• Throbbing Headache

  Bathing headache is rarely described in literature. We report four middle-aged Taiwanese women who developed severe throbbing headache with maximum intensity of onset during bathing. Diffuse cerebral vasospasm was demonstrated in one of them. [ncbi.nlm.nih.gov]

  While this won’t get rid of your thunderclap headache, it may at least reduce its severity. Take Belladonna Belladonna is a homeopathic tincture which can be useful in treating thunderclap headaches, as well as other types of throbbing headaches. [askdrjj.com]

Nimodipine might be effective in treatment of this special headache syndrome. [ncbi.nlm.nih.gov]

Treatment and prognosis depend on the etiology of the TCH. [ncbi.nlm.nih.gov]

Idiopathic thunderclap headache with vasospasm must also be distinguished from inflammatory CNS vasculitis, as the outcome, management, and prognosis are different. [doi.org]

Subarachnoid hemorrhage is the most commonly identified etiology for this headache, however, other secondary etiologies should be considered. [ncbi.nlm.nih.gov]

There are numerous etiologies of thunderclap headache, some associated with substantial morbidity and mortality and others with benign outcomes. [headachejournal.onlinelibrary.wiley.com]

Numerous etiologies for thunderclap headaches have been identified, with the most common causes being subarachnoid hemorrhage and reversible cerebral vasoconstriction syndrome. [journals.lww.com]

There is a need for an up to date population based description of cause of sudden and severe headache as the modern epidemiology of thunderclap headache may require updating in the light of research on cerebral vasoconstriction syndromes. [ncbi.nlm.nih.gov]

To gain insights into the epidemiology, clinical range, pathophysiology, appropriate management, and prognosis of patients with this disorder, clinical criteria must be established to create homogenous patient populations to study in a prospective fashion [dx.doi.org]

The pathophysiology of this disorder in the absence of underlying pathology is not well understood and its potential angiographic features are not well appreciated. Two case descriptions with illustrative angiography. [ncbi.nlm.nih.gov]

PATHOPHYSIOLOGY The pathophysiology or mechanism(s) underlying idiopathic thunderclap headache with or without segmental vasospasm is unclear. [doi.org]

Include Blood-Thinning Vegetables Garlic, onions, and peppers are all known to act as blood thinners, which can help prevent blood clots as well as reduce their severity. Because thunderclap headaches can be caused by blood clots, this makes sense. [askdrjj.com]

However, when cerebral vasospasm is present, careful clinical monitoring is important and although the evidence is purely anecdotal, nimodipine may be used in an attempt to prevent or ameliorate the risk of a delayed ischaemic deficit. 45 Although these [doi.org]
