Discontinuation of medication is the treatment of choice for patients with chronic daily headache (CDH) who overuse their medications. This treatment may be difficult due to increased headache severity observed in patients immediately after withdrawal. We retrospectively evaluated the efficacy of
The efficacy of valproic acid in the treatment of intractable chronic daily headache, unresponsive to traditional prophylactic medications, was examined prospectively in 16 patients. Dosage of the medication was adjusted to maintain serum valproic acid levels between 50 and 100 micrograms/mL,
Hemicrania continua (HC) is a rare type of primary headache characterized by a prompt and enduring response to indomethacin. We describe a patient who suffered from cluster headache evolving into ipsilateral HC, who does not tolerate a long-term indomethacin therapy. The case was complex in terms of
Cluster headache (CH) pain is the most severe of the primary headache syndromes. It is characterized by periodic attacks of strictly unilateral pain associated with ipsilateral cranial autonomic symptoms. The majority of patients have episodic CH, with cluster periods that typically occur in a
The Treatment Guideline Subcommittee of the Taiwan Headache Society evaluated both the acute and the preventive treatments for cluster headache now being used in Taiwan, based on the principles of evidence- based medicine. We assessed the quality of clinical trials and levels of evidence, and
BACKGROUND
Valproic acid (VPA) is increasingly used to treat a variety of medical disorders, such as seizures, psychiatric disorders, and headaches. Therefore, accidental and intentional ingestions with valproic acid are increasing.
OBJECTIVE
A case is presented in an adolescent with ischemic
Animal models are essential for studying the pathophysiology of headache disorders and as a screening tool for new therapies. Most animal models modify a normal animal in an attempt to mimic migraine symptoms. They require manipulation to activate the trigeminal nerve or dural nociceptors. At best,
BACKGROUND
Topiramate was approved for the treatment of epilepsy in 1999 and has since been approved for the prevention of migraine headache. It is structurally different from the majority of antiepileptic medications and is pharmacodynamically unique in its ability to inhibit the enzyme carbonic
BACKGROUND
Valproic acid, a histone deacetylase inhibitor, has beneficial effects in the setting of cancer, neurologic diseases, and traumatic injuries. In animal models of traumatic injury, a single dose of valproic acid has been shown to reduce mortality. The purpose of this trial was to determine
Valproic acid (VA) is a branch chain fatty acid that is widely used to treat epilepsy and convulsion. Recent studies show that VA can also be used to treat migraine headaches, bipolar disorder, and other diseases such as Alzheimer disease. However, clinical treatment with VA may cause
Valproic acid has been shown to be effective in migraine prophylaxis. Its method of action is believed to be the inhibition of gamma-aminobutyric acid transaminase. The therapeutic dose needed to prevent migraine headaches has been examined in several studies, yet the optimum dose has not been
Cluster headache is characterised by repeated attacks of strictly unilateral pain in the orbital region associated with local autonomic symptoms or signs. The attacks are brief but of a very severe, almost excruciating intensity. For unknown reasons males are affected more often than females. Recent
Valproic acid (VPA) is used worldwide to treat epilepsy, migraine headaches, and bipolar disorder. However, VPA is teratogenic and in utero exposure can lead to congenital malformations. Using inbred C57BL/6J (B6) and DBA/2J (D2) mice, we asked whether genetic variation could play a role in
OBJECTIVE
To explore efficacy and tolerability outcomes of topiramate (TPM) in patients with epilepsy transitioning from valproic acid (VPA) because of insufficient efficacy and/or tolerability onto TPM.
METHODS
Multicenter, open label, single arm, non-interventional study examining patients (> or
OBJECTIVE
To describe a second case of treatment refractory chronic cluster headache responsive to clomiphene citrate and with long-term follow-up.
METHODS
Case report with 7-year evaluation.
METHODS
A 63-year-old man with a 17-year history of chronic cluster headache preceded to have significant
