OTHER PRIMARY HEADACHES: TENSION-TYPE, STABBING, HYPNIC AND NUMMULAR HEADACHE TENSION-TYPE HEADACHE Deborah I. Friedman, MD, MPH University of Texas Southwestern Medical Center Dallas, TX The most common primary headache disorder in the general population In adults, affects slightly more women than men with peak prevalence between 30-39 years In children, girls and boys are equally affected Risk factors: Female sex, arterial hypertension, history of head trauma, family history of headache, being a student Risk factors in medical students: dissatisfaction with study (males), depressed mood (females) High prevalence of temporomandibular joint disease and widespread pain sensitivity Trigger points in the head, neck and shoulder, while common, are not related to headache frequency Usually bilateral pain If unilateral, consider hemicrania continua, mild migraine, nummular headache or giant cell arteritis in the elderly Pressing, tightening, vice like, tight band, or aching pain May involve the neck and shoulders Usually mild to moderate in intensity Not aggravated by routine physical activity (helps distinguish from migraine) No nausea or vomiting Lasts 30 minutes to 7 days When severe, tension-type headache may one of the following mild migrainous features: Photophobia Phonophobia Nausea Throbbing No aura or premonitory symptoms May be triggered by stress, lack of sleep, fatigue, missing meals Frequency < 1 day per month (<12 days per year) = Infrequent tension-type headache Frequency < 15 days monthly for at least 3 months = Episodic tension-type headache Frequency > 15 days monthly for at least 3 months = Chronic tension-type headache Chronic tension-type headache Treatment: Acute: Acetaminophen/paracetamol (1000 mg) Aspirin (500-1000 mg) associated with less frequent rescue medication compared to placebo but there is limited evidence from clinical studies NSAIDS: ibuprofen 200-800 mg, ketoprofen 25 mg, naproxen (250-500 mg) Combination medications: Caffeine/acetaminophen/aspirin, butalbital compound (high risk of medication overuse)

Preventive: Tricyclic antidepressants (amitriptyline up to 75 mg, highest level of evidence) Tizanidine (12-24 mg daily) Selective serotonin/norepinephrine reuptake inhibitors (venlafaxine 150 mg daily) Mirtazepine (30 mg HS) Behavioral treatments (biofeedback, cognitive-behavioral therapy, relaxation training) Combined medical and behavior treatment seems most effective Acupuncture has moderate to low quality evidence supporting its use (mostly because of blinding) and may decrease the number of headache days Lebedeva ER, Kobzeva NR, Gilev DV, Olesen J.

Eur J Integr Med 2016;8:234-5 PRIMARY STABBING HEADACHE May occur in patients with other types of headaches (migraine, cluster, hemicranias continua, paroxysmal hemicranias) Onset at any time during life; childhood onset is not uncommon Population prevalence <2% Described as stabbing, pricking, sharp, ice pick, jabs and jolts, lightning pain, severe pain Sudden, spontaneous attacks of fleeting head pain lasting 1-10 seconds Usually in V1, but may occur anywhere on the head Unilateral, bilateral, often varying in location Frequency varies widely Usually no associated symptoms or autonomic features Although brief, the abruptness and severity causes distress that there is a serious underlying problem When associated with cluster, stabs are usually ipsilateral to the side of the cluster pain and may resemble trigeminal neuralgia. The stabbing pains may occur with partially effective treatment of cluster headache or just before a cluster bout begins. Secondary causes: Giant cell arteritis Cerebral or pituitary neoplasms Encephalitis Autoimmune disorders Pseudotumor cerebri syndrome

Treatment: Preventive treatment is only needed if frequency and patient distress are high May subside spontaneously over time Indomethacin is first choice Others: cyclo-oxygenase type 2 inhibitors, melatonin, gabapentin, amitriptyline, onabotulinumtoxin A Robbins MS, Evans RW.

HYPNIC HEADACHE Rare, usually begins after age 50 (mean 61 years, range 30-83 years) 65% are women Rare reports in childhood Features Develops only during sleep (not circadian, per se) Headache occurs at a consistent time each night, usually 0100-0300, and rarely after a daytime nap Alarm clock headache Abrupt onset of diffuse, throbbing pain lasting 15-180 minutes (rarely lasts up to 10 hours) Mild to moderate in intensity May be unilateral Usually located anteriorly but may involve the occiput or neck Most patients have at least 4 attacks weekly (range 1 per week to 6 per night) Rarely accompanied by associated symptoms or autonomic features Reports in children: Pain was usually bilateral, lasting up to 30 minutes, throbbing, severe and usually occurred less than 15 days monthly A retrospective study of 40 adult with hypnic headache found that the mean age at onset was 62, 80% were women, and most described their headaches as severe and burning (Tariq). Headaches occurred with a mean frequency of 21 days monthly (range 5-30) lasting a mean of 186 minutes (range 30-720). Only 3 patients had trigeminal autonomic features but 9 had migrainous features. Over half had a prior history of headache, most frequently migraine. Comorbidities included hypertension (52%), hypothyroidism (25%), a history of smoking (37%), vitamin D deficiency (28%) and history of concussion or traumatic brain injury (27%). 22% noted that physical activity or exercise immediately after awakening decreased the intensity of their headaches. Patients were followed for a mean of 3 years. Of the many medications tried, the only ones that produced a complete response (in some patients) were caffeine, lithium and melatonin. However, caffeine responsiveness was often not sustained over time. Neuroimaging in 33 patients showed no secondary cause. Hints in the history Nocturnal awakening in cluster headache also has an alarm clock quality and may have similar duration. Differentiate from cluster by severity (hypnic is less severe), lack of agitation and lack of autonomic symptoms. The paroxysmal hemicranias are less likely to cause nocturnal awakening than cluster, but it can occur. Headaches are briefer than cluster. Secondary causes: Nocturnal hypertension this has been found in patients with hypnic headache Medication overuse a common cause with the medication wears off Sleep apnea also associated with lack of the normal nocturnal dip in blood pressure. Nocturnal Hypoglycemia Brain tumor or increased intracranial pressure definitely consider when patient is under age 50. It is rare for brain tumors to present with headache only. Funduscopy and imaging are recommended for all patients who do not have the typical phenotype of hypnic headache.
