Clinical features of new daily persistent headache: A retrospective chart review of 328 cases.

OBJECTIVE: To describe the clinical features of new daily persistent headache (NDPH) at an outpatient neurology clinic with a subspecialty interest in headache in Houston, Texas. METHODS: A retrospective chart review was performed by a neurologist subspecialty certified in headache medicine of all patients seen from September 1, 2011 through February 28, 2020 (8.5 years) with a provisional diagnosis of NDPH and abstracted charts meeting criteria for primary NDPH. RESULTS: A total of 328 patients met the International Classification of Headache Disorders, 3rd edition criteria including 215 (65.5%) female patients. The mean age of onset was 40.3 years (range 12-87 years) with a mean age at first consultation in the study clinic of 42.6 years (range 12-87 years). The median [25th, 75th] duration of NDPH at initial consultation was 0.7 [0.3, 2.0] years, and at last visit, it was 1.9 [0.7, 4.8] years. The headaches were side-locked unilateral in 28/328 (8.5%). 12/328 cases (3.6%) with a thunderclap onset are reported. There was no obvious seasonal or other cyclical variation. The pain was usually moderate to severe and more often severe for the migraine phenotype (MP; 260/328 [79.3%] of cases) than for the tension-type phenotype (TTP). Precipitating factors were the following: stressful life events, 67/328 (20.4%); upper respiratory infection or flu-like illness, 33/328 (10.1%); and extracranial surgery, 5/328 (1.5%). Exacerbating or aggravating factors similar to migraine triggers were more often reported with the MP than with the TTP in this sample. For the MP, vertigo or dizziness was reported by 19/260 (7.3%) and a visual aura by 21/260 (8.1%) with descriptions provided. The prognostic types were the following for all patients: persisting (refractory), 305/328 (93.0%); relapsing-remitting, 9/328 (2.7%); and remitting (self-limited), 14/328 (4.3%). CONCLUSION: NDPH is typically of moderate to severe intensity often with migraine features without obvious seasonal or other cyclical variation. Most cases are refractory. 3.6% have a thunderclap onset often with a good response to treatment.

Incidental Findings and Normal Anatomical Variants on Brain MRI in Children for Primary Headaches.

When MRI scans of the brain are obtained for evaluation of primary headaches in children, incidental findings and anatomical variants are commonly present. After a review of the prevalence, 11 types are presented.

Incidental Findings and Normal Anatomical Variants on MRI of the Brain in Adults for Primary Headaches.

When MRI scans of the brain are obtained for evaluation of primary headaches in adults, incidental findings are commonly present. After a review of the prevalence of incidental findings and normal anatomical variants, 21 types are presented.

Headache and arachnoid cysts.

Arachnoid cysts are commonly encountered when neuroimaging is obtained for headaches. Their clinical relevance is not always immediately clear and they may confound medical management.

New daily persistent headache.

Primary new daily persistent headache is a rare disorder of children and adults defined by the onset of daily and unremitting headaches within 3 days of onset lasting 4 hours or more daily. There may be a link between a preceding flu-like or upper respiratory infection in about 15%, a stressful life event in 10%, or extracranial surgery in 10%. Migraine symptoms may be present in over 50%. The headache is generalized in most but may be unilateral in 11% and may be localized to any head region. The diagnosis is one of exclusion as many secondary etiologies can cause similar headaches. The pathophysiology of the primary type is unknown. There are no prospective placebo controlled trials of preventive treatment so prevention is empiric using the same medications for the phenotype of chronic migraine or tension-type headache. Most patients have persistent headaches, although about 15% will remit, and 8% will have a relapsing-remitting type.

Migraine: a question and answer review.

Internists commonly treat migraine, which affects more than 29 million Americans yearly. This article reviews epidemiology, pathophysiology, comorbidity, clinical features, diagnostic testing, acute and preventive treatment, and women's issues. Physicians and migraineurs would like to see more effective and more tolerable medications.

Hemicrania Continua-like headache due to nonmetastatic lung cancer--a vagal cephalalgia.

A 72-year-old man presented with a 7-week history of a new onset constant severe right-sided headache associated with redness and tearing of the right eye, which resolved on indomethacin due to nonmetastatic small cell carcinoma producing a large suprahilar mass. This is the first case report of a hemicrania continua-like headache with autonomic features due to lung cancer. I propose the term "vagal cephalalgia" to include headache and/or facial pain due to nonmetastatic lung cancer and cardiac cephalalgia which result from vagal afferent stimulation.

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. The presentation and diagnosis of the many secondary headaches that can mimic primary headache types are also discussed, including arteriovenous malformations, spontaneous intracranial hypotension, neoplasms, pseudotumor cerebri, cervical artery dissections, cerebral venous thrombosis, Chiari I malformation, and temporal arteritis. Although the yield of diagnostic testing is low, serious pathology as a cause of chronic headaches can be easily overlooked.
