently?

Persistent or increasing frequency of headache specially if it is associated with vomiting, blurring or double vision, weakness of any part of the body, epileptic fits, difficulty in speaking, instability of gait. Change of behaviour, memory impairment with or without the above symptoms should also prompt expert consultation.
