A cluster headache is a type of headache that is severe and recurring and generally occurs on one side of the head. Cluster headaches occur in "clusters" of episodes that recur over days or weeks. Cluster headaches can be severe enough to disrupt everyday life, such as work, school, relationships, and social activities. Additional symptoms of cluster headaches can affect the eye and nose as well. For more information on symptoms and complications, refer to symptoms of cluster headache.
Cluster headaches are often, but not always, triggered by one or more specific substances or situations. These can vary from person to person. Common triggers include alcohol, stress, smoking, hormonal changes, diseases of the hypothalamus, changing the normal sleep pattern, and certain medications, such as nitroglycerin. Cluster headaches are more common in men than in women.
Making a diagnosis of cluster headache includes performing a complete evaluation that includes a medical history, including symptoms, and physical examination. This includes a neurological examination. A neurological exam evaluates the brain and nerves and such functions as level of consciousness, reflexes, sensation, movement, balance, coordination, vision, and hearing.
Because cluster headaches may cause redness of the eye on the affected side, an eye examination is performed to rule-out such eye conditions as conjunctivitis. Other tests, such as CT scan of the brain, may be performed to help rule-out more serious neurological diseases and conditions with similar symptoms, such as stroke. In some cases, a referral to a neurologist, a specialist in treating neurological conditions, may be needed for definitive diagnosis and treatment of cluster headaches.
The diagnostic process also involves keeping a cluster headache log or diary to record the timing, symptoms, and the types of situations that occurred or substances that were ingested before the cluster headache occurred. This can help to diagnose triggers and assist in making lifestyle changes that can minimize cluster headaches. The type of treatment and its results are also recorded to help pinpoint the most effective treatment for an individual.
It is possible that a diagnosis of cluster headache can be missed or delayed because symptoms can be similar to symptoms of other conditions and diseases, such as migraine, stroke and sinusitis. For more information on diseases and conditions that can mimic cluster headache, refer to misdiagnosis of cluster headache.
Patient compliance with a good treatment plan can control symptoms of cluster headaches to a degree that allows a person to live a normal active life. Treatment plans include medications and avoiding substances and situations that can trigger a cluster headache. For more information on treatment, refer to treatment of cluster headache....more »
