Low-Intensity Pulsed Ultrasound Stimulation Inhibits Cortical Spreading Depression.

Cereb Cortex 2021 Apr 15. Epub 2021 Apr 15.

State Key Laboratory of Cognitive Neuroscience and Learning, Beijing Normal University, Beijing 100875, China.

Cortical spreading depression (CSD), which is closely correlated with migraine aura, cerebral ischemia, seizure, and brain injury, is a spreading wave of neuronal and glial depolarization. The purpose of this study is to investigate whether low-intensity pulsed ultrasound stimulation (PUS) inhibits CSD by modulating neural activity and hemodynamics. Behavioral test, intrinsic signal optical imaging and western blot analysis were used for evaluating the inhibition effect of PUS on CSD in rat. Read More

Neuronal complexity is attenuated in preclinical models of migraine and restored by HDAC6 inhibition.

Elife 2021 Apr 15;10. Epub 2021 Apr 15.

Psychiatry, University of Illinois at Chicago, Chicago, United States.

Migraine is the third most prevalent disease worldwide but the mechanisms that underlie migraine chronicity are poorly understood. Cytoskeletal flexibility is fundamental to neuronal-plasticity and is dependent on dynamic microtubules. Histone-deacetylase-6 (HDAC6) decreases microtubule dynamics by deacetylating its primary substrate, α-tubulin. Read More

Adrenergic inhibition facilitates normalization of extracellular potassium after cortical spreading depolarization.

Sci Rep 2021 Apr 14;11(1):8150. Epub 2021 Apr 14.

Laboratory for Neuron-Glia Circuitry, RIKEN Center for Brain Science, Wako, Saitama, 351-0198, Japan.

Cortical spreading depolarization (CSD) is a propagating wave of tissue depolarization characterized by a large increase of extracellular potassium concentration and prolonged subsequent electrical silencing of neurons. Waves of CSD arise spontaneously in various acute neurological settings, including migraine aura and ischemic stroke. Recently, we have reported that pan-inhibition of adrenergic receptors (AdRs) facilitates the normalization of extracellular potassium after acute photothrombotic stroke in mice. Read More

Transl Behav Med 2021 Apr 5. Epub 2021 Apr 5.

Weight Control and Diabetes Research Center, The Miriam Hospital/Brown Alpert Medical School, Providence, RI, USA.

Given the potential for obesity to complicate migraine treatment outcomes, there is a need to understand patterns and correlates of acute medication use among individuals with this comorbidity. Experience sampling methodology (ESM) was used to characterize patterns of acute medication use among those with migraine and overweight/obesity and to examine individual and momentary factors related to medication use (both migraine-specific and nonspecific medications). Women with migraine and overweight/obesity (N = 170) seeking behavioral migraine treatment completed questionnaires followed by 28 days of daily ESM headache diaries. Read More

Children (Basel) 2021 Mar 17;8(3). Epub 2021 Mar 17.

Division of Pain Medicine, Department of Anesthesiology, Boston Children's Hospital, Boston, MA 02115, USA.

Migraine headache is a common cause of pain and disability in children and adolescents and is a major contributor to frequently missed school days and limitations in activities. Of children and adolescents with migraine headache, approximately one-third have migraine with aura (MA). MA is often considered to be similar to migraine without aura (MO), and thus, many studies do not stratify patients based on the presence of aura. Read More
