Cluster headaches cause excruciating, unilateral periorbital or temporal pain, with ipsilateral autonomic symptoms (ptosis, lacrimation, rhinorrhea, nasal congestion). Diagnosis is clinical. Acute treatment is with parenteral triptans, dihydroergotamine, or oxygen. Prevention is with verapamil, lithium, topiramate, divalproex, galcanezumab (a monoclonal antibody), or a combination.

Cluster headache affects primarily men, typically beginning at age 20 to 40; prevalence in the US is 0.4%. Usually, cluster headache is episodic; for 1 to 3 months, patients experience 1 attack/day, followed by remission for months to years. Some patients have cluster headaches without remission.

Pathophysiology is unknown, but the periodicity suggests hypothalamic dysfunction.

Alcohol intake triggers cluster headache during the attack period but not during remission.

Symptoms and Signs of Cluster Headache

Symptoms of cluster headache are distinctive. Attacks, often multiple, frequently occur at the same time each day, often awakening patients from sleep.

When attacks occur, pain is always unilateral and occurs on the same side of the head in an orbitotemporal distribution. It is excruciating, peaking within minutes; it usually subsides spontaneously within 30 minutes to 1 hour. Patients are agitated, restlessly pacing the floor, unlike migraine patients who prefer to lie quietly in a darkened room. The restlessness can be so severe that it leads to bizarre behavior (eg, banging the head on a wall).

Diagnosis of Cluster Headache

  • Clinical evaluation

Diagnosis of cluster headache is based on the distinctive symptom pattern and exclusion of intracranial abnormalities.

Other unilateral primary headache syndromes with autonomic symptoms, which are sometimes grouped together with cluster headache as trigeminal autonomic cephalgias, should be excluded:

Chronic paroxysmal hemicrania and hemicrania continua, unlike SUNCT and cluster headache (and migraine Migraine Migraine is an episodic primary headache disorder. Symptoms typically last 4 to 72 hours and may be severe. Pain is often unilateral, throbbing, worse with exertion, and accompanied by symptoms... read more ), respond dramatically to indomethacin, but not to other nonsteroidal anti-inflammatory drugs (NSAIDs).

Treatment of Cluster Headache

  • For aborting attacks, parenteral triptans, dihydroergotamine, or 100% oxygen

  • For long-term prophylaxis, verapamil, lithium, topiramate, divalproex, or a combination or galcanezumab (a monoclonal antibody) for episodic cluster

All patients require preventive drugs because cluster headache is frequent, severe, and incapacitating. Prednisone (eg, 60 mg orally once a day) or a greater occipital nerve block (with a local anesthetic and a corticosteroid) can provide prompt temporary prevention while preventive drugs with slower onset of action (eg, verapamil, lithium, topiramate, divalproex) are initiated.

Noninvasive transcutaneous supraorbital nerve stimulation delivered using a device applied to the forehead can reduce the frequency of cluster headaches, as can noninvasive vagus nerve stimulation (3 Treatment reference Cluster headaches cause excruciating, unilateral periorbital or temporal pain, with ipsilateral autonomic symptoms (ptosis, lacrimation, rhinorrhea, nasal congestion).

Thiamine Deficiency
Thiamin deficiency causes beriberi. It is most common among patients with alcoholism and people subsisting on white rice or highly refined carbohydrates. Early symptoms of all types of beriberi are nonspecific and include fatigue, poor memory, anorexia, and abdominal discomfort. As beriberi progresses, different forms of this condition cause different symptoms. Of these symptoms, which of the following is most indicative of dry beriberi?
