• #1 Chronic Daily Headache: Diagnosis and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2014/0415/p642.html

  Chronic daily headache is defined as the presence of a headache on 15 days or more per month for at least three months. […] If a red flag for a secondary cause of headache is present, magnetic resonance imaging of the head should be performed. […] Patients who have chronic daily headache should provide a history and have a physical examination with a complete neurologic examination and medication review. […] It is important to evaluate for red flags that may suggest a secondary cause of headache or a headache requiring more immediate evaluation. […] Imaging should be considered if red flags are present. […] The most useful test is magnetic resonance imaging (MRI), which is more sensitive than computed tomography for detecting many secondary causes of chronic daily headache. […] After other secondary causes have been ruled out, the clinical history helps determine what type of primary headache is present.

  Chronic headache is not a single disease entity but an umbrella term that encompasses all chronic headaches. The International Headache Society defines chronic daily headaches (CDH) as „15 or more headache episodes per month for at least three months.” […] A chronic daily headache can be divided into primary and secondary headache disorders depending upon its etiology. Primary chronic headache disorders do not have secondary organic etiology. […] CDH is rather a descriptive term that most encompasses five subtypes of primary and secondary headaches defined by ICHD-3: Chronic migraine headache, Chronic tension-type headache, Medication overuse headache (MOH), Hemicrania continua, New daily persistent headache. […] A thorough history and physical exam are indispensable in the diagnosis of chronic daily headaches. As noted above, a chronic headache should have 15 or more monthly episodes for at least three months.

  Recognition of headache „red flags” is critical in identifying secondary headaches and ordering additional diagnostic testing. […] Further evaluation may not be warranted in a straightforward chronic primary headache disorder. Still, many clinicians will advise baseline laboratory testing and brain imaging to exclude the secondary treatable causes. […] The necessary information that has to be gathered consists of these simple questions: Demographic features of the patient: age, gender, race, profession, When did the headache start? Where does it hurt? Location, irradiation. […] Laboratory workup includes a complete blood count to look for infection. […] Magnetic resonance imaging (MRI) of the brain is the imaging modality of choice. […] Treatment and management of chronic headache disorders depend upon the underlying etiology and may require an interprofessional approach. […] The patient should maintain a headache journal documenting their headache episodes and any accompanying triggers. […] Patient education about the potential for overuse of analgesic medication to lead to headache progression is key. […] The prognosis of chronic headaches is variable.

• #3 Chronic daily headache: Associated syndromes, evaluation, and management – UpToDate

  https://www.uptodate.com/contents/chronic-daily-headache-associated-syndromes-evaluation-and-management

  Chronic daily headache (CDH) is a descriptive term that encompasses several different specific headache diagnoses characterized by frequent headaches. […] Primary CDH subtypes of long duration (ie, four hours or more) include chronic migraine, chronic tension-type headache, hemicrania continua, and new daily persistent headache. Medication overuse headache, a secondary headache disorder, frequently complicates management of multiple primary headache disorders. […] CDH is not a specific headache type, but a descriptive term that encompasses other primary and secondary headaches. The term „chronic” in CDH refers either to the frequency of headaches or to the duration of the disease, depending upon the specific headache type.

• #4 Chronic daily headaches – Diagnosis and treatment – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/chronic-daily-headaches/diagnosis-treatment/drc-20370897

  Your doctor will likely examine you for signs of illness, infection or neurological problems and ask about your headache history. […] If the cause of your headaches remains uncertain, your doctor might order imaging tests, such as a CT scan or MRI, to look for an underlying medical condition. […] Treatment for an underlying condition often stops frequent headaches. If no such condition is found, treatment focuses on preventing pain. […] The use of one drug is preferred, but if one drug doesn’t work well enough, your doctor might consider combining drugs. […] You’re likely to start by seeing your family doctor or a general practitioner. However, you may be referred to a headache specialist. […] Your doctor is likely to ask you questions, such as: Have your headaches been continuous or occasional? How severe are your headaches? What, if anything, seems to improve your headaches? What, if anything, appears to worsen your headaches?

• #5 1.3 Chronic migraine – ICHD-3

  https://ichd-3.org/1-migraine/1-3-chronic-migraine/

  Characterization of frequently recurring headache generally requires a headache diary to record information on pain and associated symptoms day-by-day for at least one month. […] Because tension-type-like headache is within the diagnostic criteria for 1.3 Chronic migraine, this diagnosis excludes the diagnosis of 2. Tension-type headache or its types. […] The most common cause of symptoms suggestive of chronic migraine is medication overuse, as defined under 8.2 Medication-overuse headache.

• #5 1.3 Chronic migraine – ICHD-3

  https://ichd-3.org/1-migraine/1-3-chronic-migraine/

  Headache occurring on 15 or more days/month for more than 3 months, which, on at least 8 days/month, has the features of migraine headache. […] Diagnostic criteria: Headache (migraine-like or tension-type-like) on ≥15 days/month for >3 months, and fulfilling criteria B and C. […] Occurring in a patient who has had at least five attacks fulfilling criteria B-D for 1.1 Migraine without aura and/or criteria B and C for 1.2 Migraine with aura. […] On ≥8 days/month for >3 months, fulfilling any of the following: criteria C and D for 1.1 Migraine without aura; criteria B and C for 1.2 Migraine with aura; believed by the patient to be migraine at onset and relieved by a triptan or ergot derivative. […] Not better accounted for by another ICHD-3 diagnosis. […] The reason for singling out 1.3 Chronic migraine from types of episodic migraine is that it is impossible to distinguish the individual episodes of headache in patients with such frequent or continuous headaches.

  Features that represent a warning for a possible underlying disorder causing the headache are new onset headache, change in previously stable headache pattern, headache that abruptly reaches the peak level, headache that changes with posture, headache awakening the patient, or precipitated by physical activity or Valsalva manoeuvre, first onset of headache 50 years of age, neurological symptoms or signs, trauma, fever, seizures, history of malignancy, history of HIV or active infections, and prior history of stroke or intracranial bleeding.

• #6 (PDF) Diagnostic testing for chronic daily headache

  https://www.academia.edu/127304629/Diagnostic_testing_for_chronic_daily_headache

  Primary chronic headaches of long duration include chronic migraine, chronic tension-type headache, new daily persistent headache, and hemicrania continua. This article reviews the utility of neuroimaging and other testing for diagnosis of these headaches. […] Although the yield of diagnostic testing is low, serious pathology as a cause of chronic headaches can be easily overlooked. […] The objective of this study was to determine the primary headache diagnosis among a population of chronic daily headache patients attending a tertiary center for headache treatment. […] A systematic approach to the diagnosis of primary and secondary headache disorders requires the measurement of the frequency and the duration of headache. […] The diagnosis of primary headache disorders is clinical and based on the diagnostic criteria of the International Headache Society (ICHD-3-beta). However several brain conditions may mimic primary headache disorders and laboratory investigation may be needed.

• #7 New Daily Persistent Headache

  https://practicalneurology.com/diseases-diagnoses/headache-pain/new-daily-persistent-headache/31897/

  New daily persistent headache (NDPH) is among the most underrecognized and undertreated headache disorders. The International Classification of Headache Disorders, 3rd edition (ICHD-3) defines NDPH by its distinct onset, which becomes constant and unremitting within a day. […] The diagnosis of NDPH does not include proven causes of secondary headache (eg, cerebrospinal fluid [CSF] hypertension or hypotension, vascular or traumatic brain injury, or central nervous system [CNS] infection). […] Individuals who have signs or symptoms suggesting serious secondary headache should have a prompt reevaluation of their NDPH diagnosis. Presentations of serious secondary headaches include fever, papilledema, progressive headache, confusion, severe medical disease, and focal neurologic findings on examination.

• #8 Diagnosing Headache | NYU Langone Health

  https://nyulangone.org/conditions/headache/diagnosis

  To determine the type of headache causing your pain, neurologists at NYU Langone ask about your headache history and symptoms, focusing on the frequency, intensity, duration, location, and any known triggers. Your doctor also conducts a comprehensive review of your medical history and family history of headache and performs a physical exam to obtain a complete picture of your health. […] Depending on your symptoms and the results of your medical and neurologic examinations, your physician may recommend further diagnostic testing. Your doctor may use one or more of the following tests to arrive at the most accurate diagnosis. […] MRI uses magnetic waves and computers to create two- or three-dimensional images. Your doctor may order an MRI scan to view the inside of the head and neck. This can reveal the presence of other conditions that can cause headaches, such as a tumor or abscess, which is a collection of pus that has formed in response to an infection.

  https://nyulangone.org/conditions/headache/diagnosis

  A magnetic resonance angiogram, or MRA, is similar to an MRI scan. Its an imaging technique that is used to check for an abnormality, such as an aneurysm, in the blood vessels of the brain. […] NYU Langone specialists use the results of these tests, along with their clinical judgment and skills, to craft a treatment plan to alleviate your symptoms. If your doctor determines that your headaches are caused by a secondary condition, he or she may recommend that the underlying condition be treated first to see if this stops the headaches from occurring. […] If you are diagnosed with primary headaches, our physicians can offer a variety of treatment options, including medications and a nerve block procedure, that may reduce or eliminate your symptoms.

• #10 Headaches | Migraines – Causes, Diagnostic Tests and Treatment

  https://www.radiologyinfo.org/en/info/headache

  Your doctor may order head MRI, head CT or lumbar puncture to help diagnose and evaluate your condition. […] To diagnose the cause of headaches and to rule out underlying medical conditions, physicians obtain a patient history and conduct a careful neurological examination. Diagnostic testing may include the following imaging tests: […] CT imaging of the head: Computed tomography (CT) scanning combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. […] MRI of the head: Magnetic resonance imaging (MRI) uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. […] Lumbar puncture (also called a spinal tap): This diagnostic test involves removing and analyzing a small amount of cerebrospinal fluidthe fluid that surrounds the brain and spinal cord from the lumbar (or lower) region of the spinal column. […] If your doctor suspects you may have an aneurysm, you may undergo CT Angiography.

• #12 New Daily Persistent Headache (NDPH): Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/24098-new-daily-persistent-headache-ndph

  Diagnosing NDPH is a multistep process. […] The first step is to gather information about your symptoms, including how long you’ve had the headache, when it started and what you’re feeling from it. […] The second step is to rule out other causes of the headache. […] After the first step is complete, the healthcare provider needs to make sure there isn’t another cause for NDPH. […] Its common for people to seek medical care before they reach the three-month requirement for having NDPH. […] In these cases, your provider will go through all the same diagnostic steps but won’t finalize the diagnosis. […] In these instances, your provider will diagnose you with probable NDPH. […] Once you reach three months with symptoms, they can formally diagnose you with NDPH. […] There aren’t any tests that can directly diagnose NDPH.

• #13 Diagnosis of Primary Chronic Daily Headaches | SpringerLink

  https://link.springer.com/chapter/10.1007/978-1-4614-0179-7_3

  Chronic daily headache (CDH) is a term of art meaning headaches present at least 15 days/month, at least 4 h/day untreated, present at least 3 months. […] CDH is generally primary, but many clinicians include Medication Overuse Headache (MOH) in the term. […] The four primary chronic daily headaches are: Chronic Tension-Type Headache (CTTH), Hemicrania Continua (HC), New Daily Persistent Headache (NDPH), and Chronic Migraine (CM). […] CTTH is a low level, featureless headache, almost never with impact. […] HC is a unilateral, mild to moderate headache with periodic severe exacerbations, accompanied by autonomic signs. […] NDPH is probably best diagnosed as abrupt onset primary CDH of any phenotype. […] Primary CM is a primary CDH in which a patient transforms from episodic migraine to CDH without secondary causes, thereby excluding medication overuse. […] MOH is not a primary CDH; it is characterized by overuse of enough acute medication to transform a patient to secondary CDH. […] The FDA defined chronic migraine as CDH, both primary and secondary.

  Chronic headache with acute onset; de novo chronic headache. […] Persistent headache, daily from its onset, which is clearly remembered. The pain lacks characteristic features, and may be migraine-like or tension-type-like, or have elements of both. […] Diagnostic criteria: Persistent headache fulfilling criteria B and C; Distinct and clearly-remembered onset, with pain becoming continuous and unremitting within 24 hours; Present for >3 months; Not better accounted for by another ICHD-3 diagnosis. […] 4.10 New daily persistent headache is unique in that headache is daily from onset, and very soon unremitting, typically occurring in individuals without a prior headache history. Patients with this disorder invariably recall and can accurately describe such an onset; if they cannot do so, another diagnosis should be made. […] In all cases, other secondary headaches such as Acute headache attributed to traumatic injury to the head, Headache attributed to increased cerebrospinal fluid pressure and Headache attributed to low cerebrospinal fluid pressure should be ruled out by appropriate investigations.

• #15 Chronic daily headaches – Symptoms and causes – Mayo Clinic

  Most people have headaches from time to time. But if you have a headache more days than not, you might have chronic daily headaches. […] By definition, chronic daily headaches occur 15 days or more a month, for longer than three months. True (primary) chronic daily headaches aren’t caused by another condition. […] The causes of many chronic daily headaches aren’t well-understood. True (primary) chronic daily headaches don’t have an identifiable underlying cause. […] Conditions that might cause nonprimary chronic daily headaches include: Inflammation or other problems with the blood vessels in and around the brain, including stroke, Infections, such as meningitis, Intracranial pressure that’s either too high or too low, Brain tumor, Traumatic brain injury. […] This type of headache usually develops in people who have an episodic headache disorder, usually migraine or tension type, and take too much pain medication. If you’re taking pain medications even over-the-counter more than two days a week (or nine days a month), you’re at risk of developing rebound headaches.

  Chronic daily headache is not a type of headache but a category that includes frequent headaches of various kinds. […] When a headache is present for more than 15 days per month for at least three months, it is described as a chronic daily headache. […] Most people with chronic daily headache have migraine or tension-type headache as the underlying type of headache. […] Some people with frequent headache use headache medications too often, which can lead to „medication-overuse headaches.” […] Health care providers typically use a person’s description of their headache, in combination with an examination, to determine the type of headache. […] Most people do not need X-rays or other imaging tests. A computed tomography (CT) scan (or magnetic resonance imaging [MRI]) may be recommended in some circumstances, for example, if symptoms are unusual, if there are any danger signs, or if there are any abnormalities seen during the examination.

  Chronic daily headache (CDH) is a descriptive term that encompasses multiple headache diagnoses and affects ~4% of the general adult population. […] For CDH management to succeed, secondary headaches need to be ruled out with proper investigations when judged necessary. If the diagnosis of primary CDH is established, diagnosis of the specific CDH subtype is imperative to institute appropriate treatment. […] The diagnosis and management of distinct CDH entities, chronic migraine, chronic tension-type headache, new daily persistent headache, and hemicrania continua, are the primary forms of CDH and the emphasis of this review. […] Although, strictly speaking, medication overuse headache is a secondary form of CDH, it is also highlighted in this review given its frequent association with primary CDH.
