A recent study reveals that migraine patients exhibit altered tactile sensation, particularly a decreased perception of pleasure in gentle touch. The research suggests that this disturbance may be related to the same neurophysiological processes underlying allodynia, a common symptom of migraine.
Pre-clinical studies reveal that cortical spreading depression and calcitonin gene-related peptide (CGRP) play significant roles in migraine. Botox, CGRP, and PACAP-38 show promise as potential treatments.
Trigeminal nerve and hippocampus volumes predict successful surgical treatment outcomes, with non-responders showing larger intracranial volume and contralateral hippocampus volume. The study suggests that neuroanatomical features may be key to understanding chronic pain resistance.
Researchers found structural brain connectivity changes between migraine patients and healthy volunteers, as well as between episodic and chronic migraine patients. Strengthening connectivity was observed in areas implicated in migraine's pathophysiology, while weakening connectivity patterns were seen in the temporal lobe of migraine ...
A recent meta-analysis published in Cephalalgia highlights the predictors of chronic migraine, including depression, which increases the risk by 58%, and high-frequency attacks, which raises a permanent debate surrounding the diagnostic criteria. The study also found medication overuse to increase the odds of developing chronic migrain...
A study found that cluster headache attacks exhibit a dynamic circadian and seasonal pattern, with changes in the attack timing throughout the disease course. Patients with more lifetime bouts showed a less variable pattern compared to those without circadian rhythmicity.
A study found that nitroglycerin infusion triggers abnormal cardiovascular responses in migraine patients, including higher heart rates and reduced stroke volume. The findings suggest a systemic susceptibility to the vasodilatory effects of nitroglycerin, possibly due to enhanced sensitivity to nitric oxide.
A recent study published in Cephalalgia found that calcitonin gene-related peptide (CGRP) and sildenafil both provoke migraine attacks in patients, with no differences in clinical characteristics. The study suggests that these drugs may act through a single molecular pathway, offering potential for new preventive therapeutics.
A recent study published in Cephalalgia highlights an overlooked relationship between migraine and exercise. Anxiety sensitivity is found to be associated with physical activity avoidance in women with probable migraine, particularly with vigorous intensity.
Cinnarizine and sodium valproate show promise as preventive agents for pediatric migraine, reducing headache frequency by over 50% compared to placebo. The study suggests these medications may be a new option for children and adolescents with migraine, but long-term safety concerns need further investigation.
A study found that half of adults experienced headaches after consuming a cold stimulus, with moderate pain lasting less than 30 seconds. The pleasure of eating ice cream or drinking cold drinks may be reduced due to painful headaches.
